A field experiment was carried out during rabi  season of three consecutive years of 2017-18, 2018-19  and 2019-20  at Field Experimental Block, RRTTS, Keonjhar, Odisha  to study the effect of heat and thermal unit use of chickpea  cultivars under various dates of sowing. The experiment was laid out in a Split plot Design with twelve treatments combinations, four dates of sowing (1st November, 15th November, 30th November and 15th December) kept in main plots, and three varieties of chickpea (JAKI - 9218, JG-14, JG-16) in sub plots with three replications. The results of the experiments revealed that chickpea sown on 15th November registered the maximum mean grain yield of 1040 kg/ha, fetched maximum mean net return of Rs. 26895/- per ha with B:C of 1.89. Growing chickpea variety JAKI 9218 fetched maximum mean net return of Rs. 27850/- per ha with B:C of 1.67. The maximum GDD to reach maturity (2316.3 days) and heliothermal unit was recorded  on 1st November while minimum GDD of 1860.5 days was observed on 15th December. Among cultivars, JAKI 9218 had higher thermal unit requirement. Photothermal unit from date of emergence to maturity stage accounted higher with 1st November sowing, while lowest PTU were observed with the crop sown on 15th December during both all the years.  Variety  JAKI 9218 accounted non-significantly higher PTU than JG14 and JG 16 at all the phenological stages of the crop during all the years.

Dolichos bean, Lablab purpureus Linn is one of the important vegetable crops grown in India. Among the different pests infesting the dolichos bean crop, hairy caterpillar, Euproctis icilia Stoll is the most serious pest and damages the dolichos bean from seedling to maturity stage. A statistically designed field experiment was conducted with randomised Block Design with three replications and eleven treatments during Rabi season of 2007- 08 with a view to test the relative efficacy of some insecticides for the control of hairy caterpillar. The results revealed that insecticidal treatments viz., 0.002 per cent emamectin benzoate, 0.006 per cent cypermethrin + profanophos and 0.05 per cent DDVP + 0.1 per cent carbaryl were found to be most effective for the control of hairy caterpillar, E. icilia. All the insecticidal treatments were significantly superior over control in reducing the hairy caterpillar population.DOI: http://dx.doi.org/10.3126/ijls.v8i3.10308 International Journal of Life Sciences Vol.8(3): 2014: 5-7
