Abstract

This experiment was carried out during the winter seasons of 2018/2019 and 2019/2020 at El-Khattara Experimental Farm, Faculty of Agriculture, Zagazig University,Sharkia Governorate, Egypt, to study the effect of vermicompost, botanical compost and mineral nitrogen fertilizers on growth, productivity and bulb quality of garlic.The treatments were arranged in a randomized complete block design with three replicates. Results showed that fertilizing garlic plants with 3 ton/feddan of vermicompost+20 m3/feddan of botanical compost+100% of recommended mineral nitrogen increased plant height, leaf number, neck and bulb diameters, bulbing ratio, bulb weight, number of cloves/bulb, dry weight of bulb and leaves, total dry weight/plant and total yield/feddan. Also, this treatment led also to an increment of N, P and K contents in leaves, bulb and plant, total protein and dry matter contents, while the lowest value of nitrate content in cloves was obtained by using vermicompost at 3 ton/feddan+ botanical compost at 20 m3/feddan in both seasons of the study.

8 of 10 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
