Abstract
Taro ~Colocasia escu/enla L. Scholll is a monocotyiedonous plant belonging to the family (Araceace). II is considered one of the most important vegetable grown in Egypt due to its high nutrilional and economical values. Local cullivar (8a/ady) has been put under investigation to study the effect of different levels of (F~rmyard manure) (40,80 and 120 m3/Fed). two bio fertilizers. I.e (nitrobein. phosphor in) and potasseln foliar spray during 2000 and 2001 years. on plant growth. yiel and its components as well as chemical constituents in Corms. In general. all the studied charactes were better in plants receiving FYM levels. Increasing the applied FYM rate from 40 to 120m3/Fed. significantly increased most parameters. Moreover he best results were obtained by using potassein foliar spray compared with nitrobein and phosphorein. The application of FYM (120m3/Fed) combined with potassein foliar spray increased total yield/Fed by 18.97 and 23.31 ton/Fed in 2000 & 2001 years. respectively. The same combinatlon gave the highest dry weight. Fertiliz tion of 120ml/Fed FYM with nitrobein and 80 m3/Fed with potassein were the optimum rates 10 maximize corms dry weight. The obtained data indicted that application of FYM or potassien foliar spray caused significant increase of starch, protein and NPK in the corms. While potassien and nitrobein treatments didn·t show a significant effect on protein and starch percentage. Applying nltrobein gave hIgher phosphorus per enlage and phosphoreln gave the highest potassium percentage.
