1. Precision Tillage Operations: Analyzing the Efficiency of Conventional and Robotic Systems ABSTRACT. The crop production sector is labor- and energy-intensive, significantly impacting the environment. Soil tillage is one of the most expensive and polluting technological operations; therefore, modern automated and precision technologies applied according to soil variability can help change economic costs and environmental pollution. This study evaluated the effects of site-specific variable depth tillage using two combinations of a conventional tractor and a multifunctional cultivator,... E. Šarauskis, S. Sokas, I. Bručienė, S.

2. Relationship Between Soil Classes and Grape Yield in a Vineyard of the Campanha Gaúcha Region Brazilian 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.

3. Assessing Metering and Spreading Performance of Drones (UAVs) for Application of Dry Materials Along 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 Download paper
4. Temporal Variations in Leaf Nutrient Concentrations and Photosynthetic Nutrient Use Efficiency in Durian This 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
