Influence of Compost, Humic Acid and Effective Microorganisms on Organic Production of Red Cabbage

Abstract

 AN EXPERIMENT was conducted during the two successive ……winter seasons of 2012/2013 and 2013/2014, in the experimental farm of Arid Land Agricultural Research and Service Center (ALARC), Fac. of Agriculture, Ain Shams University, Cairo, Egypt. The present work aims to study the influence of humic acid and effective microorganisms (EM) on organic production of red cabbage (Lisa F1 Hybrid) under sandy soil conditions. The rates of compost (100 and 150% as recommended dose of nitrogen) with and without additions of humic acid and effective microorganisms (EM) individually or in combinations, were investigated comparing to recommended dose of NPK as mineral fertilizer (control) on growth, yield and quality of red cabbage. The results showed that the rates of 100 and 150% compost + humic acid + EM and 150% compost + EM only gave significantly superior in growth, yield and some quality of red cabbage compared to recommended dose of NPK as mineral fertilizer. It is recommended that good organic production of red cabbage in sandy soil can be performed successfully using rate of 150% of compost plus EM with or without addition of humic acid or using 100% compost plus humic acid and EM.
