The Effect of Adding Orgainc fertilizer in the development & Production of Both Pomegranate

Abstract

This study was conducted in Al-Anbar Province for the season of 2013, in Al-sofyya location, related to Al-Ramadi City near the Euphrates River, the study aims at studying the response of pomegranate trees of the both species "Saleemi" and "Wonderful" to different kinds of composts. Fifty-four trees of two-year old have been chosen from both species with replications planted with dimensions (4x4m). Two kinds of composts (horses and poultries) were used with three levels (0, 3, 6 kg.ltree-1) given the symbol (P0, P1, P2) for horses manure and (H0, H1, H2) for poultries manure. The composts were added on 171 mixed with soil with a depth of 30cm. Afactorial experiment was done (3x3x2) with three replications according to the Randomized Completed Block Design (R.C.B.D). The results have been as follows: 1-Difference in used cultivars did not show any significant impact on the stud ied traits except the fruit size which was the highest (156.3cm3) in Wonderful cultivar compared to the lowest fruit size (150.6cm3) shown by saleemi. 2-Appling both horses and poultry manures significantly affected all studied traits especiaiiy at the higher application level (6kg.lteer-1). 3-Using organic fertlilzer (horses and poulty manures) significantly reduced the nitrate concentration in both Wonderful and Saleemi which was 12.2 and 11.4 mgL-1 at H2 and P2 respectively compared to 15.5 and 14.4 mgL-1 recorded at no organic fertilizer applied (H0 an P0) respectively.
