Effect of gamma radiation treatment on growth and morphology of red Amaranthus

A field experiment was conducted during Rabi season 2020-21 at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) to study the effect of gamma radiation treatment on growth and morphology of red Amaranthus. The red Amaranthus was grown and treatments were replicated three times in randomized block design. The experiment consists of eleven doses of gamma radiation viz., 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050 GY and control. The result revealed that growth parameters viz., number of functional leaves plant -1 , Number of branches plant -1 , dry weight (g) plant -1 , Weight of inflorescence (g) plant -1 and Seed yield (g) plant -1 was recorded in 850 dose of gamma radiation which was at par to 1000 doses of gamma radiation. The lowest growth parameters were recorded under with out treated with gamma radiation (control).
