Mung bean is one of tropical and semitropical pulses that is important in food, fodder, green manure and improves soil fertility and is a cheap source of protein in human direct consumption. The use of zeolite in soils with heavy texture, because it keeps moisture and nutrients around the seeds and roots is very important. On the other hand, the application of techniques of improving seed quality such as priming, improves seed germination in condition of nutrients limitation. This experiment was conducted as a factorial in Randomized Completely Block Design (RCBD) with three replications in the farm of the Ramin University in August 2011. Experimental factors included Culture System Optimization (CSO) in six levels Zeolite application+ seed priming (O1), Zeolite application (O2), seed pelleting+ seed priming (O3), seed pelleting (O4), seed priming (O5) and control (O6) with three mung bean cultivars included Hendi (C1), NM-54 (C2) and VC11-18b (C3). The results showed that cultivar was a significant effect on all of the traits however the effects of CSO on spad index, nitrogen harvest index (NHI), rate of biological yield accumulation and grain yield production rate weren’t significant. Hendi cultivar showed the highest grain filling rate. Combination of Hendi seed pelleting with zeolite and zeolite application and Hendi cultivar were obtained highest of grain yield, grain protein content and harvest index. Priming of Hendi seeds produced the highest biological yield and showed that the reactivity of Hendi cultivar in usage agronomic factors was higher than other cultivars and was promising for green manure planting.

Keywords: grain yield production, grain protein content, green manure, grain filling rate
