Abstract:
An experiment was conducted to study the effect of four levels of nitrogen (100%, 80%, 60% and 40% recommended dose of N) along with 100% recommended dose of P and K on growth, yield of turmeric and nutrient status of soil under thirteen year old plantation of Acacia mangium based Agroforestry system in lateritic soils of Konkan during Kharif 2019. The data obtained revealed that application of 100% N + 100% PK (T₂) recorded the highest rhizome yield to the tune of 30.44 q ha^-1 and higher values of available macro nutrients, which was found to be at par with 80% N kg ha^-1 + 100% PK kg ha^-1 in all cases. Thus, considering the growth and yield of turmeric, application of 80% N kg ha^-1 + 100% PK kg ha^-1 was found to be beneficial in lateritic soils of Konkan from the view point of saving 20% nitrogen fertilizer as well as getting higher rhizome yield and maintaining the soil fertility under Acacia mangium based Agro-forestry system.
