“…Application of three supplementary irrigations doubled the seed yields of pigeon pea in alfisols (Chauhan, 1990). These results were further confirmed that depending on water stress, supplementary irrigation was helpful in upscaling grain yield (Praharaj et al, 2017 andRamulu et al, 2020). The results obtained in the present experiment are also in conformity with the findings of Rao et al (1983) and Khanna et al (1980).…”

Background: The food grain and non-food grain crops occupy 48 and 68% area respectively under rain fed condition. Due to uneven rainfall, the rainfed crop suffers for want of adequate soil moisture at critical growth stages. Under such situation, protective irrigation ensures adequate soil moisture which results higher production. Crops like tomato, maize, groundnut and red gram are predominantly grown during kharif as rain fed crops. Relieving the soil moisture stress during the critical crop growth stages with more efficient irrigation system assumes importance in rain fed farming. Methods: An experiment was conducted for three years during kharif 2008, 2009 and 2010 at the College Farm, Prof. Jayashankar Telangana State Agril. University, Rajendranagar, Hyderabad on a sandy loam soil to study the yield advantage of protective sprinkler irrigation to kharif grown rain fed tomato, maize, groundnut and red gram crops. The trial was conducted in strip plot design with protective sprinkler irrigations as main plots and rainfed kharif crops as sub-plots and replicated thrice. The three main treatments comprised of - one protective sprinkler irrigation at flower/peg/tassel initiation, two protective sprinkler irrigations at flower and fruiting, tassel and grain filling, peg formation and pod filling and flowering and pod filling stages and rain fed (control). The sub treatments consisted of four crops- tomato, maize, groundnut and red gram. Result: There was an increase in yield with one and two protective sprinkler irrigations by 16.7 and 27.9; 17.7 and 44 5; 26.4 and 34.5 and 21.1 and 28.9% over their corresponding rain fed crops of tomato, groundnut, maize and red gram, respectively. There was an increase of 20.4 and 31.6% in Maize Equivalent Yield (MEY) with one and two protective irrigations as compared to rain fed crop. The water productivity was lower in all the crops grown under rain fed conditions (0.77 kg MEY m-3) as compared to that of one and two protective irrigations.

“…In this era of life-saving/ supplementary irrigation (mostly adopted in water deficit areas under rainfed/dryland agro-ecosystems), there is a larger need to apply both fertilizers and water through trickle drip especially at critical stages to improve productivity of crop, water and nutrient 8 (Table 1). A single irrigation (20 mm in 5 splits) through drip-fertigation with half of N and K fertilizers at branching of a long duration pigeonpea, produced significantly higher (20%) grain yields and economic return over rainfed crop 1,2,4 . Similarly, an experiment carried out at ICAR-Indian Institute of Pulses Research, Kanpur during 2010-2014 also revealed the compatibility of drip-fertigation with that of intercropping in a wide spaced pulse crop -a long duration pigeonpea.…”

Water is a critical input for productivity enhancement especially of field crops. Its judicious and optimum use is needed utmost for realizing higher resource use efficiency and plugging gaps in production. Resource conservation technologies or key technological interventions, which could alter or rectify the usage pattern or strategies in freshwater utilization in agriculture, are the need of the hour. Tactical or strategic approach in water management could help in conserving and making more-efficient use of scarce water resources through integrated management combined with selected external inputs/technologies. In this context, the scientific interventions on water management involving precision levelling of land, no tillage or reduced tillage systems, furrow irrigated raised bed planting or broad bed furrow systems, management of soil cover and crop diversification and other inclusive technological practices could enforce appropriate water management schedules.

Rice is the most important staple food crop of our country. Due to climatic condition and geographical situation our country is the most important rice growing country of the whole world. It is mostly grown during kharif season, but interestingly around 11.7 M ha of land remains fallow after kharif rice were harvested due to several limitations. Efficient utilization of these fallow land may increase the productivity and make the whole system sustainable. Soil condition and climatic situation clearly suggest that short duration crop can easily be fit in that situation. Pulse takes an important position in human’s daily life. It not only providing high quality protein but also benefit the cropping system in several ways. The resources present in the rice fallows clearly giving an opportunity to introduce different pulse crop there. It will surely be an excellent inclusion. If the location specific constraints are been managed efficiently then those unutilized lands can be efficiently converted into productive one. It will not only increase the production of the system but also strengthen the economic condition of the farmers, improve the soil condition and more over it will ensure nutritional security of the people of our country.
