ABSTRACT :

The present paper with the help of secondary sources of data attempts to capture the major events that shaped the course of cooperative movements in Odisha. The paper portrays the prevailing socio-economic factors and key events which contributed to the development of cooperatives in different phases and its genesis and growth trend in Odisha in the national perspectives.

ABSTRACT :

The key pests of okra are whiteflies, jassids and shoot and fruit borer. The sucking pest, Sweet potato whitefly, Bemisia tabaci causes damage directly through feeding and indirectly by the transmission of viruses. The whitefly B. tabaci transmitted Okra enation leaf curl virus (OELCV) incidence has reached serious proportions in recent years. The comparative field study results revealed that, both 30 and 60 days after sowing (DAS) okra accessions Upl mona 2 and Co 1 recorded the lowest mean population of whiteflies and leaf hoppers under the IPM adopted plot and farmers practice adopted plot, whereas the highest mean population of whiteflies and leaf hoppers was recorded in AE 64 and AE 65 under both the conditions. The shoot and fruit borer damage in the IPM and farmers practice adopted plots with the lowest fruit damage being on Co1 (10 %) under IPM condition. The highest mean population of coccinellids and spiders were recorded under IPM condition. In the IPM adopted plots, both at 30 DAS and 60 DAS, the accession Upl mona 2 did not show any signs of OELCV and BYVMV infections and were immune in reaction (0% PDI) and Upl mona 2 recorded the maximum yield (6058 kg/ha). At 60 DAS, the Co 1 plants registered 20 and 40% incidence of OELCV under IPM and farmers practice, respectively.
