Productivity of Fenugreek Varieties (<i>Trigonella foenum-graecum</i> L.) in the Coastal Saline Areas of Noakhali

Abstract

The experiment was conducted at the farmer`s field of Boyerchor, Hatia, Noakhali under On-Farm Research Division, Bangladesh Agricultural Research Institute (BARI), during the rabi seasons of 2011-2013 to study the effect of variety on the productivity of fenugreek in coastal saline soil. The experimental treatments included 3 varieties viz. V₁= BARI Methi 1, V₂ = BARI Methi 2, V₃ = Local Methi. The experiment was laid out in a randomized complete block design with six dispersed replications. There was a strong varietal influence on crop growth and seed yield. Among the varieties, BARI Methi 2 showed the best results in terms of plant height, number of branches, number of pods and number of seeds pod^-1 resulting in the highest seed yield of 1497 kg ha^-1. It was also observed that plant mortality of fenugreek was highly affected at germination stage when the soil salinity was above 4 dSm^-1. However, at the later stages of crop growth up to the maturity, the salt tolerance of the crop was higher varying from 4-12 dSm^-1. It was indicated that critical range of salinity level for cultivation of fenugreek was 3.42-12.2 dSm^-1 from germination till to maturity. Among the fenugreek varieties, BARI Methi 2 offered the highest net return of Tk. 50150 coupled with a benefit cost ratio of 3.03. Though total cost was the same, BARI Methi 2 showed higher BCR (3.03) over BARI Methi 1 and local Methi due to yield differences.
