Peanuts Paclobutrazol

Peanuts Paclobutrazol is a semi determinate crop has vegetative growth continuously even if reach the flowering stage. In order to maximize assimilate for filling the pod, it is necessary to investigate source size modification and sink source balance in peanut. Therefore, retardant as a growth regulator can be used for regulating plant growth balance.
Moreover,foliar application of paclobutrazol at 100 and 200 ppm in the stage of initial pod formation and initial and medium pod filling increased seed production of peanuts.This research aims were to investigate the effect of time application of paclobutrazol on the growth of peanuts; to optimize the paclobutrazol concentration to growth and production of peanuts; and to investigate the growth pattern and production of peanuts
The research was conducted to investigate the effectiveness of paclobutrazol on the growth and production of Peanuts. Planting was conducted in April to July, using 2 peanut Varieties. Design of experiment was split plot. Paclobutrazol was applied at 6 and 8 Weeks after Planting,
Observation covered growth and production, such as dry matter production, leaf area index, pod number, pod weight, non structural carbohydrate and total nitrogen in the stem. The results showed that paclobutrazol concentration at 200 ppm increased pod weight and productivity of peanuts, however, did not affect the total soluble carbohydrate and nitrogen content in the stem.Peanuts showing bigger leaf area and higher chlorophy
