Role of Organic and Inorganic Nutrient Sources in Improving Wheat Crop Production

Abstract

Abstract Effects of organic manures on grain yield and yield components of wheat (Triticum aestivum L.) cultivar Minthar-03 were studied at (RARI) Regional Agricultural Research Institute Bahawalpur, Pakistan, during 2010-2011 seasons in chemistry division. The present study have six treatments i.e. control, NPK=150-120-60 kg/ha, control, NPK= 150-120-60 kg/acre, NPK+ poultry manure 50 kg /acre, NPK + press mud 500 kg/acre, NPK + city compost 300 kg/acre, NPK + humic acid 4 kg/acre. Combinations of NPK + PM 50 kg/ha having high plant height (102.53) while number of (343) tillers/m2 was obtained high in combination with NPK + city compost 300 kg/ha which was at par with combination (NPK + press mud 500 kg/acre) having plant height 100.90. spike length, number of grains /spike, 1000 grains weight, grain yield t/ha was 13.35 cm, 61.85, 40.60 grams and 3.14 t/ha respectively obtained in treatment (NPK + press mud 500 kg/acre). While minimum amount of plant height (94.80), number of tillers/m2 (223), spike length (10.35 cm), number of grains/spike (43.43), 1000 grains weight (35.33g), grain yield t/ha (38.41) was found in control where no dose of organic and inorganic fertilizer were applied.
