A field experiments on evaluation of weed management practices in scented rice under organic production system was conducted during 2017-18 and 2018-19 at All India Coordinated Research Project on Farming System, Rewa (M.P). The study reveals that weed control efficiency and grain yield of rice were maximum under incorporation of mustard oil cake 5 t/ha+1 HW and two hand weeding at 25 and 50 DAT. The net profit and B:C ratio were maximum under 2 HW at 25 and 50 DAT followed by mulching with locally available weed mulch @ 3 t/ha+1 HW under organic production system which also gave B:C ratio more than 2. Heat use efficiency was maximum 7.94 kg/ha per GDD under incorporation of mustard oil cake @ 5t/ha with one hand weeding followed by 2 HW at 25 and 50 DAT.

Application of inadequate and unbalanced quantity of fertilizer to these crops not only results low crop yield but also deteriorates the soil properties (Sharma et al., 2003). Degradation in soil health has emerged as a major factor responsible for stagnation in agriculture production. The maintenance of

The field experiment entitled "Studies on bio-intensive multiple cropping system module in Kymore Satpura Plateau under irrigated condition" was taken under All India Coordinated Research Project on Farming System, Kuthulia farm of JNKVV, College of Agriculture, Rewa (M.P.) during 2017-18 to 2019-20. The study reveals that rice crop performed better under the residual effect of different cropping system module significantly and grain yield of rice was increased by 2% to 14.83% as compared to existing rice-wheat system. Maximum grain yield of rice 52.79 q/ha was obtained in ricebarley-bajra cropping system followed by 50.68 q/ha in rice-gram+mustard-green manure cropping system. Rice equivalent yield (275.29 q/ha) and gross return (Rs.495520/ha) were obtained in rice-garlic cropping system followed by 149.42 q/ha REY and gross return Rs.268969/ha under rice-potato-green gram cropping system. The net profit Rs.321880/ha was maximum in rice-garlic followed by Rs.192342/ha in rice-potato-green gram cropping system. Benefit cost ratio 3.28 was maximum in rice-berseem followed by 3.19 under rice-gram+mustard-green manure cropping system while rice-pea-green gram and rice-toria-onion gave lower B:C ratio than existing rice-wheat system.

Experimental evidences show that rice-wheat, rice-green manure-barley, rice-gram + mustard-green manure, rice-pea-green gram, rice-potato-green gram, rice-pea + mustardgreen manure, rice-berseem, rice-barley fodder-bajra fodder, rice-garlic and rice-toriaonion have been found effective and
