Abstract:
In this study the effects of six different harvesting method condition and harvesting method. Field tests for detecting field drying rate done in randomized complete block design with six treatments in four replications and three cut. The harvesting methods including harvesting with mower as control, harvesting with mower and displacement of rows per day, harvesting with mower and rack at the end of first day, harvesting with swather, harvesting with mower and chemical treatment with potassium carbonate and harvesting with swather and chemical treatment (potassium carbonate). Initial moisture content of crop was determined with standard method. The moisture content of samples were determined in first, second and third day in 2, 3 and 4 h intervals. According to the results the highest drying rate was pertained to harvesting with swather and chemical treatment. The values for drying constant of this treatment were obtained in cut 1 to 3 equal to 0.057, 0.06 and 0.051, respectively. The forage loss in another field tests in randomized complete block design with six treatments and four replications was carried out. Harvesting with mower and rake at the end of first day had maximum value of loss with 4.6% and 3.7%, respectively.
