ABSTRACT
An experiment to find out the relative performance of two sources of organics and NPK is in progress in alluvial soils (Inceptisol) of College of Agriculture Gwalior, with nine treatments & 3 replications in randomized block design. Data presented has been obtained from the crop grown during Kharif 2014. Higher yield (4192.46 kg ha-1) in comparison to 100% FYM and 100% vermicompost was recorded with 50% vermicompost + 50% NPK and this was followed by 100% NPK ( 3891.6 kg/ha-1) The highest build-up of organic carbon in the soil was recorded in 100% NPK (4.61gkg-1), which was at par with 25% vermicompost + 75% NPK and 75% vermicompost + 25% NPK. A significant increase was noted in test weight under different treatments compared to two organic manure (FYM ana vermicompost). Its ranged from of 9.00 to 10.65 g under different treatments. Maximum test weight (10.65 g) was under 100% NPK. Maximum length of ear head (35.9cm) was recorded with T9 (100% NPK) treatment but statistically at par with T4 25% FYM + 75% NPK and T8 treatments 25% Vermi + 75% NPK, having length of ear head 30.0 & 32.4 cm respectively. The results indicate that 100% NPK treatment contribute the highest content of available soil micronutrients Cu, Fe, Zn, and Mn 0.456, 8.06, 0.785, 9.430mgkg- 1resppectively over remaining treatments. Two sources of organics resulted in lower concentration. In general the status of Cu, Fe, Zn, Mn declined in the soil samples after harvest in comparison to initial samples.
Key words: FYM, Pearl-millet, Cu, Fe, Zn, Mn, Micronutrient, Yield.
