Authors: Dihansih Elis , Handarini Ristika , Haerina Nina
Published: April 2018

The meat of local ducks generally has lower quality than chicken meat. Typical aroma, dark red color, and hard texture of duck meat affect consumers’ preference for it. This study was aimed at assessing the sensoric quality of meat of male local ducks(Anas plathyrhinchos) given betle (Piper betle Linn) leaf extract solution included in commercial ration. The study was conducted at the Poultry Farm of Department of Animal Husbandry, Faculty of Agriculture, Djuanda University, Bogor from June to August 2016. Twenty-four male local ducks aged 2 weeks with average body weight of 449.16±75.27 g were used. BR-21E commercial feed of PT Sinta Feedmill and betel leaf extract solution were used. A completely randomized design with 4 treatments and 3 replicates was used. Treatments consisted of 100% commercial feed (R0), commercial feed + 2.5% piper betel solution (R1), commercial feed + 5.0% piper betel solution (R2), and commercial feed + 7.5% piper betel solution (R3). Data were subjected to a Kruskal Wallis test. Measurements were taken on aroma, tenderness, color, taste, and juiceness. Results showed that there were significant differences (P<0.05) in color and taste. The inclusion of 2.5% piper betle extract solution in commercial rations improved the preference of panelists for the color and taste of meat of local ducks. However, treatments did not affect panelists judgement on the hedonic quality (aroma, tenderness, color, taste, and juiceness) of meat of local ducks.

Linseed is an industrial crop cultivated for its seeds, fibres and oil purpose. Linseed crop can met their requirement i.e. moisture and nutritional demand from stored soil moisture and residual fertility status in "utera? or "paira? system of cropping. On the basis of this fact an experiment was conducted on “Seed yield of linseed varieties grown as paira crop as influenced by dates of sowing” in red and laterite zone of West Bengal during rabi season of 2012-13 and 2013-14 at Rice Research Station, Bankura, West Bengal, India. Poor in organic matter content, available phosphate and bases, hard structure of iron and aluminium patterned as honeycomb are present in the subsurface regions of the profiles and kaolinite is the predominant clay minerals of red and lateritic zone (western part) of West Bengal. This experiment was laid out in a split-plot design with three replications and compared two factors (dates of sowing and linseed varieties). Objective was identifying the optimum date of sowing and suitable linseed varieties grown as „paira? crop under changed climate in red and laterite zone of West Bengal. The experimental results revealed that the highest seed yield (534 kg ha-1 as pooled value) was recorded from the treatment D1 i.e. linseed sown on 15th November. The lowest seed yield (489.2 kg ha-1 as pooled value) was obtained with treatment D3 i.e. linseed sown on 29th November. Among linseed varieties, T-397 has yielded highest seed yield (573.4 kg ha-1 as pooled value). Lowest seed yield (409. 3 kg ha-1 as pooled data) was recorded from Neela variety. From the present study it may be concluded that linseed sown on 15th November is the best time and T-397 is the suitable linseed variety grown as "paira? crop under changed climate in red and laterite zone of West Bengal.
Determination of the Order of a Markov Chain for Daily Rainfall Data of North East India: "Application AIC criterion"
Authors: Deka Surobhi
Published: April 2018

The paper aims at demonstrating the application of the Akaike information criterion to determine the order of two state Markov chain for studying the pattern of occurrence of wet and dry days during the rainy season (April to September) in North-East India. For each station, each day is classified as dry day if the amount of rainfall is less than 3 mm and wet day if the amount of rainfall is greater than or equal to 3 mm. We apply Markov chain of order up to three to the sequences of wet and dry days observed at seven distantly located stations in North East region of India. The Markov chain model of appropriate order for analyzing wet and dry days is determined. This is done using the Akaike Information Criterion (AIC) by checking the minimum of AIC estimate. Markov chain of order one is found to be superior to the majority of the stations in comparison to the other order Markov chains. More precisely, first order Markov chain model is an adequate model for the stations North Bank, Tocklai, Silcoorie, Mohanbari and Guwahati. Further, it is observed that second order and third order Markov chains are competing with first order in the stations Cherrapunji and Imphal, respectively. A fore-knowledge of rainfall pattern is of immense help not only to farmers, but also to the authorities concerned with planning of irrigation schemes. The outcomes are useful for taking decisions well in advance for transplanting of rice as well as for other input management and farm activities during different stages of the crop growing season.

Published: April 2018

Three biocontrol agents viz., Trichoderma viride, T. virens and T. harzianum were evaluated to test the antagonism against Sclerotium rolfsii under in vitro conditions. All the three antagonists’ viz., T. viride, T. virens and T. harzianum have shown the potential of parasitizing the growth of Sclerotium rolfsii in vitro. The rate of inhibition was fastest in T. harzianum (63.60%) followed by T virens (51.5 %). Least inhibition was recorded in T. viride (50.85% ) after 72 hours of incubation. However, T. viride showed the highest (91.31%) reduction in sclerotia formation followed by T. harzianum (84.92%) and T. virens (84.29%) after 15 days of incubation. The volatile compounds from Trichoderma viride were found most effective in suppressing the mycelial growth (51.11%) and sclerotia production (95.90%) of the target pathogen. The culture filtrate from both T. harzianum and T. viride (15% concentration) was found very effective in inhibiting the radial growth (57.46 and 49.62%) and sclerotia formation (98.20 and 99.83%) of Sclerotium rolfsii. The antagonists such as T. harzianum and T. viride can be used as a bio-control agent against S. rolfsii under field condition.

Published: April 2018

Each year, thousands of individuals are diagnosed with an illness directly related to poorly designed workstations, and among these are Musculoskeletal Disorders (MSDs). MSDs are the repeated trauma and deterioration of the tissues, joint, tendons, and nerves that affect the muscles and supporting structures of the body, caused by the work nature or by an employee’s working environment (Bernard 1997). The prevalence of Work-related Musculoskeletal Disorders (WMSD‘s) is increasing among Computer users throughout the world. Approximately 76% of Computer professionals from India reported musculoskeletal discomfort in various epidemiological studies. So, the present study was undertaken to study computer/laptop use pattern and knowledge of related ergonomic practices among students of Punjab Agricultural University (PAU), Ludhiana, India and to assess the prevalence and magnitude of computer/laptop use related MSDs among students. 120 students pursuing post-graduation were selected randomly from the four different disciplines namely College of Agriculture, College of Agriculture Engineering and Technology, College of Basic Sciences and Humanities and College of Home Science of PAU. Results revealed that majority of the respondents were in the age group of 26-27 years. They were using computer/laptop for 3-4 years, for 3-4 hours daily and they used to sit in bed while working on computer/laptop. Majority of the respondents had some knowledge about the importance of work behavior while using computer/laptop. Most of the total respondents felt pain in the neck (88.32%), lower back (75.00%), mid back (73.33%) and upper back (72.50%) while working on computer/laptop. Overall bodily fatigue or tiredness, shoulder or back pain/stiffness and headache during or after working on the computer were the major symptoms as reported by respondents
Weed flora of aerobic rice and their effect on growth, yield and nutrient uptake by rice Oryza sativa in the coastal region of Karaikal of Puducherry, India
Authors: Pavithra M. , Poonguzhalan R.
Published: April 2018

A field experiment was conducted at farm lands of Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal to know the weed floristic composition and their effect on growth, yield and nutrient uptake by aerobic rice (Oryza sativa). The results revealed that totally 29 species of weeds from 22 genera belonging to 17 families were noticed. Among them, four were grasses, six were sedges, and nineteen were broad leaved weeds. Of this 29 species, four were perennials, and the rest were annuals. During initial stages (30 DAS), sedges dominated (38.3%) whereas at later stages (60 DAS) broad leaved weeds dominated the aerobic rice fields (42.5%). Grasses were found to be comparatively less dominant at both the stages. Echinochloa colona Link. (28.1%) followed by E. cruss-galli (L.) Beauv. (6.1%) among the grasses; Cyperus difformis L. (19.8%) followed by C. iria L (9.9%) among the sedges and Ludwigia abyssinica (28.0%) among the broad leaved weeds, were the predominant weed species in aerobic rice cultivation. Weeds, when left unchecked, competed with rice for all resources like nutrients, space, light and soil moisture. The unweeded control recorded the maximum nutrient depletion by weeds (76.6, 6.4 and 106.8 Kg of N, P andK ha-1 ). Due to severe competition, weeds suppressed the growth of rice which resulted in lower growth and yield attributes leading to lower grain (333 kg ha-1 ) and straw yields (1903 kg ha-1 ).
Mango malformation: A fungal disease, physiological disorder or malady of stress
Authors: Kaur Avneet , Kaur Nirmaljit
Published: April 2018

Mango (Mangifera indica L.) is one of the important commercial crops occupying a prominent place among various fruit crops. Mango malformation is a crucial malady in mango production leading to heavy economic loss. Malformation occurs in vegetative as well as floral tissue, later being virulent leading to loss of entire crop. Fusarium moniliforme is suggested as dominant causal agent of the disease although association of ‘stress ethylene’ with disease occurrence has also been studied. Fungal pathogens responsible for the malady are known to elevate the level of ‘stress ethylene’ in malformed plants. Various reports have been put forward to explain the etiology and control measures of the disease but nature and management of the disease is still a mystery. Hence, the present review aims at offering information regarding aspects of development and management of mango malformation.

Published: April 2018

Thirty genotypes of forage sorghum were studied for generating information on nature and magnitude of genetic variability and diversity for designing breeding programme. The experiment was conducted in randomized complete block design in three replications. The data were recorded on days to 50% flowering, plant height, leaf breadth, leaf length, leaf area, stem girth, leaves per plant, leaf stem ratio, total soluble solids, protein content and green fodder yield. Analysis of variance revealed a substantial amount of variability among the genotypes for all the characters under study, indicated a wide spectrum of variability among the genotypes. Highest estimates of the phenotypic coefficient of variation and genotypic coefficient of variation were observed for plant height, leaf breadth, leaves per plant, leaf stem ratio and green fodder yield. High heritability coupled with high genetic advance was observed for plant height, leaf area, stem girth, leaves per plant, leaf stem ratio and green fodder yield. Based on D2 – Statistics, 30 genotypes were grouped into six clusters. The highest inter-cluster distance was observed between cluster III and VI followed by IV and VI, indicating genotypes included in these clusters had wide genetic diversity. Genetic divergence and cluster mean indicates maximum heterosis and good recombinants may be achieved in crosses between genotypes of clusters III, IV and VI in varietal improvement programme. Thus, crossing between genetically diverse genotypes of cluster III with genotypes CSV 15, PC 1001, SPV 462, PC 3, SSV 84, PC 8 and cluster VI with genotype HJ 513 are expected to exhibit high heterosis and good recombinants with desired traits.

Effect of zinc and iron interaction on their distribution was examined in two wheat genotypes (UP262 and UP2628) under foliar application of 0, 0.25 and 0.50% ZnSO4 solution tagged with 925 KBq of Zn65 pot-1 for Zn and 0, 0.5 and 1.0% FeSO4 solution tagged with 925 KBq of Fe59 pot-1 for Fe at 30, 60 and 90 days after planting. Maximum grain yield of UP2628 (2.7 g pot-1 ) was recorded at 0.5%ZnSO4+0%FeSO4 while that of UP262 (2.63 g pot-1 ) was recorded at 0.5%ZnSO4+1.0%FeSO4. The highest straw yield of UP2628 (2.75 g pot-1 ) was noted at 0.5% ZnSO4+1.0%FeSO4 while that of UP262 (2.91 g pot-1 ) with 0.5%ZnSO4+0.5%FeSO4. Application of 0.5% and 1.0% FeSO4 reduced the accumulation of 65Zn in all parts of both the varieties. Regarding the 59Fe accumulation, it was found to be decreased with the increased application of ZnSO4 solution from 0.25% and 0.5% as compared to without application of Zn. On comparing translocation efficiencies of both the varieties, UP2628 showed better translocation thus accumulated higher zinc and iron. Therefore, variety UP2628 can be used further for crop improvement programme.

Authors: Kamboj Gaurav , Kumar Pradeep , Singh Devi
Published: April 2018

A study was conducted during two crop season (Kharif, 2011-12 and 2012-13) for estimating the genetic parameters by involving 10 parents and their 45 F1s in rice crop. The estimates of h2 (overall dominance effects) were positive and significant for days to 50 % flowering (9.11), days to maturity (0.24), plant height (2.95), panicle length1(39), productive tillers per plant (3.22), branches per panicle (5.61), flag leaf area (5.50), 1000-grain weight (0.27), biological yield (7.35) and amylose content (1.03) which indicated dominance of genetic components in F1s crosses. The theoretical value (0.25) of (H2/4H1) for all the traits except kernel length and amylose content indicated the asymmetrical distribution of positive and negative genes in the parents. The proportion of dominant and recessive alleles for panicle length, productive tillers, branches per panicle, 1000 grain weight, biological yield, kernel length and L/B ratio reflected more dominant alleles, whereas for days to 50 % flowering, days to maturity, plant height, grains per panicle, flag leaf area, grain yield, harvest index, kernel breadth, kernel length after cooking, elongation ratio, amylose content and hulling %, reflected more recessive alleles in the parents. The estimates of specific combining ability (SCA) effects revealed that the cross Vallabh Basmati 21 x Pusa 1121 could be an excellent candidate for improving grain yield (1.52**), harvest index (1.86**) and flag leaf area (6.20**) whereas Pusa 1121 x CSR 10 is excellent candidate for panicle length (0.89**) and amylose content (1.54**). The characters showing more than 60 % narrow sense heritability along with positive and significant correlation with each other and also with grain yield could be rewarding for further improvement of yield and quality in rice. Therefore, these parental lines can be used as donors in future by following bi-parental mating and the diallel selective mating system could be the best breeding method in an early segregating generation for improvement in these traits in rice crop.

This study describes the length-weight relation (LWR) of small indigenous fish Pethia ticto from Gomti River, Aamghat, Haliyapur, Sultanpur district 260 29N and 810 44E, 751m (msl) Uttar Pradesh, India. A total of 306 specimens were caught by random sampling method using traditional fishing gear as gillnet, cast net and dragnet of various mesh sizes from June 2016 to May 2017, once in a month. Total Length (mm) was measured from anteriormost part of the snout to the posterior-most part of the caudal fin and body weight (g) were taken by digital electronic balance. The analysis of data shows that the allometric coefficient is close to isometric value (3.0). Allometric growth indicates a more rotund population of fish when the values of growth coefficient are higher than 3.0 (b>3). If the value of growth coefficient is less than 3.0, the population of fish is known to be less rotund. Isometric growth indicates that the shape of fish does not change as it grows (b=3). The coefficient of determination (R2 ) was also found significant (=0.97). Fulton’s condition factor further supports the results obtained ranged from 1.041 to 1.660 shows the degree of well being of a fish. This study is helpful in providing relevant information in the assessment of stock and estimation of the fish condition about its environment

Published: April 2018

An experiment was conducted to evaluate the effect of different artificial diets on the adult’s biological attributes of sugarcane stalk borer (Chilo auricilius Dudgeon) and their costs. Considering the mean values of first and second generation the maximum adult emergence (80.66 and 79.25), longer adult longevity (4.29 and 4.28), highest fecundity (233.45 and 225.98) and viability of egg (216.25 and 208.74) was recorded on diets A and C. Also the sex-ratio on diets A (M:F::1:1.16) and C (M:F::1:1) favoured the emergence of more number of females thanmales during development. On the basis of the economics also the artificial diets D, C and A (Rs. 48.62, Rs. 48.32, Rs. 103.43, respectively) were found relatively cheaper than the natural food (Rs 166.67). Thus, the overall performance of C. auricilius on diets A and C was found comparatively better than the other diets examined. Therefore, it can be used as an alternate diet other than natural diet E (sugarcane) for the mass rearing of C. auricilius in the laboratory.

Authors: Begum Salma , Nath P. S.
Published: April 2018

The anthracnose of chilli caused by Colletotrichum capsici is a widespread problem limiting the profitable cultivation and seed production of chilli throughout the major chilli growing regions of India. Four isolates (SCC1, SCC2, SCC3 and SCC4) of C. capsici were collected from different chilli growing areas of West Bengal. An experiment on efficacy of four botanical oils viz., Garlic (Allium sativum), Neem (Azadirachta indica), Polyalthia (Polyalthia longifolia) and Citronella(Cymbopogon nardus) at concentrations of 0.05%, 0.1% and 0.2% and two isolates each of three biocontrol agents (Trichoderma harzianum, T. viride and Pseudomonas flourescens) were carried out against these isolates of C. capsici in vitro. The result revealed significant (5% level of significance) antifungal activities of these botanicals and biocontrol agents. Garlic gave cent per cent inhibition of mycelial growth of all the four isolates of C. capsici at all the concentrations tested. However, neem showed cent percent inhibition of mycelial growth of C. capsici at 0.1%. Citronella was least effective among the botanical oils. Among the biocontrol agents tested T. harzianum isolate Th-2 was found most effective giving 77.78%, 100%, 83.33 % and 88.89% inhibition on the mycelial growth of SCC1, SCC2, SCC3 and SCC4 respectively followed by T. harzianum isolate Th-1 inhibiting 74.00%, 78.9% 81.7% and 80.90% of the mycelial growth of SCC1, SCC2, SCC3 and SCC4 respectively. P. fluorescens was least effective. Thus, garlic, neem, polyalthia, T. harzianumand T. viride can be utilized for management of anthracnose of chilli.

Published: April 2018

Among the various treatments evaluated for their bio-efficacy against mustard aphid on Indian mustard during 2011-12 and 2012-13 at CCS Haryana Agricultural University, Hisar, the spray of Dimethoate 30 EC @ 1 ml/l followed by Verticillium lecanii @ 108 CS/ml was proved to be the best treatment with pooled mean aphid population of 4.5, 3.25 and 1.65 aphids/plant as against 22.0, 24.0 and 26.0 aphids/plant in the control after 3, 7 and 10 days of treatment, respectively. The pooled mean seed yield was also maximum (1485.0 kg/ha) in this treatment as compared to control (1305.0 kg/ha).The treatment was found on par with spray of dimethoate @ 1 ml/l followed by Coccinella septempunctata @ 5,000 beetles/ha with pooled mean aphid population of 5.0, 4.0 and 2.0 aphids/plant after 3, 7 and 10 days of treatment, respectively and pooled mean seed yield of (1470.0 kg/ha). But the cost benefit ratio was maximum (7.25) in treatment dimethoate followed by C. septempunctata and NSKE @ 5% followed by C. septempunctata @ 5,000 beetles/ha (6.68). Thus, entomopathogenic fungi like V. lecanii or NSKE along with release of C. septempunctata can be used as alternative measure to manage mustard aphid instead of solely relying on insecticides.

Published: April 2018

In the present study, the genetic diversity and inter-relationships among 12 varieties of pea were analyzed by using RAPD markers. A total of 118 bands were generated with 20 RAPD primers, of which 107 bands were polymorphic (90.81%). The PIC value ranged from 0.602-0.863 with an average of 0.754. High level of polymorphism and low genetic similarity within pea varieties suggested that they have a high level of genetic diversity. Unique RAPD fragments (700bp-1500bp) were also observed in five varieties i.e., AP-01, Aparna, Uttra, Rachna and Rachna-1D. In the dendrogram, 12 varieties were broadly grouped into 2 main clusters consisting of 5 (Cluster-I) and 4 (Cluster-II) varieties, respectively, while other three varieties i.e., KPMR-522, Aparna and AP-03 were out of group. In cluster-I, Ambika and AP-01 and Rachna and Vikas showed 62% and 58% similarities whereas, HUDP-15 grouped with 56% similarities with rest two varieties. In cluster II, Uttara and Prakash showed maximum similarity (65%) whereas, Rachna1-D showed (58%) similarities with them. KPMR-400 showed 52% similarity in this group. KPMR-400, Aparna and AP-03 were more diverse in comparison to others. A two-dimensional plot generated from principal co-ordinate analysis of RAPD data also supported the clustering pattern of dendrogram. This study indicated the presence of high genetic diversity among pea varieties, which could be used for developing core collections of pea germplasm for breeding and germplasm management purposes.

Published: April 2018

Intervening cropping period perhaps the most ignored period, which could be exploited for cultivating the intervening crops which further add to the soil, crop and water productivity and finally livelihood of the farmers of the region. The present investigation was carried out after rice- 2014, to monitor the residual effect of different tillage (wheat), establishment methods and tillage (rice) on the fluctuating behaviour of the soil moisture during intervening period. Our findings suggested that CTW-DSRZT (conventionally tilled wheat and zero till direct seeded rice) plots conserved more moisture than ZTW-DSRZT (zero till wheat and zero till direct seeded rice) plots an exception of CTWDSRCT plots which were almost equally effective in conserving the soil moisture. On an average, soil matric tension (SMT) was reported to be 36% higher in CTWDSRZT than CTWDSRP plots at 10cm soil surface. Further, ZTW-DSRZT plots on an average dried 8% faster than ZTW-DSRP plots. At 20cm, DSRZT plots dried 3% faster than its allied plots while at 30cm depth, in DSRP plots, SMT values increased 12% and 11% higher under CTW block and ZTW blocks, respectively than its allied plots. SMT readings in all the ZTW plots on an average increased at much more faster rates (24%) than CTW plots. The ZT plots had 1.4% higher water depths than the CT plots. Evaporation losses pragmatic to be higher (17.2% and 7.3%) in ZTW-DSRZT plots as compared to the ZTW-DSRCT and CTW-DSRCT plots which might improve declining crops and water productivity in the region.

Published: April 2018

The aim of this study was to evaluate the effect of letrozole (a non-steroidal aromatase inhibitor) on masculinization of Siamese fighting fish (Betta splendens). Different doses of letrozole 50, 100, 150 and 200 ppm (mg/kg feed) were incorporated into diet and fed for periods of 30, 40 or 50 days. Immersion treatment of letrozole at selected doses (250, 500, 750 and 1,000?g/l) for 3 h each on third, fifth and eighth day-post-hatching (dph) (Trial 1) and fourth, sixth and eighth dph (Trial 2) was given.The oral administration of letrozole for 30, 40 or 50 days did not have any significant effect on the sex ratio of B. splendens. The immersion treatment of letrozole induced 100% masculinization at 500 and 1000?g/l in trial 1, while it yielded only 66.66 and 90% male population at 500 and 1000 ?g/l in Trial 2. The dietary administration of letrozole for 30 and 50 days caused tail deformities and/or rudimentary and absence of dorsal fin. The progeny testing of males from letrozole treated (both oral and immersion) groups indicate that the sex ratio of progenies of each of the males tested did not differ significantly from that of control, indicating that all those males carried XY genotype. Letrozole treatments suppressed ovarian development (atretic oocytes were common). However, the testicular development was unaffected. The study revealed that immersion treatment of letrozole was more effective in inducing masculinization of B. splendens than the oral administration of letrozole.
A review on plant growth promoting rhizobacteria acting as bioinoculants and their biological approach towards the production of sustainable agriculture
Authors: Nehra Vibha , Choudhary Madhu
Published: April 2018

Plant growth promoting rhizobacteria are the soil bacteria inhabiting around/on the root surface and are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory chemicals in the vicinity of rhizosphere. There has been much research interest in PGPB and there is now an increasing number of PGPB being commercialized for various crops. Today a lot of efforts have been made for searching and investigating the PGPB and their mode of action, so that they can be exploited commercially as biofertilizers. Because of the various challenges faced in screening, formulation, and application, PGPB have yet to fulfill their promise and potential as commercial inoculants. Recent progress in our understanding of their diversity, colonization ability, mechanisms of action, formulation, and application should facilitate their development as reliablecomponents in the management of sustainable agricultural systems. Several reviews have discussed specific aspects of PGPB as bioinoculants. We have tried to critically evaluate the current status of bacterial inoculants for contemporary agriculture in developed and developing countries. This review focuses on some important information regarding the biofertilizing potential of some important group of microbes, their formulations, their application for the development of sustainable technology, scope of improvement by genetic engineering, steps to be undertaken for their commercialization and their future prospects.

The present study on biochemical basis of resistance against Leucinodes orbonalis infestation was conducted during the year 2011-2012. The results revealed that highest chlorophyll-‘a’- content of 0.497 mg/gfw was recorded in the susceptible genotype SHB-1.The lowest amount of 0.319 and 0.381 mg/gfw was observed in the resistant genotypes Brinjal-85 and Local long respectively, which were significantly different from other evaluated genotypes. The chlorophyll ‘a’content was positively correlated with the brinjal shoot and fruit borer infestation. Thehighest chlorophyll -‘b’- content of 0.442 mg/gfw was recorded at 70 DAT (days after transplanting). The amount of chlorophyll -‘b’- varied significantly among the genotypes at different ages and decreased with the age of crop. The average highest amount of chlorophyll -‘b’- was estimated in the genotype SBH-1 which was significantly at par with hybrid SBH-2. The lowest chlorophyll -‘b’- content was recorded at 40 DAT in the genotype Brinjal-85 followed by Local Long. The lowest amount of total chlorophyll was estimated in the resistant variety as compared to susceptible therefore exhibiting lowest level of infestation.
