  Two experiments were conducted in the laboratory with leaves of one plant species (Blumea lacera Dc.) Shiyalmutra or Kukurshunga for studying their repellency and toxicity test against the lesser grain borer (Rhyzopertha dominica F.) and rice weevil (Sitophilus oryzae L.; Bastrychidae:Coleoptera) with the attempt for chemical investigation of each extract. In the first experiment petroleum ether extract of dried leaves (1, 2 and 3% by volume) were used on the adult beetle of lesser grain borer and rice weevil to evaluate their repellency for mortality/direct toxicity effects. Results for the two experiments indicated that 1, 2 and 3% petroleum ether extract of leave of Blumea lacera Dc. species had repellency as well as direct toxicity, while 3% showed strong repellency and toxicity effects among the other extracts on both lesser grain and rice weevil.

  During germination, cultivar Monoval tolerated the salinity as well as higher temperature better as compared to Majoral, Monored and Polygroeningia cultivars of fodderbeet (Beta vulgaris). Whereas, cultivar Majoral had the lowest salinity and temperature tolerance during germination. The number of leaves, leaf length and root girth was not affected in cvs. Monoval and Monored under same soil conditions. Fresh weight of leaves and beet in cv. Majoral increased significantly over control. Chlorophyll a and chlorophyll b in cv. Majoral increased significantly. Total protein of leaf and sugar content of beet were comparatively higher under saline conditions as compared to the non-saline soil.
