Abstract

The availability of high rate of transplanting succes is very important for early growth of snakefruit. An experiment aimed to identify both optimal concentration and frequency of foliar fertilizer application on growthof snakefruit during nursery. The experiment was conducted in Pondok Kelapa, Bengkulu Tengah, from August to October 2008. Concentration and frequency treatments were arranged in a Split Plot base on a Randomized Complete Block Design. Spraying frequency (weekly, two-weekly or three-weekly) were used as the main plot;whereas, concentration of liquid nutrient Hyponex Merah with composition of 25:5:20-N:P:K, consisted of 0, 2, 4 and 6 g L-1 water, was the sub-plot Results demonstrated that concentration of liquid nutrient significantlyaffected seedling growth with optimum concentration for plant height was 4.6 g L-1, the greatest leaf number was 39 g L-1, the largest leaf area was 4.1 g L-1, the greatest stomata number was 4.2 g L-1, the greatest chlorophyl content was 3.9 g L-1 and seedling dry weight was 4.6 g L-1. Both frequency and its combination with concentration of foliar fertilizer had no significant effects on the growth snake fruit seedlings

Abstract

Salinity stress causing water deficit, nutrient deficiency, and ion imbalance for the crops has been reported to reduced crop growth, crop yield, and fruit quality in tomatoes. The main objective of this research were to determine the LC-50 of salinity, to evalute the response of six tomato genotypes to LC-50, and to study the effect of genotype and salinity stress on crop growth, crop yield, and fruit quality of tomatoes. The LC-50 of salinity was determinated by growing tomato seedlings at different level of saline solutions (0, 400, 500, 6000, 7000, 9000, 10000, 11000, and 12000 ppm of NaCl) and used the LC-50 of salinity to evaluate the salinity tolerance of six tomato genotypes. The results showed that the LC-50 of saline solution was 9000 ppm NaCl and genotype Empat G was found to be the most tolerant to salinity stress

Abstract

Pineapple plants are usually propagated vegetatively by utilizing the base of the fruit (ratoone), stem buds (sucker), fruit buds (slip) and crown (crown). Propagation of plants by utilizing parts of the plant is less effective in meeting the needs because the planting material produced is small and requires a long time. An alternative to the propagation of pineapple to increase the amount of planting material is by tissue culture techniques. This study aims to obtain the best types of complex organic compounds and the right concentration for the growth of pineapple shoots in vitro. The research was conducted in June 2017 until October 2017 at the Laboratory of Agronomy at the Faculty of Agriculture, University of Bengkulu. Complete randomized design with 3 replications was used to allocate 9 treatments of complex organic compounds. The basic media used are the composition of Murashige and Skoog (MS). Treatment consists of 1) Coconut water 100 ml / l, 2) Coconut water 150 ml / l, 3) Coconut water 200 ml / l, 4) Banana porridge 100 gl / l, 5) Banana pulp 150 g / l, 6) Banana slurry 200 g / l, 7) Bean sprout extract 100 g / l, 8) Bean sprout extract 150 g / l, 9) Bean sprout extract 200 g / l. The results showed that at 16 weeks after MS media planting the addition of 100 g / l banana pulp was able to produce the highest plant height with an average of 3.45 cm. MS media with the addition of 200 ml coconut water resulted in the highest shoot height of 1.5 cm and followed by MS with the addition of 100 g / l media of banana pulp with an average of 0.9 cm. MS media with the addition of 100 ml / l of coconut water is suitable for the growth of pineapple roots with the average value of the number of roots and the highest length of roots. MS media with the addition of bean sprout extract with various concentrations is not able to stimulate shoot growth and has a growth response that tends to be slow. Keywords: Pineapple, In Vitro, Complex Organic Compounds.
