Abstract
A study entitled ―Nutrient availability in soil, their uptake, growth and yield of mustard under INM approach in light texture soil‖ was carried out during 2019-20 & 2020-21, at CRC farm, SVPUAT campus, Meerut. The experimental field was uniform and leveled, sandy loam in texture, low in available nitrogen (219.3 kg ha-1), medium in available phosphorus (16.9 kg ha-1), potassium (244.3 kg ha-1), sulphur (14.3 kg ha-1), zinc (0.78 mg kg-1) and iron (9.42 mg kg-1) with slightly alkaline in reaction (pH 7.82). The experiment was carried out in Randomized Block Design with four replications and 10 treatments. The treatments comprised of T1 (control), T2 RDF (-S), T3 RDF (+S), T4 125% RDF (+S), T5 100% RDF (-S) + 4 ton FYM, T6 100% RDF (-S) + 1.25 ton Vermicompost, T7 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost, T8 75% RDF (-S) + 4 ton FYM, T9 75% RDF + 1.25 ton Vermicompost and T10 75% RDF + 2 ton FYM + 0.6 ton Vermicompost. Treatments effects of nutrient management were evaluated in terms of growth and yield of mustard. The results also revealed that among the different integrated nutrient management treatments the highest grain yield (24.3 & 25.7 q ha-1) was obtained under 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost which were at par (23.7 & 24.4 q ha-1) with the application of 75% RDF + 2 ton FYM + 0.6 ton Vermicompost and (22.8 & 23.0 q ha-1) 100% RDF (-S) + 1.25 ton Vermicompost during both the years. The highest total NPK, S, zinc and iron content and uptake by grain and straw found with 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost was at par with 75% RDF + 2 ton FYM + 0.6 ton Vermicompost and 100% RDF (-S) + 1.25 ton Vermicompost. The results revealed that the highest net monetary return (₹ 98935 & 115085 ha-1) and B: C ratio (3.47 & 3.88) was obtained with 100% RDF (-S) + 2 ton FYM + 0.6 ton Vermicompost, which was found at par with 75% RDF + 2 ton FYM + 0.6 ton Vermicompost during both the years. On the basis of two year experiment it can be concluded that application of 75% RDF + 2-ton FYM + 0.6 ton Vermicompost may be recommended for achieving higher yield and net return from mustard crop and maintaining soil sustainability.
