The biological and useful yield of Phaseolus vulgariscv. ‘Banja’ and cv. ‘Diacol Nima’ were compared when sown at populations, in row spacings, equivalent to 5–4–32–3 plants m~2, at four levels of fertility achieved by the use of zero, five, ten and 20 cwt ae-1 respectively of a fertilizer mixture containing by weight 2:2:1 calcium ammonium nitrate, single superphosphate and muriate of potash. Yield and its components were determined at final harvest. The two cultivars behaved generally similarly. Crop Index, while highest in the plants with no fertilizer, was more or less constant for each cultivar over a wide range of biological yields in those plants receiving fertilizer. Yield is determined to the extent of 85–7% and 86–1% respectively for 'Diacol Nima’ and ‘Banja’ by the product of pods/plant and plants surviving to harvest. High densities, although giving the highest grain yields, are wasteful of seed in that the percentage of plants surviving to contribute to yield is much reduced.

Abstract. AquaCrop is a crop simulation model developed by the FAO aimed at assessing the yield response to water supply. Once the model is calibrated and validated, it is a useful tool to simulate crop yields under different management options or climatic and soil conditions. Until now, AquaCrop has not been parameterized for dry beans ( L.), and thus our objective was to calibrate and validate the model for this crop using experiments performed 40 years ago at Davis, California. A set of parameters derived from the calibration with one irrigation experiment was used to validate the model using five experiments carried out in 1977 and 1978 that had treatments vastly differing in irrigation depth and frequency. Yield predictions over a wide range of values (<1 to 3.5 t ha-1) were very good, with RMSE of 0.16 t ha-1 and Willmott’s d of 0.978. Seasonal ET was also accurately predicted by the model (RMSE = 40 mm, d = 0.930), as also evidenced by comparing the lysimeter measured ET of 489 mm against the lysimeter simulated ET of 501 mm. Canopy cover and the time course of biomass were adequately simulated as well. Even though total soil water extraction was well simulated, the simulated soil water distribution with depth differed from measured values in the dryland treatment. We conclude that AquaCrop can now be used for the simulation of dry beans in different environments, and we emphasize the value of carefully conducted field experiments for the validation of crop simulation models.

A adubação nitrogenada e a irrigação são manejos necessários determinantes para uma boa produtividade. É necessário evitar o uso indiscriminado de adubos e dos recursos hídricos, utilizando técnicas agronômicas que diminuem os impactos socioeconômicos e ambientais. O estudo sobre a viabilidade econômica do feijoeiro é importante para definir gastos futuros, minimizar utilização de recursos naturais e aumentar a produção. O objetivo deste estudo foi avaliar economicamente a produção de feijão (cultivar BRSMG Majestoso) sob diferentes lâminas de irrigação e doses de adubação nitrogenada. O experimento foi conduzido no Instituto Federal do Triângulo Mineiro – Campus Uberaba. Foram utilizados quatro níveis de déficits de água no solo (15, 30, 45% e um fator sem déficit hídrico) e quatro doses de nitrogênio (50, 100, 150 e 200 kg ha-1), com quatro repetições, em blocos casualizados. Foram realizadas análises da eficiência econômica da lâmina de água e do custo de produção de feijão em função da adubação nitrogenada. Após estudo dos déficits, tanto a lâmina ótima econômica (446,6 mm) quanto a lâmina física (448,9 mm) encontradas, foram semelhantes e proporcionaram produtividades similares. O maior rendimento bruto foi de R$ 7.653,99 quando aplicado 100 kg ha-1 de nitrogênio. Palavras-chave: água; déficit; adubação; Phaseolus vulgaris L.; economia.   Economic viability of bean, under irrigation blades and nitrogen doses   ABSTRACT: Nitrogen fertilization and irrigation are necessary management determinants for good productivity. It is necessary to avoid the indiscriminate use of fertilizers and water resources, using agronomic techniques that reduce socioeconomic and environmental impacts. The study on the economic viability of beans is important to define future spending, minimize the use of natural resources and increase production. The objective of this study was to economically evaluate the production of beans (cultivar BRSMG Majestoso) under different irrigation depths and nitrogen fertilization doses. The experiment was conducted at the Federal Institute of Triângulo Mineiro - Campus Uberaba. Four levels of soil water deficits (15, 30, 45% and one without water deficit) and four nitrogen doses (50, 100, 150 and 200 kg ha-1) were used, with four replications, in randomized blocks. Analyzes of the economic efficiency of the water depth and the cost of bean production were carried out as a function of nitrogen fertilization. After studying the deficits, both the economic optimum blade (446.6 mm) and the physical blade (448.9 mm) found were similar and provided similar productivity. The highest gross yield was R$ 7,653.99 when 100 kg ha-1 of nitrogen was applied. Keywords: water; deficit; fertilizing; Phaseolus vulgaris L.; economy.

Recently, nanofertilizers are being tested as a new technology, either for soil or foliar applications, to improve food production and with a reduced environmental impact. Nano calcium phosphate (NCaP) was successfully synthesized, characterized and applied in this study. A pot experiment was carried out in two successive seasons in 2016 and 2017 on (Phaseolus vulgaris L.) plants to obtain the best phosphorus treatments. The results were applied in a field experiment during the 2018–2019 season. Single superphosphate (SSP) at 30 and 60 kg P2O5 fed−1 and NCaP at 10%, 20% and 30% from the recommended dose were applied to the soil. Foliar application involved both monoammonium phosphate (MAP) at one rate of 2.5 g L−1 and NCaP at 5% and 10% from the MAP rate. The results of all experiments showed that NCaP significantly increased the shoot and root dry weights, the nutrient content in the shoot and root, the yield components, the nutrient concentration and crude protein percentage in pods of the snap bean plants compared with traditional P. The greatest increase was obtained from a 20% NCaP soil application in combination with a 5% NCaP foliar application. The present study recommends using NCaP as an alternative source of P to mitigate the negative effects of traditional sources.

Dry bean (Phaseolus vulgaris L.) is one of the most important pulses consumed in the world. Total phenolic content, total flavonoid content, total monomeric anthocyanin content and antioxidant capacity were determined, using ferric reducing antioxidant power and free radical scavenging activity, in 255 lines grown under the same environmental conditions. For all parameters analysed, there was a wide range of variability, with differences always above one order of magnitude. Phenolic compounds in beans with coloured coats were found to be more efficient antioxidants than those with completely white coats, and samples with more strongly coloured coats (red, cream, black, pink and brown) showed the highest antioxidant capacities. Based on the strong correlation detected between the variables, total phenolic content can be considered an appropriate indicator of antioxidant activity. The results provide a robust database for selecting those lines of greater functional and nutritional interest in terms of cultivation for direct consumption, for inclusions in food formulations or for use in future breeding programs.

El poroto común (Phaseolus vulgaris L.) es una leguminosa originaria de América y representa un componente importante en la dieta de la población latinoamericana por su alto contenido en proteínas y carbohidratos. El poroto cultivado se originó de los porotos silvestres, que son plantas anuales, herbáceas y trepadoras, que se distribuyen desde el norte de México hasta el noroeste de la Argentina. Estudios basados en caracteres morfológicos, bioquímicos y moleculares revelaron que tanto dentro de las variedades cultivadas como de las silvestres existen dos acervos génicos principales, uno Andino y el otro Mesoamericano. Las provincias del Noroeste Argentino (NOA) albergan un gran número de porotos silvestres y de variedades locales tradicionales (primitivas o “landraces”) mantenidas durante años en un sistema de cultivo tradicional. Sin embargo muchas de estas poblaciones están en peligro de extinción debido a las presiones de explotación forestal y pastoreo existentes en la zona, por lo que resulta de fundamental importancia su recolección y estudio. En esta tesis se analizó la variabilidad genética de un grupo de poblaciones silvestres y primitivas de poroto común del NOA, recolectadas en diferentes sitios de las provincias fitogeográficas de las Yungas, Prepuna y del Chaco, entre los 1300 y 2900 msnm, utilizando marcadores bioquímicos (proteínas de reserva de las semillas: faseolinas) y moleculares (RAPD e ISSR).
