Abstract

The research on the influences o f the planting season on growth, yield o f Sachi in Spring - Summer season, 2018 at Trieu Son district, Thanh Hoa province. The experiment was designed in randomized complete block (RCB) with four treatments and three replications in Spring- Summer season 2018. The treatments were included with 4 planting seasons such as 1) The planting season 1 (TV1): The sowing date was on 5th of June, 2018 and the planting date was on the 9th o f July, 2018; 2) The planting season 2 (TV2): the sowing date was on the 20th o f June, 2018 and the planting date was on the 24th o f July, 2018; 3) The planting season 3 (TV3): The sowing date was on the 6th o f July, 2018 and the transplanting date was on 9/h of August, 2018; 4) The planting season 4 (TV4): the sowing date was on the 21st of July, 2018 and the transplanting date was on the 24th o f August, 2018. The planting density was 3.333 plants/ha. The study result showed that after four times harvesting, the real seed yield o f Sachi o f the planting season 3 (TV3) obtained the highest (5.21 tons/ha), and higher than other treatments at a statistically significant probability with LSD0j)5= 0.26 tons/ha. In addition, the Sachi o f the planting season 3 had highest ability tolerance o f disease. To summary, the sowing date was on the 6th of June, 2018 and the transplanting date was on 9th of August, 2018 that was suitable for Sachi grew and got the highest yield at Trieu Son district, Thanh Hoa province.
