INFLUENCE OF SOME AGRICULTURAL PRACTICES ON SEED YIELD OF COMMON BEAN (Phaseolus vulgaris, L.)

Abstract

Seeds of legumes are extremely important crop plants which are widely cultivated in Egypt. Climate changes are the most important challenge facing agriculture today. Two field experiments were conducted at the Horticulture Research Farm Elbaramon during 2010 and 2011 seasons to determine the effect of different seeding dates and the plant distribution system on growth, yield and quality of common bean (Phaseolas vulgaris L. cv. Nebraska). The treatments were three sowing dates 20 Feb., 10 and 30 March and four plant distribution systems, i.e., 5 and 10 cm plant spacing on one or both sides of the row. The plant length, number of leaves, number of branches, the grain yield, number of seeds per pod, dry weight of seeds per pod, 100 seeds weight, biological yield, harvest index and chemical analysis of bean seed were affected significantly by sowing dates and the plant distribution system. The highest values of all these characters were recorded on 10 March and the lowest values of them were recorded on 30 March. Among four plant distribution system highest value of seed yield was obtained in 5 cm plant spacing on two sides and the lowest value was measured in 10 cm on one side. Further, sowing common bean seeds on 10 March with 5 cm on two sides had the best results for seed yields under the same conditions.

First Report: Metabolic and Molecular Evidence for the Detection of the Pathogenic Pseudomonas aeruginosa on Common Bean Seeds and Its Control Via Chitosan-silver Nanocomposite

“…The protein-rich seed is an excellent substitute for animal protein and is therefore considered an alternative to meat in developing countries. In addition, the leaf is also used as a vegetable and the straw as fodder (Moghazy, 2014). Being a member of the leguminous family Fabaceae, Phaseolus species are distinguished by their ability to hold atmospheric nitrogen through the symbiotic relationship between their roots and the nitrogen-fixing bacteria rhizobia (Peralta et al, 2016).…”

Effects of Co-Inoculation of Rhizobium and Plant Growth-Promoting Rhizobacteria on Common Bean (Phaseolus vulgaris) Yield, Nodulation, Nutrient Uptake, and Microbial Activity under Field Conditions

“…Although this legume has been grown for many years in the Nile delta and Nile valley, little is known about the population diversity of symbiotic N 2 -fixing rhizobia specific to this crop (Moawad et al, 1998). According to the statistics of the Egyptian Ministry of Agriculture in 2011, the area devoted for dry seed yield was about 21033 feddans, which is producing a total of about 29634 tons, with an average yield of 1.336 tons fed -1 (Moghazy, 2014). However, common bean is considered a poor fixer of atmospheric N compared with other crop legumes, and generally responds poorly to inoculation with Rhizobium under field conditions.…”

Response of Snap Bean Plants to some Treatments under Temperature Stress Conditions

“…The best temperature range for growth is (21 -27 o C). Average temperatures below 10 o C greatly decreased plant growth and maturity, while temperatures above 32 o C during holding flowers may cause a high percentage of flowers drop, thereby decrease crop production and quality (Moghazy, 2014). Likewise, seaweed extract has increased protein contact in root and shoot system, total soluble sugar and chlorophyll contact in leaves (Khan et al, 2009).…”
