Study of RDF levels of NPK and micronutrient on growth and yield of mustard [Brassica juncea (L.)]

Abstract

A field experiment was conducted at Research Farm of Mewar University, Chittorgarh (Rajasthan) during rabi season of 2024-25 on loamy sand soil, which consisted ten treatments viz., Cntrol-T0, 50% RDF + ZnSo4 @ 5 kg/ha -T1, 50% RDF + Boron @ 1 kg/ha-T2, 50% RDF + ZnSO4 @ 5 kg/ha + Boron @ 1 kg/ha- T3, 75% RDF + ZnSO4 @ 5 kg/ha-T4, 75% RDF + Boron @ 1 kg/ha-T5, 75% RDF + ZnSO4 @ 5 kg/ha + Boron @ 1 kg/ha-T6, 100% RDF + ZnSO4 @ 5kg/ha-T7, 100% RDF + Boron @ 1kg/ha-T8, 100% RDF +ZnSO4 @ 5 kg/ha + Boron @ 1 kg/ha-T9 were applied to the musterd var. BIO-902 with randomized block design (RBD). The results of one year study clearly showed that the application of fertilizers (RDF level of NPK) and micronutrients brought significantly increased growth, yield and quality attributes of mustard. The growth and yield characters like plant height, number of dry matter accumulation, number of silique plant-1 and seed yield was significantly improved under 100% RDF +ZnSO4 @ 5 kg/ha + Boron @ 1 kg/ha T9 which was statistically remained at par with 100% RDF +ZnSO4 @ 5 kg/ha-T7.
