Response of soybean plant to calcium and potassium foliar rates in sandy soil
|
|
Abstract: Soybean plants were cultivated in a sandy soil at Ismailia Agriculture Research Station farm at the (summar season of 2004). Plants sprayed with three foliar rates (0, 150 and 300 mg Ca++ or K+ /L.) two times; after 30 and 45 days from sowing. Plant samples from all treatments were taken twice at 60 and 90 day ages. At harvest, seed yield was recorded. Calcium and potassium was determined in the plant tissue in seeds.
Increasing calcium and potassium foliar application rates from zero to 300 mg/l increased dry weight of shoot and root successively. Also increasing calcium and potassium rates up to 300 mg/l increased significantly Ca and K-content % of shoot and root. The rate of 300 mg/l calcium and potassium increased obviously the grain yield of soybean over the two other treatments. Increasing the rate of each of calcium and potassium rate increased its content of soybean grain
