“…A recent study by Aryal et al . () in the same study area found that farmers mostly practice minimum tillage in the laser‐leveled plots since it is easy to operate zero tillage seed drill. Hence, unless we analyze this effect, it will not be understood that unavailability of laser land leveling can be one of the major factors limiting the adoption of minimum tillage.…”

“…This study focuses on five CSA practices that are among the key practices promoted by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CRP CCAFS) in south Asia. These CSA practices are found to have clear economic as well as climate change adaptation and/or mitigation benefits (for example, see Aryal et al ., , ; Erenstein et al ., ; Khatri‐Chhetri et al ., ; Sapkota et al ., ). According to CCAFS, CSA refers to those practices that help climate change adaptation, GHG mitigation and food security (for details see Aggarwal et al ., ; http://www.ccafs.cgiar.org).…”

Climate change poses a major threat to agricultural production and food security in India, and climate‐smart agriculture (CSA) is crucial in addressing the potential impacts. Using survey data from 1,267 farm households in 25 villages from Bihar and Haryana in the Indo‐Gangetic Plains, this study analyzes the factors that determine the probability and level of adoption of multiple CSA practices, including seeds of stress‐tolerant varieties, minimum tillage, laser land leveling, site‐specific nutrient management and crop diversification. We applied a multivariate probit model for the simultaneous multiple adoption decisions, and ordered probit models for assessing the factors affecting the level of adoption. The adoption of the various CSA practices is interrelated, whereas several factors, including household characteristics, plot characteristics, market access and major climate risks are found to affect the probability and level of CSA adoption. Climate‐smart agriculture (CSA) adoption and its intensity also vary significantly between eastern Bihar, which is relatively poor and densely populated, and north‐western Haryana. Engaging multiple stakeholders such as farmers, agricultural institutions, agricultural service providers and concerned government departments at the local level is crucial for the large‐scale uptake of CSA. The study, therefore, calls for agricultural policy reforms so that most of the issues related to the uptake of CSA can be adequately addressed.

“…Zero tillage, mainly a mitigation strategy, not only sequesters carbon in the soil but also prevents soil degradation, maintains the nutrient level of the soil, improves soil quality, and ultimately enhances crop productivity and yield (Lal 2004). A recent study in India shows that conservation agriculture-based wheat production systems cope better with rainfall variability compared to the conventional tillage-based system (Aryal et al 2016a, b). Similarly, rice management (direct-seeded rice) can be used to overcome a water crisis, but with high labor costs (Farooq et al 2011).…”

Agriculture in South Asia is highly vulnerable to climate change due to increasing variability in rainfall and rising temperatures leading to the incidence of extreme climatic events such as floods, droughts, heat/cold waves, and storms. Agriculture sector also contributes to the causes of climate change through the emission of greenhouse gasses (GHGs). Hence, adaptation-led mitigation measures are required to sustain agricultural productivity, farm income and reduce GHG emissions wherever possible. This study presents a systematic review of agriculture emission reduction opportunities with a particular focus on agricultural production systems in South Asia. Our review indicates that the adoption of better soil, water, nutrient management practices, and technologies has enormous potential to reduce GHG emissions from agriculture, thereby contributing to the mitigation of climate change. Many existing practices and technologies have the potential to improve both adaptation and mitigation in agriculture which can significantly contribute to complying with nationally determined contributions (NDCs) of South Asian countries. However, barriers to the adoption of GHG mitigating agricultural practices, mainly the financial and institutional barriers, need to be appropriately addressed to achieve the desired level of mitigation.

“…Previous studies on tillage practices, a crop management practice, suggest that optimization of tillage practice alters the dynamic and complex soil in physical, chemical and biological properties [9]- [15]. Proponents of conventional tillage (CT) and zero tillage (ZT) agree on the values of one over the other for crop yield variation across locations and cropping systems [16]- [21]. Understanding interactions among genotype, environment and crop management are important in planning key farm decisions including genotype selection, sustainable farm management and economic planning.…”

The objectives of the study were as follows: 1) to evaluate the GxExM for wheat genotypes; 2) to predict yield performance and identify high stable wheat genotypes in different management practices; and 3) to make genotype-specific management and high performing genotype recommendations within and across agro-ecological regions. A diverse set of twenty-one genotypes was evaluated over three years (2012, 2013 and 2014) under two levels of crop management practices (CT and ZT) across three agro-ecological regions (BR, MP and PB) of India in replicated trials. Data were analyzed with SASGxE and RGxE programs using SAS and R programming languages, respectively. Across and within a location(s), the pattern of GxExM and GxMxY interactions (respectively) among univariate and multivariate stability statistics, grouping of genotypes in divisive clusters and estimates (with a prediction interval) of genotype varied in management practice CT and ZT. Across locations, the genotypes "Munal" and "HD-2967" were the best performers and high stable in CT and ZT, respectively. Genotypes "HD-2824" and "DPW-621-50", and "Munal" may serve as diverse parents for developing high quality, climate smart, locally adapted genotypes for BR in CT and ZT, respectively. Genotypes "HD-2932", "BAZ" and "JW-3288", and "GW-322" and "HD-2967" are suitable for developing locally adapted stress tolerant genotypes for MP in management practices CT and ZT, respectively. Relatively small GxM and GxExM interactions in PB preclude in making definitive conclusions.
