| Abstract | ||||
| In 2019 and 2020 seasons, on sandy soil private farm at Nefisha, Ismailia Governorate using surface irrigation, the effects of eight combinations of four potassium levels (0, 25, 50 and 75 kg K2O/fad) and two micronutrients foliar spraying doses (Viz. with or without micronutrients mixture) on two peanut (Arachis hypogaea L.)varieties (Viz. Giza 6 and NC 9) were studied. NC 9 variety significantly surpassed Giza-6 variety in all studied characters (plant height, number of branches/plant, fresh straw weight/plant (g) dry straw weight/plant (g) number of pods/plant, weight of pods/plant (g), weight of seeds /plant (g), weight of 100 pods (g), weight of 100 seeds (g), seeds weight per 100 pods (g) and shelling percentage = (seed yield/pod yield) × 100). Plant height, weight of 100 pods, weight of 100 seeds, seeds weight per 100 pods, seed oil percentage and pod, seed, oil, fodder and biological yields/fad were significantly increased by raising potassium fertilization rate up to 75 kg K2O/fad either under spraying plants with micronutrients or without it.For all aforementioned characters, a significant interaction between potassium fertilization, micronutrients spray and peanut varieties was recorded. The highest values of the previous traits were produced from NC9 variety fertilized with 75 Kg K2O /fad and sprayed with micronutrients. While the lowest values were achieved from Giza 6 variety unfertilized with potassium and unsprayed by micronutrients. The study recommends planting NC9 cultivar, fertilizing at a rate of 57 kg K2O/feddan, and foliar spraying with microelements under the conditions of Nafesha area, Ismailia governorate. | ||||
