Effect of Zinc, Boron and Molybdenum on the seed yield of carrot (Daucus carota L.)

Abstract

An experiment was conducted at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during October 2006 to May 2007 to evaluate the effects of zinc, boron, and molybdenum on the seed yield of carrot. The soil of the studied field was deficient in zinc, boron, and molybdenum and represents Salna Series of Shallow Red Brown Terrace under Madhupur Tract (AEZ-28). Four (4) levels each of zinc (0, 2.0, 4.0, and 6.0 kg/ha), boron (0, 1.0, 2.0, and 3.0 kg/ha) and molybdenum (0, 0.5, 1.0, and 1.5 kg/ha) were used to formulate 11 treatment combinations to observe their effects on the seed yield of carrot (cv. Bejo Shetal). A blanked dose of N120P54K150S20 kg/ha was also applied to nourish the crop. The experiment was laid out in a randomized complete block design with three replications. The seed yield of carrot was significantly increased due to integrated effects of zinc, boron and molybdenum. The highest seed yield (362.28 kg/ha) was found with Zn4.0B2.0Mo1.0 kg/ha combination, which was 283% higher over control. The maximum germination percentage (91.30) and vigor index (4.99) of seed was also recorded from the same treatment package and thus may be recommended for the production of carrot seed in the studied or alike area of the country.

Response of Inorganic Fertilizer and Plant Growth Regulators on Growth and Seed Yield of Radish (Raphanus sativus L.)

“…The maximum seed yield (14.01q/ha) was associated with foliar application of GA3 @150 ppm (P3) which proved its superiority over other concentrations of GA3 and NAA. Similar results were recorded by Malek et al [10] in carrot, Panwar et al [11], Mohanta et al [24]. The highest seed yield (q/ha) was recorded at F2 (N60 : P40 : K50) and found significantly superior to the rest of the levels.…”

Effect of Variety, Fertilizer Combinations, and Harvest Age on Biochemical Qualities of Carrot (Daucus carota L.) in a Tropical Environment

“…In this study, harvesting at different ages yielded distinct variations in the biochemical composition of carrot roots. The observed variability in the biochemical constituents of carrot roots as a function of harvest age corroborates earlier reports that the nutritional quality of carrot roots varies with harvest age 33,34 . The corresponding increase in fiber content with an increase in harvest age is consistent with the findings of Paltrinieri 35 who observed that produce harvested too late accumulates excessive fiber.…”

Evaluating the Response of Carrot (Daucus carota L.) to Different Macronutrients and Harvesting Time

“…Secondly, variations in soil nutrient levels and deficiencies can hinder nutrient uptake by carrot plants, affecting their overall health and productivity [6]. Thirdly, improper timing of harvesting can result in reduced quality and market value due to issues such as lignification, excessive root branching, or loss of moisture content [7]. Fourthly, nutrient imbalances or deficiencies can predispose carrots to diseases and pests, further compromising yield and quality.…”

“…The harvesting period has a significant impact on carrot yield. The most crucial elements influencing carrot storage are temperature and root yield, which are determined by harvesting time [15]. Fritz and Habben [16] suggested that carrot should be harvested at proper stage of maturity; otherwise, it will become fluffy and unfit for consumption.…”
