Abstract

Api-api plant (Avicennia marina) is one type of plant found in mangrove forest vegetation. It grows in tidal areas with muddy, loam and sandy soil conditions. The growth and development of this plant is also influenced by the salinity of the water. To develop this plant, the obstacles faced in addition to its habitat which is in the tidal area which is strongly influenced by water salinity, also not much effort to cultivate this plant outside its habitat. The aim of this reasearch was to determine the response of the use of various kind of growth media such as soil, sea sand, river sand dan mixture of soil and sea sand to the growth of Api-api (Avicennia marina) seeds. The research was carried out using a Randomized Block Design (RBD) with 5 treatments and 5 replications consisting of 5 levels of growth media treatment. The data were analyzed by means of variance and to determine the mean value of the treatment, the Least Significant Difference (LSD) test was carried out at the 5% level. The results of this reasearch concluded that differences in growrth media had a higly significant effect on the growth of api-api seeds. Growth media that consist of mixed with soil and sea sand media and sea sand media showed better results in plant growth variables which include viability seed, number of leaves, plant height, stem diameter, root length, wet weight and dry weight of the plant.

Abstract

Sweet potato (Ipomoea batatas L.) is a plant that has the potential to replace rice as a staple food. Efforts can be made to increase the yield of sweet potato production by fulfilling nutrients such as potassium fertilization, as well as turning the stems to prevent the production of tubers in each segment. The purpose of this study was to determine the effect of various doses of potassium fertilizer and time to turn the stems and their interactions on the growth and yield of sweet potato plants. This study used a randomized block design (RAK) with the first factor, namely the dose of potassium (KCl): 50 kg ha-1 (k1), 100 kg ha-1 (k2), and 150 kg ha-1 (k3). The second factor is the time of the stem reversal, namely: no reversal (po), 4 wap and 8 wap (p1), 8 mst and 12 wap (p2). The analysis of the observational data used ANOVA with the LSD further test with p <0.05. The results showed that various doses of potassium fertilizer had different effects on the growth of sweet potato plants. It is known that the KCl fertilizer dose of 50 kg ha-1 gives the best effect, namely giving the highest number of roots and the highest wet stubble weight. At the time of stem reversal, it was known that the reversal time of 4 WAP and 8 WAP had the best effect, namely increasing the highest dry weight, and there was no interaction between the dose of potassium fertilizer and the time of stem reversal on the growth and yield of sweet potato plants.
