EFFECT OF TREATMENT WITH BIO-FERTILIZERS AND CHEMICAL FERTILIZERS IN: 2-SOME YIELD QUANTITATIVE CHARACTERS OF THREE VARIETIES OF OKRA

Abstract

Afield experiment was conducted during spring season 2015 in the Hibhib of Diyala province to study treatment effect of three varieties of okra, Ptira, Patra and Samara, by four types of bio-fertilizers which are without fertilizer (B0), Bionutrients (B1), Biohealth (B2), Endospor (B3) and two levels of chemical fertilizers (50% and 100% of the fertilizer recommendation) in the yield of quantitative characters. Split-split plot arrangement using randomized complete block design (R.C.B.D) was used with three replicates. Five traits were studied in this study which were: the early of yield, number of fruits in the plant, the weight of fruit, the yield of one plant and total yield. Tested moral differences between the means of the traits studied according to Duncan test polynomial and the level of probability of 0.05. The study demonstrated the superiority of cultivar Patra early quotient, number of fruits, the weight of fruit, the yield of one plant and total yield as well as the superiority of biofertilizer B3 in the number of fruits, the weight of fruit, the yield of one plant and total yield. The result also showed the superiority of 50% level of chemical fertilizer in number of fruits, weight of fruit, yield of one plant and total yield, and it was the triple interaction between the variety and bio-fertilizers and chemical fertilizer affected where the superiority of variety Patra the treatment bio-fertilizers (B3) and fertilized at %21 fertilizer chemical in most of the traits.
