Influence of different plant bio regulators and zinc levels on yield attributes and economics of fenugreek (trigonellafoenum graecum L.) under semi-arid conditions

The experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during rabi season to study influence of different plant growth regulators and zinc levels on growth and quality attributes of fenugreek (trigonellafoenum-graecumL.). The results revealed that foliar application of triacontanol and NAA significantly increased the yield attributes,viz.,pods per plant, seeds per pod, test weight and seed, straw and biological yield and gave significantly higher net returns and B:C (1.51 and 1.50)over control and thiourea applications. While, application of zinc in increasing levels upto 4 kg ha⁻¹ significantly increased the yield attributes and fetched significantly higher net returns and B:C (1.45) over 0 and 2 kg Zn ha⁻¹.The economic optimum dose of Zn as derived from response was found to be 5.326 kg Zn ha⁻¹.
