Abstract
This experiment was carried out during two successive winter seasons of 2008/2009 and 2009/2010 at EL-Khattara Experimental Farm, Faculty of Agriculture, Zagazig University, Sharkia Governorate, to study the effect of farmyard manure (FYM), elemental sulphur (S) and their interactions on growth, plant chemical composition and yield and its components as well as sulphur use efficiency (SUE) of garlic plants under sandy soil conditions.
Addition of 30 m3FYM / fed. recorded maximum values of total dry weight / plant, chlorophyll a, b and total chlorophyll (a+b) , N, P and K uptakes by different plant organs and total uptake by plant, yields of grades 1 and 2, exportable , marketable and total yield/fed. as well as average bulb weight of garlic plants.
Obtained results indicated that application of S at the rate of 200 kg /fed. recorded maximum values of dry weight of roots, bulb, leaves and total / plant, total uptake of N, P and K by plant, yields of grades1, 2 exportable , marketable and total yield/fed as well as average bulb weight of garlic plants, whereas S at 100 Kg/fed increased chlorophyll a,b and total (a+b) in leaf tissues and sulfur use efficiency.
The interaction between FYM at the rate of 30 m3/fed. 200 kg S/fed. significantly increased total dry weight / plant , P content in roots, N and P in bulb and N,P and K contents in leaves, uptakes of N,P and K by roots, bulb and leaves as well as total uptakes of N,P and K by plant, yields of grades 1,2 and 3, exportable , marketable and total yield/fed., as well as, average bulb weight, whereas the interaction between FYM at 20 m3/ fed and S at 100 Kg /fed increased sulpher use efficiency.
