Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh berbagai dosis pupuk organik mikroba rumpun bambu terhadap pertumbuhan tanaman cabai kriting(Capsicum annuum). Penelitian dilaksanakan disekitar area kampusUntad, Palu. Sulawesi Tengah dan dilaksanakan di Laboratorium Hama dan Penyakit Tumbuhan, dari bulan April - Juli 2013, Penelitian dilaksanakan dalam bentuk percobaan yang disusun berdasarkan rancangan acak kelompok (RAK) yang terdiri dari enam perlakuan dengan dosis pemberian pupuk organik mikroba rumpun bambu yang berbeda  kedalam 5 kg  tanah per poliybag yaitu:0 g  (Kontrol),25 g,  50 g, 75 g, 100 g dan 125 g.  Berdasarkan jumlah perlakuan yang dicobakan diatas maka terdapat 6 perlakuan dan diulang sebanyak 5 kali sehingga terdapat 30 unit percobaan. Hasil penelitian menunjukkan bahwa pemberian berbagai dosis pupuk organic mikroba rumpun bamboo dapat memberikan pengaruh yang positif terhadap pertumbuhan tanaman cabai. Pada setiap perlakuan yang diberikan ternyata dosis  75 g  menghasilkan tinggi tanaman, jumlah daun, jumlah cabang, berat segar dan berat kering tajuk lebih baik dibandingkan dengan perlakuan dosis yang lain.

Abstract

The aims of this research are to determine growth and production of chili (Capsicum annuum L.) provided compost and bacteria Azotobacter sp. This study used a randomized block design factorial with two treatment factors. The first factor is compost consisting of : compost 15 t ha-1, 20 tha-1, and 25 t ha-1. The second factor is the bacteria Azotobacter sp. consisting of without giving Azotobacter sp. and giving Azotobacter sp. Each treatment was repeated four times so that there are 24 units trial. The results showed the bacteria Azotobacter sp. administration significantly affected plant height, root length, root volume, fresh weight of plants, plant dry weight, number of fruit crops, and the weight of the fruit crop. The results showed plant height, root length, root volume, fresh weight of plants, plant dry weight, number of fruit crops, and the weight of the fruit crop the highest in the delivery of Azotobacter sp. is each by 42,1 cm, 238,4 cm, 8,88 ml, 22,1 g, 5,60 g, 4,92 buah, 5,79 g. While the treatment of compost and their interaction had no significant effect on the observed variables. Key Words : Azotobacter sp., Chili, Compost, growth, production.

Abstract

Utilization of arbuscular mycorrhizal fungi (AMF) is aimed at increasing crop productivityon marginal soils.AMF role as natural microorganisms areenhancing the absorption of nutrient, especially P,helping the plant to be able to withstand drought conditions as their hyphae are able to penetrate soil pores thus expanding the areas of water absorption, and protecting plant roots against pathogen attacks. Intensive planting would disturb the populationand development of the AMF. The purpose of this study was to observe the status of AMF sporeson maize (Zea mays L.).This study used a randomized block design (RAK) with 6 treatments and 5 replicates so that there were 30 experimental units.Factors studiedare several types of AMF based on the color of the corn plant area.Data fromthe study concluded that observationof AMFspores horizontally (H1, H2, and H3) showed no difference in the density of spores. In contrast, the treatment of vertical AMF(V1, V2, and V3) decreases the number of spores with increasing soil depth.  The diversity ofcolorbased AMF spores morphological types showed that there are four groups of colors i.e.yellow, brown , black, and translucent.In the Horizontal position, most AMF spores from left to right are black, while in the vertical position the dominant color is yellow.  The natural spore density in the rhizosphere of maize(Zea mays L.)generally ranges from 35 – 124 spores/10 g soil. Keywords : Arbuscularmycorrhizal fungi (AMF ), and maize.

Abstract

The research purpose is to study the response of growth and yield of Banggaiyam ofBaku Pususvariety under various combination of inorganic fertilizer, organic fertilizers and rice straw mulch. This study used a randomized block design (RBD) consisting of seven treatments which grouped into four based on different land slopes. Thus there were 21experimental units. There was no significant effect on growth components including growth percentage, plant height and number of shoot but it was significant on plant height at 74 days after planting  (DAP).The highest plant height was 171.50 cm found in the combination of inorganic fertilizer, organic and rice straw mulch. There was alsono significant effect on the yield components except the productivity of tuber. The highest productivity was 6.33 tons ha-1shown by the combination of inorganic fertilizer, organic with rice straw mulch.Keywords : Organic, Ubi banggai (Dioscorea alata) anorganic fertilizer, Rice Straw Mulch
