Abstract: A field experiment was planned and carried out with entitled “Effect of soil moisture and agrochemical A field experiment entitled “Effect of green manuring and fly ash on the growth and grain yield of rice (Oryza sativa L.)” was conducted during kharif 2018 at Research Farm, Guru Kashi University, Talwandi Sabo, Bathinda (Punjab). The experiment was laid out in split plot design comprising two green manuring levels viz., control (0 t/ha), and 25 t/ha incorporation in main plots and three fly ash doses viz., control (0 t/ha), 10 and 20 t/ha in sub plot plots. It is clearly concluded that there is a good scope of increasing crop yields through the use of green manuring and fly ash. It is extremely important for sustaining production and improving the fertility of soils. Green manuring significantly increased the plant growth viz., plant height, dry matter and number of tillers/plant and yield attributing characters viz., number of grains/panicle and test weight and seed cotton yield, straw yield and harvest index in rice. Incorporation of green manuring @ 25 t/ha recorded 8.70% more grain yield than control. Fly ash @ 10 t ha^-1 and 20 t ha^-1 resulted in the statistically similar plant growth, yield attributes and grain yield in rice. Fly ash @ 10 t ha^-1 and 20 t ha^-1 recorded 9.40 and 6.75%, respectively higher grain yield than control.
