The Effect of Foliar Application of Nitrogen at Different Dates, and Planting Method on Grain Yield, and Yield Components of Mung Bean in the Environmental Conditions of Khoramabad

In order to study the effect of foliar application of nitrogen at different dates, residue management methods and planting methods on yield and yield components of Mung bean, a field experiment was carried out in summer,2009 at Azad University Research field in khoramabad. Treatments were arranged in a strip- split plot using randomized complete block design with three replications. The planting method levels consisted of raised bed plots and no-tillage, wheat residue management consisted of burning straw and straw mulching, and foliar application of nitrogen consisted of four levels: no foliar application, foliar application in the rapid stage growth, foliar application before flowering ,and foliar application in the stage growth and flowering. Results showed that Mung bean in no-tillage had higher grain yield, biological yield, number pod per plants, Number of seed per pod and 1000- grain weight. Moreover, grain yield, biological yield, number of pod per plants, number of seed per pod and 1000-grain weight were significantly higher than burning straw. Foliar application in the stage growth and after had higher grain yield (627.1 ), biological yield (1507. 1 ), number of pod per plants (31.2), number seed per pod (13.2) and 1000- grain weight (47.2 gr.). It can be concluded that planting methods (No- tillage) straw mulching and foliar application in the stage growth and after,was considered superior, by producing 782 grain yield.
