Plant breediers must respond to the threats posed by climate change in order to help ensure global food security in the short and long term. A better understanding of the genetic underpinnings of heat tolerance can contribute to efforts to develop more resilient crops. The exome capture data from 149 spring wheat lines provided in this dataset were used to search for loci, including loci from an exotic wheat relative, that could contribute to enhanced heat tolerance. The HIBAP_Germplasm file provides a HIBAP_NUMBER that appears in name of the exome capture files to link them to specific germplasm.The methods and results of the study are described in the accompanying article.

The Green Revolution has led to intensive, irrigated rice-wheat systems across the Indo-Gangetic Plains (IGP). The limited turn-around time between rice harvest and sowing of the next crop (wheat) and mechanized harvesting of rice pose a critical challenge for farmers to sustainably handle the surplus rice residues. Because only a few economically viable residue-management alternatives are readily available, a majority of the 2.5 million farmers burn an estimated 23 million metric tons of rice stubble in October and November. The rice residue burning and the resultant increase in air pollution have received significant media attention in the recent past. Residue burning causes the emission of short-lived climate pollutants, such as methane and black carbon. A solution for residue burning is offered by the application of two fundamental principles of Conservation Agriculture (CA) in wheat – minimal soil disturbance and crop residue retention for mulching. CA is heralded as more sustainable than traditional tillage alternatives. The technology diffusion has so far been only marginal in eastern IGP due to multiple institutional and economic constraints. The present survey was conducted in four districts of Punjab to (a) identify the adoption pattern of CA and alternative tillage practices among farmers (b) elicit farmer perceptions regarding different tillage options in different dimensions such as cost of cultivation, yield, input requirement, pest infestation, etc. Most of the sample farmers were visited by CIMMYT researchers in 2018 and 2021.

Sustainable intensification of agriculture (SIA) is promoted by a number of Research-for-Development (R4D) programs and institutions to improve yields, rural incomes, and food security while decreasing or at least maintaining the current expansion of agricultural land and other adverse environmental impacts. One of the major SIA programs was the Cereal System Initiative for South Asia (CSISA), which was established in 2009 with the goal of benefiting more than 8 million farmers by the end of 2020 (https://csisa.org/). After the initial phase, the project shifted its regional focus, toward the eastern Indo-Gangetic Plains. The region is characterized by small farm sizes, low incomes, and comparatively low levels of agricultural mechanization, irrigation, and productivity. The project partners with the national universities, State Departments of Agriculture, national-level initiatives, livelihoods programs, state agricultural universities, NGOs, and private sector entities such as agricultural machinery manufacturers, dealers, and local service providers. The current census among rural households was conducted in 2020, as part of CSISA Nepal. The main research question while starting this farmer census was to estimate the farm-level reach and adoption of CSISA-interventions in Nepal. We aimed to show how inclusive these technologies are, and whether there is a need for social targeting. The study was conducted in 9 districts of Nepal Terai region - Banke, Bardiya, Dang, Kailali, Kanchanpur, Kapilvastu, Nawalpur, Parasi, and Rupendehi. These are the districts where CSISA project has been active in the last decade, and they are major cereal producers in the country. Fifty villages were selected in total – 40 were selected randomly, and 10 from the list of villages where CSISA has been active. In all the 50 villages, village census was conducted in which farmer information (name, phone number, etc.) alongside technology adoption details were collected. During the two-month period (2020), about 38,000 rural households were covered as part of the census.

The data comes from a survey designed to understand the scope of LLL services in four districts of Mid- and Far-western developmental regions of Nepal Terai that are part of the IGB and have the potential to scale-up LLL. Samples were collected from the districts Banke, Bardiya, Kailali and Kanchanpur. The International Maize and Wheat Improvement Center, Nepal, led the data collection in 2015. From each district, sub-districts (Village Developmental Committees, or VDCs) were purposively selected from Cereal Systems Initiatives for South Asia (CSISA) project (https://csisa.org/) working areas. The project was operational in 10 VDCs. The sampling strategy consisted of 50 percent of samples randomly selected from the list within CSISA project area and 50 percent of samples randomly selected beyond the CSISA project areas from the same VDCs. From each VDC, 40 sample households were selected randomly, resulting in an overall sample of 400 households (40 households from 10 sub-districts of four districts). An additional six samples were collected from one of the districts due to a higher proportion of rice-wheat systems in that district, bringing the overall sample size to 406.

Genomic prediction methods may be used to enhance efforts to rapidly introgress traits of interest from exotic germplasm into elite materials. This study examined the performance of different genomic prediction models using genotypic and phenotypic data related to 8416 Mexican landrace accessions and 2403 Iranian landrace accessions stored in germplasm banks. The Mexican and Iranian collections were evaluated under optimal, drought, and heat conditions for several traits including the highly heritable traits, days to heading (DTH), and days to maturity (DTM). The results of the different analyses are reported in the accompanying journal article.

The Indo-Gangetic Plains (IGP) in north-west (NW) India are facing a severe decline in ground water due to prevalent rice-based cropping systems. To combat this issue, conservation agriculture (CA) with an alternative crop/s, such as maize, is being promoted. Recently, surface drip fertigation has also been evaluated as a viable option to address low-nutrient use efficiency and water scarcity problems for cereals. While the individual benefits of CA and sub-surface drip (SSD) irrigation on water economy are well-established, information regarding their combined effect in cereal-based systems is lacking. Therefore, we conducted a two-year field experiment in maize, under an ongoing CA-based maize-wheat system, to evaluate the complementarity of CA with SSD irrigation through two technological interventions–– CA+ (residue retained CA + SSD), PCA+ (partial CA without residue + SSD) – at different N rates (0, 120 and 150 kg N ha-1) in comparison to traditional furrow irrigated (FI) CA and conventional tillage (CT) at 120 kg N ha-1. Our results showed that CA+ had the highest grain yield (8.2 t ha-1), followed by PCA+ (8.1 t ha-1). The grain yield under CA+ at 150 kg N ha-1 was 27% and 30% higher than CA and CT, respectively. Even at the same N level (120 kg N ha-1), CA+ outperformed CA and CT by 16% and 18%, respectively. The physiological performance of maize also revealed that CA+ based plots with 120 kg N ha-1 had 12% and 3% higher photosynthesis rate at knee-high and silking, respectively compared to FI-CA and CT. Overall, compared to the FI-CA and CT, SSD-based CA+ and PCA+ saved 54% irrigation water and increased water productivity (WP) by more than twice. Similarly, a greater number of split N application through fertigation in PCA+ and CA+ increased agronomic nitrogen use efficiency (NUE) and recover efficiency by 8–19% and 14–25%, respectively. Net returns from PCA+ and CA+ at 150 kg N ha-1 were significantly higher by US$ 491 and 456, respectively than the FI-CA and CT treatments. Therefore, CA coupled with SSD provided tangible benefits in terms of yield, irrigation water saving, WP, NUE and profitability. Efforts should be directed towards increasing farmers’ awareness of the benefits of such promising technology for the cultivating food grains and commercial crops such as maize. Concurrently, government support and strict policies are required to enhance the system adaptability.

CONTEXT: Intensive cropping and elevated input use to achieve high crop yields have resulted in the injudicious use of resources and a consequent reduction in profit margins for farmers in the Eastern Gangetic Plains (EGP) region of South Asia. In this region rice-wheat (RW) under conventional tillage (CT) management is the most widely cultivated cropping system. While conservation agriculture (CA)-based management practices have been demonstrated to improve cropping system performance, they are considered by many farmers to be risky, and adoption of CA in rice-based cropping systems is low. There has been little agronomic research into alternative cropping systems to develop diversification options appropriate for the EGP. OBJECTIVE: We hypothesized that shifting from a conventional RW system to crop establishment practices which incorporate CA principles, combined with alternative crops could improve the whole cropping system in terms of productivity, profitability, and nutritional security (as crop protein).
