Amaranth is a quick growing multipurpose crop suitable for poor soils of semi-arid and seasonal wet areas. This crop is highly resistant to extreme stress conditions. Grain amaranth (Amaranthus hypochondriacus L.) is a potential upcoming subsidiary food crop, considered by many as crop of the future. Green leaf of amaranth is used as vegetable for human being and fodder for animals. The grains of this crop are used in quality human diet. Protein content in grains varies from 11-13 % and the quality of protein is equivalent to fish protein. It is observed that seeds of A. cruentus L. A. hypochondriacus L. contained higher crude protein (16.86 %), moisture (11.88 %), crude fat (4.30 %), crude fibre (2.90 %), ash (2.10 %), carbohydrates (63.13 %), calcium (169.63 mg/100 g), iron (10.42 mg/100 g), phosphorus (395.33 mg/100 g) (Munjal et al., 1999). Medicinal point of view the amaranth is also important. The tocopherol fraction of amaranth oil contains important cholesterol lowering agents, some International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 07 (2019) Journal homepage: http://www.ijcmas.com Field experiment was conducted on dark brown soil of the college farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari during rabi season of 2016-2017 to study the effect of integrated weed management on growth, yield, yield attributes and economics of grain amaranth (Amaranthus hypochondriacus L.) Production potential, higher profit and effective weed control in grain amaranth can be achieved by maintaining weed free through hand weeding throughout crop growth period, where labours are easily available. In case of labours scarcity, application of oxyfluorfen 50g/ha PE fb fenoxy prop ethyl 50g/ha PoE at 40 DAS also equally effective.
