Caladium × hortulanum Birdsey `Candidum' tubers were forced in pots until at least one-half the visible sprouts were 2 cm above the soil surface. These prefinished plants were subjected to simulated transit durations of 2, 4, or 6 days in the dark at 12.5, 15.5, 18.5, 21.0 or 24C. Plants were then grown for 4 weeks in a greenhouse and were either fertilized weekly with 100 ml of a solution containing 500 N-218P-415K (mg·liter-1) or were not fertilized. Interactive effects between transit duration and temperature were significant for all measured growth responses. Transit temperature maintained for 2 days had little effect on subsequent growth and only moderate effects after 4 days. With transit duration of 6 days, an increase in temperature resulted in increased plant height, fresh weight, number of leaves, white coloration of leaves, and percent of plants judged marketable (finished) in 4 weeks. Holding at ≈ 18.5C was most favorable for transit durations of 4 or 6 days. Use of fertilizer during finishing improved plant growth regardless of transit conditions, but did not totally negate deleterious effects from transit conditions.

Nonplanted Caladium × hortukmum Birdsey `Candidum' tubers were exposed to 26 (control), 38,43, or 48C for 1,2, or 3 days. Then tubers were planted and forced in a glasshouse for 4 weeks at 18 to 33C (air). Leaf emergence from tubers exposed to 48C for 1 or 2 days required 3-12 days longer than leaf emergence from control tubers. No leaves emerged from tubers treated at 48C for 3 days. Exposing tubers to 38C for 3 days or 43C for 1 day did not affect subsequent plant growth. Exposing tubers to 43C for 2 or 3 days or 48C for 1 or 2 days resulted in plants with reduced shoot fresh weights and fewer leaves ≥ 15 cm. In a second experiment, planted tubers were forced for 10 days at 26C so that roots had developed to the edge of the pot and shoots had emerged to the soil surface. These planted (sprouting) tubers were exposed to 43C for 0,4,8,12,16,20, or 24 hours/day for 1,3, or 5 days and then forced for 7 weeks in a glasshouse. With 3- or 5-day treatments, days to leaf emergence increased as the hours of exposure to 43C increased. Only 33% of planted tubers exposed to 43C for 24 hours/day for 5 days sprouted. Tubers exposed to 43C for≤ 12 hours/day for 3 days produced plants of similar or greater height, numbers of leaves □≥15 cm wide, and shoot fresh weights, but additional hours of daily exposure decreased these plant characteristics. At 5 days, plant height, number of ≥ 15-cm-wide leaves, and shoot fresh weight decreased linearly with increased hours of exposure of tubers to high temperature.

<p>Indonesian society has a consumption pattern dominated staple grains group. To reduce dependence on other countries for imports of foodstuffs, need to diversification their meal using existing biodiversity. One of the crops that can be developed is the cocoyam (Xanthosoma spp.) potential as a source of carbohydrate. Cocoyam can be grown in the lowland to the mountains with a height of up to 1300 meters above sea level. Therefore it is necessary to find the most appropriate planting site so that plants can grow and develop optimally. This study aimed to determine the growth of three types of new cocoyam at a different altitude variation. This study was conducted in two different regions of altitude, is Tawangmangu (1200 m above sea level) and Klaten (98 m above sea level). Observations using three different types of cocoyam, the tuber white, purple and yellow. Each type grown in both altitude with 10 replications each. The observations were obtained include fresh weight, dry weight, number of leaves, chlorophyll and carotenoid levels were analyzed by unpaired t test and ANOVA test at 95% confidence level. The results of this study indicate that tuber white, purple and yellow tuber are planted in the lowlands (Klaten) and highlands (Tawangmangu) had significant results in the measurement of plant height, fresh weight, dry weight, and chlorophyll and carotenoid levels have significantly different results, but not the parameters of the number of leaves. Height and weight of the fresh plant<br />in Klaten higher than in Tawangmangu, while the white tuber dry weight in Tawangmangu higher than other treatments. The levels of chlorophyll and carotenoid yellow tuber is the highest in Klaten than others.</p>

Overfertilization on leafy vegetables could accumulate high nitrate content. Exceeded recommended limit of nitrate content can cause detrimental effects on the environment and human health, such as methemoglobinemia and stomach cancer. Green coral lettuce (GCL) is a leafy vegetable commonly grown under various production systems. Production system and physiological age have affected the growth and accumulation of nitrate levels in most leafy vegetables. Therefore, this study aims to determine the effects of hydroponic and conventional production on the growth performance and nitrate concentration of GCL at different harvest ages. This research was conducted in a randomized complete block design with a factorial arrangement of treatments. A stagnant hydroponic was prepared using stock A and B complete Hoagland nutrient solutions as liquid fertilizer. A commercial biofertilizer (NPK 8: 8: 8) was applied at the rate of 100 g per plant. Plant growth performance, including plant height, number of leaves, and leaf length, was measured at 7, 14, 21, 28, 31, 34, 41, and 44 days after transplanting (DAT). The fresh weight and nitrate content were measured at 31, 34, 41, and 44 DAT. The results showed hydroponic GCL exhibited higher plant height than conventional GCL. However, both productions were not significantly affected regarding the number of leaves, leaf length, and fresh weight. At 41 and 44 DAT, the hydroponic GCL was markedly higher in nitrate content than conventional. This study found that conventional production was recommended for GCL because lower in nitrate content compared to hydroponic and fair in growth performance.

Potential development of medicinal plants in Karanganyar is very large, because this area is famous as a center of medicinal plants such as ginger, turmeric, kencur, and temulawak. In the development of medicinal plants, the approach of organic cultivation is one of the alternatives that can be done to achieve the business. Therefore the application of technology to society about organic farming on Biopharmaca Cluster of Karanganyar was conducted with the aim to apply organic cultivation techniques that have resulted from previous studies, so it can be applied by the community to increase income and welfare. This application of technology to society activity is held in Sambirejo, Jumantono, Karanganyar. The research was conducted from March to October 2016. The results showed that the application of chicken manure affects the number of leaves, number of tillers, and the fresh weight of turmeric rhizome. The addition of manure (chicken, goat, cow) can increase all variables of planting growth which include plant height, number of leaf, number of tillers, fresh weight of plant, dry weight of plant, and fresh weight of rhizomes. Giving three types of manure (chicken, goat, cow) with mycorrhizal dose treatment there is no intraction to some growth observation variables. Mycorrhizal treatment with a dose of 10 g/plant can increase the number of tillers in turmeric. Overall the application of mycorrhizal at various doses (5, 10, and 15 g/plant) can increase plant height, leaf number, number of tillers, and fresh weight of turmeric rhizome.
