Summary: This study investigated the influence of location and plant covering on the nutritional and sensory characteristics of early potatoes after oil-frying. The results showed that the application of a plant cover significantly increased the dry matter, starch, and sugar content of potato tubers in the second season. Sensory analysis revealed no differences in oil-fried potatoes grown with or without a plant cover. The study suggests that by employing a plant cover or choosing a warmer planting location, one can reach the desired level of potato maturity in less time without compromising yield or quality.

Summary: This study investigated the impact of water availability and nitrogen fertilization on plant growth, nutrient dynamics, and soybean crop yield. The results showed that water deficiency and absence of nitrogen fertilization decreased the accumulation and partitioning of various nutrients in plants. Although nitrogen fertilization led to increased nitrogen accumulation in tissues, it did not enhance yield significantly, while the highest seed yields were observed in plants under full irrigation regardless of nitrogen supplementation. However, deficient irrigation reduced the seed oil content in nitrogen-fertilized plants. In conclusion, nitrogen fertilization is crucial for nutrient homeostasis, and water availability affects biomass and nutrient accumulation, thus limiting soybean yield performance.

Summary: Environments with short growing seasons and variable climates can affect crop growth adversely. This study found that grafting rootstocks can enhance tomato performance under suboptimal soil temperatures, with decreased root hydraulic conductivity and conductance, but increased root-to-shoot ratios. Some commercial rootstocks have traits that maintain better rates of stomatal conductance and shoot N content, contributing to improved plant establishment and performance under suboptimal soil temperatures.

Summary: Proper irrigation and fertilization are crucial for achieving high yield and quality in potato production. This study investigated the impact of irrigation and nitrogen fertilization on potato yield, quality, and water use efficiency. Results showed that irrigation had a greater influence on potato yield and growth than nitrogen levels. Full irrigation with 300 kg N ha(-1) resulted in the highest total tuber yield, while low irrigation treatments led to significantly lower yields. However, the 66% field capacity irrigation treatment consistently had the highest water use efficiency.

Summary: This study evaluated the soil and water losses and storage root yield and quality of cassava planted in the dry and rainy seasons using conventional tillage (CT) and no-tillage (NT), following sole maize cropping or maize-palisadegrass intercropping. The results showed that NT following maize-palisadegrass intercropping can effectively reduce soil and water losses without affecting cassava yield and quality. Therefore, it is recommended to use maize-palisadegrass intercropping followed by NT for cassava cultivation in the rainy season to improve soil conservation.

Summary: This study evaluated the effect of different phosphorus doses on the yield and quality of sweet potatoes grown in tropical sandy soils. The results showed that increasing phosphorus doses did not increase yield and decreased starch concentration in areas with high phosphorus availability. In areas with low phosphorus availability, moderate phosphorus doses resulted in higher yield and starch concentration. Therefore, phosphorus fertilization should be adjusted based on the initial phosphorus concentration in the soil in different soil types.

Summary: Nitrogen is the most important nutrient for potato and cassava crops, and Azospirillum brasilense can enhance their growth. Field experiments were conducted to investigate the effects of A. brasilense inoculation and mineral nitrogen application on plant growth, nitrogen uptake, and leaf nitrogen concentration in both natural and disinfected soil. The results showed that inoculating A. brasilense increased leaf nitrogen concentration in potato plants, but did not significantly improve plant growth or nitrogen uptake. However, in cassava, A. brasilense inoculation increased leaf nitrogen concentration and shoot biomass, especially when nitrogen was supplied. In disinfected soil, A. brasilense inoculation also increased cassava nitrogen uptake. Conversely, in natural soil, A. brasilense minimized the negative effects of excessive nitrogen on cassava tuber development. These findings suggest that A. brasilense may be a more effective option for improving nitrogen status and growth in cassava compared to potato.

Summary: This study evaluated the effects of growing season on the structural, morphological, and physicochemical properties of sweet potato starches. The results showed that starches isolated from plants grown in the rainy season had a more ordered structure, higher gelatinization temperatures, thermal stability, and resistant starch content. Starches from plants grown in the dry season had a higher percentage of small granules, lower crystallinity, and lower gelatinization temperatures. These findings can help the supply chain plan and target suitable markets for naturally modified sweet potato starches.

Summary: The application of zinc fertilizers in the soil is a common practice in agriculture to address zinc deficiency in plants, aiming to increase productivity and/or nutritional quality. This study examined the effects of zinc sulfate fertilization on plant growth, yield, and nutrient accumulation in cassava plants. The results showed that soil fertilization with ZnSO4 improved yield, with an optimal dose of 2.5 g pl-1. Nutrient uptake in plant parts was favored at lower doses of zinc fertilizer, with maximum points ranging from 0.8 to 3.2 g pl-1 for macronutrients and 1.6 to 3.6 g pl-1 for micronutrients. Furthermore, the Zn content in tuberous roots increased by more than 40% with fertilization up to 2.8 g pl-1, enhancing the nutritional value of the roots.
