Abstract:
The present trial was performed to study the effect of nitrogen and spacing on growth parameters of vegetable amaranth (Amaranthus spp. L.) at Govind Ballabh Pant university of Agriculture and Technology during summer season of 2021-22. The experiment was set out in factorial randomized block design along with three replications. The experiment comprised of four variable nitrogen levels which includes N1 (N@ 0 Kg/ha), N2 (N @30Kg/ha), N3 (N@60Kg/ha) and N4 (N@90Kg/ha) along with three spacing viz., S1 (45 cm×15cm), S2 (45 cm×30 cm) and S3 (45 cm × 45cm). Data on growth parameters were collected and analysed using analysis of variance (ANOVA). Results indicated significant increase in plant height and number of branches per plant was observed with the increased levels of applied nitrogen. However, the plant height was significantly higher in closer spacing. Among the variable nitrogen levels, maximum plant height was recorded in N4 (N@90kg/ha) and with respect to spacing it was recorded maximum in S1. Among the interactions, N4S1 (N@ 90kg/ha + 45×15 cm) found best for plant height. On the hand, N4S3 (N@ 90kg/ha + 45×15 cm) found superior in terms of number of branches per plant.
