The Utilize of Vermicomposting Outputs in Substrate Culture for Producing Snap Bean

The need for increasing the agricultural area to secure food production and the sustainability under the climate change impacts and current conditions of Egypt, especially the shortage of available water and soil were the driving forces for developing ecology substrate culture via using vermicomposting outputs. The study was carried out at Central Laboratory for Agricultural Climate (CLAC), Giza, Egypt under unheated double span plastic house during two successive autumn seasons of 2012/2013 and 2013/2014 for investigating the effect of vermicompost as substrate amendment mixed with perlite or sand in different proportions 0, 10, 20 and 30 % of substrate combined with three sources of nutrient solutions (compost tea, vermi-liquid and chemical) on the growth and yield of snap bean cv. Alhamma in split plot design with four replicates. Data revealed that increasing vermicompost rate from 0 to 20 % had positive significant effects on vegetative growth, yield and quality of snap bean pods while increasing the rate up to 30 % had no subsequent effect. Sand + vermicompost (80: 20 v/v) followed by perlite + vermicompost (80: 20 v/v) recorded the highest results of the vegetative growth characteristics during the two successive seasons compared to other treatments. The highest values of early and total yield / m
