“…Yield penalties of no-till depended on crop residue return and crop rotation and were larger in tropical than temperate regions, and tended to decrease with an increase in the duration of no-till [22,111]. The South-Asian study was probably the most integrated one, as it examined effect sizes of crop yield, water use, soil organic C sequestration, emissions of CO 2 , CH 4 , and N 2 O, and economic costs [112]. The cost of production was significantly lower under no-till than under conventional tillage in all the selected crops, and the net economic returns increased by 5 to 32%.…”

Coherent improvements in crop varieties and crop husbandry and soil management practices are needed to increase global crop production in a sustainable manner. However, these practices are often discussed separately, and as a result there is little overview. Here, we present a database and synthesis of 154 meta-analysis studies related to ten main crop husbandry and soil management practices, including crop type and rotations, tillage, drainage, nutrient management, irrigation and fertigation, weed management, pest management, crop residue management, mechanization and technology, and landscape management. Most meta-analysis studies were related to tillage (55), followed by crop type and rotations (32), nutrient management (25), crop residue management (19), and irrigation and fertigation (18). Few studies were related to landscape management (6) and mechanization and technology (2). In terms of outcome, studies focused on crop yield and quality (81), soil quality (73), and environmental impacts (56), and little on economic effects (7) or resource use efficiency (24). Reported effects of alternative practices, relative to conventional practice, were positive in general. Effect sizes were relatively large for environmental effects (nutrient leaching, greenhouse gas emissions), and small for soil quality (except for soil life) and crop yield. Together, meta-analysis studies indicate that there is large scope for increasing cropland productivity and minimizing environmental impacts. A roadmap is provided for integration and optimization of all ten practices, and recommendations are formulated to address the gaps in meta-analysis studies.

“…Jat et al 38 and Kiran Kumara et al 39 argue that farmers and policymakers do not understand how CA can reverse the process of soil degradation and thereby accelerate sustainable agriculture so that knowledge gap and institutional barriers are the challenges to CA development. 40 Meanwhile, international and government supports are essential for CA development to increase local production and adaptation of equipment for local equipment, economic conditions, and skill levels of farmers.…”

Different countries face diverse challenges for Conservation Agriculture (CA) development. The main purpose of this study was to examine the challenges of applying CA in Iran from the perspective of experts and farmers. A focus group method was used to investigate the challenges. The research sample consisting of farmers and experts of CA in different provinces includes those 19 experts and 15 farmers. Inductive content analysis and coding (open, axial, and selective coding) were employed to analyze the farmers’ and experts’ discussions. The findings showed that the challenges of applying CA in the studied provinces could be divided into 6 general categories: institutional-infrastructure (7 concepts), economic (5 concepts), training-research (2 concepts), environmental (4 concepts), mechanization (2 concepts), and cognitive (2 concepts) challenges. The economic and institutional-infrastructure challenges were the most frequent related to applying CA. It can be concluded that to solve the challenges of applying CA, it is necessary to link various sectors of government (the Ministry of Agriculture), education and research (Agricultural Research, Education and Extension Organization), and industry together. But farmers themselves are also a major contributor to meet the challenges of CA development through participation in planning CA project and training-extension programs. Therefore, farmers’ communities should also pave the way for a transition from conventional agriculture to CA with their participation.

“…Currently, CA is practiced on all continents, in a range of agro-ecosystems, and on farms of various sizes (Friedrich et al, 2012). The adoption of CA practices resulted in better economic and productive returns as compared to traditional agricultural practices along with significant environmental benefits (Tambo & Mockshell, 2018;Kiran Kumara et al, 2020).…”

Conservation agriculture (CA) is the combination of environmental management, modernand scientific agriculture, which employs farmers’ ability to utilize, innovate, and adapt tochanging situations, as well as their holistic acceptance of knowledge along with ensuringsustainability. Farm-level adoption of CA is related to reduced labour and agricultural inputs,more consistent yields, and increased soil nutrient exchange capacity. A good quality landyields good results to everyone, confers good health on the entire family, and causes growthof money, cattle, and grain. The present study depicts hard evidences by identifying markervariables impacting income augmentation through conservation agriculture. A score of 50farmers has been selected from two blocks of Cooch Behar district of West Bengal, bynon-probability snowballing sampling techniques with a total of eighteen independentvariables along with income from major crop is used as the dependent variable through astructured interview schedule. A basket of multivariate analytical techniques has been appliedalong with Artificial Neural Network (ANN) as well. The results depict that a blend ofdiversified farming and farming experiences in CA contributed immensely to scale up incomefrom conservation agriculture approaches.
