Abstract

In order to study the effects of POTASSIUM FERTILIZER on yield and growth of soybean (Glycine max L.) an experiment as factorial in RCB design with three replications was conducted during 2006 and 2007 years at Northern Khorasan. Factors were cultivar (Hobbit, L.W.K., and Williams), and POTASSIUM FERTILIZER (0, 80, and 160 Kg K2o/ha). Results indicated that cultivar and K fertilizer significantly effected on seed yield. Williams showed that the highest seed yield. With increasing fertilizer application, seed yield increased significantly. The number of pod affected by all factors, but the number of node per stem, the number of seed per pod, 100 seed weight, and seed yield per branches affected only by cultivar. Growth analysis indicated that, potassium caused the improvement of dry matter accumulation, relative growth rate, crop growth rate, Leaf area index and net assimilation rate. Also, williams and L.W.K. showed higher GROWTH INDICES rather than hobbit.
