Research on growth and development of new hybrid maize varieties in the spring of 2018 at some provinces in northern and north central region

The researchers evaluated the growth and development abillity of some hybrid maize varieties grown in Spring 2018 in 4 northern and north central provinces including Viet Tri - Phu Tho, Vinh Tuong - Vinh Phuc, Phu Yen - Son La, Yen Dinh - Thanh Hoa. The experiments were arranged in a completely randomized block format with 3 replicates. Each hybrid maize was cultivated in 4 rows in a 5-m long plot; the distance between two rows was 70 cm and the distance between two plants was 25 cm. Fertilizers applied generally for experiments were 150 kg N + 90 kg P2O5 + 80 kg K2O/ha. The results showed that the growth time of experimental hybrid maize varieties in Viet Tri - Phu Tho ranged from 122 to 127 days, in Vinh Tuong - Vinh Phuc ranged from 117 to 120 days, in Phu Yen - Son La fluctuated from 113 to 116 days, in Yen Dinh - Thanh Hoa from 97 to 105 days. | Research on growth and development of new hybrid maize varieties in the spring of 2018 at some provinces in northern and north central region
