ABSTRACT: The soils of Ghana vary with location due to difference in parent material and climate with low productivity. Biochar is increasingly proposed as an amendment that can improve soil productivity but its effectiveness is texture dependence. Therefore, this study was carried out to find out if biochar application is effective for all soil textures in northern Ghana. To achieve that soil data (texture, organic carbon, soil depth and bulk density) were obtained for 35 locations (cultivated and uncultivated) were collected across the northern regions. A validated crop model......

ABSTRACT: The culture was conducted in three ponds, each sized 0.7, 0.7, and 0.4 hectares in Pucchakurthivaari palem, Andhrapradesh, and an intensive culture system was selected under bore water circumstances. Sy aqua seed was collected from Manjunaadha hatcheries; the L. vannamei seed was provided from the CAA-certified Ulavapaadu village in the Prakasam district, Andhrapradesh. The stocking densities of L.vannamei PL10 (post larvae) were calculated using three samples, each of which had 23, 37, and 28 species/m2 and 59, 60, and 51% survival rates. The......
