Phosphorus-sulphur interaction in moongbean (Vigna radiata L. Wilczek): I. yield, phosphorus and sulphur contents Teotla U.S., Mehta V.S.*, Ghosh D., Srivastava P.C. Department of Soil Science, G.B. Pant Univ. of Agri. and Tech., Pantnagar-263145, India * Deptt. of Agric. Chern. and Soil Sci., R.B.S. College, Bichpuri, Agra - 283 105, India. Online published on 29 October, 2012. Abstract Effect of varying levels of both phosphorus (0, 30, 60, 120 kg P2O5 ha−1) and sulphur (0, 20, 40, 80 kg. SO4 ha−1) in combination was studied on yield and P and S contents of moongbean crop. Highest grain and straw yields were recorded in the treatment receiving 120 kg P2O5+ 80 kg SO4 ha−l. Simultaneous application of P and S also increased the contents of both the nutrients in grain as well as straw of moongbean. Effect of P x 5 interaction was significant. Balanced application of P and S is necessary for improving yield through better absorption and assimilation of both the nutrients. Top |
