The exact date of this introduction is argued. Hormicide). The dispersal pattern of a weed Tridax procumbens wasinvestigated in an agricultural field. They limit the productivity of the lands and hence affect crop development and yield. The preferred basic diet for guinea pigs is unlimited amounts of Timothy or other low-calcium hay, supplemented with smaller amounts of a commercial, high-fiber, Timothy-hay based guinea pig pellets. Wind Guinea grass genotype BG‐2 produced higher dry‐matter yields than BG‐1, both in monocropping and in intercropping. Fire destroys the living plant material in any area making those sites perfect for new seeds to grow. For instance spear grass has spiky tips that can get stuck in passing animals or blown by a strong wind to a new place. Site-species matching This is the weakest part of ANR, as there is limited knowledge of the specific ecological requirements of natural forest tree seedlings (Kartawinata et al., 2001). Another way for animals to help in seed dispersal is for the animals to actually plant the seeds themselves. Guinea grass yields an average of 30 t DM/ha/year (Cook et al., 2005). H01, N.
