Assessment of Grain yield Potential in Urdbean (Phaseolus mungo)

Experiments were conducted at Pulses Research Sub-Station, Samba, J & K State during 2001–04 to identity high yielding biotic stress resistant variety of urdbean responsive to the various production factors, under rainfed conditions. Selection, SUS-1 proved superior to the three check varieties used with respect to yield, days to maturity as well as reaction to yellow mosaic virus and cercospora leaf spot. The ‘on-farm trials’ conducted during 2003 and 2004 also showed superiority of SUS-1 over the local check variety. Further, the entry gave better response to the various production factors viz., fertilizer application, weed control and plant protection measures in comparison to the check variety. Pant U-19. The seed yield was highest (1251.9 kg ha¹) in the treatment where all the production factors were clubbed. Per cent defoliation by general defoliators, whiteflies number as well as per cent yellow mosaic infected plants, all showed a significant decrease with improved variety or application of plant protection measures.
