Growth and root yield of carrot as affected by magnetic water and sowing times

Abstract

This study examines effects of two sowing times (28/10 and 14/11 of 2014) and differentlevels of magnetic treatment of irrigation (0, 2500, 5000gauss) on productivity and yieldof carrot plants. A pot experiment was conducted at the Agriculture Research Center,Ministry of Agriculture in Kurdistan region-Iraq. This study was carried out during 28-10-2014 and 14-5-2015 the two factor experiment was laid out in complete randomizeddesign with four replicates, each replicate contain three plants. Data were collected fromall plants at harvest time and statistically analyzed. Comparisons between means weremade by using least significant differences test (LSD) at 5% probability. Magnetizedwater at the level of 2500gause caused the most significant effects on plant length(55.58cm), root length (30.19cm), (root diameter (35.14mm) and root dry weight(128.19gm). However, the sowing time 14/11 was more effective on plant length(54.64cm) and vegetative growth fresh weight (17.64gm). While the longest root obtainedwhen the seeds sown in 28/10. On the other hand the interaction of 2500gauss and4/11/2014 sowing time gave the maximum plant length, shoot fresh weight and rootdiameter (59.67cm, 20.63 gm and 43.75mm respectively), but the longest root and highestroot fresh weight were found in the interaction of the same level of magnetic water with28/10/2014 sowing time. The highest amount of the chlorophyll in the leaves (52.815%)was measured from the interaction of 2500gauss magnetic water and 14/11/2014 sowingtime, and the best carotene content in the roots (3.427mg/ml) was obtained from5000gauss magnetic water in the same sowing time.
