Abstract (Summary)

Developing countries face challenges when it comes to planting agricultural crops. Planting by hand, a common method of planting in developing countries, is not very efficient and can limit yields. With the OSU Hand Planter, subsistence farmers can improve their planting methods and agricultural practices thus improving grain yields. This device aids in removing chemically treated seeds from the farmer’s hands, which is critical to prevent health hazards. In addition, it assists by providing a simpler means of applying fertilizer to the soil on a plant-by-plant basis, and decreasing soil erosion through improved plant-stand-homogeneity (Dhillon et al., 2017). This study was conducted to look into the impact of misses from the OSU Hand Planter on maize grain yield. Misses can be described as the failure of a seed to drop when a hand planter strike is made. This experiment evaluated percent misses of 0, 10, 20, and 30% at two populations of 49,400 and 74,100 seeds per hectare. Data were collected at Efaw and Lake Carl Blackwell in Stillwater, Oklahoma during the 2019 growing season. It was found that the percent of misses in this experiment had no statistical significant impact on grain yield levels at alpha levels 0.05 and 0.01, however differences were noted in Normalized Difference Vegetation Index (NDVI) readings throughout the season.

The OSU Hand Planter could help to decrease rising levels of food insecurity, ensure more sustainable agricultural practices, and provide for an escalating population. Food insecurity, described by Smith et al. (2000), can be caused by warfare, economic imbalances, poverty, environmental degradation, and population growth. In the realm of mounting issues with food insecurity, the OSU hand planter can be quite essential. With 95% of the world’s increasing population in the developing world, food production must increase by at least 70% (OSU Hand Planter for the Developing World, 2019). Producers in both developed and developing countries could utilize this device to make planting more feasible, less harmful, and increase agricultural sustainability for the future. In spite of the aforementioned benefits, a need exists to evaluate the yields emanating from the use of the hand planter.
