Background: Blackgram being important crop among pulse is gaining popularity and thus requiring suitable production practices especially under organic farming. In this context, study was proposed with the objective to investigate optimal nutrient management in blackgram by utilizing various sources. Methods: Field experiments were conducted at two different locations spilt plot design. The trea...

Field experiments were undertaken to ascertain the residual effect of organic manures on black gram crop in a rice-blackgram cropping sequence during summer seasons 2017 and 2018 at Thoppur, Thirupparankundram, Madurai. Twelve treatments comprising various sources nutrients (green manure, neem cake, enriched FYM, Panchagavya, tamarind seed powder) randomized block design with three replications...

The trial carried on topic “Response of organic manures and rice residues soil physical health parameters” for the two repeated years, start from winter seasons years 2021-22 at research farm, department science agricultural chemistry. Total 54 samples were taken site different depths i.e., 0-15 cm 15-30 cm. Among nine treatments, during field experimentation, conjunctive use NPK [FYM, vermicom...

Phosphorus in runoff from fields where poultry litter is surface-applied is an environmental concern. We investigated the effect of adding phytase and reducing supplemental P in poultry diets and composting poultry manures, with and without Fe and Al amendments, on P in manures, composts, and runoff. We used four diets: normal (no phytase) with 0.4% supplemental P, normal + phytase, phytase + 0...
