Effect of Irrigation Intervals and Kaolin Particle Film Applications on Growth, Yield and some Water Relations of Eggplant

Abstract

The present study was conducted during consecutive summer season of 2014 and 2015 at a private farm in Kafrelsheikh Governorate, Egypt. This study aimed mainly to investigate the effect of irrigation intervals i.e., 7, 11 and 15 days among irrigations and kaolin foliar application with different concentrations, 0, 2 and 4% on Eggplant cv. Sawad EL Laiel. The shortest irrigation interval 7 days increased the all plant growth parameters under study namely, stem length, branche number, leaf number, leaf area, plant fresh weight and yield components as well as increased the parameters of fruit quality and productivity of irrigation. The kaolin foliar application concentrations improved plant growth, yield and fruit parameters. The highest early and total yields with favorable quality were attained under the shortest period (7 days) with kaolin foliar application at (2%), while the kaolin concentration at 4% under water stress condition (irrigation at 11 or 15 days period) was the best for plant growth, yield, and productivity irrigation with water saving the seasonal applied water than without kaolin or 2% treatments.

Evaluation of Growth, Yield and Active Ingredients in Fenugreek Plants under Different Potassium Fertilizer Rates and Kaolin Application

“…However, the highest concentration of kaolin gave a significant increase regard fenugreek growth parameter compared to control in the two tested seasons. In addition, Faralli [17] found that the kaolin foliar application concentrations improved eggplant growth (stem length, branch number and plant fresh weight) compared to control. Kaolin particle film increased relative water content of tomato leaves and irrigation water use efficiency which reflected in increasing plant growth [18].…”
