EFFECT OF DIFFERENT COMPOST TEA ON ZINK, IRON AND PHOSPHORUS CONCENTRATION AND UPTAKE IN WHEAT abstract
Venniwash is lateral product of vennicomposting process which contains nitrogen,phosphorous and many micronutrients, h01mones; etc.The purpose of this study was evaluating methods of compost tea on Zn, Fe and P content in wheat plant. A green house experiment was conducted in a factorial randomizes complete block design (RCBD) with four replicates.
