Studies on bed planting of summer moong for judicious use of phosphorus and irrigation water.

摘要

A field experiment comprising three levels of phosphorus (recommended P (40 kg/ha), 1.5-fold of the recommended P and 2-fold of the recommended P) and two methods of sowing (flat and bed planting) for summer moong cv. SML-32 was conducted during 2001 and 2002 at the Punjab Agricultural University, Ludhiana, Punjab, India. Irrigation treatments were 7.5 and 4.0 cm depth. Results revealed marked improvement in seed yield and water use efficiency under bed planting over those under flat planting, irrespective of level of phosphorus application. Bed planting system using 33.54 cm water against 51.41 cm used by flat planting system (34.7% saving) recorded 10.48 q/ha seed yield against 9.91 q/ha under flat planting. Bed planting exhibited better utilization of phosphorus in terms of significantly higher seed yield under recommended and double the recommended phosphorus level.
