“…In a study carried in Bangladesh, [ 44 ] documented 51% higher yields of the earliest 3 improved varieties (Bari-Masur 1, 2 and 3) over landraces. Therefore, even though our estimates are on the lower side, in the face of several confounding factors and the predominantly old, improved varieties in the sample which are in the counterfactual group, we are convinced that our results are reasonable.…”

The advent of improved lentil varieties (ILVs) in the mid-1990s solved the disease problem which almost halted lentil production in Bangladesh. Levels of adoption of ILVs have been documented in the literature, but little is known about their impacts. Applying an instrumental variables regression to data collected from a sample of 1,694 lentil plots and DNA fingerprinting for varietal identification, this study provides estimates of the plot-level impacts of adoption of ILVs in Bangladesh. Model results show that adoption of ILVs is associated with 14.3% (181.14 kg/ha) higher yields and 17.23% (US$169.44/ha) higher gross margins. Since 45% of lentil area is under ILVs, they generated over 8.77 tones (6%) more supply of lentils from domestic sources, saving the country US$8.22 million in imports in 2015 alone. By investing in the generation and scaling of ILVs, Bangladesh and other South Asian countries with similar agro-ecologies can increase production and decrease dependency on lentil imports.

“…This study highlighted the fact that a profitable new technology can spread quickly among poor small holders and contribute to alleviation of their poverty providing it is coupled with an outreach program. Another household survey in Ethiopia and the gross national data of Nepal provide additional examples of how local and national economic impacts of new lentil technologies can be substantial (Aw Hassan et al 2009;Neupane et al 2008); and emphasize the need to connect research outputs with outreach campaigns. Unfortunately, putatively profitable technologies have not yet reached farmers in many other countries.…”

“…Among the poorer lentil producers Bangladesh and Nepal stand out positively. The Bangladesh case has been thoroughly investigated through a recent household survey (Aw Hassan et al 2009). Cooperation between ICARDA and the national program resulted in the release of a cultivar, BARI Masur 4, with a high yield potential and resistance to the major diseasesrust and Stemphylium blight.…”

Lentils play a major role in the food and nutritional security of millions, particularly among lowincome Asian families, because of the high protein content of their seed. As is the case for many pulses, lentils play an important role as a rotation crop, enhancing soil fertility and providing other environmental services in production systems. While its production has risen globally at 8.6 kg/ ha/year from 1961 to 2008, the major challenge is to increase investment in lentil improvement (both research and outreach) in countries where the crop is part of the production system. Where currently grown the major abiotic stresses are low moisture availability and high temperatures in spring, and winter cold at high elevations. Among biotic stresses, rust, and vascular wilt are key, and resistance has resulted in improvements in performance. Additional production constraints include the agronomic problems of pod loss, lodging and poor crop management. Adequate variability for most genetic constraints exists within the gene pool allowing breeding. However, several key traits, such as biomass yield, pod shed, nitrogen fixation and resistance to aphids are not currently addressable by breeding because of insufficient variation. Among lentil-producing developing countries, policies have not yet focused on lentil development needs to enhance food security and provide a remunerative rotation crop for cereals. Looking towards a future in which there is likely to be less water available to agriculture, climate change, food insecurity, rising costs for inorganic nitrogen fertilizer, and an increasingly nutrition-conscious society-collectively these give a bright future for a highly nutritious food produced by a nitrogenfixing crop such as lentil adapted to the farming systems of marginal lands.

“…1b). There has also been a decreasing yield trend in Pakistan, but yields are increasing in Bangladesh mainly due to adoption of varieties with increased resistance to the major disease, stemphylium blight (Aw-Hassan et al 2009). The area sown to lentil has declined in Turkey (Fig.…”

Although there is increasing awareness of the importance of food legumes in human, animal and soil health, adoption of improved production technologies for food legume crops is not proceeding at the same pace as for cereal crops. Over the previous decade, the only food legumes to have shown significant production increases have been chickpea, lentil and faba bean in North America, chickpea in Australia, and faba bean in Europe. In smallholder farming in developing countries, production trends have mostly been static or have declined over the past decade despite the existence of technology that should permit higher and more stable yields. Ability to reverse negative trends is jeopardized by climate change as food legumes are mostly grown rainfed and are being exposed to increasingly variable and extreme weather. This review examines recent innovations in cultivation technology for the major food legumes-chickpea, lentil, dry pea, faba bean, lupin, common bean, mung bean, black gram, cowpea, and pigeonpea-and explores constraints to their adoption, particularly by resource-poor smallholder farmers. Conservation agriculture, involving minimum soil disturbance, maximum soil cover, and diverse rotations, has contributed to sustainable cropping system production in large-scale commercial farming systems in the Americas, Europe, Australia, and Turkey. Temperate food legumes have been incorporated into such systems. Adoption of conservation agriculture is only just beginning for smallholder farming in Asia and Africa, catalyzed by the development of low-cost implements suitable for minimum tillage. Water use efficiency improves with conservation agriculture as it allows for earlier planting, reduced soil evaporation, better weed management, and increased access to nutrients. Ecosystem-based approaches to plant nutrition are evolving which place more reliance on accessing organic and mineral reservoirs than in replenishing the immediately available pool with chemical fertilizers, leading to enhanced nutrient use efficiency of cropping systems. Ecosystem-based approaches are also being applied to management of weeds, diseases, and insect pests of food legumes, again with decreased reliance on synthetic chemicals. In achieving sustainable agricultural production systems, there is increasing realization of the need to move towards the tenets of organic agriculture, as exemplified in conservation agriculture and ecosystem-based approaches to plant nutrition and pest management.
