“…According to Fageria et al (2011) andViana et al (2011), N and P are the nutrients that promote more response to grain yield increase in common bean. Moreover, the CNFC 15873 and CNFC 15875 genotypes accumulated nutrients faster than the others.…”

There is a lack of researches that evaluate the development and nutrient accumulation in super early genotypes of common bean for the elaboration of fertilization programs. This study aimed at characterizing the development; N, P, K, Ca and Mg accumulation by leaves; grain yield; and yield components of super early genotypes of common bean. Field experiments were conducted in a randomized blocks design, with four replications. The treatments consisted of the IPR Colibri (control), CNFC 15873, CNFC 15874 and CNFC 15875 genotypes. Plants were sampled throughout the common bean development, being divided into leaves, stems and pods. After determining the dry matter, the contents of N, P, K, Ca and Mg accumulated in leaves were estimated. At harvesting, the grain yield and yield components were evaluated. The biomass accumulation in stems and leaves occurred until the flowering stage, and then it started in the pods until harvesting. The genotypes that absorbed more nitrogen and phosphorus had a higher grain yield. The average growing season of super early genotypes was 70 days (winter) and 63 days (summer). CNFC 15874 was the most productive genotype in the winter, with grain yield similar to the IPR Colibri cultivar (control). In the summer, CNFC 15873 and CNFC 15875 achieved grain yield similar to the IPR Colibri cultivar.

“…This can be associated with excess nutrients, because the sewage already contains nutrients ( Figure 2B). Viana et al (2011) observed a quadratic effect on bean performance relating to nitrogen (N) and phosphorus (P) concentrations; N was tested at 0, 70, 140, and 210 kg ha -1 and P 0, 100, 200, and 300 kg ha -1 of P 2 O 5 . The highest productivity (1,528 kg ha -1 ) was obtained with 98 kg ha -1 of N and 201 kg ha -1 of P, emphasizing that there is a limit to these relationships; above that value, yielded decreases.…”

Considering the relevance of the reduction or replacement of fresh water supplies for irrigation, to mitigate the use of agricultural fertilizers and to improve sustainability, this study aimed to evaluate water and nutritional efficiency of treated sewage in cowpea plots. The experiment was conducted in the city of Tianguá-CE, on land belonging to the Water and Sewage Treatment Company of Ceará. It used a randomized block design for the arrangement of split plots. The plots contained two water sources (treated sewage and well water). The subplots contained four irrigation levels based on potential evapotranspiration (50%, 75%, 100%, and 125% of ETc) and the sub-subplots contained four nitrogen, phosphorous, and potassium (NPK) levels (0%, 33%, 66%, and 99% of the nutritional recommendations for cowpea cultivation). The yield variables, number of pods per plant, bean numbers per pod, and bean production, were improved with increased irrigation, regardless of the water source. Examining NPK levels in particular, yields differed depending on the water source. The use of treated domestic wastewater for bean irrigation can replace up to 100% of commercial fertilizers.

“…Arf et al (2012) and Teixeira et al (2000) observed similar results at 80 kg ha -1 and 150 kg ha -1 respectively for the Perola cultivar. Similarly, Viana et al (2011) found 14 pods per plant using 108 kg N ha -1 for the Carioca cultivar.…”

“…Similar results were found in a study conducted by Gomes Junior et al (2008), which found a linear relationship between yield and nitrogen level up to 120 kg N ha -1 for two dry beans cultivars under no-till planting and corn stover studying two dry beans cultivars. Viana et al (2011), which also explored the relationship between N and dry beans yield (carioca cultivar), found the largest yield under a 98 kg N ha -1 fertilization scheme in an area that was tilled before planting. According to Teixeira, Andrade, Carvalho, Morais, and Corrêa (2000), three main traits explain the increase in dry beans yields: number of pods per plant, number of grains per pod, and 100 grains weight.…”

In order to identify the contribution of yield components to the final yield of dry beans, two widely adopted cultivars (IAC Milênio, and IPR Tuiuiú) were evaluated under nitrogen fertilization levels (0, 50, 100 and 150 kg N ha-1) in a crop-livestock system. Experiments were conducted under a randomized complete block with three replications design during two years (2016 and 2017) which were split in two cropping phases. A subplot factorial scheme of grazing heights by nitrogen fertilization (grains crops or pasture) was used. Dry beans crops were fertilized during the summer and yield components evaluated along with yield measurements. Descriptive and Pearson’s correlation coefficient analyses were performed and followed by path analysis to explain the interrelationship between yield components (explanatory traits) and yield (main trait). For IAC Milenio in 2016 cultivated as a second crop the main trait influencing yield the number of seeds per plant through direct and indirect effect of other traits, regardless of the topdressing nitrogen level applied. In 2017, a greater number of significant correlations was found for the IPR Tuiuiú cultivar. The number of pods per plant was the trait that affected yield most all nitrogen levels.
