Effect of irrigation water amount and potassium fertilization on fodder beet yield and yield components under new reclaimed sandy soil conditions
Abstract: Two field experiments were carried out at Ismailia Agricultural Research Station (IARS) under new reclaimed sandy soil conditions by using drip irrigation system during 2000/ 2001 and 2001/ 2002 winter seasons, to study the effect of irrigation water amounts and potassium fertilization rates on yield and yield components of fodder beet (Beta vulgaris L). Three irrigation amounts: 1840, 2300, and 2760 m3/ fed/ season were applied and four potassium rates: 0.0, 48, 72 and 96 kg K2O/ fed were studied.
The obtained results indicated that yield of fodder beet was increased by increasing the amount of irrigation water, and potassium rates singly or in combination. The fresh yield of roots was significantly increased by 17.1 and 19.8 % and the fresh yield of leaves increased by 27.9 and 50.8% when 2300 and 2760 m3/ fed were applied, respectively, compared to 1840 m3/ fed application. Increasing irrigation water also increased dry yields of both roots and leaves. In addition potassium fertilization increased root fresh yields by 17.5, 26.8 and 29.2 % of the control as 48, 72 and 96 kg K2O/ fed were applied, respectively. Regarding leaves fresh and dry yields, the maximum yield was obtained with 72 kg K2O/ fed treatment, a slight yield drop was observed with increasing K dose above that level. Increasing the amount of irrigation water significantly increased N and P contents, total protein and total carbohydrates of both roots and leaves. However, a negative correlation was observed between irrigation and K contents of both roots and leaves. On the other hand, increasing potassium fertilization rates resulted in significant increments in NPK, protein content as well as total carbohydrates of roots and leaves of fodder beet crop
