Utilization of arbuscular mycorrhizae fungi (FMA) is an alternative way to improve soil fertility. Therefore, it must be developed by studying deeply the effectivity of the FMA. This is important due to either its ability to associate with almost all of vegetation family in terrestrial ecosystems or its ability to increase plant growth rate, seedlings quality, and crop yield, especially on critical land. A research about effectivity of variously indigenous arbuscular mycorrhizae fungi on P-sorption and Jatropha growth was conducted at laboratorium and glasshouse Agriculture Faculty, Andalas University. This research was aimed to gain the most effective isolate of arbuscular mycorrhizae fungi on growth of and P-sorption by Jatropha (Jatropha curcas L.) plant on critical land. Single isolat such as Glomus sp2, Acaulospora sp1, Gigaspora sp1, and compound isolate M7 (Glomus sp2,+ Acaulospora sp1 + Gigaspora sp1) significantly affected plant height, canopy dry matter, infection percentage and intensity, and P-sorption. M7 Compound isolate was the most effective innoculum. By this isolate, height of Jatropha seedlings was 27.5 cm, canopy dry matter 5.9 g, infection percentage 78.5%, infection intensity was 49.1, and P-sorption by canopy was 1.6 g for each seedling.

Karbon (C) organik tanah yang merupakan bagian utama dari bahan organik tanah mengalami penurunan sebagai akibat perubahan-perubahan penggunaan lahan dari kondisi alami menjadi lahan-lahan pertanian. Penurunan C organik tanah menjadi semakin besar karena masukan bahan organik yang rendah dan bila penurunan ini. berlangsung terus menerus maka pada akhirnya menyebabkan degradasi tanah. Artikel ini membahas peranan, dekomposisi dan struktur dari bahan organik tanah dalam hubungannya dengan dinamika fraksi C organik tanah pada pengelolaan lahan yang berbeda di daerah tropis basah. Perubahan penggunaan dan pengelolaan lahan menyebabkan terjadinya perubahan C organik total dan fraksi-fraksi C organik labil dan stabil tanah. Beberapa penelitian telah menunjukkan bahwa fraksi C organik labil seperti C organik partikulat lebih responsif terhadap perubahan-perubahan dari pengelolaan tanah dan merupakan suatu indikator yang sensitif dari kualitas tanah. Disamping itu fraksi C organik stabil seperti asam humat yang mengalami perubahan karena praktek-praktek pengelolaan tanah dapat digunakan untuk menilai kapasitas potensial tanah sebagai penyimpan karbon. Perubahan-perubahan penggunaan lahan dan pengelolaan tanah mempunyai pengaruh negatif dan positif terhadap C organik total, fraksi C organik labil (C organik partikulat) dan fraksi C organik stabil (asam humat). Praktek-praktek pengelolaan yang dapat mempertahankan dan memperbaiki fraksi-fraksi C organik tanah meliputi sistem agroforestri, aplikasi pupuk organik, mulsa dan pengembalian sisa tanaman ke dalam tanah. Fraksi C organik partikulat dan asam humat menunjukkan perubahan-perubahan yang lebih besar dibandingkan C organik total akibat perubahan-perubahan penggunaan lahan dan praktek-praktek pengelolaan tanah di daerah tropis basah.Key words : Fraksi C organik, penggunaan lahan, tropis basah

Sidimpuan snake fruit is one of the local specialties of Padangsidimpuan City in Sumatra. The fruit is known for its sweet, sour and astringent taste which differentiates it from Pondoh and Balinese snake fruit. However, snake fruit farmers have been experiencing an increasing failure rate of fruit-set during the off-season which has led to a decrease in production. Â Â Use fertilization and drip irrigation in the off-season has been suggested as a solution. This research investigates the use of these to overcome the failure of fruit set to optimize production of Sidimpuan snake fruit throughout the year by determining the optimal dosage of ammonium sulfate fertilizer and drip irrigation for fruit set and production in the off-season. This research used a split-plot design with the main plot for drip irrigation and the subplot for ammonium sulfate. Observation parameters include the number of flower and fruit bunches, fruit set percentage and a nutrient analysis of the leaves. The results revealed that drip irrigation had a significant effect on the observed variables of fruit set and number of harvested fruit bunches.Â Drip irrigation had a significant effect on the fruit set percentage and the number of harvested fruit bunches. The best combination of treatments was also discovered to be 400 g ammonium sulfate fertilizer per plant and drip irrigation 3000 ml/plant. The fertilization period of July-Sept gave an off season harvest that was able to match the fruit set percentage (10.76% difference) and number of fruit bunches that were formed (25.65% difference ) by the April-June fertilization for the on-season harvest demonstrating that drip irrigation and ammonium sulfate can overcome fruit set failure in Sidimpuan snake fruit during the off-season.

Peningkatan Kapasitas Sink pada Tanaman Melon (Cucumis melo L.) dengan Pemberian Giberelin Siti Fatonah; Musliar Kasim; Auzar Syarif
Jurnal Sagu Vol 8, No 02 (2009)
Publisher : Universitas Riau

For cultivation of melon (Cucumis melo L.), farmers only keep one fruit per plant to maintain quality fruit. To improve productivity, one possible effort is by spraying gibberellins at melon in combination with increasing amount of fruit maintained for each plant. The aim of this study was to know the effect of gibbereline in improving sink capacities of melon when fruit amount is increased. Gibberelins was sprayed at concentration of 0, 30, 60, and 90 mg/l to melon crop with different fruit amount per plant (one, two and three fruit). The study indicated that for melon plant with more than one fruit per plant, gibberellins application was not able to maintain the fruit quality, because the fruit weights were still decreasing. Thus, gibberellins application was not able to improve the sink capacities if fruit amount per plant is increased. While for plant with only one fruit, spraying 60 and 90 mg/l gibberellins can improve the fruit weight, so gibberellins improves the sink capacities if only one fruit is maintained for each plant.

Reforestation is an effort to restore, maintain and improve the condition of the land so that it can be used optimally according to its original function. Several steps to realize the reforestation of the residential environment in a narrow area include utilizing the existing land, choosing suitable plants, and providing utmost care. This activity aimed to increase public understanding and knowledge regarding narrow land for reforestation in urban areas. The method used was a direct approach, namely, conducting interviews with the community and holding outreach and direct demonstrations in the field. The result of this empowerment activity was that the communities, especially the residents of Palimo Indah, are very enthusiastic about participating in the greening of the environment. The selected plants consider their multifunctionality for the environment's good, such as the absorption of air pollution and family medicinal plants. The three tree seedlings are useful for reforestation and have economic value, namely the Sungkai plant, Petai tree, and Agarwood sap-producing plant. Planting has been carried out at several location points by collaboration as a form of community empowerment, namely on the park's outskirts and on the riverbanks in the Palimo Indah, Pauh District, Padang.
