THE IMPACT OF DIFFERENT SEEDING DATES ON SEED YIELD OF SOYBEAN

Thisstudy was conducted to determine the effect of six different seedingdates (15 th April, 1 st May, 15 th May, 1 st June, 15 th June and 30 th June) on the yield and yield components of the soybean. Theexperimentaldesign was a randomized complete blockwithsplit plothavingfour replicates. The studies were conducted at GAP International Agricultural Research and Training Center in 2004, 2005 and 2006 years. The results indicated that the cultivars were significantly influenced by the different seedingdatesfor the traits of plant height (PH), first pod height (FPH), pod number (PN), weight for 100 seeds (SW), seed yield (SY), oil yield (OY) and protein yield (PY ),Itwas observedthatcv.NE3399 had the highestseedyieldwhilethe lowestseedyieldwasgiven byUMUT2002 .
