In Bangladesh, sesame suffers from water-logging during its growing period. Multi-year and multi-location field trials were carried out to study the effect of different durations of water-logging at different growth stages on seed yield of sesame. From two years results, it is revealed that the effects of water-logging during a particular growth stage or particular duration of water-logging on seed yield depends on pre- and/or post water-logging from the rainfall. Differential effects of the cultivars were also observed. The cultivar Binatil-2 and Binatil-3 showed reasonable seed yield under water-logging at flowering and mid pod-formation stages for 24 to36 hours.

The effects of the dimethylamine salt of dicamba (3,6-dichloro-2-methoxybenzoic acid) and the dimethylamine salt of 2,4-D [(2,4-dichlorophenoxy)acetic acid] on fieldbeans (Phaseolus vulgarisL. ‘Great Northern Valley’) were studied in order to assess the potential hazards of using these herbicides in areas adjoining fieldbean production. Dicamba and 2,4-D were applied to fieldbeans at three different rates (1.1, 11.2, and 112.5 g ai/ha) and four different growth stages (preemergence, second trifoliolate leaf, early bloom, and early pod). Application of 2,4-D preemergence or in the second trifoliolate leaf stage of growth did not reduce seed yield, delay maturity, or reduce germination of seed obtained from treated plants. Dicamba or 2,4-D applied at 112.5 g/ha to fieldbeans in the early bloom or early pod stages of growth consistently reduced seed yield, delayed maturity, and reduced germination percentage. Fieldbeans exhibited a greater overall sensitivity to dicamba than to 2,4-D.

A field experiment was conducted during the winter (rabi) season of 2013-14 and 2014-15 at research farm Hisar, Haryana in a split plot design having four dates (Oct 15 and 25, Nov 5 and 15) in main plots and five nitrogen levels (0, 40, 60, 80 and 100 kg N/ha) in sub plots with three replications to study the effect of sowing dates and nitrogen levels on growth and yield of Indian mustard. Results revealed that October 15 sown crop resulted in significantly higher total plant biomass and its partitioning at different growth stages, yield attributes, yields and oil content. Delaying the sowing dates from October 15 to November 15 reduced seed yield by 39.3 percent. Among the nitrogen levels, application of 100 kg N/ha led to record higher total biomass and its partitioning at all growth stages and resulted in higher yield attributes and seed yield. Oil content decreased with increased levels of nitrogen.
