Abstract

Metode pengendalian gulma yang tidak efektif akan menyebabkan dinamika gulma ke jenis yang lebih sulit dikendalikan dan tertundanya matang sadap 2-3 tahun. Penelitian ini untuk  mengkaji pertumbuhan gulma dan tanaman karet akibat pengaruh berbagai  interval pengendalian dan aplikasi herbisida pada kebun karet TBM. Penelitian dilaksanakan dari Januari 2013 sampai Juni 2014.  Rancangan penelitian Split Plot,  petak utama  adalah perlakuan interval  pengendalian gulma dan perlakuan herbisida sebagai anak petak dengan ulangan 3 kali. Hasil penelitian menunjukkan bahwa pertumbuhan  gulma daun lebar  lebih dominan  (SDR 52,76%) dari gulma sempit (SDR 47,24%) di awal penelitian (pra perlakuan). Bobot kering dan penutupan gulma lebih rendah, pada  interval pengendalian lebih singkat. Bobot kering gulma antar petak perlakuan berbeda nyata  pada Juni dan Desmber 2013.  Bobot kering dan penutupan gulma terendah  pada perlakuan  glifosat + metil metsulfuron  yang tertinggi pada perlakuan ditebas dan kontrol. Bobot kering dan penutupan gulma selalu berbeda nyata antara perlakuan glifosat + metil metsulfuron dengan perlakuan ditebas dan kontrol. Perlakuan herbisida campuran parakuat + metil metsulfuron menghasilkan pertumbuhan lilit batang karet lebih baik (17,9 cm) dibanding  perlakuan glifosat + metil metsulfuron (16,9 cm). Pertumbuhan lilit batang tanaman karet  sangat dipengaruhi  bobot kering  gulma dengan nilai koefisien diterminasi  R2  = 0,82. Dapat disimpulkan bahwa perlakuan herbisida  glifosat + metil metsulfuron lebih efektif menekan pertumbuhan gulma dan  pertumbuhan  lilit batang  karet sangat dipengaruhi bobot kering  gulma yang membentuk pola hubungan pertumbuhan negatif.

Abstract

Porang plant is atubers that havevarious benefits. Porang cultivation needs intensive management through cultivation efforts which of course must be supported by the availability of seeds. Therefore, it is necessary to procure porang seeds from vegetative (tubers) and generative (stem bulbil and branch bulbil). This study aims to obtain the best growing media for porang germination from various types of bulbil. The method used in this study was a factorial randomized block design. The way of working in this research is: Preparation of Seedling Media, Preparation of planting material (Bulbil), Seeding, Maintenance (including watering and weeding). The results showed that there was no significant interaction between the planting medium and the type of bulbil, the media had no significant effect on all observed variables, while the bulbil had a significant effect on the percentage of germination growth, stem height, and number of leaves. The best type of bulbil for breeding is stem bulbil which is superior to the variables of plumule emergence time, petiole length, stem height, and number of leaves compared to branch bulbil. Meanwhile, the best growing media in porang nurseries was a mixture of 50% husk charcoal + 50% sawdust on the variables when the plumule appeared, the percentage of germination, petiole length and stem height. The appearance of bulbil from stems on a mixture of 50% husk charcoal + 50% sawdust media, namely the time of emergence of plumules (5.61 days), percentage of sprouting (86.67%), petiole length (8.72 cm), height stems (31.11 cm) and number of leaves (7.72 strands).

Abstract

Weed is one of limiting factors in the direct-seeded rice cultivation. Cost incurred by farmers to control weeds is still quite high. Various techniques of weed control need to be evaluated to obtain the most effective weed control in tidal land. The experiment was conducted in tidal land fields in the Telang  Sari village Tanjung Lago Sub District Banyuasin District during November 2012−March 2013. The experiment was arranged in a split plot design with planting density (K) as main plot and weeding methods (P) as sub plot. Five levels of planting density at 20, 40, 60, 80 and 100 kg rice seed/ha and four levels of weeding methods (manual weeding, dimethyl amine herbicide, penoxulam, and no weeding) were used in the experiment. The treatment was repeated 3 times and applied in 4×3m plot. Components of plant growth and yield of rice plants were measured and analyzed using Microsoft Excel and SPSS 17.0. The results showed that methods of weed control did not significantly affect plant height, plant biomass at 4 weeks after seeding and number of tillers, but significantly affect number of empty grain and filled grain per panicle. Both planting density and method of weed control significantly affect yield, but no significant interaction between treatments. Planting density did not significantly affect plant biomass from age 8 weeks after seeding. Yield of planting density at 80 kg seed/ha was not significantly different from the yield of 40−60 seed/ha. Method of weed control was significantly affecting the rice yield. Weed control can increase crop yields by 37.7%.

Abstract

Red rice was one species of rice in Indonesia that was superior in nutritional content and selling price compared to white rice but the productivity of red rice is still low. One of way to improved rice growth and productivity is fertilization red rice was one type of rice in Indonesia that contains high nutrition. This research aimed to observe the effects of  the combination of organic and inorganic fertilizers on the growth and yield of red rice (Oryza nivara L.). The research used a Randomized Completely Block Design (RCBD) with 7 treatments. Each treatment had 3 replications and each experiment unit consisted of 3 plants so that there were 63 plants. The best treatment was compost of oil palm empty fruit bunch (125 g) + N, P, and K fertilizer 50%. The highest production was on oil palm empty fruit bunch compost (125 g) + Fertilizer N, P and K 50%,  it was equivalent to 5.49 ton/ha. In the red rice crop farming system it can be recommended to provide a combination of oil palm empty fruit bunch (125 g) compost and 50% N, P and K fertilizer to increase yields in the cultivation of red rice.

Abstract

This research aimed to study the influence of phosphate fertilizer and plant growth regulator applications on the growth and yield of ratoon rice grown on swampland. The research was conducted in September 2016 to January 2017 at the greenhouse of Department of Soil Science, Faculty of Agriculture, Sriwijaya University. Soil characteristics were analyzed in the Laboratory of Chemistry, Biology and Soil Fertility, Department of Soil Science, Faculty of Agriculture, Sriwijaya University. The experiment was arranged in a factorial Completely Randomized Design.  The first factor was the phospate fertilizer dosages, i.e. 150 kg ha-1 (P1), 200 kg ha-1 (P2), 250 kg ha-1 (P3). The second factor was the plant growth regulator treatments, consisting of control (Z0), Cytokinin 20 ppm (Z1), Gibberellin 60 ppm (Z3). The results showed that the application of P fertilizer did not affect the yield and growth of ratoon rice. However, the application of Plant Growth Regulators resulted in a significant effect on the growth and yield of ratoon rice. The application of Plant Growth Regulator of Gibberellin with the dosage of 60 ppm was able to increase the percentage of filled grains (84.93%), decrease the percentage of empty grains (15.07%), increase the weight of 100 grains (3.63 g) and increase the dry weight of  milled grains (7.80 Mg ha-1). It is suggested that the treatment resulted in better plant growth and yield obtained in the current study might be recommended for ratoon cultivation in swampland.

Abstract

Drought condition during the dry season is a major constraint for intensifying agricultural activities at riparian wetlands in Indonesia, particularly for annual vegetables, including common bean (Phaseolus vulgaris L.). Besides inhibiting growth and reducing yield, drought also causes alteration of the shoot and root growth and development. The objective of this study was to evaluate responses of common bean to three durations of drought stress and the bean ability to recover after termination of the stress treatments. Gradual drought stress treatments were imposed by withholding all water sources to the treated plants. Three durations of drought stress imposed were 4, 8, and 12 days. The ability of the stress-treated plants to recover was evaluated at 7 days after termination of each treatment. The result of this study revealed that common bean was able to tolerate and recover from gradual water deficit for up to 8 days; however, prolonged water deficit for 12 days inhibited the growth of above-ground organs in common bean. Despite root regrowth during the recovery period, plants previously treated with 12 days of drought were unable to recover but those treated with shorter drought stress period were able to recover.
