Banglaponics, a soilless cultivation technique comprised of traditional agricultural fertilizers in pond water mixed with cow urine has been used to evaluate the efficiency of tomato production. The production rate (237.85 ± 10.87 g/plant) was significantly (p < 0.05) higher in the Banglaponics medium than soil medium. Plant height, leaf number, leaf area, root number, root length, and flower number of the studied plant showed significantly (p < 0.05) higher in Banglaponics medium than plants grown in soil. Both treatments showed that chlorophyll score and antioxidant activity (DPPH) were almost equal. Banglaponically grown plant leaf, despite having lower Ca concentrations, possessed higher concentrations of Fe and Zn than those of soil-grown. Additionally, Banglaponically grown plant also showed significantly much lower Pb concentrations than that of grown in soil. On the contrary the other two heavy metals Cr and Cd, hold nearly the same value. By appearance, Banglaponically-grown plants were much healthier than that of soil-grown. This technique can be introduced in drought-prone areas of Bangladesh as it requires much less water than soil-grown tomato plants. Bangladesh J.

It is a dioecious plant and reported to have an excellent nutritive value, but mainly grown in homestead condition mostly in neglected ways. The present study was aimed to characterize the germplasm nature, details of flowering and fruiting system of Burmese grape. Tree growth habit and crown shape of all the accessions surveyed were semi erect and irregular, respectively. The colour of the male flowers varied from yellow to green yellow shades while the colour of the female flowers varied from yellow to yellow green and green yellow shades. The variation present on fruit length (2.81 cm to 3.80 cm), fruit weight (12.25g to 22.95g), pulp percentage (49.82% to 65.33%), total soluble solids (9.00º to 13.10ºBrix), tritatable acidity (0.73mg to 1.28mg/100g fruit pulp) and ascorbic acid content ranged from (23.18mg to 57.80mg/100g fruit pulp) suggest suitable selection method for identification of promising Burmese grape genotypes.

Eberhart - Russel model was used for stability analysis in rice. In this model, genotype mean across environments, regression of genotype on environmental index and function of the squared deviation from the regression were determined. Mean sum of squares against environment source of variation as well as linear component of environment were significant for all the studied characters suggesting a presence of variation among the environments tested. The linear component of genotype x environment interaction was also found significant for all the traits studied which indicated presence of significant differences between the genotypes. The landraces Kallurundaikar and Kattanur responded favourably to better environments but gave poor yield in an unfavourable environment. Hence, they are suitable for favourable environments. Sivappuchithiraikar and Mysore malli recorded the highest grain yield with bi value closer to unity and non-significant deviation from regression.

Germplasm stock exhibited huge variability for seed yield and its contributing traits with variable levels of yield reduction under late sown conditions. The per se yield based computed heat stress susceptibility index (HSI) ranged from 32.3 (highly THS susceptible) to -1.15 (THS tolerant).

This panel was evaluated under THS by raising crop underpoly-tunnels during reproductive phase along with same set of 96 genotypes raised under normal field conditions (served as control).

Eight treatments were arranged in a completely randomized design (CRD) with three replications including control. Application of VC8K60 (T5) resulted in the highest plant height (60 cm). However, VC8K60B0.4 (T8) recorded the maximum leaf number (17 plant-1), leaf area (264 cm2), fruit petiole (4.15 plant-1), fruit number (3.50 plant-1), total fresh (143.15 g plant-1) and dry weight (16.4 g plant-1). Application of VC8K60B0.4 (T8) helped the improvement of the N, P, K, S, Fe and Zn concentrations of the roots, leaves and fruits. Result of growth, yield attributes and nutrient content varied significantly (p ≤ 0.05). Hence, to achieve higher fruit yield with higher nutrient concentration the soil should be supplied with vermicompost, muriate of potash (50% K) and boric acid (17% B) at a required rate. However, for a good recommendation field trials are needed in major agroecosystems of the country. Bangladesh J.

For maximum lipase production, the optimum pH was 7 and the temperature was 37ºC. Using these conditions, the isolates were grown on media with additional carbon and nitrogen sources along with different inoculum concentrations. The maximum amount of lipase produced by Stenotrophomonas sp. ICMM10 was 136.47 ± 1.63 U/ml, which is 5-fold higher than before. Pseudomonas aeruginosa BA7823 produced a maximum lipase of 96.33 ± 0.21 U/ml, which was about 9-fold higher than before.
