Effect of water quantity and farmyard manure on garlic under sandy soil conditions [electronic resource]: I. dry weight and plant chemical composition.

Includes references.

This experiment was carried out during two successive winter seasons of 2000-200] and 2001-2002 at EL-Khattara Experimental Farm, Fac. Agric., Zagazig Univ., to study the effect of water quantity, farmyard manure and their interactions on dry weight and plant chemical composition of garlic under sandy soil conditions. Obtained results indicated that water quantity at the rate of 2600 m³/fed recorded maximum values of dry weight of roots, bulb, leaves and total , plant, free and total water in leaves and total uptake of N, P and K by plant. Meanwhile, water quantity at 600 m Ifed led to increase chlorophylls, carotenoids, prolein and bound water in leaf tissues. Addition of 30 m3FYM 'fed recorded maximum values of total dry weight , plant and both free and total water in leaf tissues. Whereas, FYM at 45 m³/fed recorded maximum concentration of all leaf pigments and total N, P and K uptake' plant. FYM treatments had no significant effect on bound water, in the second season only and prolein content in leaf tissues. The interaction between 2100 or 2600m3 !fed and 30 or 45 m3 FYMlfed significantly increased total dry weight , plant .Garlic plants irrigated with 2100 m3lfed and fertilized with FYM at 45m3lfed gave the highest Nand K content in bulb and leaves, respectively. Also the interaction between 2100 or.2600 m3lfed and 45 m³FYM/fed significantly increased total uptake of Nand K 'plant.
