Effect of different date of sowing on growth, yield and quality of carrot (<em>Daucus carota</em> L.)

Abstract

The present investigation, effect of different date of sowing on growth, yield and quality of carrot (Daucus carota L.) was carried out at Horticulture farm, College of Horticulture, S. D. Agricultural University, Jagudan Gujarat during rabi season 2017-18, comprising three dates of sowing 1st October (d1), 15th October (d2) and 1st November (d3) was statistically analyzed with randomized block design for growth, yield and quality parameters of carrot and are summarized below. The date of sowing 15th October (d2) significantly increased plant height (16.49, 40.28 and 68.64 cm) and number of leaves (3.74, 8.82 and 10.60) at 30, 60 DAS and at harvesting time respectively, weight of root (72.10 g), root yield per plot (6.44 kg), root yield per ha (20.44 t), productivity per day (247.70 kg), root length (22.31 cm), collar diameter (37.62 mm), volume of root (75.32 cc), total soluble solid (8.00°B), reducing, non-reducing and total sugar (4.40, 3.50 and 7.90%, respectively). All parameters showed a decreasing trend as sowing date was delayed.
