Soybean as a protein sources can fill the needs of public’s food increasily but the production in this country is still low. Therefore, cultivation efforts are needed to improve the growth and development of soybean plants. Some factors that are sufficient to influence the plant growth process are nutrient supply, water availability, sunlight, air temperature, oxygen and growth regulators. Plant Growth Regulator (PGR) that can be used is moringa leaves as a source of cytokinins. Cytokinin serves stimulating cell division, postpone the process of aging plants, and spur growth budding. This study aims to determine the effect of giving plant growth organic made by moringa leaves with 2 control, which are negative control (0%) and positive control (cytokinin synthetic solution) and 3 treatment at concentration of P1 (10%), P2 (20%), P3 (30%) to increase the growth soy plants and to know the concentration optimally of any treatment given. This research using the completely randomized design (CRD) with 5 treatment and 5 replicate. The results were analyzed using the ANOVA test followed by the LSD/BNT test and the Duncan test. The results showed that the application of organic PGR made from Moringa leaves had a significant effect (P <0.05) on growth (plant height and number of leaves) and chlorophyll content in soybean plants had optimal concentrations at 30% concentration.     Keywords: moringa leaves, cytokinin, soybean plants, plant growth regulator.

Prohexadione Calcium

ABSTRACT: This study has aimed to evaluate the effect of prohexadione-calcium as a plant growth regulator on growth and quality of Japanese lawn grass, Broadleaf carpet grass and Bermudagrass. The treatments and doses of the prohexadione-calcium tested with two three reapplications were 27.5, 55.0, 110.0, 165.0 and 165.0 g a.i. ha-1, and a control without application of a growth regulator. Visual injury evaluations were performed using a scale of scores and plant height and chipping dry matter were determined. We have evaluated the total thickness of the sod grass, root length and dry matter of this material at the end of the experimental period. The study was arranged in a completely randomized design with four replications. The results were submitted to analysis of variance by F-test and the averages of the treatments were compared by t test at 5% probability. The prohexadione-calcium plant growth regulator was visually selective and reduced shoot growth of the three species of grass and can thus be used in the management of lawns in gardens and sports areas. As for the production of sod grass, the prohexadione-calcium can be recommended for Japanese lawn grass and Broadleaf sod grass, especially doses 165.0+165.0 and 55.0+55.0+55.0 respectively, because they have provided a better quality sod grass. For Bermudagrass, the effect of the treatments was harmful for the quality of sod grass and is not recommended for production purposes.

Moler disease is the primary disease that disturbs the shallot’ cultivation. Hence, it is beneficial to have preventive measures to mitigate the risk and to improve growth. The research objective is to know the effectivity of Trichoderma harzianum suspension as a bio-fungicide and bio-stimulator. The study used seven treatments, i.e., immersion of shallot seeds on negative control (distilled water), positive control (synthetic fungicide+ZPT 1g/liter), T.harzianum suspension with different concentrations of 2 ppm, 4 ppm, 6 ppm, 8 ppm, and 10 ppm, assigned in a Completely Randomized Design (CRD). Treatment that results in a significant level will be continued to the Least Significance Different (LSD) 5% test. The observed variables are the intensity of moler disease and the growth of shallot seeds. Experiment results show the significant difference between treatments. The optimal treatment to reduce the percentage of moler disease intensity is the immersion of shallot seeds in 10 ppm-concentrated T.harzianum suspension, while to improve the shallot growth is in 8 ppm-concentrated T.harzianum suspension. The intensity of moler disease has a negative correlation to the plant’s height and leaf’s diameter but shows no correlation pattern to the number of leaves, wet weight, dry weight, and length of roots.

Vanda tricolor Lindl. Var. Suavis forma Bali has a specific character than the forma Merapi and forma West Java that is size of flowers and fruits, spots purple in labellum purple colored labelum and floral fragrance. High genetic diversity is one of the major factors in breeding improvement. Increasing the diversity of orchid plant characteristics can be done by giving paclobutrazol. Treatment by paklobutrazol in culture medium aims to inhibit growth both in number of leaves and shoot length so that the plant becomes smaller size than their parent or original. The result of growth resistance that occurs varies based on the concentration of paclobutrazol added to medium Vacint & Went (VW) in culture of seeds V. tricolor orchid added with coconut water with concentration of paklobutrazol Control K0 (0%), K1 (1mg / l), K2 (3mg / l), K3 (5mg / L), and K4 (7mg / l). Each treatment performed 5 times repetition. The result of planting of Vanda tricolor seed explants with paclobutrazol modification in vitro was found 40% cultured imbibition and then protocorm, 8% browning on seed, and 52% contamination. This study showed descriptively the orchid seed Vanda tricolor responded to Vacint and Went (VW) media which was added with plant growth regulator of paklobutrazol, so that it was able to grow and develop until reaching phase 1 that seeds to form protocorm, but statistically the addition of plant growth regulator of paklobutrazol has not show a significant influence on the growth and growth response of orchids Vanda tricolor (P> 0.05) because the observation time is not sufficient for at least 6 months of observation and see the function of paklobutrazol is to slow the growth.

An environmentally friendly agricultural system with organic fertilizer is used to reduce the use of chemical fertilizers, thus producing healthy agricultural products for consumption. Liquid organic fertilizer from bamboo shoots is an alternative substitute for chemical fertilizers in the planting of cayenne pepper (Capsicum frustescens L.) hydroponically. This study aims to determine the effect of bamboo shoot liquid organic fertilizer on hydroponic cayenne pepper pre-antithesis growth. The study was conducted at the Biology Laboratory of UIN Raden Intan Lampung, using a Completely Randomized Design (CRD) with 6 treatments with 3 replications. The treatments included negative control (water), positive control (AB mix), P1 = 10%, P2 = 15%, P3 = 20%, P4 = 25% ml. The parameters include plant height, number of leaves, stem diameter, plant fresh weight. Data were analyzed using One Way Anova (SPSS 17.0), followed by LSD at the 5% level. The results show the effect of treatment on all parameters. Control positive (AB mix) gave the best results on all parameters, then successively treated P4, P3, P2, P1, K0 (negative control). Although not as good as using an AB mix solution, the administration of bamboo shoots POC with a concentration of 25% can support the growth of hydroponic cayenne pre-synthesis.

The formation of nitrogen-fixing root nodules, plant mass and soybean yield under the use of post-emergence herbicides and their combinations with plant growth regulator Athonic Plus and mіcrofertilizer Nanomix was studied. It was established that application of tank mixtures of post-emergence herbicides had led to the reduction of number and mass of nitrogenfixing nodules on the roots of soybean plants. Application of the Athonic Plus and Nanomix preparations, on the contrary, had promoted studied indices. The maximum soybean yield was observed in the variants with tank mixtures of herbicides Nabob + Fabіan + Mіura and Nabob + Fusillade Forte 150 EC. Combination of Athonic Plus and Nanomix preparations with post-emergence herbicides had resulted in the reduction of the herbicides efficiency against weeds, which had prevented to unleash high yield potential of the crop.

<em>Robusta coffee </em>(Coffea canephora)<em> is a cross-pollinated plant, therefore vegetative propagation is necessary to ensure identical traits with parents, such as tissue culture techniques through somatic embryo. The study aimed to find the effect of plant growth regulator 2.4-D and thidiazuron in inducing embryogenic callus, by adding incision area on leaf explant, and to evaluate addition of GA<sub>3</sub> in increasing somatic embryo conversion. The study was conducted from December 2014 to June 2016 in the Tissue Culture Laboratory, IAARD, Bogor. The research consisted of 2 stages. Stage 1 used a complete randomized design of 2 factors; the first factor was a combination of plant growth regulator 2.4-D (1.0 and 2.0 mg/l) and thidiazuron (1.0; 3.0; and 5.0 mg/l), the second factor was leaf incision (slashed and unslashed). Stage 2 used a complete randomized design, with GA<sub>3 </sub>treatment at different concentrations (0.0; 0.5; and 1.0 mg/l). Observed variables were percentage of callus formation, fresh weight of callus, number of torpedoes, number of somatic embryos at cotyledon stage, and number of germinated embryo. The results showed growth regulatory treatments influenced the percentage of embryogenic callus formation and fresh weight of callus. Extra incision on leaf showed no effect in  embryogenic callus induction. Embryogenic callus inducted using 2.4-D 1.0 mg/l + thidiazuron 5.0 mg/l medium which  then regenerated in ½ MS medium added with kinetin 2 mg/l exhibited  the highest number of germination.  Adding GA<sub>3</sub> 0.1 mg/l in regeneration medium is recommended to increase somatic embryos of Robusta coffee BP 308 clone.</em>
