Abstract

This study aims to determine the response of oil palm seedlings to oil palm bunch ashand get the composition of palm bunch ash as the optimum media mix for planting oilpalm seedlings in the ex-coal mining soil in polybag. This study used a CompletelyRandomized Design (CRD) with 4 treatments, the composition between ex-coal miningsoil and oil palm bunch ash (75%:25%), (50%:50%), (25%:75%) and six replicates.The results showed that the composition of ex-coal mining soil and oil palm bunch ashhave significant effect on seedling height, seedling diameter, number of leaves, leafarea, dry weight and root dry weight. The composition between ex-coal mining soil andoil palm bunch ash (75%:25%) gave the best results to all parameter observed.

Abstract

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

The experiment was conducted to examine the effects of indigenous mycorrhizae inoculation and cow manure doses on the growth and yield of oil palm (Elaeis guineensis) at production stages I. It was conducted at farmer plantation in Semabu Village Tebo Regency located at -1.473543, 102484062. This research was arranged in a randomized block design consisting of two factors. The first factor is inoculation of mycorrhizae isolates comprising two levels, i.e. without and with inoculation, and the second factor is the dose of cow manure comprising five levels, i.e. without cow manure, 25%, 50%, 75%, and 100% of the recommended dose of cow manure at Production Stages I (30 kg plant-1). The variables observed were plants girth, leaf midrib, number of bunches per plant, weight per bunch, weight of fresh fruit bunches per plant, and root infection. The results showed that there was interaction effect between inoculation of mycorrhizae and cow manure doses. The inoculation of mycorrhizae and cow manure at a dose of 50% of the recommended dose were able to increase oil palm growth and yield.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi tanaman kedelai yang toleran terhadap naungan dan mengetahui karakter fisiologi fotosintetik penciri toleransi tanaman terhadap naungan. Keutamaan penelitian ini adalah untuk mempelajari daya adaptasi kedelai yang tahan naungan dan mengembangkan kedelai sebagai tanaman sela pada areal di bawah tegakan. Penelitian yang dilakukan terdiri dari 2 tahap yaitu (1). Evaluasi dan seleksi varietas pada naungan buatan (naungan paranet) (2) Uji cepat pada ruang gelap (Pengelompokan tanaman toleran, moderat dan peka). Hasil evaluasi 15 varietas tanaman kedelai pada naungan buatan dan rumah gelap menunjukkan bahwa dua varietas menunjukkan konsistensi toleransi terhadap naungan, yaitu varietas Ringgit (V1), dan Petek (V13). Didapat juga tiga varietas yang moderat yaitu Kawi (V2), Cikurai (V8), dan Argopuro (5), sedangkan dua varietas peka terhadap naungan yaitu Seulawah (V4) dan Jayawijaya (V15).

Abstract

One way to improve the productivity of soybean grown as an intercropping plant in the standing area is to develop soybean varieties that are tolerant to shade. This experiment aimed to discover the physiological characteristics in soybean varieties that are tolerant to shade.The results showed that the significant physiological characteristics that determine the level of the soybean tolerance to shade are nitrogen and protein contents.The increasing of nitrogen and protein contents was higher in the tolerant varieties than those of sensitive varieties. Shade treatments affected seed weight. The soybean yield on the 50% shade decreased by 23.11% in the tolerant varieties, and about 27.63% decreased in the sensitive varieties. The yield decrease was lower in tolerant varieties compared to the sensitive varieties. This result was supported by the lower reduction in empty pods.Mechanism of tolerance to shade on soybean plant is characterized by the increase of nitrogen and protein contents. In addition, higher yields on tolerant varieties supported by high pods contain and low empty pods.Key words: Soybean, nitrogen and protein contents.

This study aimed to investigate the effect of shade on leaf chlorophyll content and the yield of two soybean varieties. The experiment was conducted at the Experimental Farm of Faculty of Agriculture, University of Jambi, located in the Village District Mendalo Jambi. Experiments using split plot design (Split-Plot Design) by 2 factors: the first factor as the main plot is a shade (N) consisting of 2, ie, without shade and 50% shade. The second factor is the subplot soybean varieties (V) consisting of varieties Petek (tolerant) and Jayawijaya (sensitive). The variables measured were plant height, chlorophyll and total weight of 100 grains, while the number of pods per plant, number of pods per plant contains, and the yield per plant showed no significant differences. Petek varieties tend to show tolerance to shade melelui increase in the number of total chlorophyll a dam to increase the weight of 100 grains were higher than Jayawijaya.Keywords: Soybean, shade, leaf chlorophyll
