Response of Rice to Zinc Fertilizer in Calcareous Soils of D. I. Khan

M. Umar Khan, M. Qasim and M. Jamil


Response of rice variety IRRI-6 to various levels of zinc was studied in a pot culture experiment. Zinc was applied at the rate of 0, 5, 10 and 15 kg ha-1 in the form of ZnSO4 along with a basal dose of 175 kg N, 110 kg P2O5 and 100 kg K2O ha-1. The results showed that all the yield and yield components of rice increased significantly with increasing level of zinc fertilizer. However, significantly maximum plant height, average number of productive tillers per plant, panicles per plant, spikelets per panicle, 1000 paddy weight and grain and straw yield were obtained where Zn was applied at the rate of 10 kg ha-1 which was statistically at par with the treatments receiving Zn at the rate of 15 kg ha-1 except number of spikelets per panicle of rice.
