Abstract
The present experiment entitled âEffect of Various Sources of Nitrogen on Growth, Yield, and Quality in Vegetable Amaranthus (Amaranthus tricolor L.)âwas conducted during two consecutive summers of 2020 and 2021 at Horticulture Research Farm, Department of Horticulture and Post-Harvest Technology, Palli Siksha Bhavana, Visva Bharati Sriniketan, West Bengal. The trial was laid down in randomized complete block design (RCBD) with four replications and five treatments viz. T1: 100% N Inorganic + 0% N FYM + 0% N VC, T2: 75% N Inorganic + 12.5 % N FYM + 12.5% N VC, T3:50% N Inorganic + 25% N FYM + 25% N VC, T4: 25% N Inorganic + 37.5% N FYM + 37.5% N VC, T5: 0% N Inorganic + 50% N FYM + 50% N VC. Based on the pooled data, results of study revealed that maximum plant height (54.6 cm), number of leaves (16.3), leaf length (17.8 cm), leaf width (7.6 cm), leaf area index (8.7), petiole length (7.3 cm), stem diameter (1.4cm), plant weight (53.9g), yield per plot (7.4kg), yield per hectare (213.3 q), chlorophyll a (40.7 mg/100 g), chlorophyll b (21.5 mg /100g), total chlorophyll (62.2 mg/100g), ascorbic acid (331.9 mcg/ 100g), Protein (5.2%), and B: C Ratio (1.55) were found with the application T4: 25% N Inorganic + 37.5% N FYM + 37.5% N VC. It was evident that inorganic nitrogen replacement with organic nitrogen from 25 to 75% is possible in vegetable amaranth without affecting yield.
