1. Relationship Between Soil Classes and Grape Yield in a Vineyard of the Campanha Gaúcha RegionBrazilian viticulture has shown significant expansion in recent decades. However, this productive growth has brought new challenges for vineyard management, particularly regarding the understanding of soil spatial variability and its relationship with grape yield and quality. The objective of this study was to correlate the spatial variability of soil classes with grape yield. The study was conducted in a commercial vineyard located in Santana do Livramento, in the Campanha Gaúcha region,... B. Baumgardt, B. Trevizan Paese, J.M. Moura Bueno, G. Brunetto, A.A. Kokkonen, A.

2. Assessing Metering and Spreading Performance of Drones (UAVs) for Application of Dry MaterialsAlong with pesticide applications, the use of UAVs (also commonly referred to as drones) for applying dry materials has increased rapidly in the United States. Currently, various types of product metering and spreading systems are available on commercial drones for applying dry materials. However, limited information is available on their application performance, especially the metering accuracy and the uniformity of distribution across the swath. Therefore, research studies were conducted to... S. Virk, E. Ward, J. Sizemore |
3. Temporal Variations in Leaf Nutrient Concentrations and Photosynthetic Nutrient Use Efficiency in DurianThis study assessed leaf nutrient concentration in durian leaves and evaluated the photosynthetic use efficiency of nitrogen (N), phosphorus (P), and potassium (K) on durian trees over two fruiting seasons. This study also provided nutrient recommendations for durian fertilization using the Diagnosis and Recommendation Integrated System (DRIS) and optimal nutrient management range. A total of 63 mature trees were selected for leaf sampling. All samples were collected at two growth stages in each... M.F. Omar, S.K. Balasundram, N.E. Tajidin |
