Tanaman soba (Fagopyrum esculentum) berasal dari wilayah subtropis, berpotensi sebagai pangan fungsional karena mengandung senyawa flavonoid antioksidan yaitu rutin. Kadar rutin sangat dipengaruhi oleh lingkungan. Penelitian ini bertujuan untuk mengetahui potensi tanaman soba sebagai sumber bahan pangan fungsional. Penelitian dilaksanakan di Kebun Pembibitan, desa Kopo (600 meter dari permukaan laut) Kabupaten Bogor, Jawa Barat, dari bulan Mei sampai Juli 2012. Metode yang digunakan adalah rancangan petak tersarang dalam rancangan acak kelompok dua faktor dengan tiga ulangan. Faktor pertama adalah naungan terdiri dari dua taraf, yaitu: tanpa naungan, dengan naungan paranet 55 persen, dan faktor kedua adalah populasi terdiri dari dua taraf, yaitu: 200 tanaman/m2, 50 tanaman/m2. Hasil penelitian menunjukkan produksi biji terbanyak pada kombinasi perlakuan tanpa naungan populasi 200 tanaman/m2 (N0P1) sebesar 764,3 g/m2 atau 7,643 ton/hektar dan terendah pada perlakuan dengan naungan paranet 55 persen populasi 50 tanaman/m2 (N1P2) sebesar 146,0 g/m2 atau 1,46 ton/hektar. Kadar rutin tertinggi diperoleh pada perlakuan tanpa naungan sebesar 0,398 mg/g biji. Produktivitas kadarrutin biji soba sebesar 304,19 mg/m2. atau 3,04 kg/hektar.Buckwheat (Fagopyrum esculentum), originated from subtropical regions, has the potential as a functional food because it contains flavonoid, called rutin. Rutin concentration is greatly influenced by the environment. The objective of this study is to determine the potential of the buckwheat plant as a functional food. The research is conducted in the nursery garden of Kopo village (600 m asl), Bogor District, West Java, from May to July 2012. The method used is the nested plot design in a randomized complete block design with two factors and three replications. The first factor is two levels of shading namely without shading and with shading of 55 percent paranet. The second factor is two crop densities namely 200 plants/m2 and 50 plants/m2. The research results show that the highest grain production (764.3 g/m2 or 7.643 tons/ha) is in the combination treatment of NOP1 and the lowest one (146.0 g/m2 or 1.46 tons/ha) is in N1P2 treatment. The highest rutin concentration is obtained on the treatment without shade at 0.398 mg/g groats. The productivity of rutin concentration of buckwheat groats is 3.04 kg/ha.

One of factors affecting the productivity of soybean crop is the availability of solar radiation. Reduction of solar radiation reaching soybean crop by cloud cover especially during rainy season or by shade of trees could potentially decrease soybean production. The availability of radiation for the crop can be increased through the use of reflective mulch to reflect back transmitted radiation to the crop canopy. This study aimed to determine the effect of shade and reflective mulch on crop solar radiation balance and crop productivity responses. A field experiment in Bogor, Indonesia in July 2016 to January 2017, was conducted, applying a Nested Design-two factors model with three replications. The first factor was two levels of shading, i.e., without and with 50% shade; and the second factor was three levels, i.e., without mulch, black silver mulch, and metallic mulch. The results showed that the use of mulch influenced the radiation balance of plants, increasing distribution of radiation reception in plants, solar radiation interception and RUE. The use of mulch caused changes in canopy structure by increase LAI, so that the inhibited radiation was higher. The reflected radiation from the mulch increased production per plants and weight of 1,000 seeds in shaded plants.Keywords: black silver mulch, metallic mulch, radiation balance, radiation interception, shading

Study on the effect of dose management on water irrigation and the effect of pruning corn lower leaves on productivity of Lamuru variety grown on dry land of dry climate area has been done. The experiment was organized at Naibonat Experimental Station, East Kupang Subdistrict, Kupang, East Nusa Tenggara, from June to October 2011. The area used was 72 × 32 m using split plot design methods, employing two treatments. The first treatment was conducted on the main plot with water irrigation dose given 100, 80, and 60% the dose control was according to the farmer’s customary. The second treatment was applied by pruning or not pruning the lower leaves at the generative phase on the determined submain plot. The result showed that dose of water irrigation of 80 and 60% gave significant effect on corn productivity, that is 7.3 and 5.3 ton/ha, but not significant to the control (6.6 ton/ha). On the other hand, the treatment with and without leaf pruning did not give significant effect on the growth component because pruning was conducted during the generative phase. The Anova test result of corn productivity was not significantly different between the treatment of with and without pruning. The treatment of 80% dose of water irrigation could save water until 842 m3 or 20% per planting season per hectare. Meanwhile, the farmer’s customary wasted the water up to 2.105 m3 or 50% per planting season per hectare. Based on the results, the optimizing of water irrigation interval is seven times more efficient in one planting period as compared to 14 irrigation times in one planting period.

A sweet corn model was developed to simulate the growth and development of hybrid-sweet corn under different crop denssities. This research is comparing the data of the simulation model and the actual observation data in the field, which is then presented in graphical form. This model was conducted on six treatment combinations between three types of spacing and two varieties. The simulation model requires meteorological data (average temperature, humidity, precipitation, and radiation), soil water data, and crop chracteristics. There are five of the six plant combinations which graph show that the model is able to simulate the total maize corn biomass every week. The model was able to estimate 93% of the actual biomass and described the growth and development of hybrid-sweet corn as well. Keywords: estimating biomass, models and simulations, plant growth

The primary host of sandalwood seeds (Santalum album L.) which is widely used in the nursery process is Alternanthera sp. However, the local name given to this primary host is same as that given to Portulaca sp. The same local name for these two-different species may cause mistakes in the use of the primary host during the cultivating process of sandalwood. Meanwhile, the ability of the Portulaca sp. as the primary host is unknown. Information about the right radiation intensity of the sandalwood seedling is still limited. The study aims to analyze the growth of sandalwood seedlings grown with primary host of Alternanthera sp. and Portulaca sp. at different radiation intensities. The completely randomized design with two treatments factor were used, namely differences in shade levels (without shade, 25, 50, and 75%) and differences in the types of primary hosts. The result showed that the primary hosts of Alternanthera sp. have the best growth for sandalwood seeds compared to sandalwood seedlings planted with Portulaca sp. The shading must be adjusted to the type of primary host. Sandalwood seeds grown with Alternanthera sp. as primary hosts grow best at 50% and 75% paranet shade conditions, in radiation range of 9.86–12.17 MJ/m2/day. Sandalwood seeds planted with Portulaca sp. as a primary host grow best in 25% paranet shade, that is at average radiation of 13.62 MJ/m2/day. The use of Alternanthera sp. and shade provision (50–75%) is highly recommended in sandalwood seedlings. Keywords: haustoria, hemiparasite, primary host plant, sandalwood, symbiosis

Sandalwood (Santalum album L.) seedlings planted with different primary host plants should require different amounts of water. In practice, however, sandalwood seedlings with different primary host plants are irrigated with similar amount of water. Thus, it is interesting to study the amount of water expressed as evapotranspiration for the sandalwood seedlings and their primary host plants because there are hemiparasitic symbiosis plants in one planting medium. The purpose of this research was to compare and analyse evapotranspiration (ET) and water use efficiency (WUE) of sandalwood seedlings with different primary host plants, namely chili (Capsicum annum), krokot (Alternanthera sp.), and sengon (Albizia chinensis). The experiment was conducted in a greenhouse and designed using completely randomized design. Results showed that different primary host plants already influenced ET at 6 days after sowing of primary host (DASH). The sandalwood seedlings with chili and krokot as primary hosts, had the highest ET during 6-22 DASH. From 24 to 36 DASH, ET for all types of host plants were similar. After 36 DASH, ET of sandalwood seeding with primary host sengon increased, and had the highest ET. Sandalwood seedling with primary host krokot had the highest WUE to produce sandalwood above ground biomass with value 0.3 g/l during the 0-3 weeks after sowing of primary host (WASH), 0.6 g/l during the 3-6 WASH, and 0.9 g/l during 6-9 WASH.

The city of Pagar Alam, South Sumatra is at an altitude of 600-2700 masl. The city has climatic and soil condition suitable for red chili plants (Capsicum annuum L.) that have high economic value. However, the fluctuating amount of red pepper production throughout the year can lead to excess or lack of availability of red chili in the market. This research was conducted to use a crop model to simulate the development, growth, and production of red pepper plant. This model used daily weather as input to simulate daily biomass (kg/ha) components of roots, stems, leaves, and fruits. Comparison of fruit components from simulation with field data taken at three areas in Pagar Alam city showed model accuracy of 76% for Koramil area, 91% for Perandonan area, and 85% Pagargading area. The simulation model result show that the average monthly chili productivity varies; highest of 3376 kg/ha if planting is done in October, and the lowest of 2828 kg/ha if planting is done in February.
