A field experiment was conducted during zaid season of 2015 at Agronomy research farm of N. D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) to evaluate the long-term effect of organic sources with weed and pest control management practices against integrated use of nutrient sources (chemical + organics) and chemical fertilizer alone on growth and yield of greengram. Three sources of nutrients viz. inorganic, organic and bio-fertilizers were used in six combinations with randomized block design and replicated four times. The growth characters like plant height (34.7 cm), number of branches (6.5), number of nodules per plant (23.5), dry weight of nodules (67.3 mg/plant), yield attributes viz. number of pods per plant (32.3), number of seeds per pod (8.9), test weight (36.91 g), seed yield (11.6 q/ha), stover yields (26.1 q/ha) and harvest index (30.76 %) was influenced significantly by integrated use of nutrient sources viz., 50% recommended doses of NPS through chemical fertilizer and 50% N through FYM which was at par to the 100% chemical fertilizer (NPS) treatment. The organic treatments received 100% recommended N combindly through FYM + neem cake + vermicompost (1/ 3 from each source) along with weed and pest control measures provided comparable yields to fertilizer treatment.
