Nitrogen uptake and yield of groundnut as influenced by secondary and micronutrients

Abstract

A field experiment was carried out at on sandy loam soils of Agricultural College farm, Mahanandi during rabi season of 2015-2016 to study the response of groundnut to secondary and micronutrients. The experiment was laid out in a randomized block design with ten treatments and replicated thrice. The treatments consisted of T1: Control, T2: RDF: 20-40-50 kg N-P2O5-K2O ha-1, T3: RDF + foliar application of 1% CaNO3,T4: RDF + foliar application of 1% MgNO3, T5: RDF + foliar application of 1% Sulphur, T6: RDF + foliar application of 1% each of CaNO3, MgNO3 and Sulphur, T7: RDF + foliar application of ZnSO4 @ 0.2%, T8: RDF + foliar application of 1% each of CaNO3, MgNO3 and Sulphur + ZnSO4 @ 0.2%, T9: RDF +foliar application of micronutrient mixture @ 0.2%, T10: RDF + foliar application of 1% each of CaNO3, MgNO3 and Sulphur + micronutrient mixture @ 0.2%. Data collected on yield and nitrogen uptake of groundnut were subjected to statistical analysis and results indicated that all the characters studied were significantly higher with application of RDF + foliar application of 1% each of CaNO3, MgNO3 and Sulphur + micronutrient mixture @ 0.2% (T10).
