Effect of travel speed and suction carried by a pneumatic planter on seed dosage and germination
Effect of travel speed and suction carried by a pneumatic planter on seed dosage and germination. The effect of the travel speed and suction carried by the John Deere 7300 pneumatic planterʼs vacuum pump on ICA-305 corn, FUNKʼS HW-1758 sorghum, and Soyica P-34 soybean seeds dosage, germination, and vigor was studied; five travel speeds were assessed (2, 4, 6, 8 and 10 km/h) and two vacuum pump work pressures (-1241.4 and -1738.0 Pa), at the sprocket combination 16/28. Seed weight (g) supplied and seed of variance distribution in two lineal meters, seed feasibility by germination and vigor tests, were determined. Analysis of variance for means of the variable and four regression models (linear, quadratic, cubic and quadruple) were applied. The linear regression model selected to explain correlation lead to conclude that travel speed of plant equipment do not affect seed dosage at two working pressures. No effect was found of planting work pressure on seed dosage. No effect was found of planting work pressure and travel speed on corn, sorghum, and soybean seed germination and germinated plantules vigor.
