Effect of integrated nutrient and agronomic management on growth, productivity, nutrient uptake and soil residual fertility status of soybean

Abstract

A field experiment on soybean was conducted at the regional research farm of the Punjab Agricultural University, Naraingarh (Distt. Fateh Garh Sahib) for three years under irrigated conditions for productivity enhancement through integrated nutrient and other agronomic interventions. There were twelve treatments comprising different levels of N, P, K, FYM and agronomic management practices. The results revealed that soybean significantly responded to the application of N, P, K and FYM. Maximum yield was recorded in the treatment where FYM was applied with NPK and resulted in an increase of 10.8 per cent over NPK alone. Application of additional 30 kg N ha -1 at pre-flowering or at pod initiation did not significantly enhance the yield over the basal dose of NP applied at sowing. Application of 4 tonnes wheat straw mulch + 30 kg N +60 kg P 2 O 5 and 30 kg N + 60 kg P 2 O 5 ha -1 showed similar effect on seed yield of soybean. No statistical difference in soybean yield was observed in the conventional flat and bed sowing treatments. Pre-emergence application of pendimethaline @ 1.5 l ha -1 along with one hand weeding at 40 days after sowing (DAS) and two hand weeding at 20 and 40 DAS were equally effective for weed control and in influencing the soybean yield. The application of N, P, K and FYM, in different treatments, treatment with Bradyrhizobium japonicum and sowing on beds all significantly improved the N, P and K uptake by soybean over control. Application of FYM to soybean resulted in maximum nutrient uptake by soybean. After three years a significant improvement in soil organic carbon, available N, P and K was observed in all treatments over control.

Impact of Integrated Nutrient Management Practices on Soil Health Parameters and Yield Attributes of Soybean (Glycine max L.) var. JS-9560 in Inceptisol of Alluvial Soil, District Prayagraj, Uttar Pradesh

“…The detail analysis of soil parameters pre and post harvest of soil analysis show on Table 3 , Potassium 206.77 kg ha -1 and sulphur 19.3 mg kg -1 found in T 1 control due to the adding of vermicompost influence the microbial activity of soil, increases soil organic carbon and availability of NPK and sulphur. The similar results was reported by [20,12].…”

Influence of Low Cost Natural Farming, Organic Farming and Conventional Farming on Performance of Wheat and Chickpea

“…Higher yield of chickpea was might be due to beneficial effect of organic manures which increased the availability of nutrients considerably resulting in improvement of nodule development, energy transformation, metabolic process and root growth causing more dry matter production and number of nodules (Chaturvedi et al, 2010). These finding are corroborating with results of Baskar et al (2017), Chaudhary et al (2017), Patel et al (2018), Singh et al (2018), Pradeep et al (2018) and Sikka et al (2018).…”

Bioactivation of Legacy Phosphorus in Calcareous Soil and its Impact on Maize Yield

“…Their P uptake was calculated and depicted in Fig 3 . The application of farmyard manure and humic acid with a 100% soil test dose of P (T 3 ) showed a higher grain yield (6613 kg ha -1 ) with P uptake of 9.98 kg ha -1 and stover yield (9814 kg ha -1 ) with P uptake of 14.67 kg ha -1 , which was statistically comparable with T 6 (FYM+HA with 75% soil test dose of P). Similar results were observed by Sikka et al (2018). The FYM application with a full and reduced dose of P fertilizer showed a similar yield, biomass production and P uptake.…”
