Response of amara nth genotypes (.amaranth us tricolor l).) to stem production

Abstract

Abstract : An investigation was carried out to assess the stem production potential of eleven amaranth genotypes. The tallest plant height was recorded from the red force (95.65 cm) while the shortest in bone fire (46.08 cm). The genotype red force produced the minimum number of branches (1.60) and maximum in katua (11.45). The thickest stem diameter observed in aus danta (22.95 mm) and the thinnest from fire field (15.20 mm). The highest stem weight per plant obtained in aus danta (247.02 g) and closely followed by baromashy (217.48 g) and red force (206.07 g). The lowest leaf stem ratio were displayed in red force and aus danta (0.27) indicated that stem portion contributed more over leaf portion towards the yield. The genotype aus danta produced the highest stem yield (82.34 t /ha) per hectare, closely followed by baromashy (72.50 t /ha), red force (68.69 t /ha) and sureshsory (66.10 t /ha) and the lowest in fire field (28.23 t/ha). The genotypes baromashy (51.50 days) and aus danta (51 days) were the earliest while red force (113 days) and sureshsory (112 days) were the late to flower. Among the amaranth genotypes aus danta, baromashy, sureshsory and red force were found promising for stem production.
