Abstract:
An experiment was conducted at Zonal Agricultural and Horticultural Research Station, Babbur Farm, Hiriyur during the year 2021-2022. Agroforestry is becoming more significant in light of the increased need for wood and the accessibility of farmland. The main area for agroforestry consideration is the creation of a suitable tree crop spacing combination and productivity evaluation. The present field experiment was conducted to assess growth and yield performance of horse gram under three spacing i.e., 4 m × 1 m, 4 m × 2 m, and 4 m × 3 m of Melia dubia and with sole crops as horsegram. The experiment consists of four treatments with five replications in RCBD design treatments T1- horse gram in 4 m × 1 m, T2- horse gram in 4 m × 2 m, T3- horse gram in 4 m × 3 m and T4- sole horse gram. Horse gram growth parameters were recorded at 30 DAS, 60 DAS and at harvest and yield parameters were estimated. Results revealed that there was a significant difference between horse gram growth parameters i.e., plant height, number of branches and dry matter production at 30 DAS, 60 DAS and at harvest. The horse gram yield parameters were ranked as T4 > T3 > T2 > T1 with significant difference among T1, T2, T3 and T4. The highest yield of horse gram was obtained in T4 (1220.02 Kg/ha) followed by T3 (931.4 Kg/ha), T2 (667 Kg/ha) and T1 (529 Kg/ha). The horse gram growth and yield increases with increasing spacing of Melia dubia and relatively higher in sole horse gram plot. The shade impact that trees have on crops may be the reason of the decline in yield with decreasing spacing. However, the long term benefit of trees wood accumulation fetched more economic returns in the future.
