Abstract:The experiment entitled “Effect of sowing date and nitrogen on growth and yield of beet leaf (
Beta vulgaris var.
bengalensis)” was conducted during summer, 2020 at Vegetable Research Farm, RHRS, ASPEE College of Horticulture, Navsari Agricultural University, Navsari, Gujarat, India. The experiment was laid out in Split plot design with five replications. The experiment was arranged with three levels of sowing date (D
1:1
st Fortnight of January, D
2:2
nd Fortnight of January and D
3:1
st Fortnight of February) and four doses of nitrogen (N
1:0 kg N ha
-1, N
2:50 kg N ha
-1, N
3: 75 kg N ha
-1 and D
4: 100 N kg ha
-1). Plant height (7.40 cm and 37.14 cm, respectively) at 20 DAS and 40 DAS, number of leaves per plant (5.74 and 12.20, respectively) at 20 DAS and 40 DAS, leaf area (122.54 cm
2) and green leaf yield (8.47 kg plot
-1 and 14.70 t ha
-1) in plant from the 2
nd cutting were recorded higher in 1
st fortnight of January sowing (D
1).
Among the nitrogen doses, plant height at 20 and 40 DAS (8.69 cm and 40.12 cm, respectively), number of leaves per plant at 20 and 40 DAS (6.65 and 13.56), length of leaf (19.76 cm), leaf width (9.32 cm), length of petiole (7.89cm), leaf area (140.23 cm2), number of cuttings (3.73) and green leaf yield (10.25 kg plot-1 and 17.79 t ha-1 were obtained higher with application of nitrogen @ 100 kg ha-1 (N4).
Beet leaf sown at 1st fortnight of January with 100 kg N ha-1 (D1N4) had given the best performance in the yield parameter i.e. green leaf yield (10.66 kg plot-1 and 18.51 t ha-1). The higher net return of ₹ 1,27,671 ha-1 was obtained with D1N4 (1st fortnight of January and 100 kg N ha-1).
