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

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.
