Abstract

Fungi mikoriza arbuskula (FMA) sebagai agensia hayati pada beberapa jenis tanaman saat ini mulai banyak mendapat perhatian, karena kemampuannya dalam bersimbiosis dengan berbagai jenis tanaman, dan membantu tanaman dalam meningkatkan penyerapan unsur hara, serta memperbaiki kualitas hasil. Dewasa ini, penting artinya mendapatkan bahan alternatif yang dapat digunakan sebagai sumber fosfor (P) yang harganya murah, aman bagi lingkungan, dan mudah tersedia. Batuan fosfat dan tepung tulang sapi merupakan jenis bahan alami yang dapat digunakan sebagai sumber P alternatif yang diharapkan dapat meningkatkan pertumbuhan dan biomassa tanaman pegagan. Percobaan rumah kaca dilaksanakan dengan tujuan menguji efektivitas FMA pada jenis dan dosis pupuk P alami terhadap pertumbuhan dan biomassa tanaman pegagan (Centella asiatica (L.) Urban). Percobaan menggunakan rancangan acak lengkap yang disusun secara faktorial. Faktor pertama ialah perlakuan FMA (inokulasi FMA dan tanpa FMA). Faktor kedua ialah dosis pupuk P alami (4 taraf dosis batuan fosfat 150, 300, 450, 600 kg ha-1 dan 4 taraf dosis tepung tulang sapi 125, 250, 375, 500 kg ha-1 serta perlakuan kontrol/tanpa pemupukan), yang diulang tiga kali. Hasil penelitian menunjukkan inokulasi FMA nyata meningkatkan jumlah daun, jumlah stolon, luas daun, bobot segar dan bobot kering biomassa tanaman pegagan. Demikian pula Pupuk P alami nyata meningkatkan jumlah daun, luas daun, bobot segar dan bobot kering biomassa tanaman pegagan. Perlakuan FMA dan pupuk P alami tidak saling berinteraksi terhadap peubah pertumbuhan dan biomassa tanaman pegagan.

Abstract

Rice is important staple food in the world. One important input in rice production is seed vigor, is determined by seed characteristics such as seed size and shape. The Digital image processing could facilitate observations of seed size faster, large samples, produce accurate, and robust data. However, this study was designed to investigate size of seed, endosperm and embryo of 55 tropical rice genotypes using image analysis and correlation anlysis between characters. A total of 400 seeds, 40 endosperms, and 8 embryos containing each genotype were investigated for their size characteristics. The results of the investigation showed that genotype differences had a significant effect on size of seed, endosperm and embryo. The length of tropical rice seeds is included in the medium-very long seeds and has a significant positive correlation (α <0.01) with the weight of 1000 grain grains, seed area, shape of the seed (length-to-width ratio), and endosperm length. Embryo size characters (length, width, area, and circumference) have a significant positive correlation (α <0.05) with seed area. The results can be considered in the crop improvement of tropical rice plants in the future.

Abstract

Black cumin (Nigella sativa L.) is a species Ranunculaceae family which grows in the Middle Eastern and Southern Mediterranean countries. Black cumin is also known as habbatus sauda , or kalonji in South Asia. Black cumin seeds are used as spice traditional medicine; the essential oil compound in the seeds has been identified as thymoquinone. Thymoquinone has a potent antioxidant effect, which could protect organs from oxidative damage by generating free radical agents. Indonesia is one of the most geographically diverse country in the world. Some regions have scattered low and high plains, abundant sunlight, evenly distributed rainfall throughout the year, and highly diverse soil types. The purpose of this study was to study the growth, production, thymoquinone and thymol content of several accessions of black cumin with different harvesting time in D3 type climate regimes. The research was conducted from April to September 2019 in Ngadirejo Village, Sukapura District, Probolinggo Regency, East Java with an altitude of 1.680 m above sea level. The experiment used a randomized complete block design with one factor for the vegetative phase, namely accession (“American”, “Indian”, “Kuwait”, and “Slovenian”) and two factors for the generative phase, namely accession and harvesting time. The harvesting time of black cumin was conducted at 6, 7, and 8 weeks after the anthesis. “Indian” and “Slovenian” accession demonstrated the best vegetative growth, whereas “Indian” had the highest capsules number per plant, seeds weight per plant, and the highest estimated production compared to other accessions (603 kg seeds. ha-1). “American”, “Indian” and “Kuwait” accessions are well adapted in D3 type climate. The harvesting time of 7 to 8 weeks from anthesis was shown to be optimal for all accessions. Thymoquinone and thymol content for the four accessions was circa 349.64– 3,030.45 μg. g-1 of seeds and 385.56 – 2,003.46 μg.g-1 of seeds, with potential production values of 0.18 - 1.83 kg.ha-1 and 0.19 - 0.45 kg.ha-1, respectively. The optimal harvesting time to maximize seed production was unaffected by the black cumin accession.

Abstract

The low productivity of soybeans (Glycine max) and the impacts of climate change have led to the need for adaptive varieties to high altitude to produce high yields. In this study, nine soybean genotypes from different geographic regions, tropical and subtropical, were tested. The aim of the research was to investigate the growth and productivity of different genotypes of soybean when grown in high-altitude environment. Results showed that the tropical genotypes, “Tanggamus” and “SC-1-8” from Indonesia, “Manshuu-masokutou” from China, and “San Sai” from Thailand, had longer growth duration than the subtropical genotypes, “Enrei” and “Fukuyutaka” from Japan, “Stressland” and “Ht-2” from the United States, and “Hakubi” from China. Tropical genotypes have greater growth values than subtropical genotypes as shown by taller plants, greater number of leaves and dry weight. Among the tropical genotypes, “SC-1-8”, which is a soybean line from IPB, showed the best growth rates and competitive crop yield, making it a potentially good candidate for high yielding soybean in Indonesia.

Abstract

The objective of this experiment was to study nitrogenase activity, nutrient uptake, and growth of two soybean varieties under saturated and dry soil conditions. The experiment was conducted in the plastic house at IPB Experimental Station, Babakan Sawah, Bogor, from August to November 2001. The experiment used the complete randomized design with four replications. The first factor was variety, consisted of Wilis and Bromo. The second factor was water condition, consisted of continuous saturated, saturated-dry, and dry conditions. Wilis and Bromo were not significantly different in nitrogenase activity; P and K uptake; nodule, stalk, leaf, pod, and seed dry weight. Wilis and Bromo were significantly different in root dry weight and leaf N uptake at 3 weeks after planting. Root dry weight and leaf N uptake of Wilis was lower than those of Bromo.The levels of nitrogenase activity, nutrient uptake, and plant weight under different water conditions were in the following order, from low to high, dry, saturated-dry, continuous. Under continuous saturated condition, nitrogenase activity, N uptake, P uptake, K uptake, nodule, root, stalk, leaf, and pod dry weight were 6800 %, 265 %, 320 %, 288 %, 1386 %, 362 %, 289 %, 265 %, 329 % of those under dry condition, respectively at 9 weeks after planting.    Key words:  Soybean, saturated culture, dry culture, nitrogenase activity, nutrient uptake

Abstract

Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. By keeping the water-table constantly, soybean will be avoided from negative effect of inundation on soybean growth because soybean will acclimatize and improve its growth. The objective of the research was to study the response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip of  Tanjung Lago Sub District, Banyuasin District, South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main plot was water depth in the furrow consisted of without watering, 10, 20, 30, 40 cm under soil surface (uss). The subplot was soybean variety consisted of Tanggamus, Slamet, Willis, and Anjasmoro. The result showed that the interaction between varieties and water depth significantly affected growth and seed production, except pod numbers/plant. The values of all variables were higher under SSC compared to those cultivated without watering (control), but varieties responded to SSC differently. The highest seed production was obtained from Tanggamus with 40 cm uss, i.e. 4.83 ton/ha but it was not significantly different from those at water depth 20 (4.63 ton/ha) and 30 cm uss (4.71 ton/ha). However, technically and economically, 20 cm uss was the most appropriate water depth for soybean production on tidal swamps.   Key words: Glycine max L. (Merr.), water management, water table

Abstract

The objective of the research was to study the nutrition uptake (nitrogen, phosphorus, and potassium,) and the grain production of five rice varieties representing modern, new plant type and local varieties under application of inorganic, organic and combined inorganic-organic fertilization. Five rice varieties were Way Apoburu and IR-64 (modern varieties), Midun and Sarinah (local varieties from Sukabumi and Garut, respectively), and Fatmawati (new plant type variety).  Five fertilizer treatments were (1) full recommendation dosage of inorganic fertilizer (250 kg urea/ha, 100 kg SP-36/ha, and 100 kg KCl/ha), (2) ¼ recommendation dose of inorganic fertilizer + rice straw, (3) ½ recommended dose of inorganic fertilizer + rice straw, (4) rice straw, and (5) green manure from Crotalaria juncea biomass. The results showed that there was no specific response of rice varieties to the fertilization treatments, even though there was specific nutrient uptake pattern and yield of each variety, and there was significant effect of fertilizer treatment to nutrient uptake and rice yield. Nutrient uptake and grain yield indicated that nutrient imobilisation occurred at 1stseason, however the availability of N, P, K nutrients increased at 2nd and 3rdseason on rice straw and green manure treatments. Rice straw application caused lower nutrient uptake and grain yield than full dosage inorganic fertilizer at 1st season but both were not significantly different at 2nd and 3rdseason.  Application of rice straw with  ½ dosage of inorganic fertilizers was not significantly different from full dosage of inorganic fertilizers in nutrient uptake and grain yield. Modern varieties showed higher level of N absorption than that of new  type variety although it was not significantly different with that of local varieties, whereas the P and K uptake of modern varieties was lower than that of local and new plant type varieties. The modern varieties also showed higher level of dry grain per hill than that of local and new plant type varieties. However yield per ha of all varieties tended to be similar.   Key words: uptake, efficiency, mineral nutrition, variety, lowland rice
