Effect of phosphorus and farmyard manure on yield, yield attributes and nitrogen, phosphorus and potassium uptake of fenugreek (Trigonella foenum-graecum)

A field experiment was conducted during the winter (rabi) season of 1996–97 and 1997–98 at CCS Haryana Agricultural University, Hisar, to study the effect of farmyard manure (0, 5, 10 and 15 tonnes/ha) and phosphorus (0, 20, 40 and 60 kg/ha) on 2 fenugreek (Trigonella foenum-graecum L.) genotypes (‘HM 65 and ‘NLM’). Genotype ‘NLM’ was significantly superior to ‘HM 65’ in terms of more number of branches/plant, pods/plant and seeds/pod. These yield attributes resulted in higher seed and straw yields of ‘NLM’. However, non-significant differences were observed for nutrient uptake between both the genotypes. Each successive dose of FYM up to 15 tonnes/ha significantly increased the number of branches, pods/plant, seeds/pod, seed straw, and biological yields and nutrient uptake over their lower doses. Increasing levels of phosphorus up to 40 kg P₂O₅/ha significantly increased the yield-attributing characters, seed yield and quality parameters of fenugreek.
