EFFECT OF CHOSEN FERTILIZER TRETMENTS 0N GROWTH AND YILD OF TWO CHILI PEPPER VARIETIES Capsicum annuum L. UNDER UNHEATED PLASTIC HOUSE CONDITIONS

Abstract

The experiment was carried out in Basrah for the winter season of 2010 – 2011 under the condition ofunheated plastic house. The experiment included 10 factorial treatments in which two varieties of chili pepper,these are the Syrian variety Albaraa and the Dutch variety De Cayenne and 5 chosen fertilizer treatments whichwas 1- control treatment 2- poultry (7) ton/ha 3- (0.12) ton N/ha 4- poultry (7) ton/ha + (0.12) ton N/ha 5- poultry(14) ton/ha + (0.24) ton N/ha. Randomized complete block design was used in a factorial experiment and themeans were compared using Revised L.S.D. at 5%. The result showed that Albaraa was superior in the stemdiameter, leaves content of chlorophll and nitrogen, average fruit weight, and in length, diameter, thickness of thefruit , early plant yield (79.76) gm, plant yield (491) gm, early production (0.351) ton/ha and total productivity(2.16) ton/ha while De Cayenne was superior in the plant height, the number of main branches, total leavesnumber, leaf area, the percentage of the dry matter in leaves and fruits, percentage of potassium, floweringearliness, total number of flowers, percentage of fruits set, number of fruits and its content of chlorophyll,vitamin C , and in the percentage of protein. The treatments poultry (7) ton/a and poultry (14) ton/ha + (0.24) tonN/ha showed to be superior in most of the studied characteristics in comparison with other treatments. Theinteraction between varieties and fertilizer treatments was significant in all growth and yield traitss under study.
