Field experiments conducted during kharif 1992, summer and rabi 1993 at Agricultural Research Station, Bhavanisagar with 4 levels of sulphur (0, 15, 30 and 45 kg ha¹) and 4 levels of magnesium (0, 15, 30 and 45 kg ha'') showed that sulphur fertilization at 45 kg ha¹ increased the seed yield of sunflower significantly over control by 6.2 per cent in summer, 9.1 per cent in rabi and 14.5 per cent in kharif. The effect was more pronounced in kharif grown crop followed by rabi and summer. Added Mg failed to exert any influence. Similar influence was observed in stalk yield also. But in terms of percentage, the responses were 46.0, 32.4 and 5.1 per cent over control during kharif. rabi, and summer, respectively. Due to sulphur application at 45 kg ha" the oil yield was increased by 17.1 per cent in rabi followed by kharif (11.5 per cent) and summer (9.5 per cent).

Effective control of the quality and safety of livestock products is possible only with the implementation of a scientifically grounded complex of veterinary and sanitary and general economic measures. The goal of our work was to develop effective ways to sanitize clothing and footwear of workers in the livestock industry. The studies were carried out following the current methodological approaches that are used in agriculture and veterinary medicine. Based on the results of the research carried out, two methods and one device have been developed to ensure a high level of veterinary and sanitary measures in animal husbandry. It has been proven that for the sanitization of clothing of workers in the animal husbandry industry, it is effective to use a disinfectant, which includes the sodium salt of dichloroisocyanuric acid (0.09–0.36%), adipic acid (0.01–0.04%), sodium bicarbonate (0.01–0.04%), sodium carbonate (0.003–0.01%), water (99.887–99.55%) when exposed for 30 minutes. For disinfection of workers' footwear, it is advisable to use disinfectants filled with a disinfectant that contains dichlorantin (0.021–0.21%), 5,5-dimethylhydantoin (0.0164–0.164%), a dispersant (0.012–0.12%), anionic surfactants (0.005–0.05%), corrosion inhibitor (0.01–0.1%), filler (0.0356–0.356%) and water (99.9–99.0%). An innovative device for cleaning and disinfection is proposed - a shoe disinfector, which consists of a waterproof box with a bottom wider than the top, filled with a disinfectant solution, a branch pipe for removing waste solution, a brush shaft, which is fixed in the upper part of the waterproof box, an electric motor with a rotational speed 2 rev/s., Which serves as a drive shaft brush, control panel with a start button and a stop button. The proposed developments complement the existing regulations on veterinary and sanitary measures at livestock farms and complexes.
