Influence of integrated weed management on weed dynamics and productivity of chili
integrated weed management in chili
To study the effect of organic and inorganic nutrients application in vegetable pea on performance of vegetable pea in vegetable pea-maize cropping sequence, a two years field experiment was conducted on the experimental farm of the College of Post Graduate Studies (CAU-I), Umiam, Ri-Bhoi (Meghalaya) during 2014-15 and 2015-16. The treatments included three organic nutrient sources viz., FYM (5 t ha-1) (B1), Rhizobium + phosphorus solubilizing bacteria (PSB) (B2) and Rhizobium + PSB + FYM (5 t ha-1) (B3), and six inorganic nutrient sources viz., RDF (F1), RDF + Lime (0.5 t ha-1) (F2), 75 % RDF (F3), 75 % RDF + Lime (0.5 t ha-1) (F4), 50 % RDF (F5) and 50 % RDF + Lime (0.5 t ha-1) (F6) were replicated thrice in randomized block design. Among organic nutrient sources, treatment B3 recorded maximum values of growth, yield attributes, yields and economic returns which were high over B1 and B2 in both the years however, plant height, pod length, number of grains pod-1, seed index, harvest index, net return and B:C ratio in both the years. Similarly, gross return, net return and B:C ratio did not differ significantly due to organic nutrients application in pea in both the years except for gross return in second year B3 recorded significantly high gross return over B1 and B2 organic sources application in pea. Among inorganic nutrient sources, maximum values of growth, yield attributes, yields and economic returns were observed from F2 treatments those were significantly high over the same recorded from remaining inorganic nutrient treatments to vegetable pea in both the years except for seed index in first year and stover yield and harvest index in both the years.
Key words: Vegetable pea, Dry matter, Pod yield, Net return, B:C Ratio
