Development and evaluation of four-wheel tractor-attached multi-crop planter for mechanized seeding of maize in the Philippines CIGR Journal
PASCUAL, KRISTINE Samoy; Rafael, Marvelin L; Remocal, Alaissa T; Regalado, Manuel Jose C.
The use of a multi-crop planter (MCP) attached to a compact 4-wheel tractor (4WT) is still not yet fully explored in the Philippines, despite the popularity of 4WT for land preparation in maize areas. A 4WT-attached MCP was developed for row seeding of rice, maize, and mungbean. This study evaluates the MCP adaptive model for maize in a field experiment and on-farm trials at two farmers’ fields during dry season. The MCP with seed metering plate having seven 12-mm diameter holes and 3-mm thickness had a seeding rate of 18.9 kg/ha which is within the targeted design range (15–20 kg/ha), a field capacity of 0.14 ha/h and field efficiency at 78%  in well-tilled-clay soil under controlled condition. In farmer’s fields, the MCP delivered seeding rates within...

Plant spatial arrangement affects grain production from branches and stem of soybean cultivars Bragantia
Ferreira,André Sampaio; Zucareli,Claudemir; Werner,Flavia; Balbinot Junior,Alvadi Antonio.
ABSTRACT Phenotypic plasticity is the ability of plants to undergo changes in morphology and yield components to adapt themselves to distinct environmental conditions. The knowledge on the changes in yield components of branches and stems at varied plant spatial arrangements needs to be updated due to recent changes in soybean production system. Thus, this study aimed to evaluate the yield components of branches and stems, as well as to assess the share of these plant parts in the total grain yield of soybean cultivars with indeterminate growth type, under different spatial arrangements. The experiment was conducted during the growing seasons of 2013/2014 and 2014/2015, under a randomized complete-block design and in a4 × 3 × 2 factorial scheme with three...
