Abstract:

The experiment on bund plantation of Eucalyptus teretricornis and its effect on paddy were studied as bund Agroforestry system on growth of paddy and its yield at different distances from the base of the trees, the effect of crown shade on growth and productivity was also observed this experiment laid on farmer's field in the Village Khudmuda, Durg district (CG), during the year 2019-20 in Kharif season.

The Eucalyptus was planted on field bund in North - South direction of the field. The experiment was carried out in a Randomized Block Design (RBD) with one control plot. The trees were selected having different DBH and crown width range from 21.33–27.38 cm and 6-8 m, respectively. The results showed that the bund based Ago-forestry system reveled adverse affect on growth and yield of paddy which varies in different dbh and crown width of the tree with distance from the tree line. Due to increasing crown width and closeness from the tree, the growth of rice ie. Number of hills per quadrate and number of tillers per quadrate of Paddy reduced drastically. The maximum number of tillers at different distances from the line of the tree was reported at a control plot (99.12) from tree 3 and the minimum number of tillers found at the nearest distance, ie 1-3 m from the tree line. The minimum reduction in grain weight with inflorescence quadrate (5.67 gm) was observed at a control plot from tree 3 and the maximum decreased (1.22) was observed at a distance of 1 m from tree 1, in comparison with all other distances. The maximum reduction was observed at the different distances from the line of the tree at a distance of 1-5 m from the tree line, which decreased successively with the rise in distance from the tree line, which indicates that inflorescence / quadrate grain weight (g) was substantially increased due to decreased crown width and increased distances from the tree line. The number of tillers of paddy was influenced by various aspects at various distances from the tree line. The maximum plant height was found (113.88 cm) at a control plot from the base of the tree 3 and the minimum Plant height was found to be lower (81.00 cm) at a distance of 1 m from tree 1. The tillers were substantially reduced from the tree line to a control plot. The highest (98.53 percent) harvest index percent was found on the 1 m distance tree 1, followed by tree 2 (97.47 percent), at a distance of 1 m from the tree line and the lowest at a 1 m distance from the tree line at tree 2 (97.27). Due to higher bole dbh and crown width of the Eucalyptus tree and decreasing distance from the tree line, the adverse effect of the tree line on harvest index percent was recorded. Thus results of present study indicates that highest reduction in the yield was observed near the tree line ie1-5 m the decrease followed the order, tree3> tree 2>, and tree at all distances from the line of the tree. Thus it can be concluded that minimum crown width and increasing distance from the tree line of Eucalyptus had less effect on the growth and yield of rice as compared to the trees with maximum crown width and closeness with tree or tree line.
