Effects of Haulm Cutting Time on Haulm and Pod Yield of Peanut

Mehmet Arslan
A two-year study was conducted to determine the optimum haulm cutting time for maximum hay and pod yield in 2001 and 2002. The experimental design was a Randomized Complete Block in a split plot arrangement with three replications. Two peanut cultivars, NC 7 and Com and a peanut line, 75/1073, were employed as main plots. Four haulm cutting times with one week interval starting from 17 Weeks after Planting (WAP) were employed as split plots. Haulm fresh and dry weight significantly varied among cultivars and cutting times. The peanut line 75/1073 had the highest haulm fresh and dry weights in both 2001 and 2002. The highest haulm fresh and dry weights were obtained from the cutting performed at 20 WAP in both years. Crude protein content of peanut haulm linearly decreased from 10.6% at 17 WAP to 8.1% at 20 WAP. The two or more seeded pod weight, one seeded pod weight, shelling percentage, number of pods/plant and seed weight decreased with the early haulm cuttings in both years. The highest pod yield was obtained when haulm cutting was performed at the digging time. The result of the current study showed that the best haulm cutting time was 2 or 3 days before digging if the aim was to obtain the highest pod yield. However, the cutting time at 17 WAP provided the highest crude protein content.
