Therefore, a field experiment was conducted for two years (2017–18 and 2018–19) to determine the beneficial effects of BP in reducing nutrient stress and yield enhancement in turmeric. The study was laid out in a split-plot design with each of four levels of nutrients (control, 50%, 75%, and 100% of Recommended Dose of Nutrients; RDN) and BP (0, 2.5, 5.0, and 7.5 kg ha–1). Results indicated that BP application (7.5 kg ha–1) significantly improved the soil moisture content (40.31%) and microbial colonization (total microbes, N fixers, and P solubilizers). As a result, combined application BP with either 75% or 100% of RDN enhanced the photosynthesis (22.95–24.50 μmol m−2 s−1) and lowered the canopy temperature (24.47–24.67°C) of turmeric. Thus, higher yield (7.05–7.82 t ha−1) and partial factor productivity were achieved. Supplementing BP with 100% RDN enhances the turmeric yield by up to 29–49% over 100% RDN alone. Therefore, biopolymer maintains the equivalent turmeric yield of 100% RDN even at 25–50% less nutrients in the nutrient-poor soils of semi-arid Tropics.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2645 - 2662"},"PeriodicalIF":2.4,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48018590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PRDI decreased the soil available P content and stock but had no effect on the total P content and stock, which demonstrates that effect of PRDI on crop available soil P was different when different P forms were used to estimate crop available soil P. This study also showed that the variation in the coefficient was below 3% between soil P (available or total P) contents and soil P stocks, indicating that soil P contents and stocks were similar when estimating alfalfa available soil P under PRDI conditions.

A greenhouse pot experiment was set up to compare three commercial organo-mineral fertiliser formulations (NPK, NP and K) with the corresponding formulations containing a slow-pyrolysis wood biochar (NPK+B, NP+B and K+B) (6 replications each). Nutrient leaching as well as crop growth and nutrient uptake was monitored using barley as model species. Nutrient leaching was slowed down in the NPK+B compared to the NPK fertiliser. The most responsive ions were nitrate and potassium, whose leaching during the two first weeks was reduced by 28% and 22%, respectively, while this trend reversed from the third week on. One plausible explanation would be a microbial nutrient immobilisation mediated by the concurrent NPK and biochar habitat provision. NPK+B significantly enhanced barley straw biomass (23.43% increase respect to NPK), whereas all the biochar-based fertilisers showed increases in nutrient content and export (involving potassium, sulphur, calcium and manganese), possibly indicating that biochar acted as a nutrient source.
