Abstract:
نفذت هذه التجربة في المشتل التابع لمديرية زراعة محافظة ديالى خلال الموسم الخريفي لعام 2014 في تربة ذات نسجة طينية رملية بهدف معرفة تاثير الاضافة الارضية والتغذية الورقية بالبوتاسيوم في بعض المؤشرات المظهرية والفسلجية للذرة الصفراء Zea mays.L.. تضمنت التجر | This study has been achieved in a nursery that belongs to the Directorate of Agriculture of Diyala governorate in autumn 2014. The soil in which the corn is grown was Sandy clay. The aim of this study is to know the effect of Potassium application by Soil and Foliar in some morphological and Physiological Parameters of Corn (Zea mays L.) Buhooth 106. The randomize complete block design (RCBD) was conducted in this study with three replications Ground addition 80, 40, 20, 0 kg. k.ha - 1 and foliar applications (0, Spray with water, 3000 and 4000 mg k.L - 1) as Potassium sulfite (41.5% K). The results show that there are differences in the third level (40 Kg.K.ha - 1). The differences are in the Plant height (162.4 cm) , Leaf Area (518. Dsm2) , Stem diameter (10.7 cm) , Weight of 100 grains (22.7 g) , grain yield of plant (107.2 g.plant - 1), number of Leaves per plant (12.8) , ear Length (20.0 cm) number of grain per ear (641.8). number of rows per ear (16.5), dry matter of green plant (46.2.g.plant - 1) Chlorophyll index (48.7 Spade unit) and concentration of protein and Potassium in the leaves. Using K Foliar application treatment was 4000 mg.L - 1 caused Significant difference in the plant high (159.1 cm), Leaf Area (505.1 dsm2) , Steam diameter (10.7 cm) , weight of 100 grain (21.8 g) , grain Yield of plant (109.7 g.plant - 1), number of Leaves (13.0), ear Length (20.4 cm) , number of grain Per ear (633.4) number of rows per ear (16.7) , dry matter yield per plant (39.5) chlorophyll content (50.7) and concentration of protein (2.62%) and concentration of Potassium in Leaves (1.75%) The interaction between the Level 40 Kg.K - 1 as ground addition and 4000 mg.L - 1 as Foliar application gives the best results in all parameters.
