Abstract

The objective of this study was to find out the effect of volume and source of growth media and lettuce growth and yield in Deep Pool Growing System (DPGS). The study was conducted from September to December 2003 at Deep Pool Growing System facility, Danasworo Hydro - Garden Ciapus, Bogor. The Study was arranged in randomized completely block design with two factors. First factor was volume of growth media ( 20 cm³ and 110 cm³). The second factor was source of growth media (synthetic foam, cocodust, rice-husk + OSF and rice-husk + cocodust). Medium volume of  20 cm³ with rockwool was used as a check. Nutrient compotion of the solution was as follows (ppm): Ca 117, Mg 24, K 210, NH4 25, NO3 233, SO4 113, and PO4 60, Fe 2.14, B 1.2, Zn 0.26, Cu 0.048, Mn 0.18, and Mo 0.046. Medium volume of 20 cm³ with synthetic foam obtained the best yield for all parameters. Therefore, this treatment could replace rockwool as medium for lettuce production in DPGS.   Key words : Deep Pool Growing System, hydroponics, growth medium

Abstract

Tomato (Lycopersicon esculentum L.) was grown with polyethylene mulch and drip irrigation on a Millhopper fine sandy soil testing very high in P and low in organic matter during two seasons to evaluate the effect of S source, rate, and application methods on plant growth and yield of fruit.  Sulfur rate of 34 and 68 kg S.ha-1 were applied with  preplant (broadcast in the bed), drip (10 weekly drip application), and  by split applications (50% preplant and 50% drip).  In split applications, S sources evaluated were ammonium sulfate and ammonium thiosulfate.  Plant height was increased with S application from 0 to 68 kg S.ha-1 in both studies. However, response on plant dry weight only occurred in spring 1999. Total marketable yield was 17.9 tons.ha-1 with 0 kg S.ha-1 and was increased linearly to 48.1 tons.ha-1 with application of 68 kg S.ha-1 in Spring 1999, but no response to S was obtained in the Spring 1998 study. Measured variables were not affected by S source and methods of application.  Increasing S application from 0  to 68 kg S.ha-1 reduced leaf and plant tissue P concentration 14 and 12% at mid season, 26 and 25% at  late season sampling times, respectively.  S application of 68 kg S.ha-1 reduced soil pH approximately 0.3 unit at the end of the season in both studies.   Key  words:  drip irrigation, sulfur,  fertigation, Lycopersicon esculentum

Abstract

ABSTRAKPemberian larutan KNO3 diduga dapat meningkatkan produktivitas tanaman iles-iles (Amorphophallus muelleriBlume). Penelitian bertujuan mempelajari pengaruh pemberian larutan KNO terhadap produktivitas A. muelleri. Umbiutuh umur satu tahun dengan bobot 100-125 g ditanam dalam polibag yang ditempatkan di bawah naungan paranet 50%pada musim hujan (September 2010-April 2011) di Bogor, Indonesia. Lima taraf larutan KNO3 yaitu 0, 2, 4, 6 dan 8% (b/v)diberikan melalui daun dan melalui tanah. Larutan diberikan 2 kali sebulan mulai 12 minggu setelah tanam (MST). Hasilmenunjukkan bahwa pemberian KNO3-13 nyata mempengaruhi pertumbuhan tanaman, khususnya meningkatkan jumlah daundan memperpanjang masa vegetatif. Pemberian KNO pada taraf 4% memberikan pengaruh tertinggi jika diberikan melaluidaun. Pemberian KNO33 taraf 4% memberikan pertumbuhan yang lebih tinggi jika diberikan melalui daun dibandingkanmelalui tanah. Secara umum, tidak ada pengaruh nyata pada pertumbuhan tanaman akibat pemberian dosis KNO yangdiberikan melalui tanah. Penelitian berimplikasi bahwa pemberian pupuk KNO melalui daun pada taraf 4% dapatditingkatkan efektivitasnya jika kerusakan pada anak daun dapat diminimalkan. Kerusakan daun cenderung meningkat padadaun tua, oleh karena itu, studi lanjut perlu dilakukan terkait waktu aplikasi yang tepat.Kata kunci: iles-iles, kalium nitrat, pupuk daun, pertumbuhan vegetatif

Abstract

ABSTRACTFertilizer application in elephant foot yams (Amorphophallus paeoniifolius (Dennst.) Nicolson) intercropping system is rare in Indonesia, therefore, NPK fertilizers experiment was conducted under the shade of 10-year-old coffee plantation at Leuwikopo Experimental Farm, Bogor, Indonesia, in order to increase the productivity of elephant foot yam intercropped with coffee trees. Prior to planting, 20 ton ha-1 of goat manure was applied. Four NPK combinations, i.e., N, P2O5, K2O at the rate of 0, 0 and 0; 100, 60 and 80; 125, 60 and 100; and 150, 60 and 120 kg ha-1, were applied. Results showed that there were no significant differences in leaf number per plant, petiole size and rachis length among treatments. Application of NPK decreased photosynthetic rates, while increasing rate of N and K2O had no effect on photosynthetic rates. NPK application at the 100 N, 60 P2O5 and 80 K2O kg ha-1 (N100P60K80 treatment) or larger prolonged growth duration regardless of NPK levels, and there was a close relationship between corm yield and growth duration. As a result, corm fresh mass was higher in the 100:60:80 kg ha-1 treatment than in control. In the N125P60K100 and N150P60K120 kg ha-1 treatments, leaves were damaged by heavy rains and winds, counteracting beneficial effect of NPK on growth duration and corm yield. These results suggested the importance of delay of entering dormancy for an increase in productivity of A. paeoniifolius.Keywords: NPK fertilizers, photosynthesis, productivity, prolong growth, tuber crop

Abstract

ABSTRACTKenikir (Cosmos caudatus Kunth.) is an Indonesian indigenous vegetable which is potential to be developed. Exploration conducted in Bogor, Sukabumi, Bandung, Bandung Barat, Subang, Garut, Majalengka, Kuningan, and Tasikmalaya had succesfully collected 20 accessions of Cosmos sp. The objectives of this study were  to observe similarity and estimate the yield of Cosmos accessions from West Java. Clusters analysis grouped 20 Cosmos accessions into three clusters. Cluster I consisted of Pendeuy, Saribakti, Karang agung, Sindangbarang, Langensari, Perbawati, Sudajaya girang, Karang tengah, Argalingga, Warnasari, Sukaresmi, Ciwidey, Jalan cagak, Lebaksiuh, Tugu selatan, Ciwarak, Linggarjati and Babakan accessions. Cluster II and III consisted only one accession each which were Ciaruteun and Dramaga, respectively. Seven accessions from different sub cluster were evaluated to estimate the yield. A significant variability was found among the accessions. Results showed that those accessions were significantly different on plant height, stem girth, numbers of primary branches, number of leaf, leaves width, leaves length, days to flowering and yield. The results showed that Dramaga and Ciaruteun acessions were recomended to be developed because of its high yield. Keywords: characterization, cluster analysis, exploration

Abstract

Chili pepper (Capsicum annuum L.) was grown with polyethylene mulched on Inceptisol soil with low pH (5.5), low organic-C (1.54%), very low total N (0.12%), low K content (0.29 me (100 g)-1), but very high soil P2O5 concentration (19.2 ppm) to evaluate the best crop management practices with starter solution. Seven starter solution combinations (1 = No Starter Solution + No CM + No SI, 2 = CM + SSVC, 3 = CM + SSG, 4 = SI + SSVC, 5 = SI + SSG, 6 = SI + CM+ SSVC, and 7 = SI + CM + SSG) were arranged in a randomized completely block design with four replications. Whereas CM = cow manure, SSVC = organic starter solution, SSG = inorganic starter solution, and SI=standard inorganic fertilizer. The results showed that inorganic, as well as organic, starter solution increased chili pepper growth and yield in less fertile soil. The highest marketable yield was obtained with application of standard inorganic (SI) + cow manure (CM) + inorganic starter solution (SSG). Inorganic starter solution application resulted in a better plant growth than organic starter solution, being evident at 1 week until 7 weeks after transplanting. However, inorganic starter solution did not signifi cantly increase total marketable yields. Application of cow manure, standard inorganic fertilizer, or addition of organic starter solution reduced total unmarketable yield, improved fruit qualities and increased marketable yield

Abstract

Potassium (K) is required in a large amount for plant growth and production of most fruit crops, including pineapple. However, excess application may decrease its growth and production. Therefore, fertilizer application must be site specifi c, based on soil nutrient status and plant requirements. The aims of the research were (1) to determine the soil K nutritional status of pineapple and (2) to determine the optimum dosage of K fertilization for pineapple grown in Sawah Baru, Darmaga, Bogor. The research was conducted using split plot randomized block design with fi ve soil K status as main plots i.e. 0, 70, 140, 210, and 280 kg K2O ha-1 representing status levels of very low, low, moderate, high, and very high, respectively. The sub plot was dosage of K fertilizer i.e. 0, 200, 400, 600, and 800 kg K2O ha-1. The result of the research showed that plant growth and production of pineapple were improved by soil K nutrient status and dosage of K application. The level of soil K nutrient availability was classifi ed into low (<14 ppm K2O), medium (14-50 ppm K2O), and high (>50 ppm K2O). Potassium fertilizer is recommended for the soil with low soil K status of 634 kg K2O ha-1 .

Abstract

Yard long bean (Vigna unguilata L.) 777 was grown in Ultisols, which typically have low pH and high P-fixation, to determine the best correlation of soil extraction methods for soil P with yields, and to develop soil P response categories. The research was conducted at SANREM base camp in Hambaro Village, Nanggung, Bogor, Indonesia from April to August 2008. Treatments were arranged in a Split Plot Design with three replications. The main plots were treatments with soil P status of 0X, ¼X, ½X, ¾X and X, where is X = 1,590.5 kg SP-36 ha-1 (36% P2 O5 ) applied once a month before planting. The subplots were P application rate of 0, 75, 150, 225 and 300 kg P2 O5 ha-1. Yard long beans were planted in double rows per bed, 60 cm between rows and 25 cm within rows, 2 seeds per hole, with plot size of 1.5 m x 5 m. Coefficient correlation (r) of extraction reagents Olsen, Bray-1, HCl 25%, and Mechlich-1 were 0.772, 0.765, 0.755, and 0.732, respectively. Based on Olsen soil testing methods, soil response categories of very low, low, medium, and high were (ppm P2 O5 ) ≤ 18.40, 18.40 < P < 117.27, 117.27 < P < 267.04, and ≥ 267.04 extracted-P, respectively. Based on Bray-1 soil testing methods, soil response categories for low, medium, and high were ≤ 87.81, 87.81 < P < 233.78, and ≥ 233.78 extracted-P (ppm P2 O5 ), respectively. Fertilizer recommendation based on the Olsen soil test for low response category was 185.75 kg P2 O5 ha-1, and for the medium soil category was 175.97 kg P2 O5 ha-1. The Bray-1 soil test for the low response category was 184.31 kg P2 O5 ha-1 , and for the medium soil category was 161.39 kg P2 O5 ha-1 .
