Efficacy of different combination of chemical fertilizer doses on yield of groundnut in Saurastra region

Abstract

Groundnut (Arachis hypogaea L.) is an exhaustive crop and removes large amount of macro and micronutrient. No single source of element is capable to increase crop yield. Therefore, to study the relative effect of different macro and micro nutrient doses on yield and quality of kharif groundnut were studied in the present investigation. The results of the field experiment revealed that the application of higher rate of potassium without phosphorus and with optimum rate of nitrogen, iron, manganese, zinc and copper recorded maximum pod yield (2726, 2858, 2792 kg ha-1) in the year-1, 2 and pooled as compared to combine application of phosphoruas and potash with nitrogen and micronutrient. While, the application of higher rate of phosphoruas and potash with nitrogen and micronutrient recorded maximum haulm yield (3111, 4521, 3816 kg ha-1) in the year 1, 2 and pooled. The application of higher rate of phosphorus with lower rate of potassium recorded higher shelling percentage and test weight. While highest oil percent was recorded with higher rate of potassium with medium to higher rate of phosphorus.
