Abstract


A field experiment was conducted during growing season 2011 at Dabba station for Agricultural Scientific Research ( Lattakia region in syria) to investigate the response of four varieties of peanuts (ICGV 92022, C16 local 262, Souri, Al-Baladi) under different row spacing (40, 60 and 80 cm) and different seeding rate (one plant/hill, and two plant/hill) in terms of yield and seed content of oil and protein. The results showed the superiority of the local cultivar in seed yield (3529 kg / ha), whereas it revealed the superiority of ICGV92022 cultivar in terms of oil content (47.52%), while Souri cultivar surpassed significantly in protein content (27.69%)rewrite you can’t write this in English. The results showed significant effect of the row spacing on yields of seeds and content of oil and protein, where the 80 cm spacing between rows gave the highest value of oil (43.84%) and protein (26.50%) contents; whereas, the spacing of 40 cm recorded the highest seed yield (3261 kg/h). It was observed a significant increase in seed yield in the treatment of two plants / hill at the same time, which led to a significant decrease in both of the percentage of oil and protein compared with leaving one plant in the hill. Overall, the results showed that the local cultivar recorded the highest seed yield at the treatment (40 cm) apart between rows in addition to existence of two plants in the hill. However, for all studied cultivars and as a result of planting them at wide distances range between rows in addition to leaving one plant in the hill, it was noticed a significant effect on the quality of each of seed oil and protein contents.
