Influence of Nitrogen levels and weed control methods on quality of transplanted African Sarson

The experiment was conducted at Lovely Professional University, Phagwara on “Influence of Nitrogen levels and weed control methods on quality of transplanted African sarson”. The field study was conducted in Split Plot Design with four nitrogen levels in main plot (0, 75, 100, 125 kg/ha) and four weed control treatments in sub plot (T1= Pendimethalin 0.375 kg/ha followed by H.W. 40 DAT, T2= Straw mulching 8 t/ha, T3= H.W. 40DAT, T4= Weedy check). The crop gave significantly higher yield with use of 125 kg N/ha and quality parameters also increased with use of 125 kg N/ha but oil content decrease with increased in nitrogen doses. The chlorophyll content recorded at 45 and 75 DAT was higher in 125 kg N/ha. The protein content was significantly more with use of high level of nitrogen and oil content inversely proportional to protein content. The oil content was maximum recorded at 100 kg N/ha. The chlorophyll content, oil content and protein content was recorded significantly higher in all weed control treatments as compared to unweeded (control).
