Abstract

Problems of forage management in the integration of livestock into oil palm and rubber plantations in Indonesia are declining of light as the canopy of the plant increases and acid soils containing low available P, Cu, and Zn. The objective of experiment was to study the effect of shading and arbuscular mycorrhizal fungi (AMF) inoculations on the production and content of P, Cu, and Zn of Pueraria phaseoloides (Roxb.) Benth (puero). The experiment was arranged according to the split plot design with three replicates in a green house. Treatments tested were shading as the main plot (0%, 25%, 50%, and 75%) and AMF inoculations as sub plots (indigenous AMF, Glomus manihotis, indigenous AMF + G. manihotis and no inoculation). Root biomass was affected by shading level while leaf stem ratio was affected by both shading level and AMF inoculations. Inoculations with G. manihotis and indigenous + G. manihotis indicated higher herbage production and P contents than inoculations with indigenous AMF. Effectiveness of AMF inoculation on improvement of production and P uptake varied according to shading conditions. P. phaseoloides was tolerant to shading up to 50% and its production and P content as responses on inoculation of AMF were affected by soil conditions and shading intensity. Inoculation of G. manihotis and its combination with indigenous AMF improved production and P content of Pueraria phaseoloides in shading level upto 50%.

Abstract

Carbon emissions is one of the activities of agroecosystem impacts of oil palm on peat land as a result of the making drainage and plant growth. This research was conducted in the area of oil palm agroecosystem on peat land landscape, Ogan Komering Ilir District, South Sumatra with the aim of estimating reserves and carbon emissions on the land. Contribution of carbon emissions on the land with plant age 5, 3 and 2 years without drainage channels are respectively 12.027; 11.262 and 9.783 tons CO2/year, as well as plants age of 5 years with the drainage channel is 14.723 tons of CO2/year. Contribution of carbon emissions from the making drainage channel reaches 2,696 tons of CO2/ha/year and greater than the contribution of carbon emissions from the aging plant palm oil annually, amounting to 0.383 to 1.479 tons of CO2/ha/year.

Abstract

Achadi T, Haikal U, Angraini L, Ghifari MA, Yakup Y, Marlina M, Warsito W. 2022. Growth and yield of legume crops with liquid organic from various fruit residues. In : Herlinda S et al. (Eds), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 217-225. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Liquid organic fertilizer is the result from decomposition of organic matter derived from animals or plants. Liquid organic fertilizer is made from damaged or rotten fruit and from the skin of the fruit (banana, papaya, pineapple and a mixture of all three). This study aimed to determine the effect of liquid organic fertilizer (POC) on the growth and yield of legumes (Soybeans, Peanuts and Green Beans). This research was conducted from July to October 2022. This study used a Complete Randomized Design with eight treatments including controls, namely A (recommended NPK fertilizer), B (POC of banana fruit residue), C (POC of pineapple fruit residue), D (POC sis of Papaya fruit), E (POC of banana + pineapple fruit residue), F (POC of banana + papaya fruit residue), G (POC of pineapple fruit residue + papaya) and H (remaining banana fruit + pineapple + papaya). The results showed that liquid organic fertilizer were not significantly different the recommended NPK fertilizer to all variables with out number of branches and productive branch of Soybeans and numbers of branches of Peanuts so hope that liquid organic fertilizer from Various Fruit Residues increase to Yield of Legume Crops (Soybeans, Peanuts and Green Beans).

Abstract

Yohanes N, Yakup Y.  2022. Effect of planting media and liquid fertilizer dosage on oil palm growth in main nursery. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 641-650.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One of the advancements in oil palm cultivation is seeding techniques and the development of superior seeds. This study aimed to investigate the effect of manure on growing media and bio fertilizer is best to growth of oil palm seedlings in the main nursery. This research was conducted in the village of Suka Sari, District Alang-alang Lebar, Palembang. This research used Randomized Factorial Design (RAKF) with 3 replications. The first factor is manure treatment that consisted of three treatments P1 (0%), P2 (25%), P3 (50%), and the second factor giving biofitalik with three treatments and three times the B1 (5 cc/l), B2 (10 cc/l), B3 (15 cc/l). Observations were obtained concentrations of manure significant effect of the number of leaves, and no significant effect on plant height increment, increased girth, plant weight, root fresh weight and dry weight of roots. In general liquid fertilizer has not significantly influenced all parameters were observed. Interaction between treatment of manure and liquid fertilizer biofitalik no real effect.
