Abstract

The objective of the study was to find out the respons of A. andraeanum and A. wave of love   to various fertilizer formula. The experiment was carried out on April 2007 to April 2008 in the plastic house in Segoro gunung, Karang anyar.  The experiment was arranged in a factorial design, with three replications.  The first factor was species of Anthuriums (A. andraeanum and   A. Wave of love), and the second factor was fertilizer formula.  The fertilizer used were granule slow release fertilizer (chemical fertilizer), green brown liquid fertilizer (organic), light green crystallic fertilizer (chemical), and green liquid fertilizer (organic). Plant height and number of leaves were measured at 6, 8, 10, and 12 months after planting, and flower number, flower stalk length, spathe length, spathe width, and spadix length were measured at 12 month after planting.  The results of the experiment showed that A. andraeanum dan A. Wave of love had different response to the fertilizer formula. Light green crystallic fertilizer, slow release fertilizer, and liquid green brown fertilizer were suitable for the vegetative growth of A. andraeanum, while only light green crystallic fertilizer and slow release fertilizer were proper to the vegetative growth of          A. Wave of love.  The generative growth of A. andraeanum was better in the application of light green crystallic fertilizer, and slow release fertilizer.

Abstract

High content of aluminium and low P availability in Inceptisols are the important limiting factors for crop production. Hence, important efforts on management of Inceptisols are the increasing in  P availability for crop demand. Cacao fruit skin bokashi is a source of organic matter used to improve the soil, although using bokashi  as organic fertilizer is still not yet have full attention.   A study that was aimed to elucidate roles of cacao fruit skin boakshi on Al concentration, and soil    P status in an Inceptisols was conducted in a laboratorium. Five treatments consisting of the rates of the bokashi (10, 20, 30, 40 and 50 ton/ha) and one control (no bokashi added) were arranged in a completely randomized design with three replicates. Results of the experiment showed that the application of 30 t ha-1 cacao fruit skin bokashi significantly increased soil pH, soil organic-C,                  P-total and P availability, and reduced Alexch concentration. However, the soil pH and P availability were reduced at the rate of bokashi of 40 and 50 t ha-1, but Alexch concentration was increased.

Abstract

The study of the efficacy of some bioinsecticides and their combinations to control Pagodiella spp. or bagworm attack on mangrove seedling was carried out in the seedling nursery of Malakosa and Sausu Peore Parigi Moutong, Central of Sulawesi, February to April 2008. A Nested design was applied in a Completely Randomize Design, where three levels of spraying intervals and eleven-application methods with three replications were used. The results showed that the application of microbial insecticides of Bacillus thuringiensis individually was effective in depressing Pagodiella spp. bagworm attacks (increasing of damage level 8,98% and 14,38%, respectively) also combination (increasing of damage level 11,36%). The combination applications among microbial insecticides and botanical insecticides were also effective in depressing Pagodiella spp. bagworm attacks. But both of the combination applications had no synergistic effect. Whereas the combination among botanical insecticides of mimba and sirsak were effective in depressing Pagodiella spp. bagworm attacks, which also produced synergistic effect (increasing of damage level 12,98%).

Abstract

This study aimed to examine the effect of various insecticides against beet armyworm pest (S.exigua) and onion yield. The experiment were conducted in Poso district and arranged using arandomized block design (RBD) with two-factor treatment and tree replicates each. The first factorwas the type of Insecticides (I) consists of three treatments and one control, namely: (1) Noinsecticides (I0), (2) botanical insecticides (neem leaf extract) 50 g/l of water (I1). (3) Biologicalinsecticides, the fungus Beauveria bassiana 10 g/l of water (I2) and (4) chemical insecticides,Klensect 200 EC 1 ml/l of water (I3). The second factor was onion varieties composed of: (1) Bima(V1) and (2) Tinombo (V2) vartieties. Variabel measured included: S.exigua population density,percentage of attacks of S.exigua, and dry weight of tuber. The results showed that insecticidestreatment significantly affected the population density and S.exigua attacks on onion crops in thedistrict of Poso. The effectiveness of chemical and botanical insecticides on suppressing thepopulation density and the attack of S. exigua were nearly similar and significantly higher than thatof biological insecticide. The population density and percentage of S. exigua attacks did not differsignificantly in both varieties but dry weight of tuber was higher in Bima variety. There was nointeraction effect between insecticides and onion variety on population density and attackpercentage of S. exigua as well as on tuber weight.Key words: Insecticides, onion, S. exigua variety, and yield.

Abstract

The research aimed at identifing the respons of various population of sweet corn plant on urea fertilizer application.  The research was carried out in Solowe, Sigi Biromaru sub district, Donggala regency from September to December 2007.  The research used a Randomized Block design in a factorial experiment.  The first factor was urea fertilizer (P) consisted of 200 kg/ha (p1), 300 kg/ha (p2), and 400 kg/ha (p3).  The second factor was plant population (J) included one plant per cluster (j1), two plants per cluster (j2), and three plants per cluster (j3).  There were 9 combinations of treatments with three replicates for each treatment.  Therefore, there were 27 experimental units.  The research results showed that both the urea fertilizer and plant population had significant influence on all parameter observed but tassel flowering.  Whereas the interaction between the two factors was significantly influenced the seed number per cob and cob weight per cluster.  The application of 400 kg/ha urea fertilizer improved the growth quality of sweet corn as shown by larger stem diameter, longer and bigger cob, and kernel number per cluster. Population with one plant per cluster resulted in higher yield.  Increasing plant number per cluster significantly reduced plant yield.  There was interaction effect between plant population and urea fertilizer rate on kernel number per cob and cob weight per cluster.

Abstract

The experiment was conducted to assess the influence of various seed handlings in light and without light.  Positive contribution in science and technology development is to increase effectiveness and efficiency of areca seed germination.  The experiment used a split plot design, with the main plot was light (with and without light) and seed handling as patch (seeds soaked in water for 2, 4, 6 days and seed wetted for 4, 6, 8 days).  Each treatment was replicated three times.  Data were analyzed using analysis of variance and 5% honestly significant difference. Dark condition accelerated areca seed germination (39.44% growth potential, 93.33% germination rate reached 90 days after planting and 63.33 days to germinate) and increased the number of root and shoot dry weight.

Abstract

The research aimed to identify the growth of some papaya varieties as affected by various fertilizer applications. The research was carried out from November 2008 to March 2009 in "Puspita Karya Karava Tandau" Sidondo of Sigi Regency.  The research used a Split Plot Design.  The main plot was various papaya varieties (V): small local (v1), big local (v2), item (v3), watermelon (v4), Mexico (v5), and Bangkok (v6). The sub plot was fertilizer types (P): control (p0), Saputra Nutrient (p1), NPK (p2), bokashi (p3), Saputra nutrients + NPK (p4), and Saputra nutrient + bokashi (p5). The results of research indicated that only the manure types had significant effect on the growth of papaya.  The mixture of saputra nutrient+bokasi resulted in significantly larger plant stem diameter at 16 months after planting (MAP), height at 18 MAP, and dry weight than any other treatments.
