Effect of Direct Sowing, Transplanting, Priming and Boron Failor Application on Growth and Yield of Quinoa Genotypes
Research/Original Article (دارای رتبه معتبر)
In order to investigate the possibility of reducing the growth period and increasing the grain yield of different quinoa genotypes, in 2018, a factorial split plot experiment was conducted in a randomized complete block design with three replications in the research farm of Shahed University. The main factor included three different genotypes of quinoa (Titicaca, Giza 1 and Sajama) and the secondary factors included three models of planting methods (Transplanting, seed Priming with 1000 ppm Boric acid solution, and direct sowing) and boron foliar application at two levels (control and foliar application with 1000 ppm Boric acid solution). The results showed that the effect of genotype was significant on all studied traits. The highest plant height (123.38 cm) and grain yield (2860.228 kg/ha) were obtained in Giza 1 genotype. Also, the shortest period of growth and flowering was related to Titicaca genotype and the longest period was related to Sajama genotype. The effect of planting method on quinoa growth and yield traits was significant and transplanting was more effective than other methods. This method increased the plant height by 48.15% and grain yield by 176.69%, reduced the flowering (34.35%) and ripening period (37.97%). The priming was also able to improve the studied traits compared to the control. Of course, its effectiveness was not as high as transplanting. The effect of boron foliar application on grain yield was significant and increased this trait by 16.7%.
