تأثير مستويات النيتروجين والمسافة بين النباتات وتداخلهما في نمو وحاصل الماش

Abstract

Abstract:Two farming experiments have been practiced during the autumn seasons of 2008 and 2009 in the farms of AL-Mashrooa /AL- Mussyab / Babylon. To know the effects of nitrogenic fertilization levels and the distance among the plants in the growing and the product of the seeds and their components Vigna radiata variety (khadrawe) . The two experiments have been practiced in the random complete block design (R.C.B.D).By ordering the split plots, so the main plots represent the levels of nitrogen (0,50,100)Kg /N/H while the secondary plots represent the distance among the plants (20,30,40)cm. The data- which has been taken statistically- has been analysed giving the following results:The level of nitrogenic fertilization 50 kg N /H has exceeded by giving the highest some characters.The distance of plantation among plants (30 cm ) has exceeded by givining the highest mediums (11.86 ,10.66 )g / plant and(0.95 ,0.84 )Ton/H a for seed yields. The interferance between the nitrogen levels and the distance of the plantation among the plants has an significant effect in all the studied characters except the character of number of the pods for the plant.The combination (N1+D2) has exceeded by giving the highest mediums (15.63,14.65) g/plant and (1.19,1.03)Ton/H afor seed yields in the two agricultural seasons sequencely . We can conclude from this study that the best distance for the plantation among the plants is (30 cm) with the level of nitrogenic fertilization (50kg N/H) to get the highest product of the seeds
