COBERTURA NITROGENADA EM DIFERENTES ESTÁDIOS FENOLÓGICOS DO FEIJOEIRO COMUM ALTERA PRODUTIVIDADE E QUALIDADE DE GRÃOS

A necessidade de conhecer a marcha de absorção do nitrogênio (N) pelo feijoeiro é importante para compreender os desempenhos produtivo e qualitativo dessa cultura. O objetivo deste estudo foi avaliar a influência da cobertura nitrogenada em função de diferentes estádios fenológicos no desempenho morfoagronômico e produtivo e nas características tecnológicas dos grãos do feijoeiro em sistema de plantio convencional. Utilizou-se o delineamento de blocos casualizados, com quatro repetições. Os tratamentos foram constituídos por doze combinações de fornecimento de N (FN) em cobertura (dose total = 90 kg ha-1 de N) aplicadas nos estádios fenológicos V3, V4 e R5 (V3+V4+R5) do feijoeiro de inverno irrigado: 00+00+00; 30+30+30; 30+60+00; 30+00+60; 60+30+00; 00+60+30; 45+45+00; 00+45+45; 45+00+45; 90+00+00; 00+90+00; e 00+00+90. A fonte de N utilizada foi ureia convencional. Os FN 30+00+60, 00+45+45 e 45+00+45 incrementam a produtividade de grãos e a eficiência agronômica em relação à ausência de N e à aplicação de dose única no estádio fenológico V4. do feijoeiro comum. As maiores produtividades de proteína bruta e o menor tempo para cozimento foram proporcionadas pelos FN 00+45+45, 45+00+45, 90+00+00, 00+90+00 e 00+00+90.Palavras-chave: Phaseolus vulgaris; parcelamento do N; eficiência agronômica; tecnologia dos grãos. NITROGEN TOPDRESSING AT DIFFERENT PHENOLOGICAL STAGES ON COMMON BEAN CHANGES GRAIN YIELD AND QUALITY ABSTRACT: The need to know the nitrogen uptake (N) by common bean is important to understand the productive and qualitative performance of this crop. The objective of this study was to evaluate the influence of nitrogen topdressing as a function of different phenological stages on the morphometric and productive performance, and on the technological characteristics of the bean grains grown under conventional soil preparation. A randomized block design with four replications was used. The treatments were constituted by twelve topdressing N supply combinations (NS) (total dose = 90 kg ha-1 N) applied in the phenological stages V3, V4 and R5 (V3+V4+R5) of irrigated winter bean: 00+00+00; 30+30 +30; 30+60+00; 30+00+60; 60 + 30 + 00; 00+60+30; 45+45+00; 00+45+45; 45+00+45; 90+00+00; 00+90+00; and 00+00+90. The source of N used was conventional urea. NS 30 + 00 + 60, 00 + 45 + 45 and 45 + 00 + 45 increase grain yield and agronomic efficiency in relation to the absence of N and single dose application at V4 phenological stage of common bean. The highest crude protein yields and the shortest cooking time were provided by FN 00+45+45, 45+00+45, 90+00+00, 00+90+00 and 00+00+90.Keywords: Phaseolus vulgaris; N splitting; agronomic efficiency; grains technology.

Abstract: Among the factors that affect seedling emergence and crop establishment are seed germination and vigor, which has an important influence on the establishment of the initial plant population and development, and may affect crop yield. Based on this background the objective of this research work was to evaluate the effects of seed vigor of common bean seed lots and its effects on crop grain yield. The treatments consisted of six seed lots of common bean, which were composed by different combinations of high and low vigor seeds. Seed lots were assessed by germination and vigor tests (first count of germination, electrical conductivity and accelerated aging). A field experiment was conducted in a randomized block design, with plots of six lines of five meters and were evaluated for grain yield at harvest. It was concluded that seed vigor affects common bean grain yield; the use of low vigor seeds results in grain yield reductions of up to 20%.

The Impact

The impact of Rhizophagus intraradices (RI) interaction with phosphorus fertilization on the yield of Phaseolus vulgaris L. var. Negro Tacaná, and the N and P content in plant tissue and grain were determined. The experiment consisted of six treatments:1) Control, 2) RI, 3) 40 kg.ha-1 of P2O5, 4) RI + 40 kg.ha-1 of P2O5, 5) RI + 26 kg.ha-1 of P2O5, and 6) RI + 13 kg.ha-1 of P2O5, using a randomized block design with four replicates. Results probed that inoculation of plants with RI promoted a better health, growth and grain yield. In particular, grain yield inoculated with RI presented similar values as obtained with inorganic fertilization of 40 kg.ha-1 of P2O5, indicating that inorganic fertilization can be fully substituted by RI. The use of this technology provides an efficient use of soil nutrients, which is translated into a lower investment for producers.

Tillage System

To achieve better results in the no-tillage system (NTS), it is important to properly manage the cover crop prior to planting by using herbicides, usually glyphosate. The effect of glyphosate on plant coverage is slow, and plants take a few days to die completely. Thus, when applying the herbicide on the same day of planting soybean or corn, cover crops are still alive and standing, causing initial shading on seedlings of the crop and delaying its establishment. Therefore, this study aimed to evaluate the effect of distinct cover crops and their timing of desiccation prior to planting soybean or corn, on crop yield and yield components. Two experiments were installed, one for soybean and another for corn. Each experiment consisted in combining three cover crops (Brachiaria brizantha, common bean or millet) chemically desiccated at two timings before planting the crop (15 or 0 days before planting) under no-tillage system (NTS). Experiments were installed in a completely randomized block design with five replications. Brachiaria brizantha produced the highest amount of biomass; common bean and millet as cover crops allowed higher soybean grain yields; herbicide application under common bean, millet and Brachiaria brizantha 15 days before planting soybean allowed higher crop grain yields; desiccation timing of common bean did not affect corn grain yield; Brachiaria brizantha should be desiccated 15 days before planting corn to allow maximum grain yield; when millet was used as a cover crop, glyphosate application at planting of corn allowed the highest grain yield.

ABSTRACT Due to the socioeconomic importance of common bean in Brazil, studies that allow establishing favorable conditions for not compromising the crop with white mold, in view of the enormous damages caused by this fungus, become vital to Brazilian agriculture. Therefore, the aim of this study was to evaluate the incidence and severity of white mold in common bean (Phaseolus vulgaris L.), cultivar ‘Madrepérola’, subjected to different irrigation intervals, planting densities and fungicide application. The research was conducted in Viçosa-MG, Brazil, in the years 2011 and 2012. The statistical analysis used the split-split-plot scheme. The fungicide applications (with or without fungicide) were allocated to plots, the irrigation intervals (3, 6, 9 and 12 days) to sub-plots and planting densities (6, 9, 12 and 15 plants per linear meter) to sub-subplots, in a randomized block design with three replicates. The variation of the irrigation intervals did not contribute significantly to the control of white mold. It is recommended to use lower planting densities in order to minimize the damages caused by the disease. The use of the fungicide was the main method of white mold control in two consecutive years.

Nitrogen Rates

Trinexapac-ethyl spraying time and proper nitrogen rate are essential to reduce plant height and lodging at harvest, without affecting rice yield and nutritional balance. This study aimed to evaluate trinexapac-ethyl spraying time and N contents as topdressing for upland rice paddies. The experiment was carried out in a randomized block design and a 4x5 factorial scheme, with four replications. Treatments consisted of four trinexapac-ethyl spraying times, in the phenological stages of tillering, floral differentiation, between tillering and floral differentiation, and a control (without spraying), and five nitrogen rates (0, 50, 100, 150, and 200, kg ha-1) as topdressing. As nitrogen topdressing rates increased, leaf contents of N, Fe++, and Zn++ increased, while S and Mn++ decreased; however, contents of P, Ca++, Mg++, B, and Cu++ were little influenced. When trinexapac-ethyl was applied, leaf contents of N, P, S, B, and Zn++ were little influenced, while P, Ca++, Mg++, Fe++, and Mn++ increased, and Cu++ decreased. Trinexapac-ethyl can be applied at tillering without decreasing rice yield. Upland rice increased grain yield by 58 and 46% in two consecutive crop years due to application of about 120 kg N ha-1 as topdressing.

A field experiment was conducted in the central farm, Regional Research and Technology Transfer Station, Coastal Zone OUAT, Bhubaneswar during kharif 2020 using cv-Lalat variety of Rice. The experiment was laid out in randomized block design (RBD) with ten treatments and three replications. In this experiment BOF (Basic Oxygen Furnace) slag was used as a source of silica for application to rice crop. 200, 300 and 400 kg SiO2/ha was applied in combination with 50% STD and 75% STD in order to assess the efficacy of Silica with reduction in fertilizer dose by 50% and 25%. It was shown in case of grain yield, straw yield, and harvest index, 100% STD (T4) registered maximum (36.9q/ha) grain yield which was 29.4% more than that of control. Of course, grain yield in case of T9i.e., 75% STD+300kg SiO2/ha was at par 36.2q/ha indicated efficacy of silica application by reducing fertilizer dose. Harvest index was not significantly affected by Si treatments. However, maximum HI (0.478) was observed in T9. Available N, P, K and S status in post-harvest soil was increased significantly due to application of silica along with fertilizer over control indicated better availability of nutrients which plays a vital role in increasing production and productivity of rice. The content and uptake of N, P, K and Si was significantly increased over control due to application of silica with fertilizer. Though 100% STD (T4) was found to be very effective as compared to other treatments but 75% STD+300kgSiO2/ha was also equally effective so far as yield, yield attributing characters, available nutrient status, N, P, K and Si content and uptake along with Relative Agronomic Efficiency (RAE), Agronomic Efficiency (AE), Apparent Recovery (%) AR and Production Efficiency (PE) are concerned.

Abstract: The objective of this work was to evaluate the efficiency of molten and ground alkaline potassium-silicate rocks (K1) and of ground phonolite rock (K2) as sources of potassium for upland rice (Oryza sativa) and common bean (Phaseolus vulgaris) crops, in comparison with the traditional source (KCl). Two experiments - one with each crop - were conducted on a Typic Haplorthox in a randomized complete block design with four replicates. The treatments consisted of three sources (KCl, K1, and K2) and four rates (0, 20, 40, and 80 kg ha-1 K2O) of K. Regardless of the used source, K fertilization increased the leaf K content and grain yield of the upland rice and common bean crops. The agronomic efficiency index (AEI) of the alternative K sources varied according to the crop. For upland rice, the AEI of K2 was 8% higher than that of KCl at the recommended K rate, but similar at the highest rate. For common bean, the AEI values of K1 were close to that of KCl at the rates of 40 and 80 kg ha-1 K2O. The alternative sources K1 and K2 supply K and increase the grain yield of common bean and upland rice, respectively, similarly to KCl.

Environmental Stratification

The objectives of the present work were to identify common bean lines with high grain yield, adaptability and stability; stratify the environment; and detect the most important factors for the genotype by environment (G×E) interaction in northeastern Brazil. Nineteen experiments were conducted in a randomized block design with three replications during the rainy growing season at 11 locations in the States of Pernambuco, Alagoas, Sergipe, and Bahia in 2009 and 2010. In each experiment, 16 “carioca” seeded lines were evaluated, and the grain yield, assessed. Data were subjected to analyses of variance and adaptability and stability by the methodologies of Annicchiarico and Additive Main Effects and Multiplicative Interactions (AMMI), analysis of the factors for environmental stratification and joint analysis with decomposition of the G×E interaction in genotype by year and genotype by location. According to the AMMI method, BRS Estilo and CNFC 11951 were selected as stable high-yielding lines. CNFC 11954, IPR Juriti, CNFC 11948 and BRS Estilo were identified as stable high-yielding lines based on the methodology of Annicchiarico. BRS Estilo was identified as stable according to both methodologies and was therefore considered suitable for growth in the Northeast region for use as a parent line in regional breeding programs. The locations in this region used to test the common bean lines were informative, except Carira, which could be eliminated from the assay network. Interaction among genotypes, locations and years were observed, suggesting that assessments shoud be conducted at the largest number of locations and years, in this order of importance.
