Establishment of Native Grasses with Biosolids on Abandoned Croplands in Chihuahua, Mexico

Table 5

Forage dry matter production (mean ± SE) of blue grama (Bouteloua gracilis) and green sprangletop (Leptochloa dubia) under different dates at a seeded abandoned field in Chihuahua, Mexico.

Date	Blue grama (kg ha^−1)	Green sprangletop (kg ha^−1)
Growing season 2006	240±48^abB	2,297 ±  360^aA
Growing season 2007	166±37^bB	1,117 ±  159^bA
Growing season 2008	394±89^aB	1,211 ±  250^bA

Date mean values followed by different lowercase letters within each grass species are significantly different (𝑃<0.05; 𝑛=32). Grass species mean values followed by different uppercase letters within each date are significantly different (𝑃<0.05; 𝑛=32).
