Última Economic comparison of tillage and planting operations in three tillage systems CIGR Journal Akbarnia, A.; Farhani, F.; Heidary, B..  To study the economy of tillage operations and present suitable systems for land preparation and planting, costs of execution of three different tillage operations in irrigated wheat crop were compared for three successive years.  The three systems include: conventional or maximum tillage (Max-till), reduced tillage (Red-till) using multitask machine, and using direct planting machinery to represent the no-tillage case (No-till).  Costs were composed of rental cost of tractor, the used implements, multitask machine and direct planting machine.  For each case, data were compared and analyzed in randomized block design.  The variance of wheat yield in the three tillage systems was significant at the 1% level.  Total costs per hectare were 109 and 78 and 46...

Ano: 2013 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/2476 Design and performance evaluation of PHilMech multi-row onion seeder: Ten-row model CIGR Journal Dela Cruz, Renita Sta. Maria; Idago, Rodelio G.        There are several inefficiencies in the present direct seeding method of onion that are being practiced in the Philippines.  This study aimed to address these inefficiencies by developing and evaluating a tractor-hitched mechanical seeder that could efficiently distribute and plant onion seeds and reduce production cost.           Machine development was done from 2013-2016 and laboratory and extensive field evaluations in farmers’ farms were carried out in 2016-2017.  A 10-row, tractor-hitched and drill type onion seeder was developed which is capable of opening furrows, metering and delivering the seeds to the furrows, covering the seeds and firming the seedbed.  The machine was evaluated in terms of its technical performance following the...
