Conteúdo: |
The genotypic differences on growth and yield of common bean (Phaseolus vulgaris L.) in response to P supply were evaluated in a field experiment under biological N2 fixation. Eight cultivars were grown at two levels of applied P (12 and 50 kg ha-1 of P ¾ P1 and P2 respectively), in randomized block design in factorial arrangement. Vegetative biomass was sampled at three ontogenetic stages. The effects of genotype and phosphorus were significant for most traits, but not the genotype phosphorus interaction. The cultivars presented different patterns of biomass production and nutrient accumulation, particularly on root system. At P1, P accumulation persisted after the beginning of pod filling, and P translocation from roots to shoots was lower. The nodule senescence observed after flowering might have reduced N2 fixation during pod filling. The responses of vegetative growth to the higher P supply did not reflect with the same magnitude on yield, which increased only 6% at P2; hence the harvest index was lower at P2. The cultivars with highest yields also presented lower grain P concentrations. A sub-optimal supply of N could have limited the expression of the yield potential of cultivars, reducing the genotypic variability of responses to P levels. |

In the agricultural sector, using lower quality water sources has increased in irrigation practice. Thus, this review summarizes the consequences of using brackish and/or saline water in irrigated agriculture, highlighting some effects on soil and plants in general. Water quality for irrigation and the salinity tolerance threshold of forage species with productive potential for semiarid regions are also discussed. Between January and June 2022, a systematic search was carried out for studies that evaluated the quality of water for irrigation, the effects of using water with excess salts on the soil and on plants in general, and on forage species with productive potential in semiarid regions. The databases consulted were: ScienceDirect, Scopus, Wiley Online Library, Web of Science, Taylor and Francis, and Scholar Google. A total of 1567 studies were found. Of these, 200 studies were reviewed and 154 were used because they met the review objective. The forage plants reported here have salinity tolerance ranging from low to moderate. The management adopted, as well as the species used, are factors that influence the performance of the crop under stress. Although they are widely cultivated in arid and semiarid regions of the world, few studies still show the salinity threshold of these crops, mainly for forage cactus, sunflower, and pigeon pea species. Therefore, it is essential to carry out more research on this topic in order to provide information that improves the management of production systems in saline environments around the world.
