Improving Faba Bean Productivity in Salt Affected Soil Through Calcium Nutrition.

Abstract

Two field experiments were conducted in Wadi El-Natroon Desert Experimental Station, Faculty of Agriculture, Cairo University, El- Beheira Governorate, Egypt, during two successive winter season (2017/18 and 2018/19) The study aimed to show the performance of two faba bean varieties (Sakha-1 and Nubaria3) as affected by three levels of calcium nutrition (0, 2 and 4 g Ca/liter) under three dates for applying calcium (45, 60 and 45 and 60 days from sowing date). The design used was A split-spilt plot design with three replications. The main plots consisted of the varieties; sub-plots were allocated to the dates of applying calcium, while sub-sub plots were devoted to the calcium concentration. The collecting results could be summarized as follows: the greatest performance of the two varieties was obtained from treatment by 4g Ca/L which recorded the highest number of branches, pods and seeds/plant, seed index, seed yield/feddan and harvest index. In general, Sakha-1 recorded the higher seed yield/feddan compared to Nubaria3. The highest seed yield/ feddan were obtained from calcium application at 4 g/liter combined with Sakha-1 and time of applying calcium at 45 and 60 days.
