“…The differences between cultivars are mainly due to the interaction between their genetic makeup during growth stages and to the environmental factors prevailing during their development. Significant variations between wheat cultivars in biological yield as affected by number of irrigations and amount of applied water were reported by Moayedi et al (2010), Ahmad and Kumar (2015), Teama et al (2016) and Seleiman and Abdel-Aal (2018).…”

“…Tillering, elongation, booting, and grain formation were identified as moisture sensitive stages in wheat (Ali et al, 2007). Under scarcity of water, four irrigations scheduled at crown root initiation, tillering, flowering and milky stages saved two irrigations without significant yield loses (Ahmad and Kumar, 2015).The highest values of growth characters were obtained with five irrigations at crown root initiation, tillering, jointing, flowering and milking stages (Banker et al, 2008).Water stress through withholding irrigation at the ear emergence and grain filling phases reduced grain yield and its components as will as relative water content (Zarein et al, 2014). Decreasing number of irrigations decreased days to heading, days to maturity, plant height, number of spikes m -2 , number of grains spike -1 and 1000-kernel weight, grain yield, biological yield, and straw yield (El-Hag, 2017 andSeleiman andAbdel-Aal, 2018).…”

Field experiments were conducted at Shandaweel Agric. Res. Station, Sohag, Egypt, during the two growing seasons 2018/2019 and 2019/2020 to study the effect of six irrigation regimes, i.e. I1 (irrigation at tillering and elongation stage), I2 (irrigation at tillering and flowering stage), I3 (irrigation at tillering, elongation and flowering stage), I4 (irrigation at tillering, booting and grain filling stage), I5 (irrigation at tillering, elongation, booting and flowering stage) and I6 (irrigation at tillering, elongation, booting, flowering and grain filling stage) on some agronomic and physiological traits of four wheat cultivars, i.e.Shandaweel1, Sids 14, Sohag 4 and Sohag 5. Results showed that decreasing number of irrigations and amount of applied water at different growth stages significantly decreased all studied traits. The highest reduction was recorded under I1 (1432 m-3 ha-1) for all studied traits, except days to heading and number of spikes m-2. Meanwhile, the lowest reduction was observed under I5 (3088 m-3 ha-1) for all studied traits as compared to I6 (3965 m-3 ha-1 of applied water). Irrigation at both booting and flowering are essential to reduce loss in grain yield. Moreover, Sids 14 exhibited lower yield reduction under different irrigation regimes, while sohag 4 and Sohag 5 exhibited the highest yield reduction. Therefore, Sids 14 proved to be drought tolerant cultivar, while Sohag 4 and Sohag 5 were drought sensitive. Planting Sids 14 cultivar with irrigation at tillering, booting, grain filling stages (I4) are useful to save about (36.97%) of applied water without significant decrease in grain yield.

“…The total uptake of N was increased with increasing of N-fertilizer rates under different irrigation and bio-fertilizer treatments and the highest values (69.26 and 73.11 kg fed -1 ) were recorded for I 2 (11&12) the highest values of wheat and sunflower yields beside the total net income resulted from the application of nitrogen and biofertilizer, which ameliorated the water stress conditions for crop production. The net income for previous treatments were recorded the highest value (8036 LFed.…”

Two field trials were carried out at the experimental farm, Sakha Agricultural Research Station, Kafr El-Sheikh governorate during the two growing seasons 2014/ 2015 to investigate the effect of soil moisture depletion, nitrogen and biofertilizer application levels on yield water productivity of wheat and sunflower. The experiments were designed as split split plot with three replicates. The main plots were occupied by soil moisture depletion, while sub plots were devoted to nitrogen rates and sub sub plots were biofertilizer treatments. The main results can be summarized as follows: -Water applied and water consumptive use by wheat and sunflower were recorded highest values under irrigation I 1 .The highest values of water stored in the root zone, were recorded by irrigation I 1 while water application efficiency was achieved under I 2 either by wheat or sunflower crops. Water productivity and the amount of applied water were recorded highest values under irrigation I 2 and N 3 . The net income was recorded the highest value with I2 under N3 and b3. While the economical efficiency was recorded the highest value (2.81) by I2 with N3 for wheat. On the other hand, Net income for sunflower seed and economical efficiency were recorded the highest value 5368 LFed. -1 and (2.25) by under irrigation at 50% depletion of available soil moisture (I2) with 50kg Nfed. -1 and b3. It could be concluded that application of biotol + phosphorene +75 kgNFed. -1 for wheat. While addition of biotol+ phosphorene +50 kgNFed. -1 for sunflower under irrigation at 50% depletion of available soil moisture could be economically used for production of wheat and sunflower as well as under water shortage without adverse effect on wheat and sunflower productivity Copy Right, IJAR, 2016,.

“…It was noted that increment in number of filled grains spikes -1 was 24% in twice irrigated plots against the plot in which no irrigation was given. Ahmad and Kumar (2015) reported that with increasing the number of irrigations the percentage of filled grains per spike also increased. The genotype HI 1612 exhibited maximum number of filled grains spike -1 (40.67) and it was significantly higher as compared to the other genotypes.…”

Background: Water scarcity is one of the major problems faced by farmers for crop production. Productivity and sustainability of a crop like wheat which is highly susceptible to water stress could be affected the most. Identifying and growing such varieties of wheat which could thrive under restricted irrigation could solve the problem. The current study aimed to evaluate the performance of certain new wheat genotypes under restricted irrigation.Methods: A field experiment was conducted in eastern sub-Himalayan plains during Rabi season, 2016-2017 to evaluate the performance of certain wheat genotypes under restricted irrigation. The experiment was laid out in a split plot design with three different levels of irrigation, viz., no irrigation, one irrigation at CRI stage, two irrigations at CRI and booting stage, randomly allotted in main plots; while six genotypes comprising HI 1612, HD 2888, C 306, K 8027, HD 3171 and K 1317 were randomly allocated in sub plots.Result: It was observed that with increase in number of irrigation, the overall biomass production increased irrespective of genotypes. The highest biomass (7.38 t ha-1) was achieved in plots where two irrigations were given. Higher leaf area with increased plant height and tiller number as well as higher values of major yield components viz., number of spikes m-2 and number of filled grain spike-1 were also achieved in plots receiving two irrigations. The twice irrigated plot also exhibited higher yields (3.02 t ha-1) as compared to once irrigated plot. With increase in number of irrigation the grain yield increased significantly. Among the genotypes, HI 1612 reflected the maximum grain yield (2.76 t ha-1) under restricted irrigation though there was no significant variation in grain yield achieved with the other 5 genotypes except HD 3171.
