Treatment of Snap Bean Plants Grown Under Sandy Soil Conditions With Some Natural Materials and Its Relation to Growth, Yield and Pod Quality

Abstract

Two field experiments were carried out during the fall seasons of 2012 and 2013 at the

Role of Humic Substances and Compost Tea in Improvement of Endogenous Hormones Content, Flowering and Yield and its Components of Faba Bean (Vicia faba L.)

“…Maximizing yield due to soil drench application of compost tea and humic acid can be correlated with direct and indirect positive effects on plant growth, nutrients availability and hormones content which, in turn, diverts more photo-assimilates towards higher number of sinks. Positive effects of organic substances on yield were previously reported by compost tea application (El-Gizawy et al, 2013), humic acid (Waqas et al, 2014) as well as compost tea and humic (Khafaga et al, 2014 andEl-Sayed et al, 2015) as compared to the untreated plants.…”

“…This reflects increase in plant growth and photosynthesis. Various publications have indicated the importance of humic acid(Ahmed et al, 2010) as well as compost tea and humic acid(El-Sayed et al, 2015) on improving plant growth parameters and chlorophyll content.…”

Effect of Some Bio-Stimulants and Packaging Material on Quality Attributes of Snap Beans during Storage and Shelf Life Conditions

“…It enhances soil fertility and improves physical, chemical and biological properties of soils (Mikkelsen, 2005), and increases the availability of nutrient elements and consequently affected plant growth, yield and quality (Gad El-Hak et al, 2012). Snap bean pods obtained from plants treated with humic acid had significantly surpassed those pods obtained from untreated plants (control) in minimizing pod weight loss %, and gave higher score of general appearance and maintaining total carbohydrate % and protein % in pods and gave the minimum values of fiber percentage in pod during storage (El-Sayed et al, 2015).…”

“…Effective microorganisms (EM) are a commercial bio-fertilizer that contains a mixture of co-existing beneficial microorganisms collected from natural environments that are used as a soil amendment (Woodward, 2003). Snap bean pods obtained from plants treated with EM gave lower weight loss percentage, higher score of general appearance and maintaining protein % and total carbohydrate % of pods during storage (El-Sayed et al, 2015).…”

“…Pre-harvest plant nutrition is a major factor influencing fruit and vegetable quality (Sams, 1999). Increasing the productivity of snap bean pods with high quality and good storability is considered an important aim that could be achieved through using some biostimulants, viz., seaweed extract (Abou El-Yazied et al, 2012), humic acid (Gad El-Hak et al, 2012) and effective microorganisms (El-Sayed et al, 2015).…”
