Abstract

This research paper was carried out in the net house at the Central Laboratory for Agricultural Climate (CLAC), throughout two tested seasons of 2017/2018 and 2018/2019 to investigate the effect of using rice straw as a growing substrate (bale & ditch) on vegetative growth, yield and water use efficiency (WUE) of two cultivars of common bean (Phaseolus vulgaris L.), Hilda as indeterminate variety and Nebraska determinate variety compared to conventional cultivation in soil. Seedlings were cultivated at 1st September in two growing seasons. Study was included three treatments with 4 replicates arranged in a randomized complete block design. Results indicated that plants grown on ditch rice straw treatment as substrate reflected the highest positive effect on vegetative growth characters (plant length, number of leaves/plant and stem diameter), leaves mineral content of N. P. K and yield and its components (total yield/plant, and fiber content on pods) at both studied cultivars. While, the lowest negative effect on those characters was observed with bale rice straw treatment. Moreover, raised bed clay (control) treatment was replaced in second place after the treatment of ditch rice straw. In addition, cultivation into straw ditch consumed lower quantities of water than other treatments. Finally, straw ditch substrate may be recommended for increasing common bean productivity and decreasing water utilization beneath net house conditions.

Highlights

Common bean (Phaseolus vulgaris L.) is one of the foremost vital vegetable crops developed in all landmasses of the world, it's characterized with high protein, fiber, and complex carbohydrate substance [1]
The experiment was conducted during the autumn growing seasons of 2017/2018 and 2018/2019 at the experimental farm of Dokki site, Central Laboratory for Agricultural Climate (CLAC), Agricultural Research Center (ARC), Giza
From the Figure (1) it's clear during first 60 days of both growing seasons minimum air temperature was always higher than 20 °C, that is allow for both tested cultivars to grown strongly and gave a good vegetative growth

Summary

Introduction

Common bean (Phaseolus vulgaris L.) is one of the foremost vital vegetable crops developed in all landmasses of the world, it's characterized with high protein, fiber, and complex carbohydrate substance [1]. The foremost critical issues confronting common bean generation in Egypt is soil-borne pathogens, nematodes and soil saltiness. Almost 5 million tons of rice straw is delivered each year from the rice cultivated areas. No organized recycling process were utilized for this squander until presently. It causes genuine contamination when arranged by burning [5]. Within the final decades, burning as a transfer strategy for getting off straw is being decreased and more of rice straw is being utilized. The huge amounts of rice straw that delivered in Egypt (more than 5 million tons each year), the very cheap cost and the components of rice straw
