- Abstract
A study was conducted at Department of Agronomy, University of Agriculture, Faisalabad, during 2009-10 to work out the optimum sowing date and screening of most productive Chenopodium quinoa genotype at proposed sowing dates. Sowing dates were 15 December, 2009 (PD1) and 15 January, 2010 (PD2). Three exotic quinoa accessions (CPI-3, CPI-5 and CPI-7) were tested. Different phenological stages were considered for evaluation. Results indicated that significant effect of sowing dates, accessions and their interaction was observed but varied among different stages. It was noted that Quinoa sown on 15 January, 2010 (PD2) took more days to true leaf (17.22), four leaves stage (22.83), multiple leaves (26.67) and bud formation (43.78) than genotypes sown at PD1 (14, 19.44, 25.33 and 36.63, respectively). However, effects of accessions were non-significant at these stages. Contrarily, interaction was non-significant for days to panicle emergence and days to harvesting. Furthermore, effect of sowing dates, interaction of sowing date and accession on days to flowering was highly significant and showed that genotypes sown at PD1 took less days to flowering (46.56) than sown at PD2 (55.89). Highest grain and biological yield was obtained at PD1 (285.93 kg/ha and 6994 kg/ha) than PD2 (215.18 and 6519.8 kg/ha, respectively). Among sowing dates, it was affirmed that early sowing (PD1) performed better and exhibited better results than late sowing PD2. Regarding interaction between accessions and sowing dates CPI-5 gave good performance when sown on 15th December [CPI-5 x PD1 days to flowering (46), days to harvesting (116.7), biological yield (7673 kg/ha) and economical yield (327.0 kg/ha)].
