Abstract

Siam Banjar Citrus has a very bright prospect to be develoved, becomes a contributor to the national fruit products with various types and varieties and has the production that does not depend on seasons. Diplodia disease in citrus still becomes a major problem because it causes loss of high yield and affecth the gain of production. The disease, caused by Botryodiplodia theobromae pat., indicates symptoms of lesions on citrus trunk, such as narrow lines on the trunk, and can cause plant death due to the disruption of transport of water and nutrients from the soil to the plants. The objectives of the research were to find out the effects of the interaction between Trichokompos fertilizer sp.,to determine the combination of Trichokompos fertilizer and Tricjoderma sp. Solution for Diplodia disease control. The study was conducted from january to april 2012, in Rantau Badauh sub- district. This experiment employed Randomized Blok Design (RBD) consisting of three replications and two factors , namely the dosage of Trichokompos fertilizer (0 kg, 10 kg and 20 kg), and the dosage of Trichoderma sp. (0 g/l lt EKG, 50 g/l lt EKG , 100 g/l lt EKG, 150g/l lt EKG and 200 g/l lt EKG). The observations were conducted on the presence of fungi and the measurement of bark lesions. The result showed that there was no intraction between the two treatmeants, and the significant effect of the application of Trichoderma sp. Against the widespread symptoms of doplodia at all observation time with the best dosage was 50 g/l ECG. The results of the regression indicated that the higher concentration and the longer time of the applicatin of Trichoderma sp. Would reduce the widespread of symptoms caused by diplodia in citrus.

Abstract

The raised-bed soil is a land management technology in South Kalimantan. Adding Ameliorant to the raised-bed soil as an effort to increase the utilization of support for the cultivation land. Chlorophyll or leaf green substances found in all green plants that carry out photosynthesis. Ameliorant applications can increase the chlorophyll content of plants to optimize plant growth. This study aims to look at the effect of giving several types of ameliorant to the content of chlorophyll (chlorophyll-a, chlorophyll-b and total chlorophyll) and the growth of corn planted on raised-bed soil. This research is an experiment in the laboratory and a greenhouse. This research was conducted using a Completely Randomized Design (CRD) Single Factor with the treatment tested was the type of ameliorant soil without treatment (control - K), soil + agricultural lime (dolomite - C), soil + palm empty fruit bunch ash (S), soil + rice husk ash (P) and soil + coal ash (B). All treatments were repeated 5 (five) replications so that there would be 25 units of the experiment. The results showed that the application of ameliorant in raised-bed soil using dolomite and oil palm empty fruit bunches ash with a dose of 5 tons ha-1 affected the content of chlorophyll-a and total chlorophyll in the growth of corn planted in raised-bed soil materials.

Abstract

Keseragaman dalam Galur dan Keragaman antar Galur Padi Mutan M5 Berbasis Irradiasi Varietas Lokal Kalimantan Selatan. Preferensi petani lahan rawa terhadap padi varietas lokal tinggi, namun varietas lokal berumur panjang dan hasilnya rendah, sehingga perlu perbaikan varietas lokal.  Penelitian ini merupakan bagian kegiatan perbaikan padi varietas lokal untuk menghasilkan galur-galur harapan berumur pendek-sedang, sedangkan butir gabah yang ramping dan pera tetap dipertahankan.   Tujuan dari penelitian ini adalah untuk mengetahui keseragaman dalam galur  dan keragaman antar galur M5.  Penelitian dilaksanakan di Sawah Percobaan Fakultas Pertanian Universitas Lambung Mangkurat sejak Maret - September 2014. Penelitian menggunakan 300 galur terpilih tanpa ulangan.  Keseragaman dalam galur dianalisis dengan membandingkan ragam masing-masing galur mutan  dengan ragam tetuanya.  Keragaman antar galur dilakukan dengan membandingkan ragam semua galur  dengan tetuanya.   Hasil penelitian menunjukkan bahwa sebagian besar galur M5 asal tetua Siam Harli dan Siam Kuatek  sudah seragam, sedangkan ragam galur tetua Siam Harli dan Siam Kuatek tidak berbeda nyata dengan galur-galur M5, tetapi  sebagian galur tetua asal Siam Harli maupun Siam Kuatek lebih baik  daripada tetuanya, sehingga berpeluang untuk memilih galur-galur yang lebih baik daripada tetuanya.
