Planting Beans (Phaseolus vulgaris), relay, September, 2014
The idea was to see how the GS could work planting beans. Because our system is maize- bean and a farmer is going to love the GS, if is useful for both crops. To my surprise the GS work well and easily releases 2 beans per hit. In El Salvador they plant 2 or 3 plants per hit. Farmers around me, found the planter as a nice idea, because it could save seed when planting s, remember this seed is more expensive, nowadays cost around $1.30 per pound, and when they hire people for planting, if they are in a hurry they put until 5 seeds per hole, increasing the amount of seed to use per area.
