| Abstract | ||||
| Two field trials were carried out in the Farm of the Faculty of Agriculture, Demo, Fayoum University, Egypt, during the two successive summer seasons 2016 and 2017, to study the effect of sowing dates and seeding rates on yield and its components and quality of peanuts in newly reclaimed land. The experimental design was split-plots design in RCBD with three replicates, where sowing date (1st, 20th April, 10th and 30th May) were assigned to the main plots, and seeding rate at 30, 40 and 50 kg/fad. (one feddan = 4200 m2) were distributed in the sub-plots. The obtained results could be summarized as follows. Sowing on April 1st gave significantly highest on all studied traits at harvest like plant height, number of branches, number of pods per plant and weight of pod per feddan (1.87 and 1.92 t\fed.), seed yield per feddan (1.06 and 1.15 t\fed.) and oil yield per feddan (512.61 and 573.81 kg\fed.) in both seasons. Decreasing the seeding rate from 50 to 30 kg\fed produced significantly for all studied traits at harvest like plant height, number of branches, weight of pods (41.85 and 44.27 g), weight of seed and oil %. On the other hand, increasing the seeding rate from 30 to 50 kg\fed produced significantly the highest values of yield in terms of pod (1.89 and 1.87 t\fed.), seed (1.01 and 1.04 ton\fed) and oil (476.20 and 494.00 kg\fed) in both season respectively. There were highly significant effects due to the interaction between sowing dates and seeding rates on number of branches in the first season, weight of pods per plant and pod yield per feddan in the second one. The highest values of seed yield (1.21 and 1.34 tons) and oil yield (584.44 and 664.75 kg) per feddan in both seasons, respectively were obtained by sowing on 1st April and seeding rate of 50 kg/fed. The data revealed that, positive and highly significant (P ≤ 0.01) correlations were obtained between oil yield kg fed-1 and each of seed yield t fed-1 (r = 0.993** and 0.995**) and pod yield t fed-1 (r = 0.888** and 0.873**) in 1st and 2nd seasons, respectively. According to Stepwise results in data in Table 6 clarified that two traits i.e. seed yield and oil (%) in both seasons were significantly (P ≤ 0.001) contributed to variation in oil yield kg per feddan. | ||||
