Abstract

Grain Amaranth (Amaranthus hypochondriacus L.), a quick growing and upcoming subsidiary food crop of the future, belonging to the family Amaranthaceae and genus Amaranthus. Although, general package of practices for Grain Amaranth is available at all India level, there are limited studies on Integrated Nutrient Management. Hence, the field experiment was carried out to investigate the impact of integrated nutrient management on grain amaranth (Amaranthus hypochondriacus L) yield and economics at the field unit AICRP on Potential Crops, MRS, Hebbal, UAS, GKVK, Bengaluru during late kharif-2017. Twelve treatments were replicated three times in the RCBD design of the experiment. Bio-fertilizers and various combinations of organic and inorganic nutrition sources are used in treatments. The maximum net return per hectare was Rs. 47851 when 100% RDF and bio-fertilizers were applied. This resulted in significantly higher grain production (1681 kg ha-1) and yield component, including panicle length (48.50 cm), panicle weight (53.73 g), and yield per plant (27.70 g plant-1). Application of 100% N equivalent through vermicompost + bio-fertilizers resulted in a lower net return of Rs. 170.

Conclusion

Higher yield, yield traits, and economics in the production of grain amaranth can be attained under integrated nutrient management practice. On the basis of results obtained under present investigation and possible reasons for their jaggedness having discussed, the following conclusions were drawn. Application of 100 % recommended dose of fertilizer along with bio-fertilizers are needed for optimization of higher grain yield (1681 kg ha-1) and yield component viz. panicle length (48.50 cm), panicle weight (53.73 g) and yield per plant (27.70 g plant-1), maximum net return of Rs. 47851 per ha.
