Abstract:
The field experiment took place during the Rabi season of 2022–2023 at the United University's Agronomy Research Farm in Jhalwa Prayagraj, Uttar Pradesh. “Influence of crop geometry and nitrogen levels on growth and yield of chia seed (Salvia hispanica L.)”. The experiment consisted of three, doses of nitrogen (80, 100, 120 kg/ha) and three spacing (40 × 15 cm, 50 × 15 cm, 60 × 15 cm). Three replications of the Randomised Block Design (RBD) statistical design were used to carry out the experiment. Variety used was “Chia Ampion W-83”. The results of the study show that, among the treatments, the use of 120 kg N/ha at 60 × 15 cm spacing produced significantly higher plant height (131.75 cm), number of leaves/Plant (275.86), fresh plant weight (961.23 g), dry weight (136.67 g/plant), root length (15.72 cm), number of branches (13.40), fresh root weight (9.25 g/plant), dry root weight (3.02 g), number of effective branch/plant (27.29), number of grains per spike (278.03), length of spike (18.75 cm), number of panicles (26.83) and test weight (2.03 g). Highest yield was found to be ttreatment combination receiving 120 kg N/ha at 60 × 15 cm spacing fetched highest grain yield (11.60 q/ha), stover yield (57.03 q/ha) and harvest index (28.20 %). The maximum economic gross return (177700 ₹/ha), net return (122843.28 ₹/ha) and benefit cost ratio (2.24) obtained with application of 120 kg N/ha at 60 × 15 cm brought about more return than control.
