EFFECT OF IRRIGATION AMOUNTS AND FERTILIZATION ON YIELD AND QUALITY OF SOYBEAN
Two field experiments had conducted in of 2012 and 2013 summer seasons at Deir Mawas, Menia Governorate, Egypt to study the effect of irrigation amounts applied with center- pivot sprinklers and fertilization on yield and quality of soybean. The results indicated that application of 2880 m3 /feddan (4200 m2) significantly surpassed application of 2240 and 1600 m3 /feddan in plant height, number of pods and seeds/plant, seed index and seed yield/plant. The highest seed yield/fed. was obtained with irrigation by 2880 m3 /fed., which was 52.2 % higher than irrigation with 1600 m3 /fed. (0.620 ton/fed.). The maximum oil content (20.74 %) and protein content (41.79) had achieved with irrigating by 2240 m3/feddan. However, the highest yields of oil (266.52 kg/fed) and protein (534.88 kg/feddan) had obtained from irrigation by 2880 m3 water/feddan.
The highest soybean plant height, number of pods and seeds/plant, seed index and seed yield/plant were obtained with addition of NPK compound (19:19:19) with15 units of each elements (F2). In addition, F2 fertilizer treatment recorded the highest values of seed, oil and protein yields/feddan and IWUE. On the other hand, application of NPK compound (19:19:19) with 7.5 Kg of each element/feddan(F4) produced the highest oil and protein contents in seeds (21.28 and 43.06 %, respectively). The interactions between the amounts of irrigation and fertilizer treatments revealed highly significant differences in plant height, number of seeds/plant, seed index, seed yields per plant and feddan, oil and protein contents and yields. Irrigation by 2880 m3 /feddan with addition NPK compound (19:19:19) with 15 Kg of each element/ feddan significantly gave the greatest values of plant height, seeds/plant, seed index, seed yield/plant and yields/feddan of seed, oil and protein.
