Abstract

The research was conducted under rain fed conditions of Rawalakot to check the effect of different organic and chemical fertilizers on yield and yield components in maize. Eight different treatments were evaluated by using regular arrangement of randomized complete block design (RCBD) with three replications. Sheep manure (SM), farm yard manure (FYM), and poultry manure (PM) were used as organic sources of nutrients while NPK was used inorganic sources. The test variety of maize was Pioneer-30Y87. The data was subjected to analysis of variance (ANOVA) to analyze the difference amongst different means using least significance difference (LSD). Results revealed significant effect of different nutrient treatments on the yield and morphological growth of maize. Maximum number of plants (11.00), plant height (212.80 cm), number of grain rows per cob (15.60), 1000 grains weight (188.90 g), grain yield (6836.7g) were recorded for Treatment T7 (Half recommended NPK fertilizer + farm yard manure. tons ha-1). This study showed that mixed use of inorganic and organic sources of nutrients could be a better soil nutrient amendment when applied at a ratio of 50% dose of farm yard manure (FYM) + 50% dose of NPK in the cultivation of maize under rain fed conditions of Rawalakot.
