 ABSTRACT

A field experiment was conducted during kharif and rabi seasons of 2015-16 and 2016-17 at Udaipur to evaluate the effect of weed and nutrient management on quality protein maize.The experiment consisted of nine weed management treatments viz., weedy check, hand weeding at 15 DAS and 35 DAS,  tembotrione 0.125 kg ha-1 at 20 DAS, alachlor 2 kg ha-1 as PE fb hand weeding at 35 DAS, atrazine 0.5 kg ha-1 as PE fb hand weeding at 35 DAS, tembotrione 0.125 kg ha-1 at 20 DAS fb hand weeding at 35 DAS, alachlor 2 kg ha-1 + atrazine 0.5 kg ha-1 as PE fb hand weeding at 35 DAS, alachlor 2 kg ha-1 as PE fb tembotrione 0.125 kg ha-1 at 20 DAS and atrazine 0.5 kg ha-1 as PE fb tembotrione 0.125 kg ha-1 at 20 DAS with three nutrient management treatments viz., NPK, NPK+Zn and NPKS+Zn, thereby making 27 treatment combinations. The experiment was laid out in split plot design, assigning weed management to main plots and nutrient management to sub plots. The treatments were replicated thrice. Maize cv. Pratap QPM-1 was used as test crop. Maximum reduction of weed density and dry matter as well as highest weed control efficiency (72.07 %) was recorded in crop subjected to atrazine fb tembotrione closely followed by alachlor fb tembotrione and two hand weeding at 15 and 35 DAS. atrazine fb tembotrione recorded the maximum growth characters and produced significantly higher grain (4516 kg ha-1) and stover (7459 kg ha-1) yield compared to other treatments. Nutrient management had no significant effect on weed density while weed dry matter was significantly affected by different nutrients during both the years. Nutrient application of NPKS+Zn significantly improved various growth parameters, viz., plant height and dry matter at successive growth stages and recorded significantly higher grain (4275 kg ha-1) and stover (7227 kg ha-1) yield.
