Integrated nutrient management of rapeseed (Brassica campestris L. var. yellow sarson) grown in a typic haplaquept soil
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 2
Abstract
The present investigation was conducted to study the influence of integrated nutrient management on fertility build up in a Typic Haplaquept soil as well as its effect on yield and quality parameters of rapeseed (Brassica campestris L. var. yellow sarson). Treatments comprised of recommended doses of N, P and K fertilizers (RDF) in presence and absence of FYM along with different doses of S and Zn either alone or in combination. Results revealed that in general, available N, P, K, S and Zn in soil decreased with increase in the period of crop growth. Addition of FYM increased organic carbon content in soils (upto 104.98 g kg-1increase over initial value). Application of elemental S and Zn-EDTA increased SO4-2 content (upto 101.03 kg ha-1 increase over initial value) in S-treated and DTPA extractable Zn content (upto 0.3 mg kg-1 increase over initial value) in Zn-treated systems respectively. Combined application of higher doses of S and Zn along with FYM and recommended doses of N, P and K fertilizers increased N, P, K, S and Zn uptake by rapeseed crop. Highest seed yield (14.2 q ha-1) as well as oil (43.2 %) and protein contents (21.82 %) were recorded in rapeseed which received comparatively higher doses of S and Zn along with FYM and RDF.
