“…Results from out study shows yields of DSR were higher under SDI by 0.4 Mg ha −1 (2-yr mean) compared to flood irrigation. Rice with CA recorded similar or higher yields under SDI systems with laterals spaced at 60 cm in other studies 15,17,22 . Compared with CA based DSR, maize recorded higher REY in both years (ScIV and ScVI).…”

“…For precise water management, drip irrigation has shown several benefits in terms of irrigation water savings, increases in yield and quality, and increase in nutrient use efficiency in horticulture and vegetable crops 11 . To address water scarcity, surface drip irrigation has also been found a viable option for the cereal crops like maize 12,13 , rice and wheat 14,15 . However, adoption of surface drip irrigation in cereal systems has always remained cumbersome process of anchoring laterals at the beginning and removing after every crop due to field operations during the year under both conventional and conservation agriculture management systems.…”

A study was conducted to design productive, profitable, irrigation water¸ nitrogen and energy use efficient intensive cereal systems (rice-wheat; RW and maize-wheat; MW) in North-West India. Bundling of conservation agriculture (CA) with sub-surface drip irrigation termed as CA+ were compared with CA alone and conventional tillage based and flood irrigated RW rotation (farmer’s practice; ScI). In contrast to conventional till RW rotation which consumed 1889 mm ha−1 irrigation water (2-yr mean), CA+ system saved 58.4 and 95.5% irrigation water in RW and MW rotations, respectively. CA+ practices saved 45.8 and 22.7% of irrigation water in rice and maize, respectively compared to CA with flood irrigation. On a system basis, CA+ practices saved 46.7 and 44.7% irrigation water under RW (ScV) and MW (ScVI) systems compared to their respective CA-based systems with flood irrigation (ScIII and ScIV). CA+ in RW system recorded 11.2% higher crop productivity and improved irrigation water productivity by 145% and profitability by 29.2% compared to farmers’ practice. Substitution of rice with maize (MW system; ScVI) recorded 19.7% higher productivity, saved 84.5% of irrigation water and increased net returns by 48.9% compared to farmer’s practice. CA+ RW and MW system improved energy productivity by 75 and 169% and partial factor productivity of N by 44.6 and 49.6%, respectively compared to ScI. The sub-surface drip irrigation system saved the fertilizer N by 20% under CA systems. CA+ in RW and MW systems recorded ~13 and 5% (2-yr mean) higher profitability with 80% subsidy on installing sub-surface drip irrigation system and similar profitability without subsidy scenario compared with their respective flood irrigated CA-based systems.

“…Also, the drip fertigation at 5-10 cm soil depth favourably altered the root density. A similar increase in density was verified by Sharda et al (2017) in drip irrigated dry seeded rice with nitrogen fertigation. The dry weight of roots was 36.8% superior in JKRH 3333 hybrid under drip irrigation.…”

Background: Roots are the key elements in water saving rice cultivation. So, the response of rice roots are to be phenotyped under varied drip irrigation treatments. Methods: This study describes an investigation on rice root phenotyping under drip irrigation treatments in split-split plot design. Two lateral spacing levels (0.8 and 1.2m), laid at two depths of sub surface irrigation (5-10 and 15-20 cm) by solar powered and well operated irrigation were tested using TNRH 180, JKRH 3333 and ADT(R)45 rice genotypes during the summer season (2013 & 2014) in Coimbatore, India. Conventional aerobic irrigation was considered as control. Results and Discussion: An increased root length, root density (length and weight), root Adinosine Tri Phosphotase enzyme activity, root volume and filled grain percentage were favored in aerobic rice under the conditions of 0.8m lateral distance with 5-10cm depth of sub surface drip irrigation (SDI). Improved root characteristics were observed in JKRH 3333 rice hybrid, and root density and thickness favored the filled grains and yield increment in rice by drip irrigation. The 0.8m lateral distance laid out at 5-10cm depth SDI with solar system proliferated more roots at subsurface soil layer with significant yield increment in rice.

“…It is proved that drip fertigation technology is beneficial in boosting grain yield coupled with the increased values for water productivity besides improving the fertilizer use efficiency (Arulmozhiselvan, 2009). Drip irrigation is the future of irrigated agriculture, which needs to be strengthened by optimizing the technology for different crops (Sharda et al, 2016).…”

Abstract. Water saving was and remains an acute problem in places with water scarcity and inaccessibility. In order to solve this problem, drip irrigation started to be used in many countries, and for the first time, in Kazakhstan, there were used cultures that consume water sufficiently in large quantities such as rice and soybean. Ways of irrigation have significant effect on elements of structure of a rice and soybean crop. Drip irrigation with a two-row tape way of crops forms essentially distinct structure of a rice crop in comparison with usual technology of cultivation of rice and soybean. Rice (Оryza sativa L.) and soybean (Glycine Max L. Merr.) crops were grown in 2013-2016 to determine effect of drip irrigation in the different variants water levels on growth and productivity under conditions of the south-east of Kazakhstan. In result of three years of researches on studying of rice and soybean drip irrigation efficiency were made the following conclusions: Drip irrigation (Di) with application of the mulching film promotes emergence of early and amicable shoots of rice and soybean, intensive growth and development of plants, productivity increase. Drip irrigation with use of the mulching film at 8-10 times reduces a contamination of crops of rice that allows to exclude application of manual use, mechanical and chemical processing of crops. Use of the mulching film under rice drip irrigation promotes creation of the favorable nitric mode of the soil with big accumulation of ammoniac and nitrate nitrogen and mobilization of motile phosphorus. The best way of rice crops under drip irrigation is 2-row tape crops with distance between tapes of 70 cm and a row-spacing in a tape of 30 cm. At the same time the drip tape keeps within row-spacings in a tape. Comparison of the productivity of soybean varieties showed that productivity in variants with mulch far exceeded variants without mulching.
