Abstract:
An experiment was conducted to assess the effect of planting date and variety on growth and yield of potato at Anderacha district, Western Zone of SNNPRS, from October 2011 to March 2012. Five planting times (October 20, October 30, November 9, November 19 and November 29) and three varieties (Jallene, Guidene and local) were combined in 3x5 factorial arrangement and laid out in randomized complete block design with three replicates. Data were collected on growth and yield parameters and analyzed using SAS Version 9.2 statistical software. The result showed that early planting (October 20) delayed emergence and flowering by about 4 and 15 days, respectively and increased plant height by 10.68cm than the latest planting on November 29. The number of stems per plant increased with delayed plantings however tuber number decreased in late plantings. Early planting produced significantly heaviertuber weight (83.80g) which progressively reduced in subsequent plantings, whereasdelay in planting resulted in higher unmarketable yield. Guidene took significantly longer days to emerge and flower (19.2 and 65.6 days, respectively) and plants were significantly taller (77.77cm) than Jalene and local variety. Jalene produced significantly (P
