Handling Practices

The common bean, Phaseolus vulgaris L., is one of the most important sources of protein in Ethiopia and other developing countries. However, the Mexican bean weevil, Zabrotes subfasciatus (Boheman), is a major constraint of stored common bean that causes qualitative and quantitative losses. This study was conducted to assess farmers’ knowledge and perceptions of Mexican bean weevil, to examine farmers’ pest management practices, and to identify challenges of pest management practices to develop integrated pest management (IPM) strategies. A survey of 148 smallholder common bean farmers was conducted at Mareka and Loma districts in southern Ethiopia. The majority (75%) of the farmers stored common bean in polypropylene bags while less than 10% of the farmers stored beans in ‘Diya’ (a traditional storage structure). Most (60.8%) farmers stored their beans in seed (threshed) form, and the majority (63.5%) of them stored their beans for 3-5 months. The majority of the farmers had knowledge about the Mexican bean weevil; they could identify damaged seeds based on the ‘holes’ on the seed (72.3%) and circular ‘windows’ on the seed (20.0%). About 45% of the farmers mentioned the high amount of loss at the time of storage. In addition, most farmers (53.4%) estimated 26-50% loss in storage. Most farmers reported the use of pesticidal plants for control of Mexican bean weevil, while only a few farmers reported they had applied insecticide in their store. Education level and family size had a positive and statistically significant impact on the use of pesticidal plants for the control of Mexican bean weevil. Furthermore, education level also influences the use of chemical insecticide. Results highlighted the need to use improved storage technology and to train farmers in postharvest handling practices as a component to develop IPM approach in order to minimize losses occurring along the value chains of the common bean.

AbstractCommon bean (Phaseolus vulgarisL.) is amongst the most important grain legume crops in Africa in general, and Ethiopia in particular. The Mexican been weevil (Zabrotes subfasciatusBoheman) heavily attacks the grain of common bean. A total of 300 common bean entries were subjected to a ‘no-choice’ test at Melkassa Agricultural Research Centre, Ethiopia, using a randomized complete block design with three replications, to evaluate for resistance to the Mexican bean weevil. Data on insect and seed traits were collected and a significant level (P<0.01) of variation in all parameters measured was observed amongst genotypes. Relative resistance was recorded in landraces, improved genotypes and breeding lines, but the resistant genotypes, RAZ-11, RAZ-36, RAZ-2, RAZ-44, RAZ-120, RAZ-40 and MAZ-203, showed consistently complete resistance, with zero index of susceptibility value. Two other promising entries were also identified from the breeding lines (SCR-11) and landrace collections (NC-16) of Ethiopia. Stratified ranking diagrams showed that accessions from different eco-geographical origins in Ethiopia and those with different colours showed different patterns of response to infestation. The Ethiopian bean breeding programme should take up the resistant genotypes for a comprehensive yield trial at the national level and direct release them as commercial varieties. The incorporation of bean weevil resistance genes into adapted varieties through backcross breeding techniques, supported with marker assisted selection, seems to be the best strategy not only in terms of time saving but also in terms of effectiveness and efficiency.

Abstract This study aimed to evaluate the nutrition and yield of common bean according to the application of different doses of organomineral formulations (OMF), using filter cake as a basic organic compound in the presence and absence of nitrogen. The experiments was implemented and conducted in June "autumn/winter season" and November "rainy season" of the 2018 e 2018/2019 harvest, respectively. A randomized block design was used in a 6 x 2 factorial scheme, with four replications. The treatments were composed of six organomineral formulation doses: (0, 30, 60, 90, 120, and 150 kg ha− 1), with and without the addition of a nitrogen dose of 40 kg ha− 1, using urea as the mineral source. It was concluded that the organomineral fertilizer based on filter cake showed greater absorption of macronutrients N and K, an increase in the 100-grain weight, number of grains per pod, number of pods per plant, and grain yield in comparison with the absence of fertilization or mineral fertilizers, highlighting the doses of 90 and 150 kg ha− 1. The use of OMFs is a viable alternative with great potential for soil fertilization in agricultural production, besides the environmental sustainability generated by their inclusion in the production cycle of common bean.

The objective of this research was to evaluate the efficiency of different sources of residues in the composition of organomineral fertilizers on common bean yield. The experiment was carried out in a greenhouse at the Federal University of Uberlândia. A randomized complete block design was used in the 2 x 4 + 2 factorial scheme corresponding to two organic sources (biosolids and filter cake) and four doses of pelletized organomineral fertilizer (50, 75, 100 and 125% of the recommendation for common bean, plus two additional treatments without fertilization and fertilization with mineral fertilizer). The plant height and stem diameter were evaluated at 30 days after sowing (DAS), and an average number of pods plant-1 and grains pod-1, yield (g plant-1), dry mass (g), and mass of 1000 grains (g) at 84 DAS. The organomineral fertilizer based on biosolids fertilizer provides the largest growth with the use of 100% of the recommended dose, the largest volume of dry mass up to 75% and the highest yield at 50%. The organomineral fertilizer based on filter cake increased dry mass volume. The organomineral fertilizers evaluated have the potential to substitute exclusively mineral fertilization in the common bean crop.

Abstract. Beans are a staple component of human diet. However, grain storage for consumption is difficult due to pest attack. The objective of the present study was to conduct a survey of insects acting on the beans Phaseolus vulgaris L. and Vigna unguiculata (L.) in commercial stores in Porto Velho, Rondônia, Brazil. Samples were collected in small, medium-sized, and large markets. Percent infestation and weight loss caused by insects was evaluated during nine weeks. For V. unguiculata, 3.70% infestation was recorded from store PT 7 and the medium-sized market; the most serious situation occurred on the fifth week, when infestation reached 2.93%; weight loss was recorded from PT2 and PT7, with 19.19 g and 23.57 g. For P. vulgaris, infestation reached 3.70% in material from PT6; in small markets, infestation attained 0.84%; on the ninth week, 1.29% was recorded; weight loss from insects infestation occurred in samples from PT1 and PT6, 18.50 g and 9.78 g. Insect species found were Callosobruchus maculatus (Fabr.), Zabrotes subfasciatus (Boh.) and Acanthoscelides obtectus Say. Insect infestation did not significantly differ between both bean species.Levantamento dos Insetos que Atacam os Grãos de Feijão Armazenado Vigna unguiculata (L.) e Phaseolus vulgaris L.em Porto Velho, Rondônia, BrasilResumo. O feijão é um componente fundamental na alimentação dos seres humanos. Entretanto, o armazenamento dos grãos para consumo se torna uma enorme dificuldade devido ao ataque de insetos. O presente estudo teve como objetivo realizar um levantamento de insetos que atacam feijão armazenado Phaseolus vulgaris L. e Vigna unguiculata (L.) em estabelecimentos comerciais de Porto Velho, Rondônia, Brasil. As amostras foram coletadas em mercados de pequeno, médio e grande porte, nas quais foi avaliado o percentual de infestação e perda de peso ocasionado pelos insetos durante nove semanas. Para V. unguiculata PT 7 registrou 3,70% de infestação, o mercado de médio porte atingiu 3,70%, a 5ª semana foi a mais agravante alcançando 2,93% de infestação, já a perda de peso ocorreu em PT2 e PT7 sendo 19,19 g e 23,57 g. Para P. vulgaris a infestação em PT6 chegou a 3,70% , em mercados de porte pequeno a infestação resultou em 0,84%, na 9ª semana observou-se 1,29%, em relação a perda de peso por infestação de insetos ocorreram em PT1 e PT6, sendo de 18,50 g e 9,78 g. As espécies de insetos encontradas foram Callosobruchus maculatus (Fabr.), Zabrotes subfasciatus (Boh.) e Acanthoscelides obtectus Say,em ambas as espécies de feijão não houve diferença significativa em relação as infestações pelas pragas.
