NABL certificate was alsoobtained for detection of organochlorine pesticide residues.In another activity on heavy metal analyses, the earlier validated detection method was used toinvestigate the metal load in herbal drugs of Himalayan region. The results revealed that the loadswere well below the permissible limits specified by the Prevention of Food Adulteration Acts& Rules (PFA) in all but one sample. In analyses of leaf samples from Banuri tea garden, Mnfollowed by Fe, Zn and Cu were the most detected essential metals. The toxic heavy metals (Pb,Cd and Ni) were too low or undetected in tea leaves, made tea and infusions.Farm mechanizationThe performance of the skiffing machine STIHL 81 was evaluated for the second year. Thebenefit-cost ratio (BCR) was worked out to be 1.34, 1.53 and 1.63 for level-off skiff, light skiffand deep skiff, respectively. In another study, a pruning machine OTC 4300 weighing 7.3 kg with250x100 mm P-tipped saw blade and a rotating action blade was evaluated. The BCR for collarpruning was worked out to be 1.96.43
