Autonomous Inter-Row Hoeing using GPS-based side-shift Control
Several developments and investigations have been done to automate the lateral control of hoes with the aim to achieve higher weeding efficiency and decreased labor costs. The aim of this project was to investigate the accuracy and limitations for a computer controlled hoeing operation based on a GPS system. A conventional hoe and an electro-hydraulic side shift frame was used and attached to a...
متن کاملBenefits of Precision Farming Technologies for Mechanical Weed Control in Soybean and Sugar Beet—Comparison of Precision Hoeing with Conventional Mechanical Weed Control
Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technolo...
متن کاملEffects of ground cover from branches of arboreal species on weed growth and maize yield1 Efeitos da cobertura do solo com ramos de espécies arbóreas no crescimento das plantas daninhas e rendimento do milho
Cultivating maize under systems of alley cropping results in improvements to the soil, a reduction in weeds and an increase in yield. Studies using ground cover from tree shoots produce similar results. The aim of this study was to evaluate the effects on weed growth and maize yield of ground cover made up of 30 t ha-1 (fresh matter) of branches from the tree species: neem (Azadirachta indica A...
متن کاملIntegrated Weed Management Studies for Autumn Planted Maize
A field experiment was conducted to evaluate the integrated effect of weed control practices on the weed control efficiency, growth and yield of autumn planted maize (Zea mays L.) under agroecological conditions of Faisalabad. Treatments comprised manual hoeing and earthing up alone and in combination with metolachlor + atrazine @1110+740 g a.i.ha; manual hoeing + earthing up, metolachlor + atr...
متن کاملEffects of spacing and post-planting treatments on survival and growth of Fraxinus angustifolia seedlings.
This study was conducted at a bottomland hardwood site with heavy textured soil in Akyazi, Turkey to determine the effect of initial spacing (3.0 x 3.0, 3.0 x 2.0, 2.5 x 1.6 and 2.5 x 1.2 m) and post-planting treatments (untreated check, moving, hoeing, disking, and hoeing plus disking) on early survival and growth of Fraxinus angustifolia Vahl. One-year old bare-root seedlings (70 +/- 5 cm in ...
