“…Besides this, raised bed planting yielded higher than flat planting by around 18.8% and conserved more water with enhanced WUE in chickpea (Ali, 2009). Two years' study at the ICAR-IIPR, Kanpur, Uttar Pradesh on Optimum Irrigation Scheduling (OIS) with irrigation applied at branch and pod development (BPD) showed significantly higher grain/biomass yield, harvest index (HI), net returns (NR), benefit : cost ratio (BCR) and productivity/day over others (Praharaj et al, 2017(Praharaj et al, , 2018. As a result, there was an increase in net water saving/WUE (~30%) and WP (~20%) following OIS at BPD over that in flood irrigation at both the stages to realize the same yield levels (2.65 t/ha).…”

Although greater efforts have been made to realize higher yields with desired quality from a number of high-yielding varieties of pulses with matching agro-technologies and proven tolerance to biotic/abiotic stresses, yet there has been a shortfall (though minimized to a greater extent now) in expected goals in production/productivity in these field crops. Therefore, there is a need for renewed and innovative approach for sustainable cropping intensification with pulses. In this context, water–a critical input for sustained crop production – is becoming limiting both under rainfed and irrigated conditions depending on its availability, competing factors, allocation to priority crops, and season of the year. It deserves all of us to use this precious commodity more judiciously, sensibly and need-based in agriculture through modern technology, especially in presence of diverse constraints. One of the approach for effective on-farm management of water is its precision use. One or two life-saving/supplementary irrigation through water-saving technologies (drip or sprinkler irrigation) during the post-rainy/ fall months or even under dryland condition could sustain productivity of crop. Some of the innovative agro-technologies could reinforce this by way of technology up-scaling and/or providing a sound footing for better water delivery/use. These include precision land levelling, no-till systems, furrow-irrigated raised bed planting, and crop diversification and its residue management. Thus, adaptive strategies for grain legumes or pulses will be highly location specific and offers an alternative for a quantum jump in its production with sustainable resource management and resource use efficiency (RUE). To conclude, strategic water management in pulses could play a significant role in their sustainable intensification/diversification of already scarce resource base in time to come (in the context of Sustainable Development Goals).

“…Micro-irrigation systems provide extensive control over water applications. Drip irrigation is a common type of microirrigation in which water is constantly given drop by drop directly to the root zone using drippers, resulting in a low volume of water, at low pressure and hence minimal energy costs [13] . Potential benefits and disadvantages of micro irrigation systems include:  Improved plant development and productivity  Improved plant growth and productivity by making better use of available water.…”

Rapid population growth associated with climate change has a significant impact on both agricultural and human health, primarily due to water scarcity. According to UNICEF, nearly two-thirds population of the world is affected by severe water scarcity at least one month of every year. Water stress has an adverse impact on crop physiology predominantly in photosynthetic capacity. Thus, crop water optimization in farming systems requires advancement in the monitoring of water stress at different times of the season in order to prevent plant physiological damage and maximise crop water use. Precision agriculture enabled by technical enhancement is able to solve this problem. Precision technologies such as Geographical Information Systems (GIS), Remote Sensing (RS), UAV Imagery (UAV), Wireless Sensor Networks (WSN) and Machine Learning & Artificial Intelligence (ML & AI) can be used to efficiently detect crop water stress. This article addresses current advancements in crop water stress monitoring and how they could be enhanced further in the near future.

“…Rabi pulse crops in the region are primarily grown under mono cropped conditions on residual soil moisture and are least preferred for application of other production inputs including irrigation. Promotion of micro-irrigation systems like drip and sprinkler system for pulse cultivation may be instrumental in saving irrigation water in this water scarce region (Praharaj et al 2018). The provisions for subsidies on these systems need to be continued with extensive awareness campaigns on their benefits (Sandhu et al 2016).…”

Bundelkhand region of India is primarily agrarian, vulnerable to natural calamities with low levels of industrialization and urbanization. Poor crop productivity, declining and irregular rainfall pattern and poor income levels make livelihood uncertain in the region. Pulse crops assume a special significance to the farm economy in Bundelkhand region as well as daily diets of local habitants. Chickpea, lentil, field pea, urdbean, mungbean and pigeon pea are the major pulse crops cultivated in the region. Data from Department of economics and statistics, Department of Agriculture and Cooperation and Farmers Welfare, New Delhi and the studies on pulses development of Bundelkhand region of India were analyzed. Pulses account for 32% of total agriculture produce and occupy about 33.6% of gross cropped area in the region. However, decline in area coverage of pulses has been observed in the region, in contrast to overall increase in gross cropped area in the region. The paper discusses about the various challenges confronting pulses cultivation in the region along with the possible intervention points for bringing out an enhanced pulse production.
