Abstract:
The study on “Evaluation of Amaranthus cultivars for anti-nutritional factors at different leaf clipping stages” was carried out at the experimental block of Department of Vegetable Science, College of Horticulture, Anantharajupeta, Railway Kodur, YSR Kadapa district, Andhra Pradesh during Spring-Summer season of 2021-22 with 15 amaranth cultivars collected from different regions. The experiment was laid out in a RBD with a factorial concept and comprised of 3 replications. The objective of this study was to determine the anti-nutrient content (oxalates, nitrates and tannins) of 15 amaranth cultivars at two clipping stages i.e., at 25 DAS (Vegetative stage) and at flower initiation stage. The results showed significant variation in anti-nutrient content in the fifteen amaranth cultivars due to both cultivars and clipping stages. Anti-nutritional analysis revealed that lowest oxalate (191.30 mg/100 g) and nitrate content (109.80 mg/100 g) was recorded in Arka Varna while Arka Arunima recorded lowest tannin content (92.35 mg/100 g). In conclusion, as the plants grow older, there was an increased accumulation of anti-nutrients.
