Abstract:
A field experiment was conducted during rabi season 2019-20 at Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan) to evaluate the effect of phosphorous and iron on yield attributes, yield and economics of the fenugreek crop. Treatments comprises of four levels of phosphorus viz., control, 20 kg, 40 kg and 60 kg P₂O₅ ha^-1 and four levels of iron viz., control, 5 kg, 7.5 kg and 10 kg FeSO₄ ha^-1 and examined in factorial randomized block design (factorial RBD) with three replications taking fenugreek variety “PRM 45” as test crop. The results revealed that various levels of phosphorus showed significant effect on the plant height, test weight and yield (seed, haulm and biological) and harvest index of fenugreek crop. The maximum plant height (93.49 cm) at harvest was recorded with the application of 60 kg P₂O₅ ha^-1, which was statistically at par with the plant height under application of 40 kg P₂O₅ ha^-1. Application of increasing levels of P₂O₅ @ 60 kg P₂O₅ ha^-1 has increased the test weight (12.07 g), seed pod^-1 (17.64) seed yield (2061 kg ha^-1), haulm yield (6980 kg ha^-1) and biological yield (9040 kg ha^-1) of fenugreek crop, which were significantly at par with those recorded under application of 40 kg P₂O₅ ha^-1. The application of increasing levels of iron also has significant improvement in plant height (90.93 cm) and yield attributing characters test weight (11.89 g), number of seeds pod^-1 (17.23), seed, haulm and biological yield were (1957), (6650) and (8607) kg ha^-1 respectively, with the application of 10 kg FeSO₄ ha^-1, which were found at par with 7.5 kg of FeSO₄ ha^-1.
