Effect of Different Levels of Nitrogen and Sulphur on Yield and Nutrient Uptake by Fennel (Foeniculum vulgare Mill.)

Abstract

An experiment comprising of four levels of nitrogen viz., 0, 60, 90 and 120 kg ha-1 and three levels of sulphur viz., 0, 20 and 40 kg ha-1 was conducted infactorial randomized block design, replicated thrice during rabi 2016-17 at the Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh to study the influence of N and S on yield and uptake of nutrients by fennel. The experimental medium deep black soil was clay in texture and had pH 8.06 and EC 0.41 dSm-1. Application of nitrogen @ 120 kg ha-1 and 40 kg S ha-1 individually had significant effect on yield and uptake of N, P, K, S, Fe, Mn, Zn and Cu by seed and stover. Application of 90 kg N ha-1 with 40 kg S ha-1 produced significantly higher seed and stover yield than the other treatments.

Influence of Different Nitrogen Levels and Spacing on Seed Yield and Economics of Fennel (Foeniculum Vulgare Mill.)

“…It also proved the finding of Azizi et al and Nath et al [11 and 12] in Ajowain and Tehlan et al [13] in coriander.At the same time, Kucha et al [14] observed a significant maximum number of umbels per plant in fennel on applying 120 kg [15 and 16] observed an increase in the number of umbellets per umbel with an increased nitrogen dose of up to 120 kg N ha -1 in fennel crop. It might be due to the greater availability of photosynthates, metabolites, and nutrients for the development of reproductive structures as nitrogen played an essential role in chlorophyll synthesis, which is the main absorber of light energy needed for photosynthesis and thus, increased photosynthates production and translocation in the plant.…”
