ABSTRACT

This experiment was conducted to determine the effect of tree species associations with different orientations grown as intercrop with rice on the incidence of major rice diseases (Bacterial leaf blight, Blast, Sheath blight and Brown spot). Jhau-rice association developed least incidence of four major diseases and the highest disease severity was recorded in Sissoo-rice association. The highest and lowest severity were recorded in O3 and O0, respectively. Out of five tree-rice associations highest yield (4.345 t ha -1) was obtained in case of Jhau-rice (T2) association and lowest yield (2.550 t ha -1) was recorded in Sissoo-rice (T5) association. Regarding different orientations, The highest yield (5.486 t ha -1) was obtained from open field (O0-orientation) and the lowest yield (1.522 t ha -1) was recorded in North-1.5 meter from the tree base (O3).
