Authors: Kasinath B L , Ganeshamurthy A N , Nagegowda N S 
Published: August 2023

A field experiment was conducted on magnesium nutrition in tomato hybrid Arka Ananya at ICAR-IIHR, Bengaluru, for two years. Graded application of magnesium produced significant difference in fruit yield in tomato among treatments. The yield increased upto 50kg Mg ha-1 application, and decreased beyond this dose. Yield parameters like number of fruits per plant and fruit weight recorded results similar as that of yield. Growth parameters like number of branches and plant-height followed a similar trend. Growth and yield parameters were found to be well correlated with yield. Treatment T3 (50kg Mg ha-1) recorded significantly higher plant height, number of branches, fruit number, fruit weight and fruit yield over the Control, T1, where no magnesium was applied. Yield increase of 29% can be achieved with magnesium application (50kg Mg ha-1) in tomato during winter season.

Published: August 2023

Influence of plant growth regulator sprays on corm production and post-harvest life of two gladiolus cultivars, Darshan and Dhiraj, was investigated for two consecutive years, 2008-09 and 2009-10. Growth regulators, viz., gibberellic acid (100 and 150ppm), tri-iodo benzoic acid (TIBA) (50 and 100ppm), 2-chloro, 4-pyridyl phenyl urea (CPPU) (2.5 and 5ppm) and brassinosteroid (BR) (5 and 10ppm) were sprayed at the 3rd and 6thleaf stage. Cv. Darshan recorded maximum number of large cormels per plant and cormel weight, while, cv. Dhiraj recorded maximum number of small cormels per plant in treatments of pre-harvest foliar sprays with plant growth regulators. Foliar sprays of BR (10ppm) and GA3 (150ppm) significantly increased number of corms produced per plant, corm size, corm weight, and propagation coefficient. Number of large cormels and total number of cormels per plant were significantly higher in BR (10ppm), followed by TIBA (100ppm). BR (10ppm) and TIBA (100ppm) produced maximum number of small cormels per plant. Weight of cormels per plant was maximum in BR (10ppm) and GA3 (150ppm). Post-harvest studies revealed that cv. Darshan recorded maximum diameter of second fully-opened floret and higher vase-life than cv. Dhiraj with pre-harvest foliar spray of plant growth regulators. Pre-harvest foliar spray of GA3 (150ppm), BR (10ppm) and CPPU (5ppm) induced earliest first-floret opening and recorded maximum value for number-of-floretsopen- at-a-time per spike, diameter of second fully-opened floret, and vase-life. Foliar spray of BR (10ppm) and GA3 (150ppm) at 3rd and 6th leaf stage can be recommended for large-scale multiplication of quality planting material and longer vase-life of flower spikes, respectively, in gladiolus.

Authors: Nongmaithem Nabakishor 
Published: August 2023

Fruits of guava cultivar 'Allahabad Safeda' at mature yellowish-green stage were collected from Allahabad fruit market. Nine post-harvest fungal pathogens were isolated from these fruits. Of these, two isolates with highest incidence, namely, Pestalosia psidii (fruit canker causing pathogen) and Gloeosporium psidii(anthracnose causing pathogen) were used in the study. Fruits inoculated with the pathogens and Control (a lot of fruits with no treatment) were stored at ambient temperature. The fruits were analyzed for various quality attributes at different storage intervals for upto 15 days. Data revealed that fruits in all the treatments showed a lower fruit-weight loss compared to the untreated fruits. TSS, acidity (%) and ascorbic acid content (mg/100g) were also found to decrease in relation to the Control at 5, 10 or 15 days of storage. The least PLW was recorded in Gloeosporium psidii-treated fruits, followed by those treated with Pestalosia psidii. But for the bio-chemical changes (also due to post-harvest fungi) Gloeosporium psidii-treated fruits had higher TSS, acidity (%) and ascorbic acid content (mg/100g) than Pestalosia psidii-treated fruits.

Published: August 2023

A study was under taken on fruit and seed morphology, seed drying, seed germination and storage behavior in Baccaurea courtallensis, as, this plant is propagated mainly through seeds. Its fruit is a berry consisting of an outer, semi-hard but fleshy rind 2-3 mm thick. The cavity inside the rind is normally occupied by a single, arillate seed, but, two seeds are also seen occasionally. Fresh rind was found to be rich in antioxidants, with 237mg total phenols and 93mg flavonoids per 100 gram fresh weight, but was poor in Vitamin C. A thick, fleshy endosperm is surrounded by the inner seed-coat. The endosperm surrounds the embryo consisting of two papery-thin cotyledons and a minute embryonic axis. Germination was highest (96.7%) when seeds were sown immediately after extraction, with moisture content of about 50%. Reduction in moisture to below 34% showed a drastic decrease in germination. Dried seeds took longer to germinate than did the fresh ones. Seeds with 21% moisture recorded about 60% germination whereas, seeds with 10.2% or 8% moisture failed to germinate, indicating a recalcitrant seed. Temperature in the range of 25-30°C was found to be optimum. Of the two media tested for raising the seedlings, cocopeat medium was superior as, it induced faster growth of the seedlings. Seedling root and shoot were considerably longer, with higher seedling survival rate in cocopeat than in the soil-mix medium. Seedling establishment was poor when planted out of their natural habitat.

Published: August 2023

The present study purports to assess the effect of Agrobacterium infection time, co-cultivation and cell density on in vitro response in hypocotyl explants of eggplant (brinjal) cv. Manjarigota. Agrobacterium(OD600 0.3-0.5) infection for 10-15 minutes (24.44±2.34%) was found to be optimum, while, higher or lower infection-time resulted in reduced callus initiation, shoot regeneration and explant survival. Explants with no (only Agrobacterium infection) or short (1 day) co-cultivation, showed reduced callus-initiation response and turned yellow, with no regeneration. Callus-initiation response increased from Day 1 (96.66±03.33%), and reached a maximum on Day 2 and Day 3 (100±00.00%). It decreased on further increase in co-cultivation time. Explants co-cultivated for three days showed highest regeneration response (30.00±02.96%) which thereafter reduced with further increase in co-cultivation time. Explants infected with Agrobacterium culture at 0.05 OD600 showed hardly any regeneration, and turned yellow and necrotic on the selection medium. Highest regeneration response (28.33±02.33%) was obtained in explants infected with 0.1 OD600 culture, and this gradually reduced as celldensity increased (upto 1.0 OD600), becoming zero in explants treated with cultures at 1.5 OD600 or above. Agrobacterium overgrowth was noticed on explants infected with cultures of 0.5 OD600 and above. Exposure of hypocotyl explants to higher cell-density, longer infection-time and prolonged co-cultivation regime resulted in severe necrosis of explants; time taken for development of Agrobacterium overgrowth was less with increase in the level of these factors. Regenerated shoots were healthy, green, elongated and showed root induction on culture medium containing Kanamycin.

Published: August 2023

Decline in general plant-health and fruit production in mandarin influenced by abiotic and biotic factors is a major threat to cultivars grown in Darjeeling and Sikkim hills. Fusarium root rot, caused by F. oxysporum, is one of the most serious diseases afflicted during early plant growth stage in Citrus. To address this, seven PGPR isolates - Pseudomonas poae (RMK03), Bacillus stratosphericus (RHS/CL-01), Ochrobactrum anthropi, Paenibacillus lentimorbus, Bacillus pumilus, Bacillus megaterium and Bacillus amyloliquefaciens were isolated from the rhizosphere of Citrus reticulata, C. limonia and Camellia sinensis, and used for evaluating their effect on growth of mandarin seedlings. Pseudomonas poae showed in vitro antagonism to Fusarium oxysporum. Better growth enhancement was noticed with P. poae, B. stratosphericus, O. anthropi and B. pumilus. Enhanced activity of chlorophyll, total protein, phenol, four major defense enzymeschitinase, β-1, 3-glucanase, peroxidase and phenyalanine ammonia lyase was observed upon application of PGPR. P. poae also suppressed root rot caused by Fusarium oxysporum. Use of PGPR, which promote growth besides reducing disease severity to some extent, may lead to use of eco-friendly approaches for controlling plant diseases.

Published: August 2023

A simple and rapid protocol for somatic embryogenesis in banana cv. Nendran (AAB) using immature male flowers (IMF) has been developed. The IMF produced palewhite to yellow, globular embryogenic callus on MS medium supplemented with BA (0.05 - 0.50mgL-1) and picloram (0.50 - 2.00mgL-1) with explant response of to 30 per cent. Addition of ascorbic acid (20mgL-1) and Gelrite© (0.45 per cent) to callus induction medium reduced interference from phenolic exudation. Embryogenesis was induced (33.3 to 60 per cent) on semisolid (0.30 per cent Gelrite©) MS medium supplemented with BA 2mgL-1 + IAA 0.5mgL-1. The somatic embryos showed 60-80 per cent germination on half- strength semisolid MS medium with BA 2mgL-1 + IAA 0.5mgL-1. Transfer of germinated embryos to semisolid MS medium supplemented with BA 2mgL-1 + NAA 1mgL-1under 14 h light /8h dark photoperiod resulted in hundred percent conversion to plantlets. This protocol takes merely 6 months for producing plantlets from immature flower buds through somatic embryogenesis, without any intermediate liquid cultures.
Effect of Cane Regulation and GA3 Spray on Berry Thinning in 'Thompson Seedless' Grape (Vitis vinifera L.)
Authors: Shikhamany S D , Borade Swapnil V , Jeughale Sanjay K , Patil Suryakant Y 
Published: August 2023

A field trial was conducted during 2013-14 and 2014-15 fruiting seasons in growers' vineyards around Nashik, Maharashtra, India to improve efficacy of GA3 sprays in berrythinning. As smaller clusters have fewer berries, cluster compactness derived at by number of berries per unit length (cm) of rachis, and, berry-diameter were considered as a measure of berry-thinning. As GA3 effect in berry-thinning is stage-specific, canes uniformly thick in a vine only were retained to achieve uniformity in flowering, by inducing uniform bud-break. Cane regulation did not result in uniformity in bud-break or flowering. Blanket spray of GA3 thrice @ 20g a.i./ha, each coupled with either removal of non-uniform canes or retention of all the canes could effectively reduce cluster compactness by reducing number of berries per cluster, without increasing total length of the rachis/cluster or berry diameter. Vine yield and quality in terms of total soluble solids and acid content were not affected by the treatments. Considering cluster-compactness, yield and ease of cultural operations, retention of all the canes in a vine, coupled with three blanket sprays each of GA3 @ 20g a.i/ha, on alternate days commencing from initiation of the bloom, is recommended for 'Thompson Seedless'.

An experiment was undertaken to develop an improved in vitro regeneration protocol in gerbera. Murashige and Skoog (MS) medium was supplemented with various growth regulators at different concentrations for callus induction and organogenesis. Newly emerging leaves of Gerbera cv. Rosalin were used as explants. Experimental results showed that maximum rate (74.07%) of formation of callus with good growth was recorded on MS medium supplemented with 2.0mgL-1 2,4-D + BAP 0.5mgL-1. Best shoot regeneration (57.8 %) with maximum shoot number (12.0) was achieved on with BAP 2.0mgL-1 + NAA 0.5mgL-1 fortified MS medium. Maximum (66.7 %) and earliest (12.3 days) root formation in shoots was recorded on IBA 3.0mgL-1is 1/2MS media. Survival rate of regenerated plantlets was maximum (73.33 %) in the potting mixture containing garden soil, sand and vermicompost (1:1:1).

A field experiment was conducted at Bengaluru during 2015 to study the effect of fertigation on performance of hybrid chilli (Capsicum annuum L.). The trial included nine treatments comprising varying rates and sources of fertilizers, tested with or without mulching. Application of recommended dose of fertilizer (180:120:180 kg NPK/ha) through fertigation using water-soluble fertilizers resulted in higher values for plant height (104.27 cm), number of branches per plant (16.71), leaf area per plant (89.44 dm2), dry matter per plant (185.49 g), number of fruits per plant (142.7), fruit length (11.13 cm), fruit girth (4.75 cm), fruit weight (1.29 g), yield per plant (184.11 g) and fruit yield (5.03 t/ha) which remained on par with same amount of fertilizer applied using conventional means along with polyethylene mulching. In general, treatments that received fertilizers through fertigation took less number of days to flowering over conventional soil-application of fertilizers. All fertigation treatments recorded higher dry-chilli fruit yield over the conventional soil-application of fertilizers, to a tune of 27.87% to 52.4% over the control.

Published: August 2023

Bacterial wilt disease, caused by Ralstonia solanacearum, is one of the major concerns for marigold cultivation in Andaman Islands. Cross-infectivity potential of the bacterial wilt pathogen, isolated from marigold, was tested in other common vegetable-hosts of the Island. Pathogen identity was confirmed by morphological identification and Biolog based phenotypic fingerprinting. Cross-infectivity tests revealed tomato to be the most susceptible among the three solanaceous hosts tested. Highest wilt incidence was observed in tomato and marigold (100%) plants, followed by 55.6% in brinjal and 22.3% in chilli, upon artificial soil inoculation. Our study enlightens pathogenic potential of the bacterial wilt pathogen in important vegetable crops of Andaman Islands and can help formulate suitable management practices for successful management of the pathogen.

Authors: Varalakshmi B , Pitchaimuthu M , Rao E Sreenivas 
Published: August 2023

The present investigation was conducted to determine the variability, heritability, genetic advance and correlation of fruit yield and ten different yield contributing characters in bottle gourd. Wide range of variation was observed for most of the characters like fruit yield/vine, fruit number/vine, fruit weight, fruit yield/ha and node number for first female flower appearance. Phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the traits studied, indicating environmental influence on expression of these characters. However, high heritability (broad sense) along with high genetic advance was recorded by vinelength, branch number, fruit length, fruit width, fruit yield/vine and yield/ha indicating the presence of additive gene effects, hence selection can be employed for the improvement of these parameters. Fruit yield/ ha was significantly and positively associated with fruit number/vine and fruit yield/vine both at genotypic as well as phenotypic levels. Fruit number had maximum direct effect (0.812) on fruit yield/ha followed by fruit weight (0.407), fruit length (0.339), fruit width (0.310), fruit yield/vine (0.249), days taken for first female flower appearance (0.224) and vine length (0.173). Therefore for the yield improvement in bottle gourd, emphasismay be given for indirect selection through fruit parameters like fruit weight, fruit length, fruit number and fruit yield/vine.

Published: August 2023

Being a tree crop of commercial importance, the productive performance of cashew is greatly influenced by how best its canopy is architectured for harnessing maximum benefits in terms of yield. The initial training is crucial for the development of photosynthetically efficient canopy in cashew as in other perennial fruit trees. Pruning of dead wood and crisscross branches can alone increase the yield by 30-40 per cent. The dwarf rootstocks also play a role in manipulating the canopy in cashew, wherein, canopy containment and yield were influenced by such rootstocks. By resorting to soil application of growth retardants like paclobutrazol, cashew canopy could be successfully contained to suit high density planting system. The studies on planting geometry has indicated the advantage of high density planting in enhancing profitability of cashew orchards in the initial years of plantation. The advantages of rejuvenation as well as top working techniques are also discussed in this aper.

Published: August 2023

Mountain sweet thorn (Flacourtia montana J. Grah) is an indigenous underutilized fruit of the Western Ghats and other regions of peninsular India. It is a close relative of Governor’s plum. It is a bushy shrub or small tree with spiny trunks and branches which may grow up to 2.5 m in height. The fruits are bright dark red 1-2 cm in diameter, sweet edible, and have the potential for processing into jams and jellies. The presence of thorn is one of the major hurdles for the commercialization of this crop. Thus, seeds of the thorny plants of the Mountain sweet thorn were collected from different locations, and seedlings were planted to identify the suitable line. The plant height ranged from 425 cm (accession 0208) to 710 cm (accession​ ​0202). The plant girth ranged from 34.5 cm to 82 cm. The growth data revealed that all​ ​the accessions are vigorous, fast-growing, and have various levels of thorniness. All the​ ​accessions were found to be spreading type. Significant variability was recorded for leaf​ ​characteristics among the accessions studied. Three major clusters were observed in​ ​cluster analysis for morphological and fruiting characters consisting of 1, 8, and 9 accessions,​ ​respectively. The number of fruits ranged from 0 to 4008. The highest yield (9.46 kg/plant)​ ​was obtained in accession - 0106 followed by accession- 0201 (7.83 kg). The average​ ​fruit weight ranged from 1.51 g to 3.94 g. The highest fruit weight (3.94g) was also recorded​ ​in 0106 followed by 2.84 (0102). The total soluble solids ranged from 10 0 Brix to 15.1 0​ ​Brix. Overall, accession 0201 was found better than others with respect to yield, regular​ ​bearing, and less thorniness.
