dc.description.abstractThe study was conducted based on secondary data collected from AICRP on Agro-forestry, UAS Dharwad. The objective of the study was to predict the yield of soybean in Simarouba glauca based agroforestry system in relation to weather parameters and to fit growth curves and models for Simarouba tree species. The data pertaining to growth parameters that is height (m), DBH (cm), crown area (m2/plant) and yield of associated crop soybean (kg/ha) for ten years at different spacing’s viz. 5x3, 5x4 and 5x5 meters for Kali and Gauri varieties of Simarouba glauca were collected. The various statistical tools viz. correlation, multiple and stepwise regression were carried out to know influence of tree component on yield of soybean at different spacing’s in relation to weather parameters. The result revealed that, the yield of soybean showed decreasing trend as increase in the crown area. Different nonlinear models were tried for predicting height and diameter growth of Kali and Gauri varieties of Simarouba glauca. Among all models studied, MMF model was best fit followed by Logistic and Weibull models based on highest R2 value and least standard error for predicting height and diameter growth of Simarouba glauca at different spacing’s. The highest B:C ratio for soybean yield with Simarouba glauca was observed in 5m x 5m spacing followed by 5m x 4m and 5m x 3m spacing. This revealed that the yield of the soybean in Simarouba glauca at 5m x 5m spacing is profitable almost up to eight years whereas in case of 5m x 4m spacing and 5m x 3m spacing it is profitable up to three years only.en_US
