Methodology: About 4-6 leaf stage seedlings of 18 temperate genotypes of Cape-gooseberry were arranged in the field in Randomized Block Design with three replications. Each plot consisted 3.00 m x 2.00 m with spacing of 60 cm and 45 cm between and within rows, respectively. Recommended package of practices were applied to raise a good crop. The data were recorded on ten randomly selected plants for eight characters viz., plant height, number of fruit bearing branches per plant, number of fruits per plant, fruit diameter, fruit length, fruit weight, total soluble solids and fruit yield per plant at maturity, and finally data were subjected to statistical analysis to derive valid conclusion. Results: Significant variation was observed for yield and all the yield traits studied except for plant height. High heritability was observed for fruit weight (0.85) and Total solble solids (0.87). Genetic advance was high for branches per plant (25.87), fruit yield per plant (23.21) and fruit weight (22.57). The fruit yield per plant was strongly positively associated with number of fruits per plant, fruit weight and Total soluble solids at genotypic level. Interpretation: Exhisting variability can be utilized for improvement of the crop. Number of branches per plant and number of fruits per plant are governed by additive genes. Heterosis breeding can be rewarding for the trait having high heritability coupled with low genetic advance. Strong genotypic correlation indicated that yield can be enhanced by giving due weightage to number of fruits per plant, fruit weight and total soluble solids during selection.

The current study was conducted to determine whether Trichoderma could be used to alleviate drought stress in rice. Methodology: Three distinct isolates of Trichoderma harzianum [94 (A),T-14, IRRI-2] obtained from the International Rice Research Institute India, as well as two native isolates of Trichoderma asperellum (OT-3) and Trichoderma harzianum (0T-8) obtained from the farmlands of OUAT through serial dilution, were inoculated through seedling root dip treatment. Different morphological (days to active tillering, plant height, panicle initiation, root length, leaf rolling score, number of unfilled and filled grains per panicle) and biochemical data (Total phenolic content, malondialdehyde, proline, hydrogen peroxide, lignin and peroxidase) were estimated to determine the stress due to drought. Results: In-vivo studies on plant height, root length, number of filled grains, grains per panicle and leaf rolling that are positively associated with grain yield revealed that the application of Trichoderma had increased the grain yield. The effect of various biochemical characteristics, such as increase in phenol, peroxidase, lignin and cell membrane stability, which are known to alleviate drought stress through a variety of mechanisms were observed in this study.

Methodology: Two highly acidic soils collected from the farmer’s field of South 24 Parganas district, West Bengal having no history of acidity management were used. The soils were treated with different rates of lime requirement (LR, ⅔LR & ½LR) and lime (½LR) + vermicompost (5 tha-1) treatments and incubated for 60 days. Soil pH, soil organic carbon content, different microbial populations, microbial respiration and enzymatic activities (FDHA and DHA) were assessed at different days. Results: The study indicated that the lime treatments showed rapid increase in soil pH towards the slightly alkaline condition whereas lime +vermicompost treatment (T5) successfully maintained the neutralized condition. Integrated treatment of lower doses of lime and vermicompost (T5) was found to efficiently promote the microbial population (rhizobium, phosphate and potassium solubilizing bacteria) and microbial respiration (basal and substrate induced respiration) activity, which might be attributed to the improvement soil microbial status. FDHA and DHA increased significantly with ‘lime’ as well as the ‘lime with vermicompost’ treatments in comparison to control. Interpretation: The incorporation of lower amount of lime and organic matter efficiently neutralizes the acidity and boosted up the microbial activities simultaneously that in turn might improve the soil health. The high cost to purchase the huge quantity of lime as recommended LR (9.25 tha-1) for studied soils turns the farmers uninterested to follow lime practice and interrupted the mitigation of soil acidity. Thus, the study might conclude that the integrated approach of lime application@½LR with vermicompost might successfully ameliorate the acid soils in terms of acidity as well as the soil microbial activities.

Therefore, the present study was planned to identify resilience of different heterotic combinations to heat stress under field conditions. Methodology: A set of 20 parental lines were used as parents and 21 single cross hybrids raised in kharif 2020 using 16 lines as female parent and four lines as male parent along with three commercial checks using randomized block design under two regimes: Normal Sownin mid of February, i.e., timely sown condition (spring season crop) and late sown in mid of March (heat stress crop). Data was recorded for yield and its contributing traits. Results: Heat stress led to early onset of flowering, thus resulting in shortening of vegetative phase. Consequently, days to grain filling period was found to be reduced (84-106 days) under late sown as compared to 100-123 days under normal sown condition. Amongst the top performing six hybrids in both normal sown and late sown conditions, three hybrids were common viz., JH 20003, JH 20015 and JH 20018, though with different ranking, inferring their wider adaptability and tolerance to heat stress. Under late sown conditions, days to grain filling (r2=0.55) and thousand seed weight (r2 =0.50) showed significantly positive correlation with grain yield while as highly significant and negative association was observed between anthesis silking interval and grain yield (r2 = -0.76).
