Abstract

Background: Rice bean (Vigna umbellata L.) has recently been notified as a promising pulse crop. It is grown for green manure, green fodder and pulses. Potassium plays a major role in increasing the legume yield and yield components, besides provides tolerance to stress such as high-low temperature and drought. Similarly, iron is important for chlorophyll synthesis and is a key component of the nitrogenase enzyme, which is important for nitrogen fixation.
Methods: A field experiment was conducted during kharif season of 2020 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). India. Study the ‘‘Effect of potassium and iron levels on growth and yield of kharif Rice bean (Vigna umbellata L.)”. The present experiment was laid out in randomized block design (RBD).
Result: The results revealed that the application of 20 kg K2O/ha + 15 kg Fe/ha recorded maximum plant height (111.17 cm), branches per plant (23.40), nodules per plant at 60 DAS (35.67), plant dry weight (41.33 g/plant), pods per plant (26.20), seeds per pod (7.93), seed yield (1.67 t/ha), stover yield (3.95 t/ha), harvest index (29.69%), net return (Rs 81,155.6/ha) and B: C ratio (2.43). It can be concluded that 20 kg K2O /ha + 15 kg Fe/ha was found more productive as well as economic for Rice bean.
