What are the high-yield early-maturing corn varieties? A must-read for growers choosing seeds
Growers who plant corn all know that corn is divided into early-maturing corn, mid-maturing corn and late-maturing corn. Generally, varieties that mature 25 to 34 days after pollination are early-maturing varieties, those that mature 35 to 40 days after pollination are mid-maturing varieties, and those that mature only after 40 days are late-maturing varieties. In order to obtain a lot of economic benefits, many growers who plant corn choose early-maturing varieties, so what are the high-yield early-maturing corn varieties?
1. Xianda 202
Characteristics: The growth period for re-sowing is about 92 days, and the growth period for spring sowing is about 110 days, suitable for both re-sowing and spring sowing; plant height is about 270 cm, ear height is about 100 cm, plant type is semi-compact, cob is red, kernels are dent type, and the ear dehydrates quickly.
