Effect of FYM and mineral nutrients on yield, content and uptake of nutrients in mustard

Abstract

A field experiment was conducted at Agronomy Farm of S.K.N. College of Agriculture, Jobner, Jaipur (Rajasthan) during the rabi season of 2005-06 using randomized block design with three replication to study the effect of FYM and mineral nutrients on seed and stover yield, content and uptake of nutrients in mustard. The experiment consisted of three levels of FYM viz., control, 5 t/ha & 10 t/ha and five levels of mineral nutrients viz., no mineral nutrients, 40 kg S/ha, 40 kg S/ha+ 25 kg ZnSO4 /ha, 40 kg S/ha + 50 kg FeSO4 /ha and 40 kg S/ha + 25 kg ZnSO4 /ha+ 50 kg FeSO4 /ha. The results revealed that each successive increasing levels of FYM and mineral nutrients individually and in combination significantly increased the seed and stover yield, content and uptake of nitrogen (N), sulphur (S), zinc (Zn) and iron (Fe) in seed and stover as compared to control. The combined application of FYM and mineral nutrients was found to increase Zn uptake in seed and Fe uptake in stover as compared to their individual application. The highest Zn uptake in seed (87.4 g/ha) and Fe uptake in stover (868.5 g/ha) was obtained under 10 t FYM/ha and 40 kg S/ha+ 25 kg ZnSO4 /ha+ 50 kg FeSO4 /ha (F2 M4 ) treatment.
