Quantity/Intensity relationship as influenced by phosphate application by wheat

Abstract

The field experiments were conducted on wheat in rabi during the year 2017-18 at the Instructional Farm of Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri, in order to study the “Quantity/Intensity relationship as influenced by phosphate application by wheat”. The experiment was laid out in Randomised block design, with seven levels of phosphorus (0, 15, 30, 45, 60, 75 and 90 kg P 2O5 ha-1) with 3 replications. The results revealed that with increase in the phosphate levels, there was also increase in the quantity of phosphorus in the soil under the treatments applying 0,15,30,45,60,75 and 90 kg P2O5 ha-1 (T7), 0.32 Qo (X10-7 mol g-1 soil), 27 Ie (X10-7 mol L-1), 6.38 EPP, 17 PBC (L g-1 soil), the quantity (Qo), intensity (Ie) and capacity factors were improved which resulted in more availability of P in soil, which would serve as a balance for next crop
