1. INTERFERENCE OF OPERATING SPEED AND PHYSICAL PROPERTIES OF GRANULATED FERTILIZERS WITH THEIR DEPOSITION
ABSTRACT Uniformity in the deposition of granulated fertilizers in the seed furrow is essential for crop development and productivity. Quantitative (dose and flow) and qualitative factors (segregation and formulation) influence granulated fertilizer distribution throughout its application. This experiment aimed to compare the deposition of two granulated fer

3. EFFECT OF THE DISTANCE BETWEEN THE CUTTING DISC AND FURROW OPENERS EMPLOYED IN ROW CROP PLANTING ON SOIL MOBILIZATION
ABSTRACT The objective of this study was to determine the effect of the longitudinal distance between a cutting disc and a fertilizer furrow opener on the operational performance of the furrow opener working at different forward speeds during soil mobilization. The soil in the experimental area was classified as Typic Hapludalf with a loam soil texture. The

4. IRRIGATION WATER MANAGEMENT TECHNIQUES FOR LOWLAND FURROW-IRRIGATED SOYBEAN IN SOUTHERN BRAZIL
ABSTRACT Different water management strategies should be investigated to ensure adequate water supply to furrow-irrigated soybean plants in lowlands. This study examined the performance and efficiency of furrow irrigation techniques and related them to the soybean yield potential in lowland fields of Southern Brazil in the 2017/18 growing season. An experime

5. Amaranth in southernmost latitudes: plant density under irrigation in Patagonia, Argentina
ABSTRACT In Argentina there have been few evaluations of Andean pseudocereal plantings. This study explored the response of Amaranthus cruentus cv Mexicano to different plant densities under furrow irrigation in the lower valley of the river Negro, Patagonia, Argentina. The experimental design consisted of 3 blocks with randomized treatments (subplots), each

6. Tuber yield and economic result of ‘Atlantic’ potato in response to NPK fertilizer formulas
RESUMO A aplicação usual de altas doses do fertilizante NPK 4-14-8 nos sulcos de plantio da cultura da batata, independentemente da fertilidade do solo ou das necessidades nutricionais da cultivar, tornou-se um paradigma no Brasil. Contudo, a fórmula 4-14-8 nem sempre atende as necessidades da cultura e pode desequilibrar a disponibilidade de nutrientes n

7. Comparison of 15N isotope methods to determine the recovery efficiency of nitrogen from green manure
Resumo: O objetivo deste trabalho foi avaliar três métodos isotópicos de aplicação de 15N ao solo para determinar a eficiência de recuperação do nitrogênio derivado da adubação verde pelo milho (Zea mays). Utilizou-se o delineamento experimental de blocos ao acaso, com seis repetições. Os tratamentos consistiram de três métodos isotópicos de

8. Application methods of Azospirillum brasilense in first- and second-crop corn
RESUMO Objetivou-se verificar se a inoculação de Azospirillum brasilense via semente ou sulco de semeadura pode reduzir a necessidade de adubação nitrogenada no milho, em primeira e segunda safra. Os experimentos foram conduzidos, no município de Chapadão do Sul, MS, em primeira safra (2014/2015) e segunda safra (2016). Na primeira safra utilizou-se o

9. Red-Yellow Latosol Penetration Resistance Under Different Subsoiling Depths
ABSTRACT The objective of this work was to evaluate the penetration resistance (PR) of a red-yellow latosol submitted to two subsoiling depths for implanting a forest plantation. The subsoiling was evaluated at 40 cm (S-40) and 50 cm (S-50) of depth by determining the soil moisture and soil density, while soil PR was evaluated before and after subsoiling at

11. Azospirillum brasilense inoculation methods in corn and sorghum
RESUMO A inoculação de Azospirillum brasilense, normalmente, é realizada via semente. Entretanto, essa bactéria apresenta penetração passiva na planta, o que torna possível a inoculação das culturas utilizando-se outros métodos. Objetivou-se avaliar a influência de modos de inoculação de A. brasilense na emergência e crescimento inicial de milh

12. Sugarcane Root Development and Yield under Different Soil Tillage Practices
ABSTRACT New strategies for sugarcane production have been very important since the incorporation of ethanol in the Brazilian energy mix in the early 1970s. Prior to planting sugarcane, the soil is prepared, and this process can affect root development and, consequently, sugarcane production. This study was conducted in an area of sugarcane crop renewal in t
