Effect of different spacing on varieties of Brinjal (Solanum melongena L.)

Abstract

The present investigation entitled “Effect of different spacing on varieties of brinjal (Solanum melongena L.)’’ was carried out during Late Kharif season of 2020-21 at College Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat. There were four levels of spacing 90 cm × 90 cm, 90 cm × 60 cm, 60 cm × 60 cm, 45 cm × 45 cm and three levels of variety viz., GJB 3, GRB 5 and Doli 5. The experiment was laid out in Split Plot Design with three replications. Among four spacing, 45 cm × 45 cm performed significantly superior over other spacings with respect to maximum plant height at 60 DAT (30.02 cm), at last harvest (55.64 cm), minimum days taken to first picking after transplanting (97.56), maximum number of fruits per plant (28.24), fruit yield per plot (32.85 kg) and fruit yield per ha (20.28 tones). In case of varieties, GRB 5 was found significantly superior with respect to maximum plant height at 60 DAT (28.88 cm) and at last harvest (61.28 cm), plant spread at 90 DAT (E-W) (49.86 cm) and (N-S) (49.75 cm), minimum days to flower initiation (79.75) and days taken to first picking after transplanting (101.83), maximum number of pickings (11.00), fruit yield per plant (1.24 kg), fruit yield per plot (22.49 kg), fruit yield per ha (13.88 tones) and total soluble solids (7.92 ˚Brix). The highest B: C ratio (1:2.52) was recorded under s4v2 (45 cm × 45 cm and GRB 5) rest of treatment.
