Soil fertility under Asana (Bridelia Retusa) based agroforestry systems in lateritic soil of Konkan

Abstract

An experimental study was conducted during 2019-20 at the Research Farm of AICRP on Agroforestry, Dr. BSKKV, Dapoli, Maharashtra. The results emerged out indicated that, significantly high soil fertility of Asana based agroforestry were recorded by T₆>T₅>T₇ than other. The soil fertility status was noted slightly improvement in pH (5.94 to 5.97) and EC (0.232 to 0.254 dSm^-1) by T₆ during the years of 2019 and 2020. The maximum organic carbon (2.18 to 2.27 %), N (343.66 kg ha^-1), and (351.33 kg ha^-1), available P₂O₅ (22.30 to 25.20 kg ha^-1) and available K₂O (439.08 to 455.84 kg ha^-1) were recorded in T₆ in the year of 2019 and 2020, respectively.  Overall, it can be concluded that the improving soil fertility were recorded significantly by T₆>T₅>T₇ than other, it may be due to presence of high amount biomass contribution and addition organic matter in the soil.  Thus, T₆ –Asana + Jam is the best treatment under asana based agroforestry systems seem to be increased the soil fertility in lateritic soils of Konkan.
