Abstract: There is a need of hour to study the effect of organics on physiology and yield components of various crops to boost up the productivity. Therefore, this investigation was undertaken to find out the suitable organics for increasing the production potential in cluster bean. A field experiment was conducted at the Main Research Station, College of Agriculture, University of Agricultural Sciences, Dharwad during kharif 2009-10 to study the influence of organics on growth, development and various growth parameters of cluster bean genotypes. The investigation was carried out in three genotypes namely Local, an improved variety (Pusa Navbahar) and an hybrid (SARPAN-101). The result revealed that genotype SARPAN-101 (hybrid) with the treatment of organic poultry manure recorded significantly higher growth and yield parameters viz., total dry weight (135.27 g plant-1), number of pods per plant (109.38) and pod yield (85.86 q ha-1). Absolute growth rate (0.71 g plant-1 day-1), crop growth rate (6.33 g m-2 day-1) and net assimilation rate (111.86 mg dm-2 day-1) was higher in local genotype with the combination of FYM treatment which may be due to the inconsistent difference in overall growth of the crop in a month. This reflects the variable growth of the crop before pod formation stages which negatively affects the yield. Whereas biomass duration (3983.66 g days) was found higher in SARPAN-101 (hybrid) with the poultry manure treatment, it indicates the maximum biomass accumulation at harvest. Local genotype with FYM recorded the lowest biomass duration (3006.10 g days).
