RÉSUMÉ
Integrated nutrient management (INM) is a holistic approach that involves the application of organic and inorganic fertilizers to improve soil health and crop productivity. The research study was conducted to demonstrate the effective use of INM on soil health in Green gram. We used a randomized block design (RBD) with four levels of poultry manure @ 0, 50, 75 and 100% ha-1, four levels of nitrogen, phosphorous and potassium@ 0, 50, 75 and 100% ha-1 and rhizobium seed treatment. The revealed that treatment T9 (N20P40K40 kg ha-1 + PM @ 5 t ha-1 and Rhi @ 200g 10 kg-1 Seed) resulted in a slight change in soil pH 6.82, electrical conductivity (EC) 0.198 dS m-1. In post-harvest soil of fertilizers observations showed significant increase in pore space 49.20 %, water holding capacity 47.59 %, organic carbon 0.49 %, and available N 334.23 kg ha-1, P 34.58 kg ha-1, K 202.83 kg ha-1. The increase in NPK was found to be significant (P<0.05) among other treatments in Green gram cultivation and soil quality improvement. The application of N P K with poultry manure was a magnificent source of fertilization.
RÉSUMÉ
An experiment was conducted during in Zaid season (March 2022-June 2022) to study the “effect of different levels of NPK and Zinc on soil health in black gram (Vigna mungo L.)” on central research farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. A randomized block design was used to set up the experiment, with three levels of NPK (0%, 50%, and 100% NPK) and three levels of zinc (0%, 50%, and 100% zinc). The outcome demonstrates that inorganic fertilizer application had a non-significant effect on soil physical-chemical parameters (BD, PD, pH, EC and OC) and significant increase in pore space, water holding capacity, available nitrogen, phosphorus, potassium and zinc in treatment T9 [NPK at 100% + zinc at 100%] than other treatments.

RÉSUMÉ
Today, with the advancement of environment pollution and health that is obtained from the improper use of inorganic fertilizer, production and use of organic fertilizer is considered as an important approach in the field of soil science in the world’s interest to investors. A research was conducted during Zaid season 2022 on central research farm of department of soil science and agricultural chemistry, (NAI) SHUATS, Prayagraj. Field trial was designed on Randomized Block Design with three replications and nine treatments. It may be concluded from the trial that the different level of NPK and FYM in the experiment gave the highest value. The best results were obtained with T9 treatment which included (N20P40K40 kg ha-1 + FYM10 t ha-1). This treatment resulted in the maximum plants height with the most leaves, no. of clusters plant-1, no. of pod cluster-1, no of pod plant-1, length of pod (cm) and highest pod yield. In contrast, the control treatment (T1) had the lowest results in all categories. The available NPK and FYM with the treatment combination of T9 (N20P40K40 kg ha-1 + FYM10 t ha-1) was found to be the best for the improvement of growth and yield of cluster bean. Therefore, farmers of Prayagraj region can adopt this combination to give the highest yield of cluster bean.

A study was done to evaluate the physical and chemical characteristics of soils in 2022–23 in several Kandhmal districts of Odisha. The primary goals of this study were to investigate the physico-chemical characteristics of soil at various depths. To determine the availability of macronutrients in soil samples from Udayagiri, Raikia, and Tikabali blocks in Kandhmal District, Odisha, and to provide an assessment, 9 sampling locations were chosen. The depths at which soil samples were taken were 0–15, 15–30 and 30–45 cm, respectively. The soil colour (dry condition) varied from brownish yellow to yellow. The soil colour (wet condition) varied from dark reddish brown to dark brown. On practically every site, sand and loam dominated the soil texture. Bulk density varied between 1.01 and 1.49 Mg/m3). The range of the particle density was 2.14 to 2.52 Mg m-3. Pore space varied between 47.64 and 41.11%. The range of the water-retaining capacity was 45.17 to 39.17%. The pH of the soil was 5.01 to 6.15, which indicates that it is moderately acidic. Between 0.17 and 0.41 dS m-1, the electrical conductivity was found to be The range of the soil's organic carbon was 0.21 to 0.41%. The range of available nitrogen was 134–330 kg ha-1.
