Abstract :
Pulse production is very low and become challenging problem against the requirement of increasing population of our country. Moreover, it has a numerous utilities and used primarily as a food crop because it is a major source of protein in cereal based diets for its high lysine content. Among the different phosphorus levels and frequency of boron levels under in treatment T11 i.e., N3 (20:60:20NPK) + 0.2% foliar spray of borax at 35DAS (pre-flowering) recorded maximum plant height (53.60cm), number of leaves plant-1 (21.16), number of branches plant-1 (6.76), no. of nodules plant-1 (8.80), dry weight (24.82g), crop growth rate (0.53g m-2 day-1), relative growth rate (0.04g g-1 day-1), number of pods plant-1 (42.46), average number of grain pod-1 (13.40), pod length (10.80 cm), test weight (47.00g) , grain yield (1.62 t ha-1), straw yield (2.85 t ha-1), protein content (24.56%) and harvest index (36.15%). Whereas the lowest value (48.26 cm,18.93 plant-1,6.20 plant-1, 5.53 plant -1, 20.02 g, 0.39g m-2 day-1, 0.03g g-1 day-1, 30.40 plant-1, 7.73 pod-1, 8.13cm, 41.06g, 0.99 t ha-1, 2.06 t ha-1 , 20.36 % and 32.58 %, respectively) in the treatment T1i.e., N1 (20:40:20 NPK). The highest gross return (Rs.78795.00 ha-1), net return (Rs. 57222.00 ha-1) and benefit cost ratio (2.65) were registered in treatment T11 i.e., N3 (20:60:20NPK)+ 0.2% foliar spray of borax at 35DAS (pre-flowering). Whereas the lowest value (Rs.48925.50 ha-1), (Rs.30075.50 ha-1) and (1.59), respectively in the treatment T1 i.e. N1 (20:40:20 NPK).
