“…In this case, the highest total N and K content occurred at the beginning of fruit development, while the highest total P content was detected at the final stage of fruit development, mainly in 'Champaka' and 'Smooth cayenne'. This can be related to the amount of dry matter produced or to the nutrient concentration in the plant tissue (Ávila-Escobedo et al, 2022). In the cv.…”

Background. The amount of nutrients required by pineapple varies depending on the cultivar and planting density. Knowing the nutrient requirement in quantity and the appropriate phenological stage will allow the development of an adequate fertilization program. Objective. To determine the effect of pineapple cultivar and planting density on N, P, and K content during plant development and at harvest. Methodology. The cultivars 'Smooth Cayenne', 'Champaka', and 'MD-2' were established at 30000, 45000, and 60000 plants ha-1. Eight samples were taken to determine the N, P, and K content in the organs and the total plant. Results. The highest and lowest N, P, and K contents were detected in the leaf and root, respectively. The highest N and K contents occurred at 441 - 506 days after planting. Higher P content occurred close to harvest. The highest N, P, and K contents per plant were at 30000 plants ha-1 (14.86, 1.52, and 16.29 g plant-1, respectively) and the lowest at 60000 plants ha-1 (10.16, 1.13, and 14.6 g plant-1, respectively). Higher N, P, and K contents per hectare were detected with 60000 plants ha-1 (609, 68, and 875 kg ha-1, respectively). At harvest, ‘Smooth Cayenne’ at 60000 plants ha-1 accumulated the highest amount of N, P, and K (147, 37, and 306 kg ha-1, respectively). Implications. The changes that can occur in the nutrient requirements of pineapple as a function of cultivar, planting density, and stage of plant development were identified. This information will be useful for producers, agricultural technicians, and researchers in Mexico and the world, to generate fertilization programs or establish new research. Conclusion. At the beginning of plant growth, a higher N, P, and K contents in the leaf, this amount decreases as the fruit harvest approaches. Regardless of cultivar, the highest nutrient content per plant occurs at the lowest planting density, however, the highest content per hectare occurs at the highest planting density. At harvest time, fewer nutrients are removed from the soil with 'Champaka' and 'MD-2' fruit.

Cover crops can increase agricultural sustainability by protecting soil from erosion, increasing biodiversity, and symbiotically incorporating fixed nitrogen (N) into the soil. Nowadays, however, in Uruguay mostly grasses are planted in autumn to protect the soil from erosion. Another option is to study tropical legumes’ performance as cover crops, which can fix substantial amounts of nitrogen in short growing periods, thereby bridging the knowledge gap in Uruguayan agriculture. The main objective was to evaluate and compare the performance of six tropical legumes (Crotalaria juncea, Crotalaria spectabilis, Crotalaria ochroleuca, Cajanus cajan, Dolichos lablab, Mucuna pruriens) and the temperate legume Glycine max. The evaluation focused on aboveground biomass and the N mass derived from fixation (NmdFix), as well as other attributes; three field experiments were conducted on a southern Uruguay farm during the summers of 2017, 2018, and 2019. The growing cycle lengths for the cover crops in 2017, 2018, and 2019 were 117, 130, and 90 days, respectively. The results showed that when planting was done at late December (2017 and 2018 growing cycles), the species with the highest mean biomass yield were Crotalaria juncea (two year average 12.0 Mg ha-1) and Cajanus cajan (11.0 Mg ha-1), but Cajanus cajan (149 kg ha-1) more than doubled the NmdFix mass of Crotalaria juncea (57 kg ha-1). In 2018 biomass yields were much higher than in 2017, with Glycine max (20.0 Mg ha-1) yielding at a similar level to Crotalaria juncea and Cajanus cajan (20.5 and 18.7 Mg ha-1, respectively). Amounts of NmdFix, however, were much higher in Glycine max and Cajanus cajan (263 and 253 kg N ha-1, respectively), than in Crotalaria juncea (91 kg N ha-1). In 2019 planting had to be delayed until early February and only Glycine max maintained acceptable biomass and NmdFix levels. In conclusion, based on its fixing N potential, for late December sowings Cajanus cajan and Glycine max would be the most promising species for cover crop use, while for late January or early February sowings, only Glycine max would an option because the tropical species seriously impaired their productivity when grew longer into the cooler autumn temperatures.
