Effect of Foliar Application of Micronutrients and Compost Tea on Chemical Composition and the Productivity of Fenugreek Plants Under Baloza - North Sinai Conditions

Micronutrients are important for plant growth, but plants need relatively small amounts of them, hence, the term "micro. The present investigation was carried out at Baloza Research Station of the Desert Research Center, North Sinai, Egypt during the two successive seasons of 2017/2018 to study the effect of foliar application combination of micronutrients forms and compost tea. The experiment was conducted in a split plot design, with three replicates. The main plots were randomly assigned to compost tea (with, without), the sub plots were represented by four micronutrients spraying of Fe, Cu, Mn and Zn, as (the two chelated forms of humic and EDTA and the mineral form). The objectives of the present study were to investigate the effect of foliar application of some chelated micronutrients and compost tea on growth and yield productivity of Fenugreek plant and macro and micro nutrient contents in herb and seed. The results showed that, the best treatments were ((Mn,Zn,Cu,Fe) Humic form with compost tea  which gave the highest yield components: the average percentage increment of dry weight of  seed ( g/ plant), dry weight of  seed( kg/ fed.),  fixed oil (ml/ plant) and fixed oil( kg/fad.) (76.80, 77.62, 122.08 and 137.9) in two season, respectively. In addition,  macro and micro elements contents were significantly increased in herb and seeds. These results also indicated that the concentrations of Fe, Mn, Zn, Cu in seeds and herb, of Fenugreek plants were lower the normal ranges.
