Abstract

The Effect of Number of Seeds and Organic Fertilizer on the Growth and Yield of Rice (Oryza sativa L.) This research aims to determine the effect of the number of seedling and organic fertilizers solid and liquid on the growth and yield of rice plants. The research was conducted on March 18 - July 3 2016 at the Greenhouse Garden Experiments Faculty of Agriculture, University of Udayana, Denpasar. The research method is a pattern of split plot using randomized block design consists of two factors: the main plot (organic fertilizer) and subplot (use the number of seeds). The main plot consisted of two levels are solid organic fertilizer and liquid organic fertilizer. Subplot consisted of three levels and 1 , 3, and 5 seedlings per hole. The data were analyzed using analysis of variance with Costat program. Results of statistical analysis showed that one interaction between the use of the number of seedling and organic fertilizers no real effect on the variables tested. The number of seedling treatment use did not significantly affect to the growth and yield, except the total number of tillers. Treatment of solid organic fertilizer is better than liquid organic fertilizer on the growth and yield of rice. Dry grain yield per harvested and oven dried clumps on the use of solid organic fertilizer is higher, at 22,69 g and 14,85 g, compared to using liquid organic fertilizer 15,11 g and 8,19 g. Associated with the use of the number of seeds is recommended to use the number of seeds one per hole, but for the implementation in the field required further research.

Abstract

Efficacy of 18 g / l Abamectin Insecticide Against Species Diversity, Population Abundance of leafhoppers and Harvesting on Paddy Paddy Crops (Oryza sativa L.) This research was carried out in Buwit Village, Kediri District, Tabanan Regency, starting in September to November 2017. The research objective was to determine the effect of Abamectin insecticide 18 g/l on species diversity, population abundance and yield. This study used a randomized block design (RBD) with 5 replications and 5 treatments (control, 0.50g / l; 1.00g / l; 1.50g / l; 2.00g / l). The results showed that leaf leafhopper species diversity was low, as evidenced by the Shanon diversity index value was <1.5. The low value of species diversity index is caused by the low number of species in each treatment. Relatively higher variation in control compared to treatment. Abundance The highest population of nymphs and leaf leafhoppers was seen at 49 days after planting as much as 8.57. Components of harvest also show a significant difference between control and treatment.

Abstract

ABSTRACT Vesicular Arbucular Mycorrhizae (VAM) Identification of Sweet Potato (Ipomoea batatas L.) and Cassava (Manihot esculenta Crantz) Rhizosphere and Its Spore Multiplication in Zeolite Media Vesicular arbuscular mycorrhizae is an obligate symbiont that live in a symbiotic mutualism with plant roots and grow inside root cortical cells helping absorption of nutrients which necessary for plant growth. This research aimed to determine VAM species in sweet potato and cassava rhizosphere and also to determine effectiveness of zeolite media as a multiplication medium. The research has been conducted from October 2014 through December 2014. Spore isolation was done by conducting wet sieving method. Roots colonization percentages were calculated with gridline section method and spores multiplication through trapping culture method. Results showed that there were four VAM genera consist of 16 species from rhizosphere of both sample plants. Those four genera identified as Acaulospora (2 species), Gigaspora (1 species), Glomus (1 species), and Scutellospora (1 species) from rhizosphere of sweet potato and 3 genera identified as Acaulospora (3 species), Gigaspora (3 species), and Glomus (5 species) from rhizosphere of cassava. Colonization is characterized by special structure of VAM such as arbucule and vesicule in plant roots tissue. Inner spores of VAM were discovered in all three kind of plants used in this research. Spore multiplication with trapping culture method using zeolite media and corn as a symbionts can be considered as an effective method for VAM spore multiplication indicated by density increase of VAM spores.
