Abstract: Maize crop was raised in split plot design with different nutrient management practices as main and different levels of gypsum and borax as sub treatment. The results revealed that pH at tasseling stage was reduced compared to initial soil pH significantly and EC at tasseling stage slightly increased from initial EC in main plots and gypsum treated sub plots, Organic carbon did not change significantly both main and sub treatments at both stage. At harvest significantly higher zinc availability in soil was recorded in 200 kg ha-1 gypsum treated plots compared to other plots where gypsum was not applied. Significantly higher boron availability in soil at both tasseling and after harvest was recorded in treatments where 2.5 kg and 5 kg borax were applied. The main treatments observed no significant difference in content of zinc and boron at tasseling stage and at harvest. Zn content at tasseling stage was non significant. But at harvest, content of Zn was highest in S1 treatment (control). Boron content among subplot treatments at tasseling stage and at harvest was higher in S4 treatment and it was on par with other treatments except S1 and S2.
