تأثير موعد الزراعة و الرش الورقي بمستحضر سماد الكرومور في الحاصل الأخضر لثلاثة أصناف من اللوبيا المزروعة في الموسم الخريفي

The experiment was conducted in a special field in the area of kanaan, diyala province for the autumn season 2017 to study the effect of planting date and foliar by grow more fertilizer in the growth and yield of three varieties of cowpea. The study included three factors: the first three varieties of cowpea namely Black eye, Kafr AlSheikh and Ramshorn, while second factor: planting date the first of 15/7/2017 and the second 1/8/2017. The third factor is the spraying of the leave in Grow more fertilizer included three levels, in addition to the control treatment (0 mg L-1 where distilled water was used). the experiment contained twenty four treatments which are the combination of the levels of the above factors. The experiment was carried out according to the split split plot system in the random complete block design (RCBD) and with three replicators. The results were analyzed using the SAS program, and the differences between the averages were measured by a Tukey test at a probability level of 0.05. The results were summarized as follows: The Kafr El-Sheikh cultivar was significantly higher in number and length of pods and yield of plant per and the total yield t h-1 , reaching 95.48 pods plant-1 , 18.10 cm and 1108.18 g-1 and 59.10 tons h-1 . while there were no significant between the varieties in the number of seeds by pod. One the first planting date gave high in all triats of studies.The level 100 mg L-1 of Grow more was significant in the total number of pods (49.49 tons h-1 ). While the levels 50 mg L-1 and 150 mg L-1 were significantly on number and length of pod and number of seeds in pod. Why the try interaction, is the Black eye significant first date under 100 mg l-1 on most of the traits studies.
