The interest, use, and recognized benefits of gardens as educational tools for youth has increased in recent decades and has prompted the development of garden-based curricula for use in schools. Iowa State University Extension developed Growing in the Garden (GITG), a curriculum designed for use in kindergarten through third grade classrooms. This study examined the impact of the GITG curriculum on the awareness and interest of first graders in the areas of science, nutrition, and the environment. A survey was used to determine parental perceptions of their child's interest and awareness after experiencing three lessons from the GITG curriculum. Forty-seven parents (60.2% response rate) of first graders from four classrooms in Iowa completed the survey. A significant number of parents surveyed noted an increased awareness and interest of their children in the areas of science and the environment. Factors such as socio-economic status, ethnicity, and gender did not influence the outcomes.
The interest and use of gardens as educational tools for youth has increased in recent decades. The positive connection found between children and horticulture has prompted the development of garden-based curricula for use in schools. Iowa State University Extension developed the Growing in the Garden (GITG) curriculum for use in kindergarten through third-grade classrooms. This study examined what impact the GITG curriculum had on the awareness and interest of first graders in the areas of science, nutrition, and environmental awareness. Impact was assessed by a parental survey asking for perceptions of their child's interest and awareness after experiencing three lessons from the GITG curriculum. The sample population consisted of 78 parents of first-grade students from four classrooms in Iowa. The response rate was 60.2%. Results indicate that a significant number of parents completing the survey noted an increased awareness and interest of their children in the areas of science and the environment. Factors such as socioeconomic status, ethnicity, and gender did not influence the outcomes.
The objective of this study was to determine the efficacy of plant growth regulators applied as foliar sprays on height and branching of seashore mallow (Kosteletzkya virginica). Five chemical plant growth regulators were applied: ancymidol [15, 25, and 50 mg·L–1 (ppm)] (A-Rest; Elanco Products Co., Indianapolis), dikegulac sodium (500, 1000, and 1500 mg.L–1) (Atrimmec; PBI/Gordon Corp., Kansas City, Mo.), paclobutrazol (10, 20, and 60 mg·L–1) (Bonzi; Uniroyal Chemical Co., Middlebury, Conn.), chlormequat chloride (CCC) (750, 1000, and 1500 mg·L–1) (Cycocel; Olympic Horticultural Products, Mainland, Pa.), and CCC/daminozide mixes (1000/2500, 1000/5000, and 1500/5000 mg·L–1) (Cycocel and B-Nine; Uniroyal Chemical Co.). Ten replicate plants of each concentration were evaluated weekly for plant height and number of branches for 8 weeks. Plants that received CCC and CCC/daminozide treatments at all concentrations and paclobutrazol at 60 mg·L–1 were 60%, 60%, and 48% shorter than control plants and had 113%, 100%, and 75% more branches than control plants, respectively. All concentrations of ancymidol and dikegulac sodium-treated plants were similar to control plants. Paclobutrazol was applied twice, and only the highest concentration was effective for height control. Chlormequat chloride at the lowest concentration was as effective as all other concentrations of CCC and CCC/daminozide.
