Agronomic practices in Indonesia mostly still use ammonium as the primary source of nitrogen (N), whereas ammonium concentrations at certain levels can cause plant toxicity. The selection of the suitable N form (NH4+ and NO3-), especially by the fertigation method, is expected to increase the efficiency of N fertilization. This research aimed to obtain the appropriate source of NH4+ and NO3- to increase production and efficiency of fertilization in shallots. The experiment used a non-factorial randomized complete block design with four replications and six nitrogen treatments: without N, ammonium sources (urea, ZA), nitrate source (calcium nitrate), and combination of ammonium and nitrate (NPK Mutiara 16-16-16, calcium ammonium nitrate). The fertilizer doses contain N in equivalent levels, i.e., 167.9 kg N ha-1. The results showed that ZA increased the chlorophyll content of leaves and N content of plant tissue, while calcium nitrate increased the size and weight (fresh and dry) of bulb per plant. The highest recovery and agronomy efficiency was obtained in the ZA application, while the highest physiological efficiency and partial factor productivity were in calcium nitrate. Therefore, nitrate has the potential for shallot cultivation because it can increase production without accumulation in the bulbs.

Deep sea water (DSW) has the potential characteristics for nutrient supplement in hydroponics cultivation. This experiment was carried out to evaluate the application of DSW as a nutrient supplement for tomato cultivation in hydroponics system. Tomatoes were grown on 4 beds in nutrient film technique (NFT) system circulated with 1.5 dS m-1(control), 10 dS m-1 15 dS m-1 and 20 dS m-1 of nutrient solution, respectively. DSW was supplemented into nutrient solution of control to obtain high EC level. Fresh weight of fruits decreased varied from 10-20% by increasing DSW concentration in nutrient solution, but the effect of the treatment was not found on size of 3rd truss fruits. The density of fruits increased as the DSW concentration increased in nutrient solution. Tomato stiffness of treated plants had almost the same value among EC levels although different among 3 trusses. Fruit quality parameters increased by increasing the DSW concentration in nutrient solution. Treated plants circulated with EC 20 dS m-1 supplemented nutrient solution for 2 weeks produced tomatoes with highest soluble solids, 8.0% Brix or increased 30% of control (1st truss). However there were no significant effect on fruits of 2nd and 3rd trusses. DSW could be used as nutrient supplement for hydroponics cultivation of tomato. Key words : Deep sea water, fruit quality, electrical conductivity, tomato

Chili peper (Capsicum annuum L.) var. Prabu was grown with polyethylene mulched and drip irrigation system on Andosol Sukamantri soil with low pH (4.5), low C-Organic (1.79%), low N-total (0.18%), high K content (0.76 me/100 g), and very high soil P2O5 concentration (190 ppm) to optimise fertilizer rate for drip irrigated and polyethylene mulched crop management system. This research was conducted from March - July 2004 at Danasworo Hydrogarden Ciapus Bogor. This research was arranged in Randomized Completely Block Design with four levels of fertilizer rate (0=control; 1x recommendation rate =151 kg N/ha, 69 kg P2O5/ha, 120 kg K2O/ha; 2x recommendation rate = 302 kg N/ha, 138 kg P2O5/ha, 240 kg K2O/ha; 3x recommendation rate = 453 kg N/ha, 207 kg P2O5/ha, 360 kg K2O/ha). Hundred percent of P, 50% N and K were applied pre-plant and 50% N and K were fertigated 10 times. The result showed that plant height and plant dry weight increased linearly with fertilizer application from 0 to 3x recommendation rate. Total marketable yield was quadratically increased with fertilizer application from 0 to 3x recommendation rate. Base on total marketable yield, optimum recommendation rate for chili with drip and polyethylene mulch were 237.07 Kg N/ha, 108.33 Kg P2O5/ha, and 188.4 Kg K2O/ha. Key words : Chili, fertilizer, drip irrigation, polyethylene mulch, fertigation

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.

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

Eggplant, yard long bean, and kangkong, were grown with polyethylene mulch with a drip irrigation system on Podzolic soil with low pH (4.5), low C-Organic (0.97%), very low total-N (0.17 %), low K content (0.15 me (100 g)-1), but had a high soil P2O5 concentration (13.7 ppm) to evaluate the best crop management practices under this soil condition. Combination of polyethylene mulch treatments (with and without), fertilizer (with and without), number of irrigation lines (0, 1, and 2 lines), and methods of fertilizer applications (preplant, split, and drip) were arranged in a Randomized Completely Block Design with four replications. The results showed that the use of mulch and fertilizer signiﬁ cantly increased yield of all crops. One line irrigation system also resulted in the best yield. Preplanting application of 100% P, 50% N and K in addition to 50% N and K applied 10 times weekly was the best methods to produce Eggplant, Yard Long Bean, Kangkong under polyethylene mulched and drip irrigation system.

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

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 .

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 . Keywords: calibration, fertilizer recommendation, phosphorus, yard long bean
