Studies on interaction effect of plant spacing on different varieties with respect to growth and yield of broccoli (Brassica oleracea var. italica. L)

Abstract

Present investigation was carried out during Rabi, 2015-16 at Horticulture Instructional Farm, CP College of Agriculture, SD Agricultural University, Sardarkrushinagar, Gujarat with 12 treatments replicated thrice in Split Plot Design. The treatment combinations were three plant spacings viz., S1: 30 cm × 30 cm, S2: 45 cm × 30 cm and S3: 45 cm × 45 cm with four varieties viz., Palam Samridhi (V1), Palam Vichitra (V2), Pusa Broccoli KTS-1 (V3) and Palam Haritika (V4). Results revealed that S1V3 recorded maximum plant height at transplanting (23.92 cm), while S1V2 recorded maximum plant height at 45 DAT (43.52 cm) while S1V4 recorded maximum at harvest (69.50 cm). Number of leaves at harvest (23.70), plant spread at 45DAT [E-W 55.09 cm N-S 53.27 cm] and at harvest [E-W 65.91 cm N-S 65.67 cm] were recorded maximum with treatment combination S3V4. The minimum number of days taken for head initiation and head harvesting were recorded with treatment combination S1V1 whereas maximum head diameter with highest yield per plant were observed with S3V2.
