Influence of Different Organic Manures on Wheat Productivity

Abstract

Manures are significant organic source of plant nutrients. Farmer’s awareness is increasing towards organic farming due to high cost of synthetic fertilizers and nutrient composition in Wheat grain all over the world. A spring wheat cultivar was used in an experiment. In this experiment five organic manures were used; green manure (GM), farm yard manure (FYM), poultry litter (PL), press mud (PM) and sewage sludge (SS). Each manure was used at the rate of (@) 10 ton per hectare ( t ha -1 ). Six different treatments were made with different combination of these manures along with one treatment having recommended dose of NPK (150, 115, 60 kg ha -1 NPK, respectively) and one control treatment with no fertilizer at all. The results indicated that the combination of GM+PL+SS each @ of 10 t ha -1 gave maximum economic yield (3.65 t ha -1 ), which was 137% more from control. PL and SS each @ 10 t ha -1 followed by green manuring should be used as organic manure in wheat crop. © 2011 Friends Science Publishers
