Frontiers in Sustainable Food Systems, Journal Year: 2023, Volume and Issue: 7

Published: March 2, 2023

Environmental pollution, resource dwindling, and soil degradation questioned the sustainability of contemporary agricultural production systems. Organic farming is advocated as a sustainable solution for ensuring food security without compromising environmental sustainability. However, poor farm productivity quizzed organic Hence, field study was carried out in Sikkim region Indian Himalayas to assess efficacy conservation-effective tilling diversified cropping on system productivity, profitability, quality, nutrient balance farming. Three tillage systems, namely, (i) conventional (CT), (ii) reduced (RT), (iii) zero (ZT), four maize based systems (maize–black gram–toria, maize–black gram–buckwheat, maize–rajmash–toria, maize–rajmash–buckwheat) were tested using three times replicated split-plot design. The ZT recorded 13.5 3.5% higher over CT RT, respectively. Of maize–rajmash–buckwheat maximum (13.99 Mg ha −1 ) net returns (3,141 US$ followed by gram–buckwheat system. Among practices, significantly high eco-efficiency index (EEI; 1.55 per kg CO 2 -eq emission) lowest greenhouse gas intensity (GHGI; 0.15 production). maize-rajmash-buckwheat registered GHGI (0.14 production) highest EEI (1.47 emission). Concerning balance, after cycles, under available N (340.0 ), P (16.6 K (337.3 at 0–10 cm depth. Similarly, had bio-available NPK. Thus, suggests that cultivation gram/rajmash–buckwheat and/or RT would increase fertility with minimum Eastern Himalayan India.

Integrating conservation agriculture with intensive crop diversification in the maize-based organic system: Impact on sustaining food and nutritional security

Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: March 14, 2023

Developing an intensive sustainable model and feeding a rising population are worldwide challenges. The task is much more daunting in the North Eastern Himalayas, where, low productive maize (Zea mays)- fallow main production system upland. To increase farm productivity, nutritional security, energy dietary returns while maintaining environmental sustainability economic viability, short-duration crops must be included maize-fallow system.A field study was conducted sandy clay loam soil with randomized complete block design three replications for continuous years (2018-2021) under organic management two crop practices, viz., (i) conservation agriculture (ii) conventional agriculture, six diversification options, maize-sweet corn mays saccharata)-vegetable pea (Pisum sativa) (M-SC-VP), corn-mustard (Brassica juncea) (M-SC-M), (iii) corn-lentil (Lens culinaris) (M-SC-L), (iv) corn-vegetable broad bean (Vicia faba) (M-SC-VB), (v) (local)-vegetable (M-VP), (vi) (local)-fallow (M-F).The results showed that, average productivity 5.3% lower than agriculture. System carbohydrate, protein, fat, fiber, were ~6.9, 6.8, 7.8, 6.7, 7%, higher respectively. Similarly, macronutrients (Ca, Mg, P, K) micronutrients yield (Fe, Mn, Zn, Cu) were, 5.2-8% 6.9-7.4% On average, over years, M-SC-VP/M-SC-VB rotation had (158%), efficiency (157%), net (benefit-cost ratio) (44%), (16.6%) local maize-vegetable system. improved security by improving Ca, K, Fe, Cu 35.5-135.7% M-VP system.Conservation significantly (p < 0.05) carbohydrate yield, protein fat fiber production. It concluded that health performed better maize-based cropping systems. Overall indicate can potentially calorie consumption profitability.

Organic farming is emerging as an alternative sustainable agri-food system globally both in developed and developing nations. In India, organic offers a promising to conventional may contribute significantly mitigate climate change by improving soil health, fostering biodiversity, enhancing carbon sequestration. Lower yields, higher production costs market access barriers, particularly for smallholder farmers are significant challenges scaling up of practices on small farmers’ fields. However, growing opportunities premium prices products, reduced input over time improved resilience need be addressed. This paper examines global national trends, highlighting India’s position major player the food ecosystem with area, products technologies. It also delves into productivity profitability systems, acknowledging trade- offs between environmental benefits economic costs.

Introduction Over the years, smallholder farmers have faced more vulnerability to risk and uncertainty in India due their dependence on cereal crops. One way reduce this is through diversified agriculture, integrating different practices for efficient resource utilization, adopting a farming systems approach. An integrated system (IFS) one such technique that provides year-round income from components of enterprises. However, decision adopt IFS may be determined by several characteristics farmers, which needs delineated impact analysis harness benefits Methods This study analyzes economic effects assesses determinants, as well dietary diversity patterns two states southern India, i.e., Kerala Tamil Nadu.
