Design and development of ICAR-NRRI urea applicator for rice transplanter

Nenavath Manikyam, Prabhat Kumar Guru, RK Naik

Mechanization in rice transplanting is utmost important to overcome labour shortage. Urea is the most important and highly used fertilizer in rice production. Urea applicator was designed for self-propelled transplanter to place the urea in briquette form to minimize the losses and to avoid one manual operation of fertilizer application. Engineering properties of urea briquettes were measured to get the optimum values for designing the metering unit. Metering unit was designed with cup diameter and depth as 20 mm and 5.5 mm on the basis of maximum length (16.59±1.284) and thickness (9.3±0.249) of urea briquette. Self-propelled rice transplanter with urea applicator at speed of operation of 1.66 kmph the field capacity and field efficiency of were 0.191 ha h-1 and 67.82% respectively and fuel consumption was 1.81 l h-1. The percentage of missing, floating and buried hills were 10%, 3.75% and 2.5% using self-propelled rice transplanter working with urea briquette applicator.
