Studies of nutrient content pattern in turmeric at different growth stages as influenced by graded levels of nitrogen under Acacia mangium based agroforestry system

Abstract

An experiment was conducted to study the effect of nitrogen levels on nutrient content pattern in turmeric at different growth stages grown under Acacia mangium based Agroforestry system in lateritic soils of Konkan during Kharif 2019 with four nitrogen levels (100%, 80%, 60% and 40% recommended dose of N) along with 100% recommended dose of P and K was applied to turmeric Cv. Salem grown under thirteen year old plantation of Acacia mangium under Agroforestry system and compared with absolute control. The data revealed that application of 100% N + 100% PK (T2) recorded the higher values of macro and micro nutrient contents in turmeric plant, which was found to be at par with 80% N kg ha-1 + 100% PK kg ha-1 in all cases.
