ABSTRACT

Background: Under current scenario of High cost of Production of Sugarcane crop, it is need of time to decide specific seed rate for individual varieties. Sugarcane seed contributes to 10-20% of cost of production and farmers invests about Rs. 20000/- per acre on planting material. The costs of seed can be curtailed by optimizing seed rate. Similarly, seed rate varies with different varieties. In this view, a field experiment was carried out to optimize the seed rate of promising sugarcane clones.
Methods: A field experiment was carried using randomized complete block design with factorial arrangements having three replications at Sugarcane Research Institute, Faisalabad during 2016-17 and 2017-18. 
Result: The results revealed that maximum cane diameter was recorded for S2008-AUS-133 at seed rate of 25000 and 50000 triple budded setts/ha. However; maximum number of canes/ha were recorded for S2008-AUS-133 at seed rate of 75000 setts/ha followed by HSF-240 at 75000 setts/ha. Maximum cane yield was noted for HSF-240 at seed rate of 75000 followed by S2008-AUS-133 at seed rate of 50000 and lowest can yield was recorded in S2003-US-127 at seed rate of 25000 triple budded setts/ha. Genotypic and phenotypic variances were higher for plant height (381.63, 133.91 cm) and cane yield (406.50, 330.65 kg/plot).Genotypic and phenotypic coefficient of variances were moderate for number of tillers (11.6%, 15.44%) and higher for cane yield (20.24%, 22.44%). It means that variability in 4 genotypes for cane yield was higher. Thus variety S2008-AUS-133 showed better performance at seed rate 75000 while during selection, number of tillers and height should be considered for further breeding program.
