Nine localities were selected by their tradition in the bean cultivation in order to carry out a survey and diagnose of the situation of this productive activity. Based on surveys and visits to properties of farmers, it was that in the majority of the localities prevailed the use of Creole varieties. Creole varieties with a major commercial use were important for their precocity. A longer vegetative cycle of the improved varieties was a disadvantage which caused grain deterioration during the rain season. Quality and seed availability were the main problems. Inoculants of Antracnosis was found in the field and in the seeds. Web blight was an important pathogen affecting bean crops followed by leaf spot anthracnose. It was found that weeds were an important problem in the Brunca region.

Several studies about web bligh control were carried out in Panama, the Dominican Republic, and Costa Rica. The pathogen´s genetic variability, bean varietal tolerance, chemical control, and sowing densities were evaluated. In Panama yield was increased through Benomyl applications and a greater sowing density. In the Dominican Republic Rhizoctonia AG 4, AG 2 2 and AG 1 groups were found. Several bean genotypes were evaluated, as well as populations from the web blight tolerant JB X MUS 14 cross. Between 20% and 40 % web blight severity was found in Costa Rica. Coverage and application of chemicals improved bean yield.

Meso-american and Andean eommon bean genotypes were inoeulated with mycellium of Thanatephorus cucumeris (Frank), Donk to determine: 1- The interaction among different isolations of Rhizoclonia solani, Kuhn and bean genotypes from two genetic pools, 2- the heritability of resistance to web-blight and 3- the existing genic completion between the meso-american and Andean pools, respeetively. The results found in this experiment were as follows : the strains vary depending of the origin site. Thus, the Dominican Republic and Colombian strains cause a lesser damage to the bean plants. The Panama # 1 isolation is moderately slow, and the Panama # 2 and Costa Rica caused the largest damage to the crop. The RS- 32-Cr strain was the most virulent of all. The heritabiJity shown by crossing was high which indieates that there is genic completion between the meso-ameriean and the Andean pools, respectively. The erossing of of AFR-251 x BAT-1155, in a direct and reciprocal way, showed differences in the F1 and the F2, indicating that the resistance to the disease is controlled by cytoplasmie genes as by nuclear genes. The type of resistance shown by the different evaluated crosses was horizontal and not vertical resistance.

Important Cash Crop

Haricot bean (Phaseolus vulgaris L.) is an important cash crop and protein source for farmers in many parts of Ethiopia. However, its production is limited by phosphorus fertilizer. Therefore, field experiment was conducted at the Malle woreda in Koybe kebele farmers training center during the main rain season of 2016 to investigate the responses of haricot bean to different levels of phosphorus fertilizer and its effect on growth, and bean yield. Four phosphorus rates (0, 23, 46, and 69kg ha-1) were used as treatments were laid out in a randomized complete block design with three replications. Red Wolaita haricot bean variety was used as planting material. Recommended rate of N (46 kg/ha) was applied to all treatments. The effect of phosphorus was significantly (P less than 0.05) increased bean yield and growth parameters such as leaf area and number of branches per plant, whereas its effect was not significant on plant height. Based on result obtained, application of 46kg P ha-1 is recommended for better production of haricot bean at Malle woreda and similar areas which have the same soil property.
