Grown in Different Nitrogen Dozes and Row SpacingsAbstract: This study was conducted to deterrnine the appropriate of row spacing, nitrogen dozes and some characteristics of lesser burnet in a "Split Plots in Randomized Block" desing with 3 replications grown on shallow and slopy lands in Samsun Province from 1995 to 1997. In this study O, 4, 8, 12 kg/da nitrogen dozes and 30, 45 cm row spacings ware applied to plots. Two cuttings were taken both 1996 and 1997 under rainfed conditions. In the second year (1997), the yields were increased significantly. Average 1970.4 kg herbage yield, 746.0 kg hay yield and 131.7 kg crude protein yields per decar were obtained. The highest yields ware obtained from the plots with 30 cm row spacing and 8-12 kg/da nitrogen fertilization program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
