Abstract:
In Kharif season an experiment was conducted at Kuthulia farm of JNKVV, Rewa (M.P.). The soil of experimental field was silty clay loam in texture; the rice (Oryza sativa L.) crop was transplanted at planting geometry of 20 cmx 15 cm in which two seedlings per hill was transplanted. The fertilizer dose for rice was 120 kg N, 60 kg P₂O₅ and 40 kg K₂O/ha under all the cropping systems. The number of tillers/hill of rice was recorded at 25 DAT, 50 DAT and 75 DAT (at harvest) stage of rice and maximum tillers/hill of rice were noted in berseem-rice followed by mustard-green manure-rice, potato-wheat-rice and garlic-rice. The biomass yield 153.96 q/ha was maximum in mustard-green manure-rice followed by 148.27 q/ha in toria-onion-rice and 147.65 q/ha in potato-wheat-rice these cropping system gave more biomass yield by 15.92 percent to 22.85 percent as compared to existing wheat-rice system. The organic carbon increased by 12.5 to 17.85 percent. The intensity of weed varied from 18.45 to 43.01 weeds/m² under different cropping systems. The maximum harvest index was 37.36 percent in berseem-rice.
