| Evaluating economic feasibility on three different tillage systems
Field research was conducted in Tifton, GA for comparing three tillage methods consisting of two strip tillage methods and a conventional tillage. Each system of tillage had three replications and Georgia Green was planted on twin row patter on dry land production system.
The lift in till and the conventional tillage methods produced significantly higher yields compared to strip till with wing. However, the higher fixed costs on conventional tillage significantly reduced the net returns to the land. The conventional tillage system produced more yields than the strip till with wing; however, the difference between the net returns for those two systems was only slightly less for the conventional tillage. The lift in till produced more yield than the conventional and the lower fixed and variable costs significantly increased the net returns to land.
The NRAVC indicates the amount of income that should cover all the fixed costs such as depreciation, general overhead, management and return to land. The NRAVC are positive for all three tillage methods and ranged from $211.66 per acre for lift in till to $109.96 per acre for strip till with wing. The results point out the maximum allowable fixed costs for the respective tillage system and it would assist growers in deciding whether investments on new equipment for a specific tillage system would be profitable.
Economic Evaluation of Growing Peanuts in Two Different Rotation Systems
The two different rotation systems being compared were Bahia, Peanut and Cotton, Wheat (cover crop), Peanut. The peanuts followed by bahia grass showed significantly lower TSWV and produced higher yields compared to the W-peanuts. The yield different was not significant.
The peanuts followed by cotton and wheat produced significantly better grade and produced higher net returns to land than the bahia- peanut rotation.
Using bahia as a rotation crop required additional herbicide application and this caused a reduction in net returns. The overall net returns for both rotations are negative.
Evaluation of Multiple Row Spacing Systems for Peanuts in Georgia:2001 Results
2001 yield and grade data for single, twin and triple row spacing systems was collected from five Georgia locations. Six different cultivars are included in the multiple row spacing data. All three different row spacings systems were employed in a 36 inches bed and the difference in machinery costs among the row patterns were eliminated by using a modified Burch Twin-row planter. Seeding rate per acre was adjusted to be the same. Additionally, production practices were identical.
There was no significant difference between the row patterns in any of the variables. The twin row patterns may give an average of 300 lbs. more yield and lower TSWV than those planted in single row pattern. The triple row pattern gave the lowest yield and the lowest net return.
None of the cultivar shows any statistically significant differences between the row patterns. Statistically significant differences are observed between the cultivars within the same row pattern.
