Abstract: A field experiment was carried out at the Agricultural Farm of Rajiv Gandhi South Campus, Banaras Hindu University, Barkachha, Mirzapur to study the effect of phosphorus and zinc fertilization on production potential and physico-chemical properties of soil under pearlmillet in semi-arid eastern plain zone of India. On experimental data basis significant improvements were recorded in physic-chemical properties of and production potential of pearl millet. The pH and EC of the post harvest soil varied from 4.94 to 5.36 and 0.03 to 0.06. The highest soil pH and EC were observed in treatment P20Z10. The lowest pH and EC value was recorded in treatment P10Z30. The available nitrogen, phosphorus and potassium content in the post harvest soil of pearl millet ranged between 160.93 to 220.7, 8.14 to 25 and 169.0 to 197.3 kg ha-1, respectively. The highest N and K content in post harvest soil were recorded in the treatment P10Z10. The maximum P content in soil (25 kg ha-1) was recorded in the treatment where a combination of 30 kg ha-1 P and Zn was applied (P30Z30). The DTPA extractable Zn content in soil increased significantly from 1.22 to 4.51 mg kg-1, maximum DTPA extractable Zn content (4.51 mg kg-1) was recorded in the treatment P30Z30, however, minimum (1.22 mg kg-1) was recorded in control.
