Effect of potassium and zinc on growth and yield of rabi pearl millet (Pennisetum glaucum L.)

A field experiment was conducted on the medium black calcareous soil of Instructional Farm, Junagadh Agricultural University, Junagadh to study the effect of potassium and zinc on growth and yield of rabi pearl millet [Pennisetum glaucum (L.) R. Br. Emend Stuntz) var. GHB 538 during rabi season of 2007-08. The 12 treatment combinations consisting of four levels of potassium and three levels of zinc were tried in factorial randomized block design with three replications. The results revealed that potential production and profit from rabi pearl millet cultivar GHB-538 could be secured by fertilizing the crop with 120 kg K2O alongwith 30 kg ZnSO4/ha in the medium black calcareous soil of South Saurashtra Agro-climatic region.
