Arachis pintoy can be reproduced in generative but also vegetative way, for example through cuttage. Problems arising from this reproduction method is the difficulty to form roots. The success rate of this method depends significantly on the size of the formed callus. To analyze the content of nutrients contained in the cuttage stem, we have to cut off the stem. And then it’s necessary to find out additional factors that can influence the forming of the callus with a large percentage of rooting. One alternative solution is the provision of coconut water which believed to contain a variety of nutrients and growth substances. Therefore, we conducted a study to find out the interaction of these two factors on the growth of Arachis pintoy The purpose and goal of this research is to study and identify the growth Arachis pintoy which treated with coconut water its influences on the stem length. This research has been performed in Agrostology Lab of Animal Husbandrys Faculty of Sam Ratulangi University, during a period of 60 days. The research materials consists of Arachis pintoy, Coconut Water and soil. While the research method use 2 experimental factors: Factor A is the Coconut water, Factor B is the after-cuttage-stem length of Arachis pintoy, which arranged through completely randomized design (CRD). Each factor consists of 3 treatments, which repeated 3 times. These factors are as follows: A = volume of Coconut water, A1 = 100 ml of coconut water, A2 = 200 ml of coconut water, and A3 = 300 ml of coconut water. Factor B = stem length of Arachis pintoy, B1 = 10 cm, B2 = 15 cm, and B3 = 20 cm. And the variables which measured in this study were plant height, dry weight of roots and the roots volume. The results showed that administration of coconut water and the length of the cuttings as well as the interaction of two factors give significant effect (P < 0.05) to the growth of the number of leaves and root dry weight of the Arachis pintoy . Furthermore, coconut water does not give effect to the root volume and a combination of two factors do not impact on the growth of plant height. From the data analysis and discussion for all variables in this study , we can conclude that the best combination of growth in the number of leaves , dry weight of roots and root volume is the provision of 300 ml of coconut water and 10 cm stem length. Keywords: Arachis pintoy, coconut water and stem length

PGPR (Plant Growth Promoting Rhizobacteria) is a substance that helps plant growth with the help of rhizosphere microorganisms. PGPR propagation can be done with liquid media. This PGPR propagation needs to be done because this substance has many benefits for agricultural cultivation. The application of PGPR to the test plant, namely the pakcoy plant, proved that there was an effect of giving PGPR to the plant. Observations on the test plants were carried out by observing several observation variables such as plant height, root length, number of leaves, wet weight and dry weight. The results of these observations showed that the effect on the test plants was seen in the variables of root length, wet weight, and dry weight. Meanwhile, the variable plant height and number of leaves did not show a visible difference.

Our objective was to investigate the influence of alternative substrates based on stem decomposed by babassu and humic substances in the production of sunflower seedlings. The experimental design was randomized blocks, in a 3 x 4 factorial scheme (substrate x humic substances). Twelve treatments were studied, T1 (100% babassu stem decomposed (BDS) + 0 ml L-1 HS), T2 (100% BDS + 12.5 ml L-1 HS), T3 (100% BDS + 25 ml L-1 HS), T4 (100% DBS + 50 ml L-1 HS), T5 (50% DBS + 50% LAd + 0 ml L-1 HS), T6 (50% DBS + 50% LAd + 12, 5 ml L-1 HS), T7 (50% DBS + 50% LAd + 25 ml L-1 HS), T8 (50% DBS + 50% LAd + 50 ml L-1 HS), T9 (100% LAd + 0 ml L-1 HS), T10 (100% LAd + 12.5 ml L-1 HS), T11 (100% LAd + 25 ml L-1 HS) and T12 (100% LAd + 50 ml L-1 HS). Each treatment was performed in four replications with one seedling per plot, totaling 48 plots. The DBSxHS interaction provided increases in root length, root volume, basal diameter, number of leaves, plant height and parameters related to inflorescence. The substrate with 100% decomposed babassu stem, together with the dose of 12.5% humic substance, is the best option for producing 'IAC Uruguay' sunflower seedlings. Further research on the use of DBS and HS is needed to address the use and purpose in producing new crops.

The research on adaptation selection for utilization in phytoremediation of soil contaminated by crude oil using four type plants, such as Helianthus annuus, Paspalum conjugatum, Sorghum bicolor, and Tagetes erecta were conducted. The adaptability of four types of plants  on crude oil contaminated soil at total petroleum hydrocarbon (TPH) level at 0, 3, and 6% were observed and evaluated to their morphological and anatomical responses. Parameters observed were vegetative growth of plants including growth precentage, plant height, number of leaves, root length, root dry weight, shoot dry weight, root/shoot ratio, total dry weight, and stomatal density for 9 weeks cultivation in screen house. The results show that increasing in TPH level caused in significant reductions on morphological of four plants, such as percentage of plant growth, plant height, number of leaves, root length, root dry weight, shoot dry weight, and total dry weight. In contrast, the increasing in TPH level caused to increasing in root/shoot ratio. The four types of plants studied were effective to be used as plants for phytoremediation of petroleum contaminated soil. The plants of P. conjugatum and S. bicolor are recommended as phytoremediators for further studies.

Penelitian ini bertujuan yang menguji Perbandingan pertumbuhan vegetatif tanaman cabai merah (capsicum Annuum L.) akibat Pemberian Komposisi PGPR (Plant Growth-Promoting Rhizobacteria) yang perbeda. Pertumbuhan tanaman diukur berdasarkan tinggi tanaman, jumlah daun, volume akar, berat basah dan berat kering tanaman. Hasil penelitian menujukkan bahwa PGPR dapat meningkatkan tinggi tanaman, jumlah daun, volume akar, berat basah dan berat kering tanaman cabe.Tinggi tanaman terbaik setelah diperlakuan selama 28 hari adalah dengan pemberian PGPR disertai dengan pemberian pupuk kandang dengan tinggi (24.44 cm), yang diikuti oleh pemberian PGPR + kompos dengan tinggi (22.04 cm), dan pemberian PGPR + NPK dengan tnggi tanaman 19.68 cm . Volume akar akan lebih tinggi bila diberikan PGPR yang ditambah dengan pupuk kandang , atau kompos maupun NPK, tetapi tdak berbeda hasilnya bila hanya diberikan PGPR saja. Jumlah daun dapat ditingkatkan bila diberikan PGPR yang ditambah dengan pupuk kandang, atau kompos maupun NPK. Pemberian PGPR + NPK tidak memberikan jumlah daun yang berbeda dengan pemberian PGPR saja.Berat basah akan meningkat bila diberikan PGPR saja maupun ditambah dengan pemberian pupuk kandang, atau kompos maupun NPK. PGPR ditambah dengan pupuk kandang maupun kompos memberikan dampak yang sama terhadap berat basah.Berat kering akan meningkat bila diberikan PGPR saja maupun ditambah dengan pemberian pupuk kandang, atau kompos maupun NPK. PGPR ditambah dengan pupuk kandang maupun kompos memberikan dampak yang sama terhadap berat basahThis study aimed to examine the comparison of vegetative growth of red chili (capsicum Annuum L.) due to the administration of different PGPR (Plant Growth-Promoting Rhizobacteria) Composition. Plant growth was measured based on plant height, number of leaves, root volume, wet weight and dry weight of the plant. The results showed that PGPR can increase plant height, number of leaves, root volume, wet weight and dry weight of chilli plants. The best plant height after being treated for 28 days is by giving PGPR accompanied by administering manure with height (24.44 cm), followed by by giving PGPR + compost with a height (22.04 cm), and giving PGPR + NPK with a plant height of 19.68 cm. Root volume will be higher if given PGPR added with manure, or compost or NPK, but the results are not different if only given PGPR. The number of leaves can be increased if given PGPR added with manure, or compost or NPK. Provision of PGPR + NPK does not provide a number of leaves that are different from the administration of PGPR alone. Wet weight increased when given PGPR alone or added with manure, or compost or NPK. PGPR added with manure or compost gives the same effect on wet weight. Dry weight will increase if given PGPR alone or added with manure, or compost or NPK. PGPR coupled with manure or compost has the same effect on wet weight
