Abstract
Garlic is one of the country's important crops, accounting for about four thousand hectares annually, but due to the lack of suitable planting machines for small farms, planting is done manually, which is very expensive. Therefore, in a study, a prototype of a two-row garlic planting machine with a cup seed metering system was fabricate for planting garlic seeds in small fields, that can be connected to a tiller or small garden tractors. For the field evaluation of this machine, two factors, forward speed and garlic planting depth, were investigated using a factorial experiment in a randomized complete block design (RCBD) with three replications on the factors of machine accuracy and garlic crop yield. The results showed that the interaction effect of forward speed and planting depth on the factors of miss index, multiple index, quality of feed index and yield was significant at the 1% statistical level and on the factors of average distance between garlic cloves and density at the 5% statistical level. The most suitable forward speed was one kilometer per hour with a planting depth between 5 and 8 centimeters, or two kilometers per hour with a planting depth of maximum 5 centimeters. Based on the research results, the average values of planting distance on the row, miss index, multiple index, quality of feed index, planting density and garlic yield at a speed of one kilometer per hour were 15.6 cm, 27.8%, 7.4%, 64.8%, 21.1 cloves per square meter and 15904.2 kg per hectare, respectively.
