Effect of Nitrogen on the Growth and Yield of Carrot (Daucus carota L.)

Abstract

An experiment was carried out at farmer's field in Debigonj, Panchagorh during November 2009 to February 2010 to evaluate the effect of four levels of applied nitrogen on the growth and yield of carrot. The experiment was laid out in a Randomized Complete Block Design with three replications. The maximum plant height (47.36 cm), root length (16.17 cm), fresh weight of leaves (145.1 g), dry matter content (11.66 g) of leaves, fresh weight of root (68.33 g), dry matter content of root (15.90%), gross yield (22.55 t/ha) and marketable yield (20.67 t/ha) were found in 100 kg N/ha.

“…The maximum root yield (13.46 ± 0.64 t/ha) was obtained from X2 while the minimum (1.17 ± 0.23 t/ha) was obtained from control. Our results obtained on root yield are in conformity with data found in literature: [34]; [13] and [11] also reported similar results in carrot. In this study, root yield (1.17 ± 0.23 t/ha) of carrot from control is lower than those found in literature.…”

“…In fact, these authors had observed that the length of carrot root varies from 15.77 to 19.50 cm. In addition, studies of [13] reported that the length of carrot roots varies from 15.39 to 17.19 cm. There was a positive and significant correlation (r = 0.64; p <0.05) between the length and diameter of carrot roots obtained in this study.…”

“…These results are different to those obtained in the literature. Indeed, [13]evaluated the effect of nitrogen on the growth and yield of carrot in Debigonj, Panchagorh and found that the weight of fresh roots vary from 38.33 g for control to 68.33 g in 100 Kg N/ha. This would be explained by different climaticand edaphic conditions in the studies areas.…”

“…This would be explained by different climaticand edaphic conditions in the studies areas. Present study was carried out underSudano-Guinean climate, on argillaceous soil, while trial of [13] took place under sub-tropical climate on sandy soil. This corroborates the studies of [32] and [33].In fact, these authors reported that plants productivity varies according to genotype and agroecological zone.…”

“…In this respect, [11] study the influence of chicken manure and NPK (17-17-17) fertilizer on growth and yield of carrot in Rwanda and reported that combination of chicken manure and NPK had shown significant influence on the growth and yield of carrot.Studies of [12] on response of farmyard manure and inorganic fertilizers for sustainable growth of carrot in Northern Nigeria show that the application of nitrogen, phosphorous and farmyard manure significantly increased agronomic parameters. [13]evaluate the effect of four levels of applied nitrogen on the growth and yield of carrot in Debigonj, Panchagorh and found that maximum agronomic parameters were found in 100 kg N/ha.…”
