Background: Dermatophytosis has been a common contagious disease and remain an important public health problem among people worldwide and particularly in developing countries. This study was done in order to know prevalence of keratinophilic fungi in the soil samples of Ajmer region and its clinical correlation. Materials and Methods: Five samples (5gm each) of garden soil were collected from each of the randomly selected 10 sites of Ajmer region in sterile polythene bags & pH of soil was recorded. All samples were processed in the laboratory using hair bait technique and incubated at 28 + 2•C for 3-4 weeks. Fungi grown were subcultured onto Sabourauds Dextrose Agar (SDA) with chloramphenicol & SDA with cycloheximide and identified using standard mycological procedures. Results: Out of 50 soil samples cultured 28 (56%) samples were positive for keratinophilic fungi. 64.28% were dermatophytes and 12.8% were non-dermatophytic fungi. The predominant isolate among dermatophytes was Trichophyton spp. (64.28%) where as Aspergillus spp. (12.8%) was the commonest non-dermatophyte. Conclusion:In our hospital, dermatophytic infection including Tinea corporis is one of the most common clinical presentations of skin infection. Trichophyton spp. is commonest causative agent of Tinea corporis. Interestingly Trichophyton spp. was the most commonly isolated dermatophyte in our study suggesting soil as a source of dermatophytic infections.

Seed sowing is an essential and time-bound process agriculture. The basic objective of the sowing operation is to put the seed in rows at the desired depth and maintain seed to seed spacing, covering the seeds with soil and providing proper compaction over the seed. Early or postponed sowing adversely disturbs the crop yield. Therefore, the sowing of seeds in the optimum level is important to ensure more outcomes and high quality of crops. At present, the maize planting is done manually by broadcasting, dibbling, putting seed behind the plough, and other methods or with the help of animal or tractor-drawn seed drills/planters. Though, these techniques have many problems, such as worse efficiency and reduced quality seed placement. Currently among different sowing methods, dibbler planter delivers more uniform and adaptable seed spacing than other approaches for sowing hybrid seeds. But available dibbler planter has some shortcomings of lower field capacity. By considering the apparent advantage of the dibbler planter mechanism, the power-operated dibbler planter for pulse crop was modified and improved to minimize the problems of the existing dibbler planter. Henceforth, the two-row power-operated dibbler was designed and developed to promote mechanization of maize planting operation among small and marginal farmers.
