Response of peanut to foliar spraying with copper and calcium under different levels of potassium fertilization in sandy soils [electronic resource].

Includes references.

Two field experiments were conducted during 200 I and 2002 seasons in the Agricultural Fann of Suez Canal University at Ismailia to study the effect of three levels of potassium fenilizer i.e. 35, ~~ and 75 kg K20/ fad, three concentrations of chelated calcium (12 % Ca-EDTA) i.e. water (control), 850 and 1700 ppm and two concentrations of sequestreted copper (13 % Cu) namely water (control) and 500 ppm on yield. its components and yield quality of peanut Giza 6 variety in sandy soils of Ismailia Governorate. Application of potassium fenilizer up to 75 kg K20/fad significantly increased plant height. number of branches. pods and seeds/ plant, weight of pods and seeds/ plant, 100-seed weight. seed oil content (%) and pod, seed, straw, biological and oil yields/fad. Spraying peanut plants with chelated calciwn up to 1700 ppm resulted in significant increases in plant height, seed oil content (%) and pod. seed, straw, biological and oil yields! fad as well as all yield attributes except number of seeds! pod.
