Abstract
from the above mentioned results it was noticed that, fertilization with chicken manure, biofertilizer application and spraying with yeast extract gave total fresh and dry yield/fed. over than fertilization with chemical fertilizer alone. from the economical and environmental point of view, it was noticed that, fertilization with chicken manure in combination with seed inoculation with Rhizobium and mycorrhiza in the presence of spraying with yeast extract recorded net return over the chemical fertilizer treatments (control) and gave safety and clean products from the pollution which could be occur by excessive chemical fertilizers. Therefore, it can be recommended to use chicken manure in combination with seed inoculation with biofertilizer in the presence of spraying with yeast extract to improve yield and quality of pea plants
