Manejo de aplicação de níquel e magnésio na cultura do feijoeiro comum irrigado

Abstract

This research investigates the effects of foliar fertilization with magnesium and nickel on bean crops. The experiment was carried out at Fazenda Santo Antônio, located in Araguaiana – MT, with geographic coordinates of 15°36"41"S and 51°48"13"W, covering an area of 119 hectares destined to the cultivation of pinto beans under center pivot irrigation. The region has a climate classified as Aw, with annual precipitation of 1,750 mm and average annual temperature of 24 °C. The soil is of the typical Dystrophic Red-Yellow Latosol type. The experiment used a randomized block design with four replications, sub divided. The application of magnesium sulfate and nickel sulfate as nutrient sources occurred on the 13th and 26th day after planting, using a knapsack sprayer. Applications were performed at two stages of plant development, including the vegetative stage. The study examines the impact of these nutrients on different stages of plant growth, shedding light on their influence on various growth variables such as plant height, number of pods per plant, pod size, number of kernels per pod, thousand weight grains and total yield. The results reveal that the choice of fertilizer dosage and timing plays a key role in optimizing bean crop yields. Treatments involving magnesium sulfate and nickel sulfate, applied separately or in combination, demonstrate positive effects on both crop yield and grain quality. Statistical analysis indicates variability in the data, emphasizing the importance of considering factors such as soil conditions and agricultural management practices. These findings contribute significantly to our understanding of bean plant nutrition and serve as a basis for improving agricultural practices aimed at maximizing the production of high-quality bean.
