“…The mulching and nitrogen played a vital role in root development as well as nutritional value of the grains and nitrogen uptake by seeds and stover. Similar results were reported by [16] and Singh et al, (2019) [17].…”

At experimental farm of M. S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi, Odisha, India, an experiment was conducted to know the effect of nitrogen doses and mulching on nutrient status, yield and economics of maize during the rabi season of 2021-22. The hybrid maize seed (Hybrid variety 4226) was sown in a spilt plot design with three levels of mulching in main plot and four doses of nitrogen in sub-plot. The grain yield, nutrient composition of maize seeds and stover, N, P, K status of pre-harvest soil were increased significantly in combination of nitrogen and mulching. Application of straw mulch significantly increased the N content of grain and stover as well as the N uptake by grain and stover as compared to no mulch treatment. It also influenced the protein content of seeds. Application of higher dose of N significantly increased the N content of grain and stover as well as the N uptake by grain and stover over the control and also influenced the NPK status of soil and protein content of the seeds. Maximum values of grain and stover yield (7.26 and 9.21t ha-1 respectively) were recorded from 5 t ha-1mulchand 150% RDN (N:P2O5:K2O = 120:60:60) plot. Whereas this interaction effect (5 t ha-1 and 150% RDN) significantly increased the N content of seeds (1.40 %), stover (0.47 %), and protein content of seeds (8.76 %). After decomposition of straw mulch in soil with additional application of nitrogen increased the available N (195.43 kg ha-1) over low level of nitrogen dose with no mulching. The combined application of mulching @ 5 t ha-1 with 150% RDN resulted highest net return (₹76,365/- ha-1) with maximum B:C ratio (1.29).

“…The organic manures increase the water-holding capacity of the soil, as well as phosphate availability. Organic manures also increased the efficiency of fertilizer application and the soil's microbial and organic carbon content [16][17][18][19]. Organic manure also reduces soil nitrogen losses [20].…”

A field experiment was carried out throughout Zaid season 2022 on the research farm of the Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj, to examine the variations in physicochemical properties of soil and yield of maize, as affected by the levels of NPK and vermicompost in the eastern part of Uttar Pradesh. The soil at the test site was sandy loam in texture and is located at 25024’30’’ North latitude, 81051’10” East longitude, and about 98 meters above sea level. The experiment was designed in a block-based design that was randomly randomized with nine different treatments T1@0%NPK ha-1 + @0%Vermicompost ha-1, T2@0%NPK ha-1 + @50% Vermicompost ha-1, T3 @ 0% NPK ha-1 + @100% Vermicompost ha-1, T4 @ 50% NPK ha-1 +@ 0% Vermicompost ha-1, T5 @50% NPK ha-1 + @50% Vermicompost ha-1 , T6 @50%NPK ha-1 +@100%Vermicompost ha-1 , T7 @ 100% NPK ha-1 +@ 0% Vermicompost ha-1 , T8 @ 100% NPK ha-1 +@ 50% Vermicompost ha-1 , T9 @ 100%NPK ha-1+ @100% Vermicompost ha-1. which were replicated thrice. The soil's physico-chemical characteristics before sowing and following crop harvest were assessed using standard procedures. Bulk density, Particle density, percent pore space and water holding capacity Was determined by (Muthuval et al) pH, Ec and organic carbon was determined by Digital pH meter, Digital EC meter and Walkley and Black method respectively. Available N, P, K was determined by Kjeldhal Method, Colorimetric method and Flame photometric method respectively. The experimental findings showed that the Bulk density, percent of pore space, capacity for holding water, Ec, organic carbon and available N, P, K of soil were found to be significant at various quantities that included NPK and Vermicompost. Post-harvest soil physico-chemical properties (Water holding capacity, percent pore space, Electrical conductivity, organic carbon, Available nitrogen, phosphorus and potassium) were maximum underT9(100%NPK ha-1+ 100% Vermicompost ha-1) and followed by T8(100%NPK ha-1+ 50% Vermicompost ha-1). It was also observed that the soil's Bulk and particle density were improved under T9(100%NPK ha-1+ 100% Vermicompost ha-1) when compared with other control treatments and treatments combinations. Bulk density gradually decreased with an increased dose of NPK and vermicompost. So, integrating inorganic and organic fertilizers has resulted in improved physico-chemical properties compared to the sole use of 100% RDF.
