Respons Empat Varietas Gladiol (Gladiolus hybridus L.) Terhadap Perendaman Benziladenin dalam Meningkatkan Pertumbuhan Tunas dan Produksi Subang0.

Gladiolus is a potential ornamental plant to be widely developed because its high aesthetic value. Generally, gladiolus is propagated vegetatively by using tuber that called corm. There are some problems in gladiolus vegetative propagation, which is corm has a dormancy period and produces only one to two corms for each gladiolus plant. The effort that can be done to solve these problems is to provide benzyladenine to gladiolus corm. This study aims to determine the response of four varieties of gladiolus (Gladiolus hybridus L.) that soak to benzyladenine in increasing the growth of shoot and corm production. This research was conducted in Bandar Lampung in 2017. The treatment was designed factorially (4 x 4) using Randomized Block Design. The first factor was the varieties of gladiolus ie Anisa, Clara, Nabila, and Nurlaela. The second factor was the 100 ppm concentration of benzyladenine in repeating ie first, second, third, and fourth soaking. Data analysis was tested by Least Significant Difference (LSD) test at 5% level. The results showed that (1) from four gladiolus corm varieties, Nabila produced the highest number of shoots at 10,34 shoots, while the variety that produces the highest number of corm was Clara at 5,71 corms, (2) the benzyladenine that used up to four times for soaking the corm resulted the same response in increasing growth of shoot and corm production of four gladiolus varieties, (3) the response of each gladiolus varieties didn’t depend on how many times that benzyladenine used to soak the corm in increasing the growth of shoot and corm production of four gladiolus varieties.

Effect of Different Dose of Nitrogen and Phosphorous on Gladiolus Yield at Ilam, Nepal

An experiment was conducted to assess the effect of different levels of nitrogen and phosphorus on Gladiolus yield of cultivar (cv.) Jester in Ilam municipality-2 Fulgachi, Ilam. The research was conducted at the Department farm of Bachelors of Science in Horticulture and Floriculture Management (B.Sc. HFM), Ilam from April to September 2014. The experiment consisted of twelve treatment combinations laid out in factorial randomized complete block design with three replications. Four levels of nitrogen 0 kg, 50 kg, 100 kg and 150 kg/ha were experimented as the first factor and three levels of phosphorous 0 kg, 50 kg and 100 kg/ha formed were taken as the second factor which comprised of twelve treatment combinations. Nitrogen and phosphorous significantly affected plant height, number of leaves per plant, spike length, days to first cutting, days to last cutting and yield (number of corm per plant) of Gladiolus plant.

Preemergence Weed Control in Gladiolus Cormels

Multiple applications of several preemergence herbicides were evaluated for weed control and for phytotoxicity to gladiolus (Gladiolus X hortulanus L.) grown from cormels in 1984 and 1985. Oryzalin [4-(dipropylamino)-3,5-dinitrobenzenesulfonamide] consistently provided acceptable control of southern crabgrass [Digitaria ciliaris (Retz.) Koel. # DIGSP], goosegrass [Eleusine indica (L.) Gaertn. # ELEIN], and smooth pigweed (Amaranthus hybridus L. # AMACH) and had minimal effect on gladiolus plant growth even after four applications. Pronamide [3,5-dichloro (N-1,1-dimethyl-2-propynyl)benzamide], alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide], and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] provided erratic weed control and reduced yields of gladiolus corms.
