Thirty six genetically diversified clusterbaan [Cyamopsis tetragono loba (Linn.) Taub.) were studied for 10 matric traits during monsoon 1976 for the correlations, path cooffi- cient analysis and genetic diversity. Soed yield/plant showed significant positive corre- lation with number of pods/plant, 100 seed weight, plant height, numder of branches/ plant and number of clusters/plant. Similarly path coefficient analysis indicated the importance of number of pods/plant, 100 seed weight, which had maximum direct effect on sced yield. However, plant haight, number of branches/plant and number of clusters/ plant affected seed yield via pods/plant. Mahalanobis D' statistics was used to assess the genetic diversity among the genotypes which could be grouped in 5 clusters. The distribution of genotypas in different clusters was not according to their places of origin.

The results of the field experiment revealed that sesame was sensitive to low tempe- rature, but the variety B-67 was less affected due to low temperature as observed from its growth duration. It took 8 to 16 days less time to mature and produced 1.7 q/ha more yield than that of improved local. Growth continued for a long duration when the crop was sown in October (110-126 days) and this was followed by February and Sep- tember sown crop (90-108 days). Crop grown in Kharif season matured early (80-90 days). Tall plants were found in June sown crop of B-67 and April sown crop of Improved local. Maximum yield (17 q ha) was recorded in March sown crop followed by February and August sown crop. The October sown crop produced lowest yield (4.5 a/ha). The yield obtained from the crops sown in other months ranged from 7.4 g/he to 9.4 q/ha. The oil content ranged from 43.5% in wet months to 46.5% in ether months. The high yield was associated with high number of branches and pods per plant with large number of bold seeds. 8-67 proved to be superior in this zone.

The nature and magnitude of genetic variances involved in the inheritance of fruit yield and its components were investigated in a 8 parant diallel cross without reciprocals in chilli (Capsicum annuum L). The graphic. component and combining ability analyses revealed the preponderance of nonadditive genetic varia tion in the inheritance of all the traits Wr-intercepts revealed the partial domi- nance for fruit length, fruits/plant and fruit yield/plant. The dominance components (H, 2H,) p'ayed significant role in the inheritance of all the attributes. Speci- fic combining ability variances were higher than general combining ability for all the traits, as also revealed by average degree of dominance. Heritability estimates were quite low for all the traits. Recurrent selection by way of intermating the most desirabla segregates alternatively with-selection may be employed in advanced generations.

Chemical control of major pest complex of radish grown for its edible root was studied over three seasons at Bangalore. Results revealed that insecticide sprays were not necessary when the crop is either attacked by flea beetles alone or by flea beetles and lepidopterous pests at late crop growth stages, since it did not affect the marketable yield. However, there was a need to resort to insecticide sprays when the crop was attacked by both flea beetles and mustard sawfly. Signi- ficant reduction of both the posts was observed after application of 0.07% endosultan, 0.05% monocrotophos, 0.07% phosalone, 0.05% methyl parathion, 0.01% fenvalerate and 0.0014% deltamethrin, with a consequent increase in yield.

An experiment was conducted to study the effect of sulphur fertilisation on nutrition and yield of groundnut. The results indicated that the basal application of sulphur in the from of sulphur dust (22 kg/ha) Increased the dry matter and pod yield significantly. Higher Hl and higher contribution by pod to the total dry matter production indicated the greater efficiency in translocation of assimilates from source to sink. The increase in pod yield was mostly due to the increase in dry matter production (r=0.895) rather than the Ht (r=0.805) Sulphur appli cation had increased the carbohydrate, protein and oil contents in kernel. The 100- kernel weight and shailing percentage were also high in sulphur dust treated plants

Wide variations are seen in the occurrence of rainfall and distribution in Coimbatore district. As such arithmetic mean may not represent the average rainfall. so Thiessen-weighted average and Isohyetal average of rainfall were worked out.. The arithmetic mean (826.70 mm) was the lowest and the Thiessen weighted average value was increased by about 100 mm. The isohyetal average showed a very high value (1348.05 mm): These variations were due to the non-uniformity in the dis- tribution of rain gauges and also because of steep precipitation gradients. Isobyetal mean which seems to be more representative, should be utilised for hydrological analysis such as surface water, recharge of ground water etc.

A field experiment was conducted during the rainy seasons of 1984 and 1985 to study the effect of intercrops on nodulations, growth, nitrogen content and pod- yield of groundnut (Arachis hypogaea L) Tall growing cereal intercrops viz. pearl. millet and corn significantly affected the nodulation, plant growth and n trogen cont- ent of plants at pod filling stage (75 days.) while no such effects were, observed during the initial stages of crop growth. The above traits were unaffected when groundnut was grown in combination with sesamum, sunflower, soyabean and cowpea. The pod yield was also significantly reduced under cereal intercropping as compared to sole crop of groundnut. The observed effects were ascribed to retarded photosynthetic activity due to shading created by tall growing cereal crops on the groundnut crop canopy.

A study of parent progeny regression analysis and heritability in narrow senso between F, and F, population of three inter varietal crosses for six quantitative traits indicated that the correlation and regression co-efficients between F mean and corresponding parental F values were significant for plant height, ear length and 100 grain weight in one cross, number of leaves and ear weight in another cross and plant height and number of leaves in a third cross. This indicates that the transmission of genetic potentialities from F, to F, is more and is attributed to additive gene effects. Hence, the scheme of selection in the segregating game- rations will be effective for these characters of respective crosses. The correlation and regression co-efficients between F, mean and corresponding parental F, values were not significant for grain yield in all the three crosses.

Field studies were made with three BPH resistant varieties i. e. JET, 7573, IET 7574 and IET 7575 during 1984-85 (karif and rebi seasons) at the Directorate of Rice Research, Rajendranagar farm, to assess the suitability of these varieties under normal and late plantings. The grain yields were assessed with young (26 days) and aged (55 days) seadlings cultivated under two types of planting. It was observed that young seedlings though contributed to more number of tillers and panicles, the spikelet and grain number were low in comparison to old seedlings observed under normal planting. In late planting, there was severe reduction in tillors panicles, spikelets and grains aniong the two age groups. The study therefore indicates that among the two seasons, use of old seedlings (50-55 days was beneficial under normal planting for realising good yield and exploiting productivity with BPH resistant varieties.

In a line X tester cross, heterosis was studied in 24F, hybirds of two Triticum timopheevi based Cms lines of Indian cultivars with different mutated restorer lines of exotic origin. The heterotic potential over mid and batter parents was present in many crosses for yield and its components. Maximum heterosis was noted for 100- grain weight followed by yield per plant. Next in descending order were grains per spike, spikes per plant and spikelets per spike. Fourteen out of 24F, hybrids showed highly significant positive heterosis over mid parent for grain yield. But incidence of significant heterosis over better parent remained a limiting factor due to the effect of male sterility in hybrid combination.

Twenty-eight gonotypes of Safflower (Carthamus tinctorius L.) were evaluated under rainfod and irrigated systems of cropping. The D analysis has revealed that twenty oight genotypes formed into as many as nine and thirteen clustors under rainted and irrigated cropping systems. There is some amount of parallelism in the genotypes, PI 248849 and PI 209291, not only in the clustering but also the distance between the clusters. The path analysis indicated that number of branches and number of heads per plant are the important contributing factors for yield both directly and indirectly. The genotypes K-1. Pl 199901 and PI 248827 are the desirable types for these traits.

A field experiment was conducted in the lateritic soil of Instructional Farm, Vellanik- care to study and estimate the grain and loss of water in the soil such as rainfall, run- aff, evapotranspiration, effective rainfall and deep percolation on rainfed cassava under various cultivation techniques which are common in the State. Profile moisture storage upto 150 cm depth of the soil was determined with neutron scattering method. It is nferred that the maximum water storage capacity of the soil under actual field condi- lons cannot be taken as its field capasity measured at 0.3 bar pressure. Evaporation rom bare land surfaces were much lower than the ET estimated under cultivated plots. in equation was suggested for finding out crop ET based on measurement of surface oil moisture content and potential avapotranspiration.

Fourteen genotypes of ragi wore investigated in terms of yield and its associated characters. The general association of yield with drymatter production was brought out Genotypes CO 7, IDS 1 and Indaf 5 doviated indicating their susceptibility to environment. The yield and 1000-seed weight relationship presented a wide scatter. The seed weight before sowing and seed weight after harvest differed widely in certaion genotypes. HPB 7 6 and PES 172 improved their 1000-seed weight largely whereas Indal 5 presented a decline. Only HR 222 showed resistance to environment interaction without any change in 1000-seed weight. Thus Genotype x Environment interaction is evident in the dry matter production and 1000 seed weight.

Studies made on the field recovery of Eucalatorja bryani Sabroky from Heliothis armigera Hubner indicated that there was effective parasitism from December, to April to an extent of 20 per cent and emergence of adult flies was 9 from each parasitised larvan The pencentage of parasitism and emergence of adult flies were significantly high from the larvae of Heliothis armigera collected from tomato followed by redgram and Lab-lab. A positive correlation was found to exist between the number of larvae parasitised vs. percentage of parasitism as well as with the number of adult flies emerged. Regression: equation fitted with the above variables showed that for every parasitised host larvas in the field, there would be an increase of 5.63 per cent parasitism and 3.73 adult flies emergence. These studies significantly revealed the practical utility of this parasitoid for effective parasitism on Heliothis armegera by mass multiplication and release in the field.
