Abstract:

A field experiment was undertaken during kharif of the year 2016 at the Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), Bihar. The experiment was conducted in split plot design having three levels of nitrogen in main plots (N1-120 kg N/ha, N2-140 kg N/ha and N3-160 kg N/ha,) and six weed management practices (W1- Pyrazosulfuron @ 25 g/ha (20 DAS), W2-Bispyribac sodium @ 25 g/ha (20 DAS), W3-Pyrazosulfuron @ 25g/ha + Bispyribac sodium @ 25g/ha (20 DAS), W4 Pendimethalin @ 1000g/ha (PE)+ W3 (20 DAS), W5-Weed free (2 Hand weeding at 20 & 40 DAS) and W6-Weedy check) in sub plots, replicated thrice with Abhishek as the test variety. Higher level of nitrogen i.e. 160 Kg/ha exhibited better expression in respect of growth and yield attributes than the other two levels and it was somehow also comparable to 140 kg N/ha. The better performance in terms of growth and yield attributed were reflected correspondingly in grain and straw yield however harvest index didn’t show any significant variation due to nitrogen treatments. Nutrient uptake by crop was higher in 160 kg N/ha than other two lower doses. Amongst the two lower doses of nitrogen, 140 kg N/ha had an edge over 120 kg N/ha. The most glaring part of results rested in its economic studies, wherein treatment with 160Kg N/ha fetched higher gross returns, net return and finally B:C ratio than other two doses.
