Abstract :
In order to study the effects of planting date and plant density on morphological characteristics, quality as well as yield of strawberry, a split plot experiment was carried out based on randomized complete block design with three replications in Hashtgerd, Alborz Province, during 2013-2014. Main plots were three planting dates of February 20, March 11 and April 9 and sub-plots included three inter-row spacing of 20, 30 and 40 cm. The results indicated that planting date of March 11, as the best date, had the highest fruit yield by about 148.67 gr/plant which was above 30% increase of yield compared with April 9 . Moreover, the highest amount of vitamin C, anthocyanin, TSS, TA, TSS/TA and firmness were achieved in this time. As regards planting space, space increases from 20 to 40 cm increased yield by almost 25%. In general, the results showed that in Hashtgerd climate condition, the best planting date and space for strawberry, among experimented values, were March 11th and 40 cm respectively.
