“…Excess soil moisture is a commonly identified constraint in establishing a dry season, non-rice crop after puddled monsoon rice on the fine-textured clayey soils found on much of Asia’s rice lands. Cropping systems in these environments in South Asia often include two or more crops where monsoon (or ‘ kharif’ ) season flooded rice is followed by winter (or ‘ rabi’ ) season flooded rice or dryland crops such as maize, wheat, pulses or oilseeds, and in some cases also a third short-duration crop in spring ( Islam et al, 2019 ; Timsina and Connor, 2001 ; Timsina et al, 2010 ). In rice based cropping systems, the most common practice for crop establishment in following dry season crops is tillage followed by manual broadcasting of seed.…”

Highlights Strip-tillage of Asian wet clay soil to intensify cropping resulted in poor seedbed. Conventional blades and setting (four per row) created optimum clods, but low backfill. Contrary, an improved blade (> 50 mm depth) created optimum clods and high backfill. Backfill increased further for 6 straight blades/row, but furrow volume increased. Straight blade (four per row, ≥ 75 mm depth setting) is recommended for Asian wet clay soil.

“…Potatoes can be used in the production of ethanol, paper industry and provide raw material to the chemical industry (FAO, 2017). become the main limitation for crop production (Murad et al, 2018 andIslam et al, 2019). Potato is one of the sensitive crops to soil moisture stress, which requires a systematic water supply schedule (Ayas, 2013).…”

el-Khaimah, Qalyubiah Governorate. The aim of the current investigation was to study the impact of three planting dates (18-Dec, 7-Jan and 27-Jan), three irrigation levels at 60, 80 and 100% of irrigation water requirements (IR) and their interaction on potato crop productivity. 9 treatments were obtained by combination of different planting dates and irrigation levels.Planting dates were arranged as the main plots, while, irrigation levels were arranged in the sub plots, The obtained results indicated that the highest tuber yield was obtained by the first planting date (18 Dec.) during both studied seasons, While, The highest plant growth parameters and tuber yield per plant were obtained by 100% followed by 80% irrigation level during both seasons. However, the interaction effectindicated that first planting date (18-Dec) combined with 100 % irrigation level gave the highest potato tuber productivity than the other treatments, whereas the interaction of first planting date 18-(Dec) combined with 80% irrigation level gave the best for water use efficiency compared to the other treatments during both tested seasons.

“…Conservation agriculture-based sustainable Intensification (CASI) has been proposed as package of practices that could be used to improve the sustainability of smallholder farm productivity and profitability (Gathala et al, 2013;Gathala et al, 2021;Islam et al, 2019;Jat et al, 2021;Keil et al, 2015). However, existing extension systems are not set up to support widespread adoption by using the innovation structures to have the impact necessary to solve food security and livelihood demands.…”

“…The Eastern Gangetic Plains (EGP) of Bangladesh, India and Nepal, is home to over 300 million people, with the world's highest concentration of rural poverty and a strong dependence on agriculture for food security and livelihoods (Ericksen et al, 2011). The EGP has the potential to become a major contributor to South Asian regional food security, but rice and wheat productivity remain low and diversification is limited because of poorly developed markets, sparse agricultural knowledge and service networks, and inadequate development of available water resources and sustainable production practices (Gathala et al, 2021;Islam et al, 2019;Sugden et al, 2014). Most smallholder farmers have small areas of land (<1 ha) and labour shortages are becoming more acute as feminization of agriculture increases (Darbas et al, 2020), but this has not occurred equally across the region (Sen et al, 2019).…”

“…SRFSI focused on raising the productivity of the rice-, wheat-and maize-based farming systems characteristic of the EGP with Conservation Agriculture (CA) practices. Farm mechanization has been a strong focus, specifically the introduction of CA machinery which reduces inputs (labour, water, seed) while improving soil fertility by retaining and planting into crop residues (Gathala et al, 2020a;Gathala et al, 2020b;Islam et al, 2019;Sinha et al, 2019). This strategy is referred to as Sustainable Intensification (SI).…”

Conservation agriculture-based sustainable intensification (CASI) is a package of practices that could improve the sustainability of smallholder farm productivity and profitability. However, existing extension systems are unable to facilitate widespread adoption to have the impact necessary to meet food security and livelihood requirements. This paper examines the utility of 'Innovation Platforms' (IPs) as a tool to catalyse adoption of CASI for smallholder farmers in South Asia and generate opportunities for rural micro-entrepreneurship in areas with high rates of poverty, small farm sizes and complex labour markets. We established 37 village-level and five District-level IPs across the Eastern Gangetic Plains of Nepal, Bangladesh, and India. IPs allowed widespread uptake of CASI with benefits to smallholder farmers, input and output suppliers, and enabled extension systems to be more efficient. There was variability across locations with different modes of IPs established, building on existing farmer or community youth groups, and enabling micro-entrepreneur business opportunities. IPs were effective in developing trust in communities, among stakeholders, empowering rural youth and women through direct engagement. Ensuring strong ownership was key. Further work is needed to provide opportunities for high-level policy support to assist IPs to have a wider impact in supporting large-scale adoption of CASI.
