The influences of irrigation at three intervals (every 4, 6 and 8 days), potassium at three rates (24, 48 and 72 kg K 2 O/fad) and phosphorus at three rates (15, 30 and 45 kg P 2 O 5 /fad) on yield, yield components and seed quality of peanut cultivar Giza 5 were studied in a private farm at El-Salhya region, Sharkia Governorate during summer seasons of 2006 and 2007. Results show that either irrigation or fertilization treatments affected significantly all studied characters. Decreasing irrigation intervals from 8 to 6 and then to 4 days, increasing K fertilizer levels from 24 to 48 and then to 72 kg K 2 O/ fad and increasing P fertilizer levels from 15 to 30 and then to 45 kg P 2 O 5 /fad increased significantly plant height, number of branches/plant, number of pods/plant, seed yield/plant, 100-pod weight, shelling percentage, pod, seed and foliage yields/fad. However, oil and protein percentages significantly increased by any increase of K or P fertilizer, but with respect to irrigation treatments, the highest oil percentage was attained when the irrigation intervals were at 4 or 8 days with no significant effect on protein percentage. The interaction effect between irrigation intervals and K fertilizer levels on 100-pod weight and seed yield/fad as well as the interaction effect between irrigation intervals and P fertilizer levels on 100-pod weight and foliage yield/fad were significant. Irrigation every 4 days under 72 kg K 2 O/fad or 45 kg P 2 O 5 /fad gave the heaviest 100-pod weight and highest seed yield/fad. Foliage yield/fad were the highest with 4 days irrigation interval when 30 or 45 kg P 2 O 5 /fad were applied. Significant and positive correlation coefficients were detected between seed yield/fad and all studied characters, while 206 ABD EL-MAKSOUD et al.

“…These results might be due to the higher irrigation frequency, such as F2 and F3, with the quantity of applied water at each irrigation being just sufficient to wet the root zone without causing water leaching, thereby preventing leaching losses of nitrogen as well. This increase in available soil water in the root zone, on the other hand, might have increased the mineralization of organic matter leading to increased availability of nitrogen and hence a better utilization of the applied nitrogen and subsequently help various physiological processes in plant growth and finally increase yield and yield components (Ramireddy et al 1982). In contrast, at the low irrigation frequencies, the quantity of applied water at each irrigation was higher than the soilwater storage capacity, thereby increasing leaching losses of nitrogen.…”

Irrigation frequency is one of the most important factors in drip irrigation scheduling that affects the soil water regime, the water and fertilization use efficiency and the crop yield, although the same quantity of water is applied. Therefore, field experiments were conducted for 2 years in the summer season of 2005 and 2006 on sandy soils to investigate the effects of irrigation frequency and their interaction with nitrogen fertilization on water distribution, grain yield, yield components and water use efficiency (WUE) of two white grain maize hybrids (Zea mays L.). The experiment was conducted by using a randomized complete block split‐split plot design, with four irrigation frequencies (once every 2, 3, 4 and 5 days), two nitrogen levels (190 and 380 kg N ha−1), and two maize hybrids (three‐way cross 310 and single cross 10) as the main‐plot, split‐plot, and split‐split plot treatments respectively. The results indicate that drip irrigation frequency did affect soil water content and retained soil water, depending on soil depth. Grain yield with the application of 190 kg N ha−1 was not statistically different from that at 380 kg N ha−1 at the irrigation frequency once every 5 days. However, the application of 190 kg N ha−1 resulted in a significant yield reduction of 25 %, 18 % and 9 % in 2005 and 20 %, 13 % and 6 % in 2006 compared with 380 kg N ha−1 at the irrigation frequencies once every 2, 3 and 4 days respectively. The response function between yield components and irrigation frequency treatments was quadratic in both growing seasons except for 100‐grain weight, where the function was linear. WUE increased with increasing irrigation frequency and nitrogen levels, and reached the maximum values at once every 2 and 3 days and at 380 kg N ha−1. In order to improve the WUE and grain yield for drip‐irrigated maize in sandy soils, it is recommended that irrigation frequency should be once every 2 or 3 days at the investigated nitrogen levels of 380 kg N ha−1 regardless of maize varieties. However, further optimization with a reduced nitrogen application rate should be aimed at and will have to be investigated.

“…Irrigation interval affects crop photosynthesis and dry matter production by affecting soil moisture. Reddy et al [43] showed that excessively long or short irrigation intervals are not conducive to crop growth and yield improvement. This can be attributed to the fact that soil water stress decreases the P n and G S , which finally results in the decrease in crop biomass and yield [19,44].…”

Improvement in Photosynthetic Rate and Grain Yield in Super-High-Yield Maize (Zea mays L.) by Optimizing Irrigation Interval under Mulch Drip Irrigation

High yield is one of the important goals of crop production, and close planting and optimum irrigation systems are important agronomic practices for increasing maize (Zea mays L.) grain yield. However, little is known about the effect of optimal irrigation interval on the photosynthetic rate (Pn) and dry matter accumulation (DM) of closely planted super-high-yield maize under drip irrigation under mulch. Therefore, the objective of this study was to determine the effects of irrigation interval on the leaf Pn, DM, and grain yield of closely planted super-high-yield maize under mulch drip irrigation in the Xinjiang Uygur Autonomous Region, Northwestern China. A field experiment was conducted using three irrigation intervals in 2016—namely, six days (D6), nine days (D9), and 12 days (D12)—and five irrigation intervals in 2017—namely, three days (D3), six days (D6), nine days (D9), 12 days (D12), and 15 days (D15). The Xianyu 335 high-yield maize hybrid was used in the test; the planting density was set to 12×104 plants ha−1, and an optimal irrigation quota of 540 mm was used. The results showed that during the irrigation period, (1) the soil moisture content (SMC), DM, leaf Pn, and grain yield of treatment D6 were higher than for other irrigation intervals, (2) the leaf Pn and stomatal conductance (GS) of the leaves of treatments D3, D9, D12, and D15 were significantly correlated with the SMC of the 0–40 cm soil layer, and (3) the leaf Pn of treatment D6 was significantly positively correlated with SMC in the 0–60 cm soil layer but not significantly correlated with GS. Irrigation treatment D6 was found to maintain high SMC, provide a water environment favorable to the growth of maize, and increase the leaf Pn and DM, and thereby obtain maize grain yield (20.6–21.0 t ha−1). Therefore, an optimal irrigation interval could be beneficial for adjusting soil moisture, leaf Pn, and DM in order to increase maize grain yield with drip irrigation under mulch.
