Abstract
An experiment was conducted on “Effect of different levels of organic manures on physico-chemical properties of soil under cowpea crop in an inceptisol of Prayagraj, Uttar Pradesh, India” to observe the combined effect of farmyard manure, Vermi Compost and Neem Cake on soil health and yield. The result showed that the application of FYM, Vermi Compost and Neem Cake had a significant and non-significant effect on soil Physico-chemical properties, respectively. The maximum bulk density (1.32 Mg m-3 and 1.35 Mg m-3 ), particle density (2.46 Mg m-3 and 2.48 Mg m-3 ), pH (7.47 and 7.49) and EC (0.251 dS m-1 and 0.248 dS m-1 ) were recorded in T1(absolute control) at 0-15 cm and 15-30 cm depth. Similarly, the maximum percentage pore space (48.92 % and 45.47 %), water holding capacity (43.96 % and 40.38 %), organic Carbon (0.49 % and 0.47 %), Available Nitrogen ( 301.14 kg ha-1 and 294.97 kg ha-1), Available Phosphorus (30.96 kg ha-1 and 27.50 kg ha-1), Available Potassium (196.58 kg ha-1and 188.41 kg ha-1) were recorded in T9 treatment.
