Effect of P fertilization and growth regulators on yield, nutrient uptake and economics of fenugreek (Trigonella foenum-graecum L.).

摘要

A field experiment was conducted during winter season of 2005-06 and 2006-07 in Sekhampur, West Bengal, India, to study the response of fenugreek (T. foenum-graecum) to P levels (0, 13.1 and 26.2 kg/ha) and growth regulators (NAA at 20 ppm, triacontanol at 4 ppm, IBA at 40 ppm and control) on a laterite soil. Increasing levels of P increased significantly the yield attributes, yield and nutrient uptake of fenugreek. Foliar spray of NAA at 20 ppm proved significantly superior over the control, triacontanol and IBA in enhancing productivity. Net return and benefit:cost ratio was also highest with 26.2 kg P/ha and 20 ppm NAA.
