THE main objective of this study was to produce safe and clean garlic crop.This study was carried out during 2014/2015 and 2015/2016 seasons at El-Kassasein region, Ismailia, Egypt, to investigate the effect of mineral NP fertilizers, biofertilizers and biochar on two garlic cultivars production grown in sandy soil conditions.Sids 40 cultivar recorded the highest neck and bulbdiameters, dry weight of plant parts, marketable and total yields/feddan, N and total protein contents in the bulbs. Fertilization of garlic with 75% NP + 3kg Nitrobein (Nr) + 2kg Phosphorein (Pr) + 3m3 biochar/fed.increased all plant growth characters and yields of grades 1 and 2, marketable, exportable and total/fed., while, with 50% NP + 3m3 biochar/fed.gave the lowest bulb nitrate content. Fertilizing the two cultivars with 75% NP + 3kg Nr + 2kg Pr + 3m3 biochar/fed.increased dry weights of plant parts, as well as yields and its components. Fertilizing Balady plants with 100 or 75% NP + 3kg Nr+ 2kg Pr + 3m3 biochar/fed. gave the highest net returns, followed by Sids 40 with 100% NP + 3kg Nr + 2kg Pr/fed., or with 100% NP + 3kg Nr + 2kg Pr + 3m3 biochar/fed. It could be concluded that fertilization of garlic plants with 100 or 75% NP + 3kg Nr + 2kg Pr+ 3m3 biochar/fed. can improve plant growth, yields and its components with a good bulb quality. Treated garlic plants with biochar positively enhanced plant growth, productivity, and bulb quality. Using previous treatments could reduce the costs, increase net return of garlic production and keep the environment out of pollution.
