Título:  The effect of nirogen rate and clipping frequency upon the yield, protein content and certain morphological characteristics of Coastal Bermudagrass (Cynodon dactylon, (L) Pers.)

Conteúdo:  A 5-year-old of Coastal Bermudagrass growing on a Tifton sandy loam soil was subjected to treatments consisting of 5 rates of N (0, 100, 300, 600, and 900 pounds per acre annually) in all possible combinations with 5 clipping intervals (2, 3, 4, 6, and 8 weeks). In addition, treatment receiving 600 pounds of N per acre annually was clipped weekly. The hay production, proteina percentage, protein production, and percent N recovery were determined for these treatments during the unusually wet year of 1953 and the record dry year of 1954. Nitrate analyses were made of selected samples in the spring of 1953. Morphological measurements made in 1953 included total stem lenght of longest leaf-blade per stem, number of internodes per stem, leaf percentage, percent of stems in observed samples containing seed heads, and lenght of internodes per stem. Average plant height before cutting was measured in 1954. Generally, increasesd in N rate increased the hay yield, protein percentage, protein yield, and nitrate content of this hybrid Bermudagrass, but reduced the percent of N fertilizer recovered in the hay. Increasing the N rate resulted in increases in stem length, plant height, length of longest leaf-blade per stem, number of internodes per stem, and length of internodes, but resulted in decreases in leaf percentage and percent of stems with seed heads. Increasing the length of the clipping interval increased the hay yield and lowered the protein percentage, but had little effect o... Mostrar Tudo
