A Study on the Nutrition of Peanut in Sandy Soil

This investigation aims to study the effect of optimum complete fertilizers and adequate soil amendments mainly Calcium as Gypsum on the yield and quality of Peanuts. Five experiments are designed to investigate the effect of Macronutrients, Nitrogen, Phosphorus and Potassium and their combined applications and soil amendments as Calcium carrier on the yield of Peanuts, its quality and its content of mineral Nutrients. The major Nutrients 24 kg k2O is also studied to estimate uptake the needed amounts of fertilizers to produce the highest economic yields. For fertilizer practice of Peanuts, the recommendation concluded from the different fertilizer treatments and their combinations is to add 10 kg N/acre in the early stage of growth 16 kg P2O5 per acre in the rooting zone before planting and 300 kg Gypsum per acre broadcasted to the fruiting zone at the early blooming stage.
