Abstract
The study was carried out to design, develop and evaluate the performance of an inclined seed plate for sesamum planting. To design the seed plate various physical parameters of sesamum seed were studied to design the cell size. Various materials were used for fabrication purpose on the trial and error basis, but the acrelic is most suitable material for fabrication of seed plate for sesamum. Performance evaluation of planter was carried out with acrelic sesamum plate. Various technical and economical aspects of the planter with sesamum seed plate such as seed rate, depth of planting, plant to plant spacing, row to row spacing, visible damage to the seed, uniformity index, Emergence percentage, fuel consumption and cost of operation were measured. The maximum number of seeds dropped by using inclined seed plate was 3. The performance of the planter with sesamum seed plate is satisfactory. It gives a desired seed rate obtained in the calibration test was 3.32 kg/ha. During the field trial seed damage is negligible. The planter gives row to row spacing of 44.8 cm and average depth of placement of sesamum seed was found to be 2.5 cm, which is close to recommended values of these parameter. The working width of planter will be 60 cms with a depth of 2 to 3 cm. For sowing operation fuel consumption tractor were found 5 l/ha. The percentage of the visible damaged seeds was found in the range of 0.5 to 1 %. (Average 0.5 %) which was negligible. Germination percentage of seed was found to be 72 %. Average plant to plant spacing for first row was found to be 12.4 cm and second row was found to be 13.9 cm. The average uniformity of sesamum seed placement was 79.6 %. The average emergence was observed to be 79.80 %. The cost of operation for sowing was Rs. 470 Rs/h. The overall performance of tractor operated sesamum planter during the operation carried in small area regarding seed placement was satisfactory.
Description
Sesamum (Sesamum orientale) is commonly known as “Til”. It is a short duration crop grown throughout the year. The seeds of the plant yield edible oil. India ranks first in the area of sesamum. India's contribution to the production of sesamum seeds in the world is 18.8% in 2006-07. Maharashtra is the leading sesamum producing state having area 40,000 ha and contributing 20,000 ha of total production in 2015-2016 (Krishi Sanvadini Dr. PDKV,Akola). Traditional methods of sowing of sesamum includes broadcasting manually (before broadcasting seeds are mixed in soil, sand or in cow dung as the seeds of sesamum are very small), opening furrows by a country plough and dropping seeds by hand, known as ‘kera’, and dropping seeds in the furrow through a bamboo/metal funnel attached to a country plough. But traditional method having many disadvantages including higher labour requirement, time consuming method to cover large area, also plant to plant and row to row distance is not maintained and hence more seed rate is required. To overcome these drawbacks, the planting technique of sesame must be mechanized. An attempt therefore is made to develop inclined seed metering device for sowing of sesamum seed.
