Grain, forage and yield components of mung bean as affected by phosphorus and plant population

Eltohami EL Tayeb ¹, Mohamed A M.Khair² and Mozzamil A.M Eltalib

Abstract:

Exception to few irrigated crops, the majority of sorghum and millet in Sudan are rain - grown. The continuous cropping coupled with the unlikelihood of the application of nitrogenous fertilizers and the low and erratic rain fall, have resulted in extremely low grain yields. Of these crops a possible way to improve yields in those areas could be through the adoption of a farming system which includes a quick maturing legume with high N-fixation ability. Mung bean, ( Vigna radiata L.) is a possible crop which could be used. An experiment was conducted in the Gezira Research Station for two seasons (winter 1998/1999 and summer 1999) to provide information on the crop .The treatments comprised two phosphorus (P) levels (O and 92 Kg P₂O₅ as triple superphosphate) and three plant populations ( 16, 32 and 48 plants/ m²). Observations included plant height (PH),leaf area index (LAI), total dry matter (TDM), number of pods per plant (PPP) and grain yield only (GY).
The results of the summer experiment revealed significant increases in PH, LAI, TDM, PPP and GY due to high P level. Plant populations, on the other hand, have significantly increased LAI, TDM in both seasons and GY in the summer
