“…In this study, the effects of plant density between non-flooded culture (direct-seeding technology) and flooded culture (1.2 : 1) were ignored, which results were also clarified by our previous studies (He et al, 2013). The study aims at (a) comparing the growth characteristics of all plant organs (including aboveground and underground parts) grown under DI, furrow irrigation with plastic mulching (FIM or called as GCRPSs system) and furrow irrigation with non-mulching (FIN or named 'aerobic rice' system) under non-flooded conditions and (b) determining the optimum irrigation scheme for high grain yield under DI.…”

“…Although yield and water use efficiency (WUE) were higher in the DI treatment than in the GCRPSs and 'aerobic rice' treatments when soil water potential in the 0-20 cm depth was maintained between 0 and −30 KPa, grain yield in the DI treatment was still significantly less than that in the traditional flood irrigation treatment (He et al, 2013(He et al, , 2014. Therefore, it is important to diminish the yield gap between DI and flood-irrigated rice in arid region.…”

“…Drip irrigation, especially when combined with plastic mulching, has potential to save water and increase profits more than furrow irrigation in many field crops (Cassel et al, 2001;Cetin & Bilgel, 2002;Singandhupe et al, 2003). Also, rice grown in drip irrigation is considered as a more superior non-flooded cultivation technology than that grown in furrow irrigation methods such as GCRPSs and 'aerobic rice' systems in arid region (He et al, 2013(He et al, , 2014. However, there is little information regarding growth characteristics and adaptation mechanisms of rice plants in non-flooded irrigation including drip irrigation with plastic mulching (DI), GCRPSs and 'aerobic rice' in arid region.…”

The objectives of this field experiment were to study the growth characteristics and yield potential of rice plants under non-flooded irrigation in arid area. Non-flooded treatments included drip irrigation with plastic mulching treatments (DIs), furrow irrigation with plastic mulching treatment (FIM) and furrow irrigation with non-mulching treatment (FIN). Conventional flooded cultivation (F) was check treatment (CK). The four drip irrigation treatments differed in the amount of water applied before and after panicle initiation. Root length density, leaf dry weight, shoot dry weight and root activity were generally higher in the non-flood-irrigated treatments (especially the drip-irrigated treatments) than in the flood-irrigated treatment at mid-tillering. However, the growth and development of rice plants were limited after jointing in the non-flooded irrigation treatments. Increasing the root/shoot ratio and root length density in the 20-40 cm depth and decreasing specific root length at 0-20 cm soil layer were important mechanisms for helping the rice plants to adapt to the non-flooded environmental stresses. Finally, the grain yield in the non-flooded irrigation treatments was lower than that in the F treatment. These low yields were mainly attributed to the low root length density at 0-20 cm depth and root activity. Generally speaking, the restricted degrees in the DIs were smaller than that in the FIM and FIN treatments. Among the DIs, both the highest grain yield (8223-8900 kg ha −1 ) and the highest water use efficiency (WUE) (0.63) were observed when the soil water content was kept at −30 kPa before panicle initiation and at −15 kPa after panicle initiation (referred to as the DI2 treatment). The yield in the DI2 treatment was not significantly different than that in the flood-irrigated treatment. However, WUE was 2.5 times higher in the DI2 treatment than in the F treatment. These results suggest that drip irrigation technology can be considered as a better water-saving cultivation of rice plants in arid region.

“…The drip irrigation treatment had more effective tillers, more roots in topsoil, higher WUE, and greater economic benefit in rice (He, Ma, Yang, Chen, & Jia, 2013), but less yield compare with conventional flooding irrigation. Drip irrigation maintained a competitive grain yield and water productivity, and greatly reduced pollution risk to the environment.…”

The field experiment was conducted to investigate the effect of drip irrigation treatments such as three lateral distances (0.6 m, 0.8 m or 1.0 m lateral distance) on growth parameters physiological characters, yield and water use of rice under two discharge rates drippers (0.6 or 1.0 litre per hour emitters). Among the lateral distances, 0.8 m lateral distance adjudged as optimum spacing for its better performance in growth, physiological and yield attributes than rest of the lateral distances. Between two-discharge rates, 1.0 lph drippers out performed 0.6 lph drippers in grain yield. Interactively, laterals spaced at 0.8 m with 1.0 lph drippers exhibited better performance by way of growth parameters (such as plant height, tiller density, root biomass, total dry matter accumulation), physiological attributes (such as  w , Chlorophyll content, Catalase activity and Malondialdehyde content), yield and its components (such as productive tillers, spikelet numbers, filled grain percentage, Harvest Index) along with water productivity. Drip irrigation confirms to increase in water productivity in the present study with water saving of 27.4% over the conventional aerobic rice cultivation. Enhanced physiological activities showed increased growth and yield in rice under 0.8 m lateral distance drip irrigation which is a viable tool for balanced source sink relation. Our results indicated that the lateral spacing of 0.8 m with 1.0 lph drippers is best for rice cultivation in enhancing the growth, physiology, grain yield and water productivity.

“…Correlation analysis showed that the roots at the a1 and b1 sites were positively significantly correlated with yield components and aboveground agronomic traits. Therefore, improving root development at the a1 and b1 sites at flowering stage could be a key factor to obtain higher grain yield and good agronomic performance under plastic mulching drip irrigation (He et al, 2013). The experiment demonstrates that the di treatment has greater water saving capacity and lower yield and economic benefit gaps than the fim and fin treatments compared with the cf treatment, and would therefore be a better water-saving technology in areas of water scarcity (He et al, 2015).…”

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.
