Vegetables are vital for human health and are consumed five days a week in ***,the production cannot meet domestic demands due to labor-intensive farming and production costs related to soil *** is needed along with soil quality and sustainability improvements by the adoption of CA(Conservation Agriculture).The research aimed to compare the performance of the no-till vegetable transplanter with punch-planter in CA and hand transplanting in CT(Conventional Tillage).The study was conducted at the Royal University of Agriculture,Cambodia,starting from January to September 2020,by firstly growing sunn hemp as a cover crop and then transplanting Thai round eggplant.A randomized complete block design was used with three treatments,replicated three *** plot was 2 m by 15 m,with 0.2-m row *** results showed that the transplanter speed was 0.54 km􀁸h^-1,almost two times the speed of punch planter and 9 times the speed of hand *** highest working capacity was also achieved with the ***,different transplanting did not affect plant spacing,or plant *** spacing was 1 m,and plant density varied from 10,300 to 11,500 plants􀁸*** growth and yield were also not influenced by the transplanter in CA,or hand transplanting in *** fruit diameter,fruit weight,fruit number,and yield were 38 mm,31.4 g􀁸fruit-1,15.7 fruits􀁸plant-1 and 3.9 t􀁸ha-1,*** maximum working area of the transplanter and its break-even area were 25.2 ha·y^-1 and 18.3 ha·y^-1,*** the no-till transplanter may save both time and labor,but its use in combination with CA was unlikely to affect plant growth and yield in the short term.
