Abstract

An appropriate in vitro propagation medium is necessary to improve the shoot multiplication ability and seed quality in micro propagation. In the Murashige Shoog in vitro culture medium, plant growth regulator can be added as growth promoter. This study aimed to determine the best IAA concentration for in vitro culture growth of Japanese taro (satoimo). The treatment consisted of 4 IAA concentrations, i.e. I0 (0 mg / l), I1 (0.5 mg/L), I2 (1 mg/L), I3 (1.5 mg/L) in randomized block design, with 5 replicates. The results of this study showed that IAA treatment gave an effect on the time of shoot emergence, shoot number, leaf number and root number of satoimo plantlet. IAA concentration of 0.5 mg/L was the best for satoimo shoot number, whereas 1 mg/L IAA was the best concentration for shoot number, shoot height and leaf number in micropropagation of satoimo.

Abstract

The world trade history has recorded Maluku as a spice-producing region, including cloves. This commodity has high economic value and is the main source of income for farmers in several areas in Maluku Province. Climate is an environmental factor that also influences plant metabolism and physiology, so that changes in some elements of climate can have a negative impact on plant growth and productivity. The objective of this study was to get information regarding effect of climate variable on productivity of cclove in Haruku island, Central Maluku Regency. Data was collected by field srvey, while secondary data was gathered form related agencies. The results showed that the Haruku Island area with a local-unimodal rain pattern experienced an increase in annual rainfall of 11.8% in the period of 1991-2020 compared to the previous period (1961-1990). The rainy season rainfall (April-September) tends to increase by 15.2%, while the dry season rainfall (October-March) does not show a significant increase, namely only 1.3%. In the last 60 years (1961 – 2020) in the Haruku Island region, El-Nino extreme dry rainfall occurred 19 times. La-Nina wet extreme rainfall events occurred 14 times. Climate variables that affect production are the average annual length of solar radiation, the average annual relative humidity and the amount of annual rainfall

Abstract

Lesser yam (Dioscorea esculenta) is a root crop which grows and spreads in various parts of Indonesia, from Papua to Sumatra. Plant support technique using stakes is a way to support physical plant growth to control shape, size, and direction of plants. This study aimed to obtain the tuber parts as propagules of lesser yam plant (Dioscorea esculenta) and the of stakes as plant support on lesser yam yield. The research experiment was carried out using a randomized block design (RBD) which consisted of 2 treatment factors; the first factor being the plant support techniques consisted of no support, single support, and pyramidal support model, and the second factor tuber parts as propagules consisted of root, middle, and tip root cuttings. The results showed that the interaction between the tuber cuttings and the plant support model was not significant or there was no synergistic in supporting the growth and yield in the form tubers, whereas the effect of tuber cutting treatments was significant on number of tubers (12 planted tubers) and highly significant on tuber weight (1864.9 g), tuber diameter (5.84 cm) and tuber length (6.11 cm). The effect of plant support models was not significant on number and weight of tubers, however was significant on the tuber diameter (5,54cm), and highly significant on the tuber length (6.05 cm).

Abstract

Watermelon production is influential in supporting the increase of income of the farm. Watermelon production tends to decline at present, so that efforts need to be carried out to optimize the growth and yield of watermelon plants. One of the important nutrients source for watermelon plants is ‘Mutiara’ fertilizer and the plant growth regulator (PGR) gibberellin. This study aimed to determine the right combination of ‘Mutiara’ fertilizer dosage and gibberellin concentration on the growth and yield of parthenocarpic watermelon plants. This research was conducted from September to December 2023 at Pattimura Mutiara Farm of Pattimura University, in Rumahtiga Village, Teluk Ambon Subdistrict, Ambon City. This research was an experimental study that used a Factorial Randomized Group Design (RAK) consisting of two treatment factors, i.e.: ‘Mutiara’ fertilizer with 4 levels and the dose of gibberellin with 4 levels, with replications, so that there was a total of 48 treatment combinations. The observed variables included plant height, number of leaves, number of female flowers formed, fresh fruit weight, fruit diameter, and number of seeds. The results showed that the interaction between the dose of ‘Mutiara’ fertilizer 6 g/plant and the concentration of gibberellin 6 mL/L was the best treatment combination and could increase plant length and number of leaves. The combination of 2 g of ‘Mutiara’ fertilizer and 2 mL/L gibberellin concentration was the best combination for fresh fruit weight

Abstract

The use of chemical fertilizers on vegetable mustard by farmers is currently higher than the use of organic fertilizers. The use of proper organic fertilizers is an alternative to reducing the dose of chemical fertilizers to increase yields of pagoda mustard. This study aimed to determine the effect of biological organic fertilizers at various treatment doses on the growth and yield of pagoda mustard. This study was conducted in the Greenhouse of the Faculty of Agriculture, Pattimura University, from May to July 2019. It was carried out using single factor experiment in a Randomized Block Design, with biological organic fertilizer dose treatment, consisting of 6 levels: 0 ml/l, 5 ml/l, 10 ml/l, 15 ml/l, 20 ml/l, and 25 ml/l per container. The observed variables consisted of plant height, number of leaves, leaf area, crown fresh weight, root fresh weight, crown dry weight, and crown diameter. Data were analyzed statistically and further tested using Duncan's test with a level of 5%. The results showed that the treatment of biological organic fertilizers had a very significant effect on the observed variables of root fresh weight. The fertilizer dose significantly affected the observed variables of leaf number (28 and 35 days after planting, dap, ie after the plants were removed from the nursery), plant leaf area, crown fresh weight, crown dry weight, and plant crown diameter, but had no significant effect on the observed variables of plant height (14 and 21 dap) and number of leaves (14 and 21 dap).

Abstract

‘Kisar’ orange is one of oranges from ‘Kisar’ Island, Southwest Maluku District. Optimizing media composition for orange micropropagation is indispensable to enhance propagation or multiplication ability and seedling quality. This research aimed to study the effect of combination of plant growth of shoots of ‘Kisar’ orange and get the optimal combination. The research material were ‘Kisar’ orange explants from previous shoot cultures on MS medium. The materials for this study were explants of Kisar orange that were previously subculttured on MS medium. This descriptive study involved the use of combination of four treatment levels of kinetin and NAA consentrations,with three replication treatments of kinetin and NAA, consisting of 0,00 µM (control), 0,50 µM, 0,75 µM and 1,00 µM. The results showed that kinetin and NAA treatments in the in vitro culture medium gave different effects on shoot growth of ‘Kisar’ orange. The combination 1,00 µM kinetin and 1,00 µM NAA was the best combination for in vitro shoot growth of ‘Kisar’ orange, while the combination of 1,00 µM kinetin and 0,50 µM NAA was the best for the number of internodes and leaves, and medium with 0.00 µM kinetin and 0.75 µM was the best for explant height.
