Branch Cutting

Betung bamboo (Dendrocalamus asper) as multipurpose plant could be developed with vegetative and generative propagation.  Branch cuttings was the easiest way in the betung bamboo vegetative propagation.  One of plant growth regulators that could be used to spur betung bamboo branch cutting was indole butyric acid (IBA).  This study was conducted to evaluate the betung bamboo branch cutting response from various concentration of IBA and to know the best concentration of IBA to spur the growth.  The experiment was conducted in Palembang’s Bamboo Plantation Collection and Development Research Institute of Forest areal, Tanjung Agung, District Tanjungan, South Lampung Regency, from March to June 2012.  This research used Completely Randomized Design (CRD) with five treatments: IBA 0 ppm (control), 100 ppm, 200 ppm, 300 ppm, and 400 ppm of concentration.  Each of experimental unit consisted of five cuttings with five replications.  Percentage of life, length of shoot, number of shoot, number of leave, shoot’s diameter, and root’s length were the observed variables.  The result showed that betung bamboo branch cuttings were responsive to IBA, and IBA 200 ppm concentration gave better results to the betung bamboo branch cuttings than IBA 0 ppm (control), 100 ppm, 300 ppm, and 400 ppm concentration. Based on this study, it was recomended to use 200 ppm of IBA for betung bamboo branch cutting. Keywords : betung bamboo, branch cutting, indole butyric acid

Chrysanthemum is an ornamental flower plant that has advantage because of various colors and has long vase time. The minimum potential for chrysanthemum development in Bangka is because of limited seed and the enviroment conditions in Bangka are less than optimal for chrysanthemum plants. The increasing chrysanthemum seedlings can be done vegetatively by addition of IBA hormone with an ex-vitro system. This study aims to determine the effect of IBA (Indole Butyric Acid) hormone on the growth of chrysanthemum cuttings in Bangka. This research was conducted from March to May 2020 at the Research and experimental Garden, Faculty of Agriculture, Fisheries and Biology, Universitas Bangka Belitung. The research method used an experimental method with a single completely randomized design (CRD) consisting of 6 treatments, namely (Control), IBA 50 ppm, IBA 100 ppm, IBA 150 ppm, IBA 200 ppm, IBA 250 ppm. The results showed that giving IBA had no significant effect on the growth of chrysanthemum cuttings in Bangka. Treatment (IBA 150 ppm) tends to be better for the growth of chrysanthemum cuttings in Bangka.

The use of hormones is important in improving the propagation process. The objective of the experiment was to identify the best dose of indole butyric acid (IBA) hormone for the rooting of coffee cuttings of the typical variety through clonal propagation in the Amazon region. The experiment was carried out in two stages. Both stages were carried out under a Completely Randomized Design (CRD). The percentage of rooting of cuttings and the number of roots were evaluated. The coffee tree clones were collected from rust tolerant elite plants. In the laboratory, the cuttings were immersed for 10 minutes in fungicide and then in five doses of IBA hormone (1000, 1500, 2000, 2500, and 3000 mg L−1) of IBA. They were then placed in a microtunnel. With the best dose obtained in stage 1 of IBA (T4: 2000 mg L−1), which achieved a rooting percentage of 52.50% and 5.8 roots on average, stage 2 was installed for the evaluation of acclimatization conditions (greenhouse and nursery). Thirty plants of the Típica variety were evaluated per treatment. Regarding the results after 90 days, the greenhouse obtained the highest values with 72.22% survival, a plant height of 9.48 cm, 4.32 mm stem diameter, 6.53 leaves per plant, 9.65 cm leaf length, and 3.83 cm leaf width. The IBA hormone in a controlled environment such as the greenhouse achieves good vegetative propagation for the Típica variety.

A New Technique

       The people of Hulu Sungai Utara Regency are very fond of pineapple, this can be seen from the continued increase in market demand for pineapple. Pineapple production in Hulu Sungai Utara Regency from 2010-2013 continues to increase. However, the availability of pineapple is still widely supplied from other regions. This is due to limited land and the availability of superior seeds. Therefore we need a new technique to overcome this problem by multiplying it in vitro. This study aims (i) to determine the response of pineapple plant growth to various concentrations of IBA (Indole Butyric Acid) in vitro and (ii) to obtain the best IBA (Indole Butyric Acid) concentration for pineapple plant growth in vitro. The study was conducted in the Amuntai STIPER tissue culture laboratory from March to June 2014, using a Completely Randomized Design (CRD) with 5 treatment levels, 4 replications. The factor tested was the IBA concentration, i1 = 1.5 ppm, i2 = 2 ppm, i3 = 2.5 ppm, i4 = 3 ppm, and i5 = 3.5 ppm. The results showed no known response and the best concentration of IBA on pineapple plant growth.

The use of halophytes such as Salicornia bigelovii represents an alternative with economic potential for desert agriculture and coastal areas. However, the success in the establishment of commercial plots has been limited by the low germination percentages of this species. Propagation using plant cuttings represents a viable and rapid alternative to this problem. The formation of functional roots is fundamental in the propagation of plant cuttings and has been achieved through the application of chemical growth regulators. The application of chitosan in some crops has evidenced to be an alternative for the germination process and an enhancer of harvest performance; however, there are no studies that evaluate its effect on the halophyte S. bigelovii. The objective of this research was to evaluate the effect of marine-derived chitosan and indole butyric acid as root-promoting agents in cuttings of Salicornia bigelovii. The concentrations (individually and combined) of chitosan at 100 and 50% and indole butyric acid were applied at a rate of 0.937 and 1.25 g kg‑1. A completely randomized design of nine treatments and f ive repetitions was used and 225 experimental units were evaluated. The following variables were measured: root length, fresh weight and total dry weight of the root, and number and length of new shoots. The results showed that the most eff icient treatment was 100% chitosan + 0.937 g kg-1 indole butyric acid, promoting the production of photosynthetic shoots up to 800%. These results indicate that it is feasible to achieve the propagation of Salicornia by means of cuttings using marine-derived chitosan as a growth promoter.

Abstract Piglets experience a decline in body temperature immediately after birth, and both drying and warming piglets at birth reduces this. However, these interventions may have less effective at higher farrowing room temperatures. This study was carried out at a commercial facility to compare the effect of drying and/or warming piglets at birth on postnatal rectal temperature (RT) under relatively warm farrowing room temperatures (26.6 ± 2.09°C). Forty-five sows/litters were used in a completely randomized design to compare three Intervention Treatments (applied at birth): Control (no treatment); Warming (piglets placed in a plastic box under a heat lamp for 30 min); Drying+Warming (piglets dried with desiccant and warmed as above). Temperatures in the warming boxes over the study period averaged 37.7 ± 2.75°C. At birth, piglets were weighed; RT temperature was measured at 0, 10, 20, 30, 45, 60, 120, and 1440 min after birth. Blood samples were collected at 24 h after birth from a subsample of one piglet from each birth weight quartile within each litter to measure plasma immunocrit concentration. Data were analyzed using PROC MIXED of SAS with litter as the experimental unit; and piglet a subsample of litter. The model for analysis of piglet rectal temperature included fixed effects of treatment, measurement time (repeated measure), the interaction, and the random effect of sow. Compared to the Control, piglet RT were higher (P ≤ 0.05) for the Warming treatment between 10 and 60 min, and higher (P ≤ 0.05) for the Drying+Warming treatment between 10 and 120 min after birth. Rectal temperatures were higher (P ≤ 0.05) for the Drying+Warming than the Warming treatment between 20 and 120 min. Responses to drying and/or warming were greater for low birth weight piglets (&lt; 1.0 kg) than heavier littermates, but were generally less than observed in previous experiments with similar treatments carried out under cooler temperatures. Piglet immunocrit values were lower (P ≤ 0.05) for the Drying+Warming treatment compared to the other treatments, which were similar (P &gt; 0.05). Immunocrit values tended (P = 0.10) to be lower for light (&lt; 1.0 kg) compared to heavier birth weight piglets. In conclusion, drying and warming piglets at birth was more effective for reducing piglet RT decline after birth than warming alone, though the effect was less than observed in previous studies carried out under cooler farrowing room temperatures.

Two experiments were carried out to determine the bioavailability of phosphorus in two spray-dried yeasts - sugarcane yeast (SCY), and sugarcane yeast + brewer's yeast (SCBY) - in starting pigs, by comparing different methods (Apparent Digestibility Coefficient of Phosphorus - ADCP; True Digestibility Coefficient of Phosphorus - TDCP; slope ratio; and standard curve). In experiment I, a digestibility assay were carried out using 30 cross breed pig with initial weigh of 22.69 ± 4.24kg, allotted in a completely randomized design. The mean ADCP and TDCP values were 62.68 and 64.15% for SCY and 77.01 and 79.33% for SCBY. ADCP and TDCP for SCBY were higher (P<0.05) than the values for SCY. In Experiment II, a growth test was conducted, 56 crossbred piglets, were utilized, with initial live weight of 15.11 ± 3.43kg, allotted in a completely randomized design, with seven treatments, four replications, and two pigs per experimental unit. The treatments consisted of a basal diet without supplementation with P and the same diet including supplementation with two levels of P (0.053% and 0.105%) from dicalcium phosphate, SCY and SCBY. The relative bioavailability mean value of 57.23% for SCY and 91.96% for SCBY, corresponding to 0.30% and 0.40% of available phosphorus, respectively.

The objective of this work was to evaluate the productive performance of broccoli under different top-dressing organic fertilizations. The experiment was conducted under protected cultivation, in a completely randomized design with four replications, with two plants per experimental unit. Broccoli seedlings were produced in a commercial substrate in styrofoam trays. The seedlings were transplanted to plastic pots containing 10.0 L of substrate made up of subsoil and organic compost at the ratio of 3:1 (v/v), respectively, which is equivalent to about 20.0 t ha-1 of organic compost at planting. After seedling establishment, the top-dressing fertilization treatments were applied: gliricidia biomass associated or not with liquid biofertilizer of cattle manure to the soil and bokashi. Two control treatments were established: one with mineral fertilization recommended for the crop and the other without top-dressing fertilization. The broccoli production was evaluated (commercial standard). Plants that received mineral fertilizer were more productive, however, they were not significantly different (p>0.05), by Dunnet test, from the plants fertilized with 2.5 t ha-1 gliricidiabiomass (dry mass) associated with liquid biofertilizer (2.0 L m-2) applied to soil. Top-dressing fertilizations with only gliricidia, at 2.5 and 5.0 t ha-1 of biomass (dry mass), resulted in no significant increase in production of broccoli inflorescence. The use of bokashi in addition to gliricidia biomass and liquid biofertilizer reduced the efficiency of the fertilization compared with plants that received only gliricidia and liquid biofertilizer.

Two experiments were carried out to determine the nutritional value and to evaluate the performance and carcass traits in the growing-finishing pigs fed on two types of semipurified glycerin, which were made from vegetable oil (SPGV) and mixed of animal + vegetable oil (SPGM). In the digestibility trial (experiment I) 32 crossbreed barrows were used with initial body weight of 45.08 ± 4.11kg. It were used three levels of inclusion (6, 12 e 18%) of semipurified glycerin (SPGV and SPGM) in the basal diet. The metabolizable energy (ME) value of glycerin were estimated by regression of ME (kcal/kg) intake associated with glycerin vs. glycerin intake (kg). The values of ME (kcal/kg) obtained were: 2,731 for SPGV and 2,210 for SPGM. In experiment II, 72 pigs (30.08 ± 1.65 to 60.58 ± 3.57) in growing and (60.83 ± 2.63 to 93.79 ± 5.72) in finishing phase, were allotted in a completely randomized design in a 2 x 4 + 1 factorial scheme, with two types of semipurified glycerin (SPGV and SPGA), four inclusion levels (4; 8; 12 and 16%), eight experimental unit and a control diet containing no glycerin (0%). All pigs were slaughtered to evaluate the carcass traits. The performance results suggest that it is feasible to use up to 16% of both semipurified glycerins on growing and finishing pigs feeding, without impairing performance and carcass traits.

 A research was conducted to increase the virulence of Beauvaria bassiana to the rice bug, L.  acuta, by adding four different substances (materials) to the rice media to grow the fungus. The research was conducted from April to August 2011 at Polinela Laboratory, Bandar Lampung.  To do this a set of experimental unit consisting of five treatments and five replications were arranged in completely randomized design. The  four treatments were media made up of rice (rice based media) each given or added with four different materials such as rice skin powder, corn sugar, grasshopper powder and chitosan powder. The result showed that B. bassiana grown on rice media added with grasshopper powder or rice skin powder were able of causing mortality to the L. acuta as high as 78% and 71%, respectively, meaning that both mortalities were much higher than that of other replication. The virulence values of Beauveria bassiana  grown on those both powder were also higher than that of three others.
