<div style="text-align: justify;">The present study was aimed at optimizing operational and crop parameters influencing the mechanized harvesting and threshing of mung-bean crop with combine harvester. Two varieties of summer mung-bean SML-668 and SML-832 and one variety of kharif mung-bean ML-818 were selected for the study. Concave clearance was kept as 25 mm at front side and 10 mm from rear side. The height of cut the crop ranged from 8-9.5 cm. Threshing efficiency was more than 98% at cylinder peripheral speeds C3 and C4 in all varieties except SML-832. The percent grain damage was higher for higher cylinder peripheral speed and lower for higher forward speed. The grain damage ranged from 1.54 &ndash; 3.22 percent for C1, C2 and C3 cylinder peripheral speed in all crop varieties. Peripheral speed of 18.91 m/s and forward speed of 1.5 km/h was found to be optimum for harvesting mung-bean with combine harvester for all crop varieties.</div>

Optimization of operational parameters for mechanized harvesting of mung-bean (<em>Vignaradiata (L.) Wilczek</em>) with combine harvester

<div style="text-align: justify;">A field and laboratory experiment was conducted at Department of Seed Science and Technology, GKVK, UAS, Bangalore during 2014 to assess the response of fertilizer levels and spacing on seed quality parameters of green gram (Vigna radiata) cv. KKM-3. Experimental results revealed that fertilizer application of 50 :100 :100 NPK kg ha-1 + Green gram rhizobium (200gm) + PSB-Bacillus megaterium (200gm) recorded highest seed density (1.69g/cc), Test weight (46.2g), EC (0.750 dsm-1) TDH activity (0.999), germination percent age (97.25%), shoot length (21.98cm), rootlength (18.61cm), seedling dry weight (252g), seedlingvigour index I and II (3947 and 2450), protein percent (23.8%) and fieldemergence (90%) superior over other fertilizer treatments.Among the planting geometry 60&times;10cm recorded highest germination percentage (96.12%) as compared to 45&times;10cm (94.77%) and 30&times;10cm (93.82%). Interaction of fertilizerlevels and spacingthrough the application of &nbsp;50 :100 :100 NPK kg ha-1 + green gram rhizobium (200gm) + PSB-Bacillus megaterium (200gm) withplantinggeometry 60&times;10cm recorded higher seed quality parameters viz Test weight (48.3 g), protein per cent (24.5 %), germination percentage (98%), EC (0.73dsm-1), TDH activity (1.001), seedling dry weight (265 mg), shoot length (23.65 cm), root length (19.36 cm) and seedling vigour index I and &nbsp;II (4224 and 2603) and field emergence( 93%) were observed.</div>
