Effects of tillage and planting methods on yield and yield components of sesame in Jiroft and Kahnouj region

To study the tillage and planting methods effects on yield and yield components of sesame, this experiment was conducted in an RCBD arrangement in a split plot with 3 replications in Jiroft region for 3 years. Main plots were: a) conventional tillage, b) minimum tillage, c) conservation tillage and d) no tillage. All plots were shallowly tilled with a harrow disk two days prior planting. Sub plots (planting methods) were: a) ridge planting, b) furrow planting c) flat planting. The effects of tillage methods on yield were significant at P=0.05, so that the lowest and highest yield were obtained in conventional tillage (1222.7 Kg/ha) and minimum tillage (1832.2 Kg/ha), respectively. Tillage methods had significant effect on pod number and the 1000 seeds weight in the first year and on the number of pods in second and so that the least in third year. The effect of different bed pattern on yield was also significant at P=0.05, so that the lowest yield (1306.7Kg/ha) was produced in the treatment “a” and the highest one (1780.9 Kg/ha) in the treatment “c”. The pod number per plant and height of the lowest pod from the ground were affected by bed pattern in the first year while in the second and third year only pod number was affected. Therefore the treatment “c” had the highest yield. Tillage methods and Planting patterns did not have any effect on traits such as stem diameter, plant height and reproductive stems numbers.
