Abstract:
Abstract:
Leguminous crops are very sensitive to mechanical abuses. Furthermore, chickpea is more prone for This invention relates to an improved neem larvidical composition for use as such in the solution or
mechanical damage due to its germ tip located at protruding structure and are dicotyledonous. Even minor emulsifiable concentrate or a derivative having slow release properties comprising of composition
injury to seed affects seed quality adversely. Hence, a conventional cylinder and concave cannot be used to having an active constituent selected from neem pesticide alongwith thymol or p-cymene singularly or in
thresh chickpea seed crop. In general, pulse production and productivity is low world over and more so in combination along with the requisite auxiliaries. The active ingredients have been found to synergistically
developing countries (Jeswani and Baldev, 1990). One of the important reasons for low pulse productivity affect the control of the larvae of Culex fatigans.
is non- avialability of quality seed. The aviability of quality seed, of chickpea is least i.e. about 2 per cent,
among all the major crops of the country. However, it had been reported that about 20- 30 per cent
average increase in productivity could be achieved with the use of quality seed (Chowdhary, 2004). Varying
operational parameters such as cylinder speed, cylinder-concave clearance, fan speed helped to limited
range in threshing but with induced significant amount of visible damages. In light of above facts, the
new thresher was developed to thresh chickpea of high seed quality attributes i.e. maximum germination
percentage; vigour and viability and minimal visible as well as invisible injuries. These quality attributes
are dependent on operational parameters and design parameters of thresher. The optimum operational
parameters of cylinder speed, beater type, feed rate, moisture content and concave clearance was 8.94 m/s,
Teflon or nylon beater, 200 kg/h, 10 per cent and 14 mm, respectively. The specially configured threshing
cylinder using Teflon beater/ threshing element produced seed of germination capacity (98), vigour (1800)
and viability (98) coupled with minimal visible breakage (1.17) and internal injury (0.03) with optimum
threshing efficiency (98).
