Abstract

 Oil palm is a widely cultivated plantation crop in Indonesia. Oil palm production is influenced by fertilizers. One of the organic wastes that can be used as fertilizer is a solid decanter. The purpose of this study was to determine the differences in growth and nutrient content of N, P and K in plants with solid decanters and those not. The research was carried out from October 2019 to March 2020 at PT. Sampoerna Agro Tbk, Mesuji Garden, Mesuji District, Ogan Komering Ilir Regency, South Sumatra. This study uses the t test with independent samples. Samples of oil palm plants used are immature oil palm plants (TBM) aged 2 years in blocks 13A and 18A which have been fertilized by NPK according to recommendations and in block 13A have been given a solid decanter of 15 tons ha-1. The results showed that plants that were applied solid decanter gave a significant difference response to plants that were not given solid decanter on the variable number of leaves, number of midribs and plant height and on nutrient levels of P and K with t test values of 0.001, 0.000, and 0.003 for variables growth and 0.006 and 0.000 in nutrient content variables. Based on the physical form, it also shows that plants that have solid decanter application have better shape, size and plant freshness than plants that are not applied with solid decanter.   Oil palm is a widely cultivated plantation crop in Indonesia.

Abstract

The use of biofertilizers is part of an environmentally friendly plant cultivation. In order to analyze the effect of soaking seeds with several types of biofertilizers on seedling growth and damping off disease in tomatoes, a greenhouse experiment has been carried out using biofertilizers and the fungicide Propineb as control treatment. The biofertilizers used were mixed biofertilizer (BION-UP), Consortium isolates of tomato rhizosphere bacteria (CITRB), consortium of Azotobacter chrococcum and Trichoderma harzianum (Azoto-Tricho). The results showed that soaking tomato seeds in bioagens solution increased plant height, number of petioles, fresh weight and dry weight of plants, as well as suppressed damping off disease in tomato nursery. The CITRB biofertilizer has a better effect on plant growth and diseases suppression than another biofertilizers and Propineb fungicide. CITRB enable to increase plant height by 49.97%, number of petioles by 60.00%, plant fresh weight by 107.23%, dry weight of plants by 129.41%, and suppress damping off disease by 56.67%. BION-UP, CITRB and Azoto-Tricho were able to suppress damping off disease by 22.22%, 27.78% and 16.67% respectively.  The ability of all biofertilizer to suppress damping off disease incidence were better than Propineb fungicide.

Abstract

Rice (Oryza sativa L.) is a staple crop that is always needed throughout the world, including Asia. Rice is one of the staple foods in Indonesia. One form of abiotic stress that becomes the main obstacle in rice production is drought stress. It is necessary to test rice varieties that are resistant to drought stress. This study aims to determine drought-resistant rice varieties based on SSR markers and to determine the morphological characteristics of drought-resistant rice. This research was carried out from January to April 2021 at the Laboratory of Physiology and Biotechnology, Faculty of Agriculture, Sultan Ageng Tirtayasa University and the Screen House of the Agricultural Technology Research Center Banten. The DNA isolation process in the molecular resistance test used the Doyle & Doyle (1990) method which used three SSR markers to detect drought resistance genes. Analysis of DNA bands using Gel Analyzer software, grouping analysis using the UPGMA method in NTSYS software. The results of the morphological study of six rice varieties on drought showed significant to very significant effects on the parameters of plant height (cm), root length (cm), number of tillers, and number of panicles. Molecular test results from three SSR primers on six rice varieties showed a high level of polymorphism with an average polymorphism information content (PIC) of 0.72 which was included in the very informative category and could be researched on drought resistance. The genetic similarity identified Jawara Hawara rice variety have drought resistance genes.

Abstract

Seedling fall disease caused by the fungus Rhizoctonia solani is one of the limiting factors in the cultivation of mustard plants. This pathogen can attack plants in the nursery as well as after the plants in the field. The aim of this study was to determine the effect of using biological fertilizers Azoto-Trico and KIBPF with different application time intervals on the development of seedling fall disease and the growth of mustard in the nursery. The study used Azoto-Tricho and KIBPF biological fertilizers with application intervals of 2 days, 4 days and 6 days. The results showed that the application of biological fertilizers Azoto-Tricho and KIBPF with different application time intervals had an effect on controlling seedling fall disease and increasing plant height and plant fresh weight. The application of Azoto-Tricho biofertilizer and KIBPF if applied at intervals of 2 days or 4 days or 6 days had the same ability to control seedling fall disease and increase plant height and fresh weight of mustard plants in nurseries.
