Response of potassium with and without micro-nutrients in early rice under saline -alkaline soils

A field experiment was conducted to study the effect of 4 levels of potassium (0,30,60, and 90 kg K20/ha) in presence and absence of 5 kg/ha chealeted Iron and 5 kg/ha chealetcd Zinc with control for two consecutive years at Agricultural Research Farm of Sri Durga Ji Post Graduate College, Chandesar Azamgarh. The experiment was laid out in Randomized complete block design with 4 replications. A general application of 120 kg Nand 60 kg P205 was uniformly made. The potassium interacted with both iron and zinc in respect of grain yield. The two years data revealed that 60 kg K20/ha and 5 kg chealeted zinc enhanced the grain yield significantly. The interaction of potassium 90 kg K20 with 5 kg chealeted iron had promoted the grain yield in second year's study.
