Study the effect of different dates of transplanting and spacing on yield and quality of broccoli (Brassica oleracea var. italica) cv. Palam samriddhi in middle Gujarat condition

Abstract

The investigation entitled on “Study the effect of different dates of transplanting and spacing on yield and quality of broccoli (Brassica oleracee var. italica) cv. Palam samriddhi in middle Gujarat condition” was laid out and conducted at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat during Rabi season of the year 2018-19. The experiment consisted of nine treatment combinations comprising of three transplanting dates viz., 17th October (D1), 1st November (D2) and 16th November (D3) and three plant spacing viz., 60 x 30cm (S1), 60x45cm (S2) and 45 x 45cm (S3). The experiment was laid out in factorial randomized block design (FRBD) with three replications. Among all the different dates of transplanting, October 17th dates of transplanting Maximum stem diameter (40.50 cm) maximum curd weight (426.44 g), highest curd length (12.33 cm), highest curd diameter (140.44 cm), maximum curd volume (472.00 cm3 ), curd yield per plot (16.25 kg), curd yield per hectare (17.60 t), minimum days to harvest (55.91) whereas November 16th transplanting (D3) gave highest leaf length (37.84 cm) and least days to 50 % curd initiation (41.56) Among all the different spacing’s treatment S1 (60x 30 cm) gave maximum curd diameter (14.44 cm) curd volume (472 cm3) curd yield per plot (18.63 t) and curd yield per hectare (19.70 t). Among the interaction effect of different transplanting dates and spacing’s, yield attributes, highest curd diameter (14.66 cm) and curd volume (499.00 cm3) were recorded on November 1st transplanting with spacing of 60 x 30 cm (D2S1). Chlorophyll content had non significant effect among different dates of transplanting and spacing.
