Effect of Organic Manure and Foliar Potassium Application on Yield Performance of Wheat Cultivars (Triticum aestivum L.)
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 2
Abstract
In order to study the effects of organic manure (0 and 20 ton ha-1) and foliar potassium application form potassium sulfate (0 and 250 kg ha-1) on grain yield, yield components, leaf potassium content in 4 wheat cultivars including (Hamoon, Karkhe, Kavir and Yavarus), a factorial experiment based on randomized complete block design (RCBD) was carried out in the Kerman Agricultural and Natural Resources Research Centre, Iran during 2009-2010. Results showed that Organic manure increased number of grain per ear (9.17%), leaf potassium content (42.7%), and 1000 seed weight (4.81%) in compare with control. Increasing rates of applied potassium from 0 to 250 kg ha-1markedly increased all studied characters. Application of 250 kg ha-1 k increased the leaf potassium content 43%. There were significant differences among cultivars in all evaluated traits except number of grain per ear. The highest grain yield (6.1 ton ha-1) was found of 250 kg ha-1 potassium in Hamoon cultivar.
