Abstract:
A field experiment was conducted at Agronomy Instructional Farm, C.P. College of Agriculture, S.D. Agricultural University, Sardarkrushinagar, Gujarat to find out the Effect of time of sowing and spacing on grain amaranthus during rabi season of the year 2021-22. The experiment consists of twelve treatment combinations comprised of four time of sowing (3^rd week of October, 1^st week of November, 3^rd week of November and 1^st week of December) and three row spacing (22.5 cm, 30.0 cm and 45.0 cm). Among four time of sowing 3^rd week of November to 1^st week of December was found markedly superior than 3^rd week of October and 1^st week of November in respect to growth and yield attributes viz., Plant height, Inflorescence length, Grain yield per plant, Test weight, Grain yield and Stover yield, Harvest index along with Benefit Cost ratio Whereas, 22.5 cm row spacing recorded significantly highest Grain yield and Benefit Cost ratio followed by 30.0 cm row spacing and lowest was associated with 45.0 cm row spacing, but reverse trend was observed regarding length of Inflorescence and grain yield per plant both. The highest net realization of ₹ 100443 ha^-1 and higher BCR value of 3.34 were recorded in time of sowing 3^rd week of November. Among spacing S₁ (22.5 cm) resulted in highest net realization ₹ 104671 ha^-1 with BCR value of 3.36.
