Grafting bibit kopi memiliki tujuan menghasilkan tanaman dengan karakteristik terbaik dari dua varietas kopi yang disambungkan. Kopi robusta digunakan sebagai batang bawah, karena lebih tahan terhadap kondisi yang tidak menguntungkan di lahan gambut. Upaya peningkatan ketahanan batang bawah dapat memanfaatkan mikoriza dan disambungkan dengan kopi liberika sebagai batang atas. Penelitian ini bertujuan untuk  mendapatkan bibit kopi Liberika unggul hasil grafting dengan kopi Robusta bermikoriza serta mendapatkan panjang entres kopi Liberika yang mampu meningkatkan pertumbuhan bibit kopi Liberika hasil sambung pucuk. Percobaan ini menggunakan Rancangan Acak Lengkap faktorial dengan dua faktor dan empat ulangan. Faktor pertama adalah inokulasi mikoriza (tanpa aplikasi mikoriza dan aplikasi mikoriza gabungan Glomus sp-1a dan Glomus sp-3c) dan  faktor kedua berupa panjang entres (10, 15, 20 dan 25 cm). Parameter yang diamati adalah persentase keberhasilan sambungan, waktu pecah tunas, pertambahan tinggi bibit, pertambahan jumlah daun, jumlah tunas, bobot kering tunas, dan infeksi mikoriza. Hasil penelitian menunjukkan respons bibit kopi Liberika hasil grafting dengan bibit kopi Robusta bermikoriza terbaik diperoleh pada panjang entres 15 cm, sedangkan yang disambungkan dengan Robusta tidak bermikoriza diperoleh pada panjang entres 25 cm. Pertumbuhan bibit kopi Liberika hasil grafting dengan bibit kopi Robusta terbaik pada berbagai panjang entres diperoleh pada kopi Robusta bermikoriza.” The main goal of coffee grafting is to create a crop with the best characteristic of two coffee varieties in one plant. Robusta coffee is used as the rootstock, which is more resistant to constraints and unfavorable conditions in the peatland. The effort to increase rootstock resistance is inoculated by mycorrhizae and grafted with Liberica coffee as the scion. This study aimed to obtain the best scion length in order to increase the growth of Liberica coffee with Robusta coffee as the inoculated rootstock. The experiment used factorial completely randomized design with the first factor was mycorrhizae inoculation (without inoculation and inoculation of Glomus sp-1a and Glomus sp-3c combination) and the second factor was  the length of scion (10, 15, 20 and 25 cm). The variables observed were the percentage of success grafted plants, shoot break time, growth (plant height, number of leave, number of shoots, and shoot dry weight) and mycorrhizae infection. The results showed that the plant inoculated by mycorrhizae and scion lenght of 15 cm gave the best percentage of the success graft, shoot break time, and growth of scion. While, the root stock without inoculation showed the best result with the scion length 25 cm. The best growth of grafted plant was obtained in all scion length with mycorrhizae inoculation.

ABSTRACT: Cultivated and weedy rice biotypes exhibit morphophysiological variations under low light, affecting competition between plants. The aim of this study was to assess relative competitiveness between cultivated and weedy rice under full and low light. Three experiments were conducted in a greenhouse, using a completely randomized design with four repetitions. The treatments in the experiment I were arranged in additive series while in the experiments II and III treatments were arranged in replacement series. Experiments II and III were carried out concomitantly to assess coexistence between the rice cultivar and weedy rice. The treatments consisted of different plants proportions: 100:0 (cultivated rice monoculture), 75:25, 50:50, 25:75 and 0:100 (weedy rice monoculture), keeping the total plant population obtained in experiment I (240 plants m-2) constant. Experiment II was conducted with full solar radiation and III under 50% light. The variables analyzed were shoot dry weight and plant height, 35 days after emergence (DAE). Competition among plants was evaluated via graphs and by interpreting competition indices. Concerning shoot dry weight, mutual losses were recorded between competitors, whereas equal competition for resources was observed for plant height. Weedy rice was more competitive than cultivated rice regardless of the light environment assessed, indicating the need for integrated methods to control this weed.

Indonesia is one of the largest coffee producing and exporting countries in the world. Most of the production is robusta variety. Coffee is the fourth largest foreign exchange earner for Indonesia after palm oil, rubber and cocoa and is a source of income for the community. Coffee can be developed in a generative (seed) and vegetative way, including using cuttings. Efforts to accelerate the formation of roots in cuttings can be done by using natural growth regulators, one of which is shallots which contain auxins. The purpose of this study was to examine the effect of shallot extract on the growth of robusta coffee cuttings (Coffea canephora). This research was conducted from December 2019 to February 2020 at Campus II, Batanghari University (Pijoan). The design used in this study was a completely randomized design (CRD) with one treatment factor, namely shallot extract including; .k0 (without giving onion extract), k1 (250 g of shallots in 1 liter of distilled water), k2 (500 g of shallots in 1 liter of distilled water), k3 (750 g of shallots in 1 liter of distilled water), and k4 (1000 g of shallots in 1 liter of distilled water). Each stage of the experiment was repeated 3 times, so that there were 15 experimental plots, for each experiment there were 10 cuttings with a total of 150 cuttings.

Methods to improve the grain yield of red kidney bean without the addition of commercially fixed nitrogen will have significant benefits to farmers in Jamaica and other tropical regions. Red kidney beans provide a major portion of the dietary protein for most families in these regions. Our experimental objective was to evaluate the nitrogen fixing capabilities of several breeding lines of Phaseolus vulgaris when inoculated with Rhizobium strains isolated from Jamaican soils. Surface sterilized seeds of 11 Phaseolus lines were inoculated with inoculum prepared from 5 day old Rhizobium YEM mixture. Rhizobium used were T2 and B17 from Jamaica and UMR 1889. The greenhouse study was arranged as a completely randomized design. Bean lines 9056-101, 9056-98B, 8954-5 and 8954-4 showed improved nodulation and N2 fixation when inoculated with UMR 1899. The combination of breeding line 8954-5 and Rhizobium strain B17 produced the highest nodule number and shoot dry weight of 193 and 0.72 g, respectively. The Rhizobium strain B17showed some ability to compete successfully for nodule sites against known effective strains.

The Heliconias have a great potential as a cut flower and for this reason an adequate management of the crop is important. The objective of this research was the application of soil amendments (Biol and superabsorbent polymers - SAP) and the analysis on their effect in the growth of Heliconia psittacorum cv. Tropica. An experiment was established using a completely randomized design with four treatments and five repetitions: SAP (1 g plant-1), biol (20 mL plant-1) + SAP (1 g plant-1), biol (20 mL plant-1) and one control (without application). A 20 cm rhizome was planted per pot and were evaluated the height of the plant, the number of leaves, the leaf area and the number of shoots were measured. The analysis of variance did not show statistical differences (p ≤ 0.05) between treatments for the variables of the height of the plant, the leaf area and the number of shoots, but statistical differences were found for the variable number of leaves (p ≤ 0.05), and the best treatments were Biol, SAP, and Biol + SAP. With the application of the biol and SAP amendments, it was not possible to increase the plant height, the leaf area and the number of Heliconia shoots. Regarding the application of SAP to the not found significant results in Heliconia, it is expected that treatments with SAP show a better effect in the dry season.
