Background: Increasing demands of food, depleting land, degrading land resources and changing climate are some of the important factors driving the cropping systems of any agro-ecological zone in the world. Cropping systems have been traditionally structured to maximize crop yields. Now, there is a strong need to design cropping systems which take into consideration the emerging social, economical and ecological or environmental concerns. Legumes can provide opportunities for increased productivity to be sustained because of their adaptability to various cropping patterns and ability to fix nitrogen. Legume-based crop rotation helps to conserve organic matter, maximise soil nitrogen, balance soil nutrients, maintain soil physical properties and break soil-borne disease cycles. Moreover, with increasing fertilizer prices and emphasis of the government for doubling the farmer’s income by reducing cost of cultivation, the current trend is to explore the possibility of supplementing chemical fertilizer with the organic ones, more particularly organic manures and bio-fertilizer of microbial origin. The current study is aimed to increase small and marginal farmer’s income and to reduce cost of cultivation through legume based vegetable cropping systems and to find out best farming practices. Methods: Field experiments were conducted at Organic Farm Holta, Department of Organic Agriculture and Natural farming, CSK HPKV, Palampur (H.P.) during kharif and rabi seasons of 2018-19 and 2019-20 on silty clay loam soil to study the performance of different farming practices in legume based cropping system under mid- hills of H.P. Himalayas. The experiment was laid out under Split plot design with three replications comprising of three sequences in legume vegetable-based cropping systems i.e., “Soybean-Onion”, “Okra-Pea” and “Mash-Garlic” under different farming practices i.e., Organic farming, Natural farming, Inorganic and Integrated farming practices. For comparison of different crops soybean equivalent yield and pea equivalent yields were calculated in kharif and rabi seasons, respectively.
Result: In kharif seasons okra crop attained highest soybean equivalent yield followed by soybean and mash crop. In rabi seasons garlic crop attained highest pea grain equivalent yield followed by onion and pea crop. During both kharif seasons organic farming practices attained highest yield and was at par with integrated farming practices. Significantly highest yield was attained from integrated farming practices and was at par with organic farming practices in both rabi seasons. Highest net returns, net returns per rupee attained was in inorganic farming system. Highest cost of cultivation was found in organic farming practices.
