<p>One of the problems encountered in the development of sugarcane (Sacharrum officinarum L.) includes the availability of sugarcane seed both in quality and quantity. Evaluation of bud sett planting method in seed production was required in order to achieve the expected results. The study was conducted at the experiment station Muktiharjo, Central Java in 2012 using PSJT 941 varieties. Treatments applied were the different number of buds on bud sett which were at 3 levels, 1 bud, 2 buds or 3 buds. Research was arranged in a randomized complete block design (RCBD) with 5 replications. Observations were conducted on germination, tillering, plant height, number of stems, number of suckers and number of buds. The data obtained were analyzed with ANOVA and further tested using the Duncan test. Production assessment modeling approach was performed by a regression analysis. Calculation of stem number on 2 buds showed the highest with 9.6 stems/m, 9.2 buds/stem and with the sucker numbers lowest at 0.38 suckers/m. The highest production buds was obtained at planting 2 buds with 847,848.06 buds/ha which can be used as 8.83 ha for the milled sugarcane plantation. Assessment of bud production per hectare could use equation Y = 159655,48.e0,171.X with the independent variable of stem numbers per meter with a correlation coefficient of 0,9007 and a standard error of 1,0699.</p>

This research aimed to determine effects of phytase in cottonseed meal (CM) and rice husk (RH) based diets on true phosphorus digestibility (TPD) by broiler chickens. Two studies were conducted with 576 one-day-old broiler chickens using regression analysis to determine the TPD in these diets and the response to phytase supplementation. Six semi-purified diets were formulated to contain 150 g, 300 g, and 450 g each of CM/kg (experiment 1) and RH/kg (experiment 2) with phytase supplied at 0 and 1000 units/kg. Titanium dioxide was added to the diets at the rate of 5 g/kg as an indigestible maker. A total of 288 broiler chickens in each study were weighed and allotted to the six diets with six replicates of eight birds in a randomized complete block design. The birds were fed the experimental diets until day 26 post hatch. The coefficients of true phosphorus retention (TPR) were 0.8 for CM and 0.78 for RH without phytase; 0.93 for CM and 0.92 for RH with phytase. True phosphorus digestibility was 0.82 for CM and 0.75 for RH without phytase; and 0.95 for CM and 0.92 for RH with phytase. Phytase supplementation resulted in 13.27 and 17.94 % increases in TPD; and 12.29 and 13.61 % increases in TPR by birds fed the CM and RH diets, respectively. Phytase supplementation of CM and RH based diets increased TPD and improved total TPR and true ileal phosphorus digestibility in broiler chickens.

In 1995, the SFA Arboretum initiated a “three Rs”—rescue, research, and reintroduction—endangered plants program, a conservation horticulture strategy that links the Arboretum with the goals of the Texas Parks and Wildlife, U.S. Fish and Wildlife, and other conservation agencies. The program includes two tiers of activity: 1) a 1-acre endangered plants theme garden in the SFA Arboretum for germplasm studies and educating the public, and 2) “introduction” research plots at Mill Creek Gardens, a 119-acre conservation easement 6 miles west of Nacogdoches, Tex. This paper reports on an “introduction” study of one of the most endangered endemics in East Texas, the Neches River rose mallow, Hibiscus dasycalyx. A randomized complete-block design with three blocks and four plants per replication was established in Dec. 1995, in a full-sun wetland planting at Mill Creek Gardens. Two mulching regimes (with and without) and four rates of slow-release 13-13-13 were applied at planting and again in Mar. 1996. Data collected in 1996 and 1997 included number of stems, flowering, and the weight of all aboveground growth harvested after the first frosts in both years. After 2 years, 1) 80% survival across all treatments with losses primarily in the wettest portions of the plots, 2) mulch influences are nonsignificant, and 3) plant response to slow-release fertilizer is significant with medium and high rates favored for “at-planting” application.

In order to evaluate the establishment and biological effectivenessof the predators Phytoseiulus persimilis, Neoseiulus californicus and Chrysoperla carnea on populations of Tetranychus urticae, a trial was established at the farm “La Pola” (with a cumulative precipitation of 445.9 mm), located in the municipality of Roldanillo, Valle del Cauca, Colombia. Anexperiment was performed under field conditions between September 2017 and May 2018 and using the papaya hybrid Tainung-1 between the stages of vegetative growth and fruit filling. Four treatments were established: T1: 12 releases of P. persimilis and N. californicus; T2: 10 releases of C. carnea; T3: treatment with no predator releases (control); and T4: grower’s practice (15 applications of pesticides) in a randomized complete block design with three replicates per treatment. Samples were collected every eight days by measuring the following variables: infestation percentage, number of fruits/plant, population of T. urticae, P. persimilis, N. californicus, and C. carnea/leaf and the diameter of the stem (every 30 d). The largest T. urticae populations were found in T3 and the lowest ones in T4. The populations of immature and adult T. urticae did not show significant differences between T1 and T2 but there were significant differences between T3 and T4. The variables diameter of the stem, number of leaves per plant, percentage of infestation, and number of fruits per plant showed significant differences between treatments. The T1 and T2 were equal to T3. T4 had the highest number of leaves and fruits per plant. The released predators did not control the populations of the mite T. urticae under the conditions of the present experiment.

<em>The estimated value of genotype variability, phenotype variability, environmental variability, and heritability have an important role in breeding activities of tea</em> <em>in order to create the superior varieties. The objective of this study was to investigate the phenotypic performance, genotype and phenotype variation, and heritability value of nine genotypes of tea. The study was conducted at Pemandangan block, Tambi Plantation Unit,  Wonosobo, Central Java, from April 2013 until April 2014. The Randomized Complete Block Design (RBD) with nine treatments and three replications was used in this study. The 9<sup>th</sup> of treatments consisted of 2 genotypes of tea resulting from a cross (GMB 3 and GMB 4), 2 introduced genotypes (TRI 2024 and TRI 2025), and 5 local genotypes resulting from selection (Cin 143, Kiara 8, RB 3, Tambi 1, and Tambi 2). The results showed that the genotype of GMB 3 more higher than other genotypes in pecco length, leaf length, leaf width, length of leaf stalk, and length of leaf internodes characters, whereas Tambi 2, GMB 3, and GMB 4 more higher in fresh weight of P+2 and P+3. The production of fresh shoot of GMB 4 more higher than the other genotypes, but not significant with GMB 3 and RB 3. The leaf length and fresh shoot production characters has a wide of genotype and phenotype variability, whereas the high of heritability value were found in all characters observed. The selection based on leaf length and fresh shoot production characters will be effective because both characters have a high genotypes variability and heritability.</em>

It is believed that silicon (Si) application could increase rice production, however studies related to those topics are still limited. The study determined the combination effect of Si application and water management on rice growth and productivity. This study was conducted at the experimental station of Indonesian Agricultural Environment Research Institute, Jakenan, Pati, Central Java at dry season. A split-plot in randomized complete block design with four replications was set. The main plots were different types of irrigation and subplots were Si fertilizer application. Results showed that the application of Si increased plant resistance on blast disease. This current result might be due to the increasing of Si concentration in leaves. IT water management significantly increased the yield compared to CF. IT increased root growth and gave an impact on increasing of plant growth and rice yield. Moreover, IT significantly increased Cu, Mn, and Zn concentration in rice grain. Combination of Si application with IT water management could increase rice plant productivity especially in area with water shortage.

The effect of shade covers on degradation of insecticide, carbaryl on field-grown pakchoi (Brassica rapa subsp. chinensis) was examined by a commercial enzyme-linked immunosorbent assay (ELISA) kit. Carbaryl at a.i. 10.6 g·L-1 (1.42 oz/gal) was applied to the plants grown under five different shade treatments including control without any coverings. The experiment was arranged in a randomized complete block design with three replications. Pesticide residue on leaf tissues was examined on dates of 1, 3, 5, and 7 days after pesticide application. On all sampling dates, pesticide residue was greater with treatments with higher shade percentage. Both linear and quadratic relationship of shade (independent variable) and the concentration of remained carbaryl (dependent variable) were significant (P < 0.05). The half-life of carbaryl on pakchoi leaves ranged from 2 days for control to 9 days for the heaviest shade (75%) treatment with rain protection.
