Organonitrofos is one type of organic fertilizer capable of providing macro nutrients that more than other organic fertilizers, particularly nitrogen and phosphorous from the compost of a mixture of fresh manure and rock phosphate using Microbial N2-fixer and P-solubilizer. Research purpose was to study the effect of organonitrophos combined with inorganic fertilizer on the growth, production, yield of sugarcane, and determining the most effective combination of agronomically and economically in up landsugarcane. Research consisted of 5 treatments with 3 replications arranged in a randomized complete block design. The treatment were A (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl), B (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl, 5,000 kg ha-1 Organonitrophos), C (150 kg ha-1 Urea, 75 kg ha-1 TSP, 150 kg ha-1 KCl, 10,000 kg ha-1 Organonitrophos), D (10,000 kg ha-1 Organonitrophos), and E (without fertilization). The results showed that the dose of fertilizer recommendation (300 kg ha-1 urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl) supplemented with 5 ton ha-1 Organonitrofos compared to the doses of fertilizer recommendation (300 kg ha-1 Urea, 150 TSP kg ha-1, 300 kg ha-1 KCl) was not significantly different on growth, yield, productivity of sugarcane and sugar. While the addition of 10 ton ha-1 Organonitrofos at half dose of recommendation (150 kg ha-1 urea, 75 kg ha-1 TSP, and 150 kg ha-1 KCl) produced 106.11 tons ha-1of sugarcane and 7, 95 ton ha-1sugar being lower than the dose of fertilizer recommendation that produced 133.02 tons ha-1sugarcane and 10.72 ton ha-1 sugar resulting macro nutrients derived from half dose of fertilizer recommendation are not able to increase the productivity of sugarcane and sugar.Dose of fertilizer recommendation plus 5 ton ha-1 Organonitrofos was an effective dose of fertilizer agronomically while fertilizer dosage recommendation was the most efficient dose of fertilizer economically.Keywords :dry land, fertilizer, inorganic, Organonitrophos, sugar cane

Laboratory bioassays were conducted to compare the effects of the leaf extract ofÃ‚Â Acalypha indicaÃ‚Â L. (Euphorbiaceae) with synthetic insect growth regulators (IGRs) triflumuron and buprofezin against Spodoptera litura (F.). The experiment was set up as a randomized complete block design (RCBD). The treatments were two concentrations ofÃ‚Â A. indica extracts 1000 and 2000 ppm, two concentrations ofÃ‚Â buprofezin 100 and 200 ppm, twoÃ‚Â concentrations of triflumuron 120 and 240 ppm and control. Each treatment was replicated three times. Second instar larva ofÃ‚Â S. lituraÃ‚Â were used for the bioassays.Ã‚Â Mortality and biological variables of treated and control larvae were recorded daily. The results indicated that the application of A. indica extractsÃ‚Â and synthetic IGRs (buprofezin & triflumuron) significantly caused the S. lituraÃ‚Â mortality throughout the experimental period. At first, the toxicity of triflumuron on larval S. litura was significantly higher compared to those of buprofezin and Acalypha indicaÃ‚Â leaf extract. However, at the end of experimental period all treatments caused high mortality on S. litura, and those all were significantly different from control. The treatments also caused abnorrmal growth in larval, pupal, and adult stages. While in the control, larvae molted into normal adults. The results indicated that the use of biorational control agents such as synthetic insect growth regulators (IGRs) and those based on naturally derived products such as botanical insecticides show promise as a potential tool in S. litura management programs.

Rampai tomato (Lycopersicon pimpinellifolium) is one important vegetable in Indonesia. The production of rampai tomato increases every year, indicating a good opportunity for the tomato in market. In the process of cultivation, fertilization is a very important aspect. Advances in technology have invented some importantagricultural inputsespecially for chemical fertilizers such as Urea, TSP, KCl, NPK, and others. Nowadays, small scaled farmers frequently face difficulty to get chemical fertilizers on market because ofeither scarcity or high price. This condition needs to be well anticipated. Reducing the use of chemical fertilizers by using organic fertilizers which isproduced from local and cheap natural resources is a somewhat promising solution.The organic fertilizer tested in this study is an alternative fertilizer called Organonitrofos. Organonitrofos fertilizer is made from 70-80% cow dung and 20-30% phosphate rock, in the previous research. Both the materials are locally available in Lampung. This fertilizer then needs to be tested to ensureits consistency on plant production. In this study, Organonitrofosfertilizerwas testedon rampai tomato plantsin pots (pot experiment).The study aimed (1) to test the Organonitrofos fertilizer on the response of rampai tomato plants in pots (2)reduce the useof chemicalfertilizersin the production oframpai tomatoplants.The pot experiment was conducted in the Integrated Field Laboratory of the Faculty of Agriculture University of Lampung on January - April 2012. The experiment used Completely Randomized Design (CR) with 7 treatment (7 combinations between chemical fertilizer and Organonitrofos), 4 replicates each. Data collected was analyzed by using ANOVA and followed by LSD. The variables observed were agronomic aspects (such as plant height, biomass, and production) and water consumption. The results showedthat,based on theplant responsevariablessuch asplant height, upper and biomasses, andcrop production, treatmentC(100% Organonitrofos with 5000 kg/ha dose) was significantly different and better from every other treatment. Based on the water consumption (evaporationand irrigation), all the treatments were not significantly different. However, the research showed that the use of 100% Organonitrofos fertilizer (5000 kg/ha); resulted in the highest water productivity (yield/water consumption). This research also showed that the use of chemical fertilizersbe could significantly reduced by using combination between chemical fertilizers and Organonitrofos. Keywords: Rampai tomato , fertilizer, organonitrofos, plants response.

Returning and addition of organic material to soil is a key to protecting the soil, plants, and the environment. A study aimed to elucidate the effect of residual biomass application on some indicators of soil physical properties, abundance of earthworms and soil microbial activities was conducted in Kebun Percobaan (KP) Natar, BPTP Lampung from February to July 2017. The treatments were three types of crops biomass residues, i.e., maize stover, rice straw, and soybean stover (fresh or compost). The dosage rates were 0, 2.5, 5.0, 7.5, and 10 t/ha. The treatments were arranged in a randomized block design with three replicates. Upland rice (Inpago 9 variety) was planted after two weeks application of biomass residues treatments. The results showed that application of crops biomass residues improved bulkdensity and significantly increased soil water content at the high dose of biomass residues (7.5 or 10 t/ha). The amount and weight of earthworms with added of compost biomass was significantly correlated with soil water content (r values 0.491 and 0.376, respectively). The dose of biomass residues had a significant effect on soil respiration that the highest soil respiration was obtained in maize compost biomass treatment (at 12 weeks observation) was 31.7 and rice straw compost (at 8 weeks observation) which was 30.19 mg/hour/m2 C-CO2.

The field and laboratory experimental studies were conducted to determine the phosphorus (P) adsorption behavior employing Langmuir Method and yield of sugarcane as affected by compost and inorganic fertilizer applications, and to determine the correlations between the Langmuir parameters and the availability of P in soil or harvested P by the sugarcane. Both field and lab experiments were arranged in a randomized block design, consisting of five treatments (A= 100% NPK, B=100% compost, C=100% NPK + 50% compost, D= 50% NPK + 100%, compost, and E= no fertilizer).Â Each treatment was replicated three times. Field and laboratory studies were carried out in the sugarcane field and in the Laboratory of Soil Science, the University of Lampung for Langmuir P studies, respectively. The results showed that the applications of 100% NPK plus 50% organic fertilizer, and 100% NPK resulted in the highest amount of available-P in the soil, the lowest maximum adsorption of P (Xm) and the lowest relative bonding energy of P (km); as well as the highest effect on the increase of sugarcane production. On the other hand, the treatments of no fertilizer and the 100% organic fertilizer resulted in the highest maximum adsorption of P (Xm) and the lowest sugar production. There were very significant negative correlations between the maximum adsorption of P (Xm) and soil P, harvested P by the sugarcane and stem biomass; while similar trend but no significant correlations between the relative bonding energy of P (km) and soil P, harvested P, leaf biomass and stem biomass were detected.Â Â

The extraction methods using Bray P-1, Mehlich-1, and Olsen solutions are the most frequently used in equilibrium condition to estimate the available P in the soil constituents. However, each method can gives some different values that may not describe the availability of soil P. Therefore, it is necessary to conduct a laboratory experiment to compare the three solutions in equilibrium and kinetics conditions for P release from soil colloids as a basic data for the future related to plant productions. The objective of this study was to compare the amounts of P release in equilibrium and kinetics conditions using Bray P-1, Mehlich-1, and Olsen solutions and the rate constants (k) of P release from soil colloids using the three solutions of five soil constituents or treatments: (1) Soil (100% soil), (2) P-rock (100% phosphate rock), (3) compost (100% chicken manure compost), (4) soil + P-rock (75% soil + 25% phosphate rock), and (5) soil + P-rock + compost (50% soil + 25% phosphate rock + 25% chicken manure compost). Each extraction for each treatment was conducted in triplicate. The results indicate that the amounts of extracted P employing equilibrium condition in all treatments are significantly lower compared to those employing kinetics condition. The results also show that Mehlich-1 solution is the most powerful solution to extract P from soil constituents followed by Bray P-1 solution and Olsen solution, except that in the soil + phosphate rock + compost treatment in which the amount of P extracted using Mehlich-1 solution is the highest then followed by that of P extracted by Olsen solution and Bray P-1 solution both in equilibrium and kinetic conditions. The highest rate constants (k) of the reaction in all treatments were found in the extractions using Mehlich-1 solution for desorbed P followed by that of using Bray P-1 solution and Olsen solution.Â Keywords: Compost, equilibrium, kinetics, P extraction solutions, phosphate rock, soil
