Pepper (Piper nigrum L.) is one of the spice plants that have high export value and propagated by cuttings. Use of internodes number and growth regulator were needed as a way to provide a good of planting material through cuttings. This research aimed to determine the best interaction between internodes number and concentration of Rootone-F growth regulator on growth of pepper (Piper nigrum L.) by cuttings. This research was carried out in experimental garden of Agriculture Universitas Pembangunan Nasional “Veteran” Yogyakarta, Ngemplak, Sleman, Yogyakarta, since February – May 2019. This research used a Randomized Block Design (RBD) with two factors. The first factor was internodes number which were one, two and three internodes. The second factor was concentration of Rootone-F which were 50 ppm, 100 ppm, and 150 ppm. So there were 3 x 3 = 9 treatments combination. Cuttings wit seven intenodes without Rootone-F were used as control. The result showed there were no interaction from two treatments in each parameter. There were no significant difference between control and treatment of each parameter. Internodes number has significantly affected in paramater percentage of life, day of emergence shoot, shoot length, number of leaves, number of root, root volume and shoot dry weight with the best result were cutting with 3 internodes. Concentration of Rootone-F has significantly affected in parameter percentage of life and day of emergence shoot, concentration 100 ppm and 150 ppm better than 50 ppm.Keyword: Pepper plant, cuttings, internodes, Rootone-F.

The study’s objective was to determine the effect of the NO3-: NH4+ratio and types of support on NPK uptake and pepper plant growth in field conditions. The study used a completely randomized block design with three replications. The first factor was the type of support, being the deadwood and living supports in the form of Gliricidia sp. and Ceiba pentandra. The second factor was the ratio of N fertilizer forms, which were 100% NO3-, 100% NH4+, 50% NO3-:50% NH4+, 75% NO3-:25% NH4+ and 25% NO3-:75% NH4+. The results have demonstrated that the uptake of N, P, and K, as well as the plant growth, were not affected by the interaction of the N fertilizer form ratio with the types of support. In field conditions, the black pepper prefers the N fertilizer in the form of 50% NO3-:50% NH4+. The pepper plants that were given N fertilizer in a combination of 50% NO3-:50% NH4+ have demonstrated an N, P, and K uptake, and morphology and plant dry weight were higher than the ratio of other forms of N fertilizers.

Kalapi (Kalappia celebica Kosterm.) is endemic in Sulawesi and Endangered species. Plant propagation needs to be done but is constrained by limited seeds. Vegetative propagation of plants can be an alternative method such as using the root cutting technique that has been done previously on other types of species. This study aims to determine the success of vegetative propagation of kalapi (K. celebica), an endangered tree species by root cuttings using Rootone F. as root growth regulator. The research took place from March to June 2019 conducted at the plastic house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch, Kendari. This study used a Randomized Block Design (RBD) consisting of 6 treatments of Rootone-F concentration : (a) 0 ppm, (b) 100 ppm, (c) 200 ppm, (d) 300 ppm, (e) 400 ppm and (f) 500 ppm. Each treatment was repeated three times and three units of the plant so that the total experimental unit used was 54 units. The results showed that the provision of Rootone-F could increase the success of the growth of kalapi root cuttings. Rootone-F concentration of 500 ppm gives the best results on the percentage of cuttings, percentage of sprouts, percentage of roots, number of shoots and shoot dry weight. The results showed that kalapi can be propagated by root cuttings.

Temperature is a primary factor that affects the rate of plant development and has great impacts on plant growth, metabolism, and yield. A study was conducted to analyze the effects of elevated temperature on rice morphological and the physiological growth. The research was arranged in a nested randomized block design consisting of two factors, temperatures and rice varieties. Elevated temperatures were provided through the uses of different materials of plastic roof and walls to have an average and maximum temperature of 27.6 °C and 41.6 °C (T1); 28.1°C and 43.8 °C (T2), and 29.5°C and 47.1 C (T3), respectively. The study used three varieties of rice, “Ciasem”, “Ciherang”, and “IR64”. All rice varieties showed signifi cant increases in tiller number per hill and shoot dry weight, but had a decrease in the stomatal conductance, transpiration rate, and SPAD values at grain fi lling stage with the increasing temperatures. The number of tiller per hill increased when temperature was elevated from 27.6 to 28.1 and 29.5°C by about 29.9 and 21.3%, respectively.

Rice is a rice-producing food crop which now plays an important role in economic life in Indonesia. Namely rice as a staple food is very difficult to replace by other staples. Among them are corn, tubers, sago and other carbohydrate sources. So that the existence of rice is now a top priority for the community in meeting the needs of carbohydrate intake that can be filling and is a source of primary carbohydrates that are easily replaced into an energy source. Rice as a staple food is consumed by approximately 90% of the total population in Indonesia for daily essential food (Saragih,2001). How to plant with the jajar legowo system has the advantage that the plants are on the edge so that optimal sunshine can cause plant productivity to be high, facilitate weed control and pests / diseases, use of fertilizer more effectively and the availability of empty space for regulating water channel circulation on land (Sirrapa, 2011). This research was conducted using Factorial Randomized Block Design (RBD) method, which consisted of two factors and each factor consisting of 3 levels repeated 3 times, namely: J1: Conventional,J2: Jajar Legowo 2: 1,J3: Jajar Legowo 4: 1. Factor II: Varieties with 3 levels, V1: Situ Bagendit, V2: Ciherang,V3: IR-64. Of the two factors 9 combinations of treatments were obtained and repeated 3 times. Data obtained from observations were calculated by analysis of variance with the Fisher test (-F test at the level of 5% and 1%), if there were significant differences, it would be followed by the Smallest Significant Difference test (LSD 5%). The treatment of the legowo 4: 1 row system and the ciherang variety (V2J3) produces a better value than other treatments.

Twenty genotypes of chickpea were evaluated to study the interaction of chickpea genotypes, mesorhizobial strains and vesicular arbuscular mycorrhiza for 14 nitrogen fixing and yield attributing traits viz. days to 50% flowering, days to maturity, plant height (cm), number of branches per plant, number of pods per plant, 100 seed weight (g), seed yield per plant (g), number of nodules per plant, nodule weight per plant (g), root dry weight per plant (g), shoot dry weight per plant (g), nitrogen content in shoot (%), nitrogen content in grain (%) and VAM infection(%). The analysis of variance revealed the existence of significant amount of genetic variability in the material for all the traits. All the genotypes were treated with three treatments separately (Mesorhizobium sp. Strain CH 1233 (S1); Mesorhizobium sp. Strain CH 810 (S2); vesicular arbuscular mycorrhiza (VAM) (Glomus fasiculatum) and one set was used as uninoculated control. These were grown separately following randomized block design with three replications in each treatment. Comparative analysis indicated the differences between the treatments and behaviour of the genotypes in different environments. In general S1 and VAM showed beneficial interaction for maximum number of traits for all the genotypes. The effect of VAM was the most apparent among treatments. On overall basis, genotypes viz. HC 3, HC 5, GL 94022, ICC 5003LN, HK 2, GNG 663 and BG 362 were observed to be better performing and responsive to bio inoculants having one or more superior traits. These genotypes performing better for specific traits can be used as parents in hybridization programme for improvement of that particular trait.

Response of Salak Seedlings (Salacca Zallaca) Growth to Dosage of Endomycorrhizal Spore in Quartz Sand and Zeolite Carrier Media. This study aimed to study the effect of endomycorrhizal spore dosage and carrier media that were applied directly to the roots of salak plants. The research designed as factorisl by using Randomized Block Design with 2 treatment factors. The first factor was number of endomycorrhiza spores consists of 4 levels i.e 0, 75, 150, and 225 spores per 500 g carrier media per polybag, while the second factor was the type of carrier media consist of 2 levels i.e zeolite and quartz sand. The results showed that interaction between endomycorrhizal spore dosage with   carrier   media   did   not   significantly   influence   the   growth   of   salak   seedlings. Endomycorrhizal spores in doses of 75, 150 and 225 spores per polybag increased root infection and leaf P nutrient content compared to control, but seed height, leaf area, shoot dry weight, root dry weight and total dry weight of seedlings not significantly difference. The zeolite carrier media caused root infection by mycorrhizal was higher than quartz sand media, but the P nutrient uptake and seedling growth were not significantly different. Based on the results of this study it is necessary to make a longer observation of the effect of endomycorrhizal spore doses and carrier media on the growth of salak seedlings.

Background: Problems shallot cultivation in tropical regions such as Indonesia, is low productivity. Planting material is one of the causes of low productivity. The planting material used is a bulb that has been used continuously. It is makes planting material susceptible to infectious diseases and viruses. Efforts can be made to reducing the attack of virus infections in the planting material of the bulbs is by using seeds. However, seed production in Indonesia is still low due to the difficulty of flowering and low viability of seeds. The aim of this research was to detect flowering ability from the source of bulbs flowering and non-flowering clumps using Hd3a primers and endogenous GA3, also the effect of age of bulbs to flowering of shallot. Methods: The study used a complete randomized block design. The treatment consisted of two factors with three replications. The first factor was source of bulbs flowering and non-flowering clumps. The second factor was age bulbs which consists of three levels, namely the 60, 80 and 90 days age bulbs. The contents of gibberellins was analyzed using HPLC analysis. Molecular analysis to determine the potential of flowering genes used SSR primer (Hd3a). Result: Hd3a primer can be used as a marker of flowering shallot. Source of bulbs flowering and non-flowering clumps have the same flowering potential gene. The percentage of flowering in flowering clumps was higher than non-flowering clumps and correlates with endogenous gibberellins content. The age of bulbs indicates that older bulbs gave a higher percentage of flowering.
