EFFECT OF CHEMICAL AND ORGANIC FERTILIZER ON THREE VARIETIES OF BROAD BEAN

The study was carried out in the field of vegetables Department of Horticulture and Land scap Design / Faculty of Agriculture and Forestry / University of Mosul / Iraq during the growth season 2017-2018 to study effect of two factors: the first three varieties of the broad been (Local, Turkish and French), the second three factors of the fertilizer is chemical fertilizer, and organic fertilizer with Atalopolina (400 kg. ha-1) and a mixture of organic and chemical fertilizers (1/2 chemical fertilizer + 200 kg. ha-1 of Atalopolina fertilizer) and control treatment (without fertilization). Implemented in the field using Split Plot Design within RCBD with three replication. The treatment of varieties was laid in the main plots and the fertilizers in the sub plots. The most important results can be summarized as follows: There was a significant difference between varieties, where the local variety significantly increased the plant height, Local and French varieties increased leaf area per plant and total yield of pods, the Turkish variety were significantly increased the seed weight per pod. As well as the chemical and organic fertilizers significantly increased number of branches per plant, biological yield, seeds weight per pod and total yield of pods, but chemical fertilizer significantly increased leaf area per plant, pod length and total yield of pods, chemical and control treatments increased average of pod weight. The results of interaction between factors showed that the local variety with chemical treatment significantly increased plant height, leaf area per plant, biological yield, yield of green seeds 5.91 t. ha-1 and total yield of pods 10.79 t. ha-1, but interaction between Turkish variety and control treatment significantly increased number of branches per plant and average of pod weight, the French variety with mixed the fertilizers increased dry matter of vegetative growth, and Turkish variety with mixed fertilizers increased number of pods per plant and seeds weight per pod, the French variety with chemical fertilizer increased pod length.
