A field experiment was conducted during rabi season 2021-22 at Sardarkrushinagar, Gujarat in loamy sand soil. Total
eight treatments were tested in randomized block design with four replications. Mustard variety GDM 4 was sown at a
distance of 45 cm x 15 cm. Various growth parameters viz. plant height and number of branches/plant, yield attributing
characters and seed yield (2324 kg/ha) and stover yield (5381 kg/ha) were recorded significantly maximum with the
application of RDF+ 4.0 kg ZnSO4
/ha and 7.5 kg FeSO4
/ha soil application at basal + 0.5% ZnSO4
and 0.5% FeSO4
foliar
spray at 30 and 45 DAS (T8
). While, number of siliquae per plant was found significantly higher in application of
RDF+ 8.0 kg ZnSO4
/ha and 15.0 kg FeSO4
/ha soil application at basal. Application of RDF+ 4.0 kg ZnSO4
/ha and 7.5 kg
FeSO4
/ha soil application at basal + 0.5% ZnSO4
and 0.5% FeSO4
foliar spray at 30 and 45 DAS (T8
) recorded significantly
higher nutrients uptake of nitrogen, phosphorus, potash, sulphur, zinc and iron by mustard crop.
