Effect of Planting Date and Spacing on Growth and Yield of Fennel (Foeniculum vulgare Mill.) Under Irrigated Conditions

Abstract

Fennel (Foeniculum vulgare Mill.) plant is a medicinal aromatic herb and belongs to Apiaceae family. It has a rich nutritional value and has many medicinal usages. Very limited information is available in the literature about fennel cultivation and production practices. Therefore, this study was carried out to evaluate the effect of planting date and plant spacing and their interactive effects on yield, yield components and growth of Fennel under irrigation. Three planting dates (Oct. 1st, Nov. 1st and Dec. 1st) and four plant spacings (10, 20, 30 and 40 cm with constant row width, 60 cm) were used. Fruit yield was significantly (p<0.05) influenced by plant spacing and planting date and their interaction. Early planting significantly increased the fruit yield combined with higher number of branches per plant, number of umbrella per plant, number of fruit per plant and plant height. The percentage of increases in Oct. 1st were 34.4 and 32.2% in fruit and biological yield respectively compared with Dec. 1st. Harvest index and thousand fruit weight was not significantly affected by planting date. Increase plant spacing to 30 cm led to more than 15% increase in fruit and biological yield. The early planting date with 30 cm plant spacing resulted in higher fruit (4136 kg ha(-1)) and biological yield (10,114 kg ha(-1)).

Effect of Seed Sowing Time and Nutrients on the Growth and Yield of Fennel (Foeniculum vulgare)

“…This might be due to the fact that last week of November possibly received favorable condition for the quickest growth than those of other sowing time. This result agrees with the result obtained by [14] they reported that the sowing of fennel in the first date (20 th November) resulted in increase of all studied vegetative [15]. The plant height was observed significantly influenced by different nutrient application (Fig.…”

Impact of Planting Dates and Organic Fertilization on Growth, Productivity and Essential Oil Components of Coriander (Corianderum sativum L) Plant.

“…Whereas the low yield at the late sowing date was caused by the plant quickly entering the reproductive stage, which left inadequate time for vegetative growth (Sharangi, 2014, Rahnavard et al, 2010 In addition to, early seeding of black cumin plants revealed an increase in plant height and an increase in the number of main and secondary branches each plant (Al-Zubaidy et al, 2020) additionally, the early cultivation of fennel resulted in a considerable increase in plant height, beside an increase in the number of branches and fruits each plant (Al-Dalain et al, 2012).…”

Application of SCoT Marker to Discriminate Genotypes and Synthetic Cultivars of Fennel (Foeniculum Vulgare Mill.)

“…According to the World Health Organization, medical plants are responsible for the health of more than 80% of the world's population in developing nations, while the usage of chemical compounds derived from medicinal plants is expanding in industrialized countries (Canter et al, 2005). Fennel is a herbal, perennial, fragrant plant with hermaphrodite owers and open pollination that is native to the Mediterranean region (Al-Dalam et al, 2012). The seed of the fennel plant is the commercial portion, which is used either directly or to extract essential oils.…”
