Abstract

Chlorophyll is a pigment of photosynthesis which is also efficacious as a cure for brain, lung, and oral cancer, and can be used as a disinfectant, antibiotic and dietary supplement, while carotenoids are useful as antioxidants. The content of the two pigments is strongly influenced by the age of the plant, especially for vegetable crops used in leaves such as cowpea (Vigna unguiculata (L.) Walp.). The purpose of this research is to know the pattern of chlorophyll content and carotenoid of cowpea leaf during the growth phase and to know the age of the right plant for harvesting cowpea so that the highest chlorophyll and carotenoid content is obtained. Cowpea seeds obtained from seeds are added then planted in pots containing ready-made planting media in the greenhouse. Chlorophyll and carotenoid analyzes were performed at different plant ages from 1 to 11 weeks. The research design used is Completely Randomized Design. Data were analyzed using variance analysis and continued with Duncan test at 95% significance level. The results showed that the highest chlorophyll and carotenoid content was produced by the cowpea leaf in the vegetative phase or before the flowering time. The highest chlorophyll content was obtained at 4WAP (weeks after planting) of age crop, while the highest carotenoid content was obtained in 3WAP.

Abstract

Fertilizers are needed to encourage the growth of orchids because their growth is known to be very slow. Monosodium glutamate (MSG) is a crystalline salt containing sodium and glutamate which can stimulate plant growth. Therefore in this study, the application of MSG and fertilizer was carried out to promote the growth of D. stratiotesorchids. The application of MSG and fertilizer was given in a completely randomized design with a factorial pattern consisting of MSG concentration factors (0, 0.5 and 1%) and fertilizing factors (not fertilized and fertilized). There are six treatments and three replications per treatments. The parameters observed increased in leaf length (cm), the morphological response of orchid plants in the form of new shoot formation, new root formation, and bulb enlargement. Results of research and test Analysis of Variance (ANOVA) showed no interaction between MSG and fertilizer in influencing the length leaf orchid D. stratiotes. The length of leaves is highest in orchids by MSG 1% without fertilizer, while the formation of new shoots and bulb enlargement occurred in orchid plants which were given 0.5 and 1% MSG without fertilizer application. New root formation occurs in plants given MSG and fertilizer. The conclusion is the application of 1% MSG without fertilizer can promote the growth of. D. stratiotesorchids.

Abstract

Red spinach is (Alternanthera amoena Voss.) a vegetable that contains vitamins (vitamin A, C, and E) and minerals.Yield optimization red amaranth cultivation can be done with additional supplementary fertilizer like fertilizer leaves Gandasil D. The purpose of this study are to examine the effect of Gandasil D fertilizer on vegetative growth of plants and determine the optimal concentration of Gandasil D fertilizer on the chlorophyll and carotenoid content of the leaves. The experiment was carried out by germinating red spinach seeds, transferring 14 -days-old seedlings into pots containing planting media and basic fertilizers.  Seedlings at 14-days-old were then given Gandasil D fertilizer by spraying on the surface of the leaves once a week until the age 32–days-old. The study was conducted with a CRD with a single factor with 4 treatments of Gandasil D concentration, namely 0g/L (control), 1g/L, 2g/L, and 3g/L with 5 replications.  Parameters observed that the number of leaves, plant height, root length, wet weight, dry weight, chlorophyll, and carotenoid content.  Data were analyzed by ANOVA followed by Duncan’ test at the 95% significance level. The results showed that the application of Gandasil D significantly affected the number of leaves, plant height, and fresh weight of the plant.  Spraying with Gandasil D did not show a significant effect on root length, plant dry weight, and chlorophyll and red spinach carotenoid content.  Gandasil D fertilizer at a concentration of  3g/L produces the most optimal growth of red spinach plants.
