Yellow leaf curl disease of chili pepper caused by Pepper yellow leaf curl virus (PYLCV) has been reported as an important disease in Java and Bali. Disease severity reached 80−100% and it may cause significant yield losses. In order to reduce the negative impact of synthetic insecticides, silica application was evaluated for its potency to suppress the disease. A greenhouse experiment was conducted using randomly block design with 2 factors: PYLCV isolate (Java and Bali) and silica (SiO2) treatment (with and without). Parameters observed were disease symptoms, incubation period, disease incidence and severity, and total silica level. The symptoms of virus infection in Pelita 8 and Seret cultivars were yellow mosaic, leaf curl, green mosaic, dwarf, and cupping upward or downward. A Specific DNA fragment of 912 bp was successfully amplified from 4 samples. Four sequences were obtained and further analysis showed their highest homology, i.e. 96% and 97% with Pepper yellow leaf curl Indonesia virus-Java (PYLCIV-Java) (JX416180) and PYLCIV-KrthAl (LC381274), respectively. Infection by different virus isolates did not affect disease severity significantly. The application of silica was able to delay symptom development and to suppress the severity of the disease in the range of 16.67−30.33%. Silica application on the soil increased the total content of silica in the plants. However, a further experiment is required to understand the mode of action of silica in inducing plant resistance to the pathogen.

AbstractPotato cultivation in Indonesia is mostly carried out in upper land with steep slope that also contribute a significant portion in annual volume of eroded soil. Hydroponic system could be an effective method for potato cultivation while avoiding soil erosion. The objective of this research was to design a hydroponic system for potato cultivation. Computational Fluid Dynamic (CFD) simulation was used to describe the root zone temperature distribution in a hydroponic bed. Potatoes was grown in hydroponic systems with different treatment of Electrical Conductivity (EC) values of nutrient solution, i.e. 1.8 mS and 2.5 mS. CFD simulation was capable to describe the distribution of fluid temperature inside the hydroponic bed accurately with R2 value of 0.9837 and average error of 1.8%. Potato plants grown in hydroponic system performed well. It produced tubers although the root zone temperatures reached 30.4°C. Plants grown at EC value of nutrient solution 1.8 mS treatment produce the average number of tuber 4.3 tubers and average weight of tubers 77.2 g per plant. While that grown at nutrient solution with EC value of 2.5 mS produced the average number of tuber 4.6 tubers and average weight of tubers 60.0 g per plant. It was demonstrated that the hydroponic system could be used in potato cultivation for consumption tuber.AbstrakBudidaya kentang di Indonesia umumnya dilakukan pada lahan miring di dataran tinggi sehingga memberikan kontribusi yang signifikan terhadap erosi tanah.

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.

Buncis tegak (Phaseolus vulgaris L.) memiliki potensi dibudidayakan pada dataran rendah dengan kondisi suhu yang lebih tinggi. Pemberian naungan diharapkan dapat menurunkan suhu lingkungan tetapi informasi dampak morfo-anatomi pada daun buncis ternaungi masih terbatas. Tujuan penelitian adalah memperoleh informasi karakter daun buncis tegak sebagai respon adaptasi intensitas cahaya rendah. Lokasi Penelitian di Kebun Percobaan Pusat Kajian Hortikultura Tropika IPB, ketinggian lokasi 250 m dpl, dilaksanakan pada bulan Oktober 2019 sampai dengan Januari 2020. Desain percobaan Rancangan Petak Tersarang dua faktor empat ulangan. Faktor pertama net dengan intensitas menahan cahaya 25%, dan 50%, serta tanpa naungan (0%) sebagai kontrol. Faktor kedua yaitu buncis tegak varietas Balitsa 2, Balitsa 3, dan buncis rambat Lebat 3 sebagai pembanding. Hasil menunjukkan bahwa dengan menurunnya intensitas cahaya, maka luas daun meningkat, tebal daun dan tebal palisade menurun, jumlah stomata dan kerapatan stomata menurun. Hasil analisis pigmen menunjukkan daun buncis yang mendapat intensitas cahaya rendah cenderung beradaptasi untuk mengefisiensikan penangkapan cahaya dengan meningkatkan jumlah klorofil a, klorofil b, total kloroil, dan menurunkan nisbah klorofil a/b daun. Sedangkan pembentukan antosianin di bawah naungan menurunkan kemampuan efisiensi penangkapan cahaya.

Cauliflower is one the important vegetable crop in the tropics; the curd contains high fibres, potassium, carotene and vitamin C. However, the production and productivity of cauliflower in Indonesia has been low and cannot meet the demand, resulting in high importation of cauliflowers into Indonesia. Bogor Agricultural University has developed potential lowland cauliflower genotypes, BOB017 and BOB020, with higher productivity. In this study, we evaluated three fertigation methods on the growth, yield and economic returns of the two lowland cauliflower genotypes. The experiment was arranged in a split-plot design with four replications. The main plot contained two cauliflower genotypes, BOB017 and BOB020. The subplot was three fertilizer application methods: through drip irrigation, soil drench, and drilled. The results showed that BOB020 had an earlier harvest time (60 days) compared to BOB017 (71 days). The soil drench fertigation method showed the highest curd weight (351.64 g), curd diameter (14.65 cm) and yield (12.39 t.ha-1) compared to the other two fertigation methods. The BOB017 genotype fertilized with soil drench method resulted in the highest B/C ratio (3.32). The study concluded that growing cauliflower using the soil drench method resulted in the optimum growth of cauliflower, high yield and net income.

Spray hose is a micro-irrigation system using perforated hose as for micro irrigation. Shallot conventional cultivation requires lots of water and labor man days therefore is more efficient. Shallot cultivation system needs to be developed to increase yield and to reduce production cost. This research was conducted to compare conventional cultivation methods with using Spray hose and polyethylene mulch for shallot production. This research was conducted in a hydromorphic alluvial soil type at the Center for Tropical Horticulture Studies Field Station in Kersana, Brebes, Central Java (S 6 o, 55’, 20.536”; E 108o, 51”, 50618”) from May to July 2016. The experiment was arranged in a randomized complete block design (RCBD) with a single factor and three levels of planting system, i.e. conventional ‘Surjan’ system without mulch, one line spray hose with mulch, and two lines spray hose with mulch, with five replications. The result showed that shallots production using of polyethylene mulch and two-line spray hose had higher yields than the conventional method. In addition, this system is more efficient in terms of labor requirement. Cost Revenue Analysis shows that conventional cultivation R/C ratio was 1.72, one-line spray hose R/C ratio was 1.92, while two-line spray hose was 2.26. This study demonstrated that the use of polyethylene mulch combined with two-line spray hose significantly improved shallot growth and increased bulb production, and more cost efficient.Keywords: R/C ratio, micro irrigation, labor, ‘Surjan’ system, soil drench, fertilizerConclusionIrrigation of shallot with two-line spray hose resulted in a better crop growth and a higher yield than conventional planting system and one-line spray hose for polyethylene mulched shallot. Conventional planting system using more water and labor requirement than the two other treatments. Combination of two-line spray hose and polyethylene mulch had the most eficient cost production of shalot compared to the conventional system and one-line spray hose.

Publisher : Department of Agronomy and Horticulture, IPB University

Fruits and young shoot of Solanum nigrum Linn are harvested and consumed as indigenous vegetables by different Indonesian ethnics. Preharvest factors and harvesting methods to maximize the quality of S. nigrum produce is still unknown. In this study S. nigrum was grown in full irradiance and under shading and assessed for their growth, and fruit and shoot yields. The experiment was conducted at the Leuwikopo Experimental Farm in Bogor Agricultural University, Indonesia from April-July 2017. The results demonstrated that plants produced more fruits and shoots in full irradiance, i.e., 687.9 g and 211.1 g per plant, whereas only 331.1 g and 116.9 g per plant were produced in 50% shading. Although fruit and shoot production were superior under full irradiance, shoot-harvested plants had healthier leaves and life span of about 2 months longer thus facilitating longer availability. Canopy of shoot-harvested plants formed a columnar shape with 23 to 45 cm in height, in contrast to spherical shape with 48 to 203 cm in height of the fruit-harvested plants. It is likely that shading level might contribute to farmers’ decision to harvest the shoots or fruits of S. nigrum. Further studies are needed to determine the effects of shading levels on nutritional quality of the shoots and fruits of S. nigrum.

Background: The use of limes is increasingly widespread worldwide, both as fresh fruit for consumption and for making juice or other drinks. Lime is also used in making jams and candies. The essential oil obtained from the skin is widely used in the pharmaceutical and cosmetic industries for medicines, perfumes, soaps, body lotions, and detergents. However, during fruit storage, the respiration and metabolic activity in lime fruits is directly related to the increase in ambient temperature, which makes the fruit dry out. Improving the shelf life of lime against post-harvest stress while maintaining the sensory and nutritional qualities of fresh produce can be achieved through low-temperature storage and the use of packaging. This study aims to improve the quality of lime by knowing the difference between the provision of packaging and not-given packaging combined with different storage temperatures. Method: The experimental design used a single-factor completely randomized design with storage type treatment, which includes room temperature without packaging (control), room temperature with packaging, low temperature without packaging, and low temperature with packaging. Observations of non-destructive characteristics include weight loss, respiration rate, and fruit peel color. Observations of destructive characteristics include juice content, fruit peel softness, Soluble Solid Contents (SSC), Total Acidity (TA), SSC/TA ratio, and ascorbic acid content. Findings: Low temperature treatment without packaging provides the best results in delaying weight loss, respiration rate, and SSC/TA ratio. The control treatment provided the best results for peel softness, juice content, and ascorbic acid. Conclusion: Low temperature treatment without packaging is recommended for the storage of lime fruit to extend its shelf life. Novelty/Originality of this Study: This study examines the combined effects of low temperature and newspaper packaging on extending the shelf life of lime fruits, addressing a significant gap in postharvest storage research for non-climacteric fruits such as lime.
