Abstract

Melon (Cucumis melo L. ) is a horticultural crop that is quite popular in Indonesia . Good taste and nutritional content makes melon increasingly popular with the public . However , often the continuity of supply in the market is still limited. This is due partly because farmers in Indonesia are still planting using seeds imported melons which is quite expensive. Therefore, an effort that can be done to reduce dependence on imported seed is seed multiplication through tissue culture techniques . The growth in tissue culture plants  is controlled by the addition of plant growth regulators . This study aims to determine the effect of BAP and casein hydrolyzate  for better shoot growth in vitro melon . This research has been carried out in the Laboratory of Plant Biotechnology , Faculty of Agriculture , University Tadulako , Palu . Starting from August to November 2012 . The study design using completely randomized design ( CRD ) Factorial pattern of two factors . The first factor is the concentration of BAP ( 0.25 mg / l , 0,50 mg / l and 0.75 mg / l ) , the second factor is the concentration of casein hydrolyzate ( 150 mg / l , 200 mg / l and 250 mg / l ) . significant treatment effect , Further tests using the Test Honestly Significant Difference ( HSD ) at the 5% level . The results of this study indicate that the use of media with different compositions lead to different effects on the growth of shoots melons . Treatment of 0.50 mg / l BAP + 150 mg / l casein hydrolyzate gives a better effect on plant height, number of shoots and number of leaves

Abstract

This study aims to identify the morphology and anatomy of mangosteen in Donggala especially in the Village Labean and Batusuya. Collection of material using morphological methods of exploration in the field of mangosteen in the Village and Village Batusuya Labean, while observing the anatomy of mangosteen conducted at the Laboratory of Integrated Pest and Disease Tadulako. The research was conducted from August to October 2015. The total sample of mangosteen were observed for morphology and anatomy is 20 samples consisted of 10 samples from the Village Batusuya and 10 samples from the Village Labean, the collected data were analyzed using cluster analysis and the results are seen in dendogram form. From the results contained dendogram diverse accessions of mangosteen in Donggala, especially in the Village and Village Batusuya Labean. Of the existing diversity obtained by the two groups in the Village Batusuya namely BS1 and BS4. Likewise the two groups for the Village Labean ie LB4 and LB2. And a combination of two villages in the two groups obtained mangis namely BS4 and LB2. Key Words: Anatomy, mangosteen, morphology.

Abstract

The experiment was conducted to determine the composition of bokashi fertilizer and liquid organic fertilizer concentration of goat manure on the growth of mustard. This research has been conducted in the Binangga Village, Marawola Sub. District, Sigi Regency since August to November 2014. The research was arrangedbase on Randomized Block Design (RBD) consisting of three levels: control, bokashi 30 tons / ha, liquid organic fertilizer 5 cc / liter, bokashi 15 tons / ha + POC 5 cc / liter, bokashi 30 tons / ha + POC 2,5 cc / liter, bokashi 15 tons / ha + POC 2,5 cc / liter, bokashi 30 tons / ha + POC 5 cc / liter. Thus, there are 7 treatments was repeated 3 times. Data were analyzed by analysis of variance followed by Honestly Significant Different (HSD), if there is a treatment effect on the growth of mustard. The results showed that giving of bokashi organic fertilizer goat manure waste and waste liquid organic fertilizer manure goat very significant effect on the parameters of plant height, number of leaf, leaf area, fresh weight of crown and root, crown dry weight and root crops and fresh weight the total cropand dry weight the total crop. Bokashi organic fertilizer treatment and the best liquid organic fertilizer on growth is at a dose of 15-30 tonnes / ha + POC 2,5-5cc / liter.
