| Abstract | ||
| Field experiment was carried out at Al-Mohamadi city beyond to Heat town-Al-Anbar in the right bank of Enphrates River during 2012-2013 seasons to study the effect of planting dates and potassium spraying on the seed yield of of peanut(ArachishypogaeaL.) Local cv. Factorial experiment in RCBD design with three replications and two factors were used .First factor included six dates for planting (1st and 15th April, 1st and 15th May and 1st and 15 June), the second factor was three levels of potassium (4000, 5000 and 6000 mg Ka.L-1) in addition to control treatment (spray with water only). The result showed than 2ndplanting date (15th April) was superior in seed yield by increasing about 84.13 and 80.06% compared with 6th plantingdate (15th June) due to increasing No. of pods about 74.25 and 72.34% and No. of seed per plant about 64.05 and 44.14% for both seasons, respectively. Spraying potassium at 6000 mg K.L-1gave increasing in seed yield about 36.77 and 36.25% for both seasons respectively. The best combination was planting in 15thApril with spraying 6000 mg K.L-1 to obtain best seed yield of peanut. The conclusion of this study was good response of peanut seed yield to early planting dates in April and high concentration of potassium spraying 6000 mg K.L-1. | ||
