Abstract

An experiment on the response of mung bean to organic sources (Farmyard manure, poultry manure and crop residues @ 5 t ha-1) and nitrogen levels (20, 25, 30 kg ha-1) was carried at Agronomy Research Farm, The University of Agriculture, Peshawar and District Nowshera during summer 2015. One control plot (no organic matter and nitrogen) was also maintained. The experiment was triplicated in randomized complete block design (RCBD) with 10 (9+1) treatments in each replication under with and without organic matter sources and nitrogen levels. Location wise results showed better performance of mung bean at district Nowshera than Peshawar. Among various organic sources applied, poultry manure produced maximum number of branches plant-1, leaf area, fresh weight, dry matter, number of nodules plant-1, number of pod plant-1, number of seed pod-1, thousand grains weight, biological yield, and grain yield. While minimum values for all the above parameters were recorded in crop residues treated plots. Nitrogen application at the rate of 30 kg ha-1 produced maximum number of branches plant-1, leaf area, fresh weight, dry matter, number of nodules plant-1, number of pod plant-1, number of seeds pod-1, thousand grains weight, biological yield and grain yield, while 20 kg N ha-1 gave poor results of the recorded parameters.  The interaction between organic sources and nitrogen levels was found non-significant. While interaction between location and nitrogen levels significantly affected number of branches, number of nodules.  Interaction between organic sources and location significantly affected fresh weight gram m-1 and mean leaf area.
