Abstract

Amorphophallus muelleri Blume locally called Iles-iles or porang becomes a new commercial commodity in Indonesia. The tuber as the most economic value contains high glucomannan. It has been speculated that the high variation in production among farmers is due to different planting materials and soil organic carbon (SOC). Thus, the research aimed to evaluate the growth and yield of A. muelleri from different planting materials and levels of SOC. The research was carried out at Leuwikopo Experimental Station IPB Bogor from December 2021 to August 2022, using a nested design. The main plot was the level of SOC (2%, 3%, 4%, 6%), and the sub-plot was planting materials (seeds, bulbils, and tubers from leaf cuttings). The results showed SOC status determined growth and yield. Plant height, stem diameter, number of leaves, canopy width, leaf greenness, number of tubers, weight, and size of tubers, stomatal conductance, and intercellular CO2 were significantly affected by SOC level. SOC at a level of 6% stimulated the highest growth and yield. Planting materials also determined the growth and yield. Plants originating from bulbils produced the highest yields, followed by tuber from leaf cuttings, and seeds. It is recommended to plant bulbils accompanied by maintaining SOC at a level of 6%.

Abstract

The availability of nutrients in plants depends on the ability of plants to absorb nutrients from the soil. One of the processes absorbed by plants is by the presence of the transpiration process.  Good transpiration will provide enough nutrients for plants which increase the productivity and quality of mangosteen. One of the quality standards of mangosteen fruit for export quality is the free from yellow sap contamination. It can be possible that transpiration can improve the quality of mangosteen fruit by applying fertilization. In this study Ca fertilization was carried out on mangosteen seeds, where this study aims to investigate the effectiveness of Ca uptake by mangosteen plants with the level of water loss by transpiration. This research was conducted in November 2016-March 2017 at the Leuwikopo Experimental Garden, Bogor Agricultural University. Morphological observations were carried out in its Experimental Garden and the Postharvest Laboratory whileanalysis of calcium content of plant tissue was done at the Department of Agronomy and Horticulture, Bogor Agricultural University. Data obtained then were analyzed using ANOVA test. If the results were significant, Duncan Multiple Range Test (DMRT) was then tested at 0.05 probability level. The results revealed that the transpiration rate of mangosteen plants from several treatments showed a significant difference, the transpiration rate was higher, especially in fertilized plants. The size of the 12th leaf, plants treated with fertilizer have a larger size than the treatment without fertilization. Fertilizing and providing enough water can maintain the growth of the plants.

Abstract

Maize and peanuts are important food crops in Indonesia and are generally planted in monoculture and intercropping systems. The water required for monoculture and intercropping is believed to be different. However, comparison analysis of water requirements in monoculture and intercropping is rarely conducted. The research aimed to evaluate the growth and production of sweet corn and peanuts in monoculture and intercropping systems concerning water requirement and crop coefficient. The study was conducted at IPB Experimental Station in Leuwikopo, Bogor, Indonesia from September to December 2022. Sweet corn and peanuts were planted in different cropping systems, i.e., monoculture and intercropping. Water consumption of both cropping systems was evaluated in every growing stage. The experiment used a completely randomized block design and was repeated three times. Results showed that sweet corn growth was not significantly different among cropping systems, but yield from intercropping was lower than monoculture. Intercropped peanuts grew lower than monoculture but did not show any significant difference in yield among cropping systems. Water use efficiency in intercropping was higher than monoculture for both crops, indicating intercropping is a suitable cropping system for limiting soil water availability. The land equivalency ratio was 1.80, concluding that intercropping was more efficient than monoculture in land use by 80%.

Abstract

Tomato becomes important as under-storey crop in agroforestry in Indonesia. However, farmers claim that there is yield reduction under such system. Hence, six tomato genotypes were planted under 50% reduced sunshine and full sunshine as control using randomized block nested design with genotype as main plot. The study was carried out in December 2016 to March 2017 at Cikarawang Experimental Farm, IPB Bogor. Research aimed to evaluate the production stability of tomato genotypes under shading treatment. Results showed that 50% shading affected tomato production and disease incident. Number of collected-fruit was 15-60% higher under 50% shading except for Apel Belgia and Tora genotypes that tended to decrease. Incident of gemini virus decreased by 80% and its severity decreased by 70% under 50% shading. However, 50% shading reduced tomato yield at rate 24.1% in each harvesting cycle due to a tendency on reduction on individual fruit size, irrespective genotypes. Present study demonstrated that genotype and disease incident determined tomato yield under shading. It needs further evaluation on the cause of low disease infection under 50% shading.

Abstract

Bawang merah merupakan komoditas sayuran prioritas nasional karena telah dikenal luas penggunaannya di masyarakat Indonesia. Namun, produktivitas bawang merah di Indonesia mengalami stagnansi, yaitu 9-10 ton ha-1 (2000-2018). Penerapan pertanian presisi melalui fertigasi menggunakan irigasi tetes menjadi altenatif solusi untuk menjawab tantangan tersebut. Tujuan penelitian ini adalah untuk mendapatkan teknologi fertigasi yang dapat diimplementasikan dalam budidaya bawang merah di lahan kering. Penelitian dilaksanakan di Kebun Percobaan Cikarawang, IPB University, dari September hingga November 2022. Penelitian menggunakan RKLT split plot faktorial sebanyak 6 ulangan dengan jumlah selang irigasi (1 dan 2 selang) sebagai petak utama dan kepadatan populasi (normal = 200,000 tan ha-1 dan rapat = 400,000 tan ha-1) sebagai anak petak. Secara umum kepadatan populasi tanaman lebih berpengaruh signifikan terhadap pertumbuhan dan produksi tanaman dibandingkan jumlah selang irigasi tetes. Satu selang irigasi per bedeng cukup untuk mendukung pertumbuhan dan produksi bawang merah di lahan kering. Tinggi tanaman pada perlakuan satu maupun dua selang irigasi setara, berkisar antara 32.81-33.70 cm. Produktivitas tanaman pada perlakuan satu maupun dua selang irigasi setara, yaitu 11.21-12.19 ton ha-1. Populasi yang padat mampu meningkatkan produksi, namun menghasilkan umbi berukuran kecil yang cocok untuk benih. Penentuan kepadatan populasi tanam sebaiknya disesuaikan dengan tujuan produksi dan kebutuhan pasar.

Abstract

Coromandel, or Chinese violet (Asystasia gangetica), is an invasive weed on many plantations in Indonesia, especially oil palm plantations. The A. gangetica is suspected to produce allelopathic compounds. However, the evaluation of the effect of A. gangetica on plant growth is still rare. The research objective was to evaluate the effect of allelopathic compounds of A. gangetica on the growth and production of sweet corn as a test plant. An experiment with a randomized complete block design and four replications was conducted from March to September 2022 at the Agribusiness and Technology Farm IPB. The treatment was the A. gangetica population consisted of 0 (control), 1, 2, 4, 8, and 16 individuals per pot. A. gangetica were initially planted from seeds, and the stems were slashed 5 cm above the soil surface two months after planting. One week after cutting, sweet corn seeds were planted and maintained until harvest 72 days after planting. The results showed that the allelopathic effect of A. gangetica was evident in growth of sweet corn plant. Increasing number of A. gangetica per pot increased the allelopathic effect. The most significant effect was from 16 populations per pot, which significantly reduced the growth of sweet corn height, stem diameter, leaf size (length and width), leaf number, and color. The particular population per pot also decreased sweet corn yield, i.e., weight per cob with and without husk, and cob diameter by 18.95%, 22.0%, and 19.37%, respectively. The level of sweetness decreased by 31.24% after sweet corn was planted in the remnant of 16 individuals A. gangetica per pot. Nevertheless, A. gangetica did not significantly affect leaf area index, cob length, and sweet corn biomass, including shoot and root dry weight at harvest. It would be interesting to evaluate the effect of A. gangetica in the field. Keywords: allelopathy; Brix; indole-3-carboxaldehyde; secondary metabolites; weeds

Abstract

Underground corm of Amorphophallus muelleri Blume contained glucomannan, a raw material widely used in beverage, food and medicinal industries. In Indonesia, A. muelleri is grown under intercropping system, however, average corm production was considered low. The low productivity could be related to the low input of chemical fertilizers. Therefore, the effects of NPK fertilizers and methods of application on A. muelleri productivity were evaluated in the present study for intercropping system. Two experiments were conducted at Leuwikopo Experimental Farm, Bogor, Indonesia from 2010-2012 under canopy of coffee trees. First experiment was conducted using four levels of N, P, and K applications, i.e., N:P2O5:K2O at the rate 0:0:0, 100:60:80, 125:60:100 and 150:60:120 kg ha-1. In second experiment, N:P2O5:K2O fertilizers at the rate of 100:60:80 were applied by conventional (solid) and liquefied. Results of first experiment showed that application of N, P and K at rate of 100 kg, 60 kg, and 80 kg ha-1 produced fresh corm weight 636.3±91.7 g per plant or increased by 63% higher than control. However, higher rate of NPK application did not increase corm yield, possibly due to the occurrence of leaf discoloration. Higher rates of NPK also delayed harvest time 1 to 2 weeks compared with control and caused wide variation of corm size. Thus, excess application of NPK should be avoided for high productivity of A. muelleri. Second experiment showed that there was no significant different among methods of application on fresh corm weight, i.e., 413 g and 396 g from conventional and liquefied applications, respectively. These experiments conclude that application of NPK is important to enhance A. muelleri production in intercropping system.
