Effect of irrigation intervals and foliar spray of zinc and silicon treatments on maize growth and yield components of maize

Abstract

Field experiments were carried out for two consecutive seasons at the Experimental Shandaweel Agricultural Research Station, Sohag Governorate, Upper Egypt, during the growing seasons of 2013 and 2014, to study the Effect of Irrigation intervals and foliar spray of zinc and silicon treatments on Maize growth and yield components of maize. Results indicated that, scheduling at every 10 days produced the highest plant height, Flag Leaf area (cm²), Cob length (cm), Weight of 100-grains (g), Biological yield (T/fad.) and Grain yield (ard./fed.) followed by irrigation at 15 and 20 days interval, in contrast irrigation at 25 days interval produced the lowest values and foliar spray of zinc and silicon treatments produced the highest plant height-improved yield and yield components of maize crop. The best yield was obtained from zinc + silicon treatments followed by zinc, silicon treatments. In contrast, untreated treatments produced the lowest values. It can be concluded that the scheduling at every 10 days and application of foliar spray of zinc + silicon treatments as the effective one could be recommended for scheduling irrigation at every 10 days with application of foliar spray of zinc + silicon treatments of maize crop at Shandaweel Agricultural Research Station, Sohag Governorate, Upper Egypt to obtained the best results from maize grain yield.

The impact of maize irrigation intervals and potassium fertiliser rates on mealybug populations, vegetative growth, and resulting yield

“…Furthermore, the vegetative growth measurements (plant height, diameter, and number of green leaves per plant), yield, and its component attributes (average ear length, ear weight, number of grains per ear, weight of 1000 grains, and grain yield) in maize plants irrigated every 10 days and when fertilised with a 114 kg K 2 O•ha -1 potassium fertiliser were significantly higher than in plants irrigated every 7 days without fertiliser, as shown in Tables S2 and S3. These findings are in line with Abdelgalil et al (2022). They mentioned that irrigation at every 10 days produced the highest plant height, cob length, weight of 100 grains and grain yield as compared to the irrigation every 15 and 20 days.…”

Enhancing Crop Resilience to Drought Stress: Antitranspirants, Zeolite and Water Conservation Strategies for Strategic Crop Productivity

“…Moreover, the drought stress conditions resulted in diminished vegetative and reproductive growth, as evidenced by decreased plant height, dry and fresh weights, ears per plant, ear weight, and grain yield. Abdelgalil et al, (2022) conducted a study to explore the impact of varying irrigation intervals on the growth and yield of maize. The outcomes revealed that the most favorable outcomes in terms of plant height, cob length, biological yield, and grain yield were observed with irrigation occurring every 10 days.…”
