ROLE OF ORGANIC AND INORGANIC NUTRIENT SOURCES IN IMPROVING WHEAT CROP PRODUCTION

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.
