Effect of time and frequency of jerking on growth and yield of carrot (Daucus carota L.) cv. Super Lal

Abstract

The field experiment was carried out during the year 2010- 2011 to standardize the time and frequency of jerking of carrot cv. Super Lal. The soil of the experimental field was loamy clay in texture having pH 8.3, EC 0.314 dS/m, organic carbon 0.28 %, available nitrogen 176.2 kg/ha, available P2O5 28.2 kg/ha and available K2O 187.4 kg/ha. The characteristics of Baran district soil at different depth level are given in (table-1). Jerking of carrot plants in east to west direction was done on 10,20,30,40 and 50 days after sowing and its suitable treatment combination with the help of jute thread soon after irrigation. The control plot was left free without any jerking. These treatments were laid out in randomized block design with three replications. Carrot seeds are sown in flat beds at row to row spacing of 20cm followed by light irrigation. The length and diameter of roots was counted after digging of carrot. The degree of bending the plant was measured with the help of protractor after every jerking of carrot plant. After maturity of the crop, carrot taproots were digged out and yield data were recorded for statistical interpretation.
