Abstract
A study was conducted to assess fertilizer effect on wheat yield and soil fertility with the following treatments; T1- Control, T2- 100 % NPK, T3-75 % NPK + FYM, T4- 75 % NPK + FYM + PSB+ Azotobactor, T5- 100 % NPK + Zn, T6- 100 % NPK + Zn+ Mn, T7-100 % NPK + Zn + Mn + Fe, T8-75 % NPK + FYM+ PSB+ Azotobactor + Zn + Fe + Mn, T9-125 % NPK, T10- 125% NPK + Zn, T11- 125 % NPK + Zn+ Mn, T12-125% NPK + Zn + Mn + Fe, T13-100% NPK + FYM+ PSB+ Azotobactor + Zn + Fe + Mn and T14-50% N +100%PK + FYM+ PSB+ Azotobactor + Zn + Fe + Mn + LCC based N top dressing. Treatments differed significantly in influencing soil fertility and grain and straw yields of wheat crop. The study indicated that addition of 100% NPK + FYM + PSB + Azotobactor+ Zn + Fe + Mn recorded significantly higher value of growth and yield attributes in terms of plant height (cm), dry matter accumulation (g m-1), number of effective tillers (m-2) and yield attributes character grains spike-1,1000-grain weight (g), harvest index (%), grain yield (58.40 q ha-1) and straw yield (83.9 q ha-1) followed by 125% NPK + Zn+ Mn grain yield (57.9 q ha-1) and straw (82.9 q ha-1).The content of organic carbon increase with the combined application of organic and inorganic with biofertilizer. Integration of 100% NPK + FYM + Azotobactor + Zn + Mn + Fe was found more productivity and remvaerative with the higher residual soil fertility status after wheat crop. Based on the study, 100% NPK + FYM + Azotobactor + Zn+ Mn+ Fe could be recommended for attaining maximum wheat crop productivity and sustainability of soil under semi-arid and sub-tropical sandy loam.
