Abstract

Agricultural activities contribute  to the gases change  in the air affecting  adverse weather change, but on the other hand, it also cause the air reduction  provides a profitable bioenergy. To learn these circumstances it is necessary to analyze the source and sink mainly CH4 and CO2. the scale of the analysis carried out within the wider administrative area so the results can be considered a basic policy.  The results of analysis in  East  Java  showed that CH4 emissions from rice fields since 2000 to 2010 has  increased  from 2,310,728 to 3,157,010 tons. At the same time, the rice field was able to reduce 51,902,504 tons and  70,916,580 tons  CO2. The complexity of human activities and other gases in the air expect to result in weather changes which is  indicated by rainfall increasing during the last decade.

Abstract

The objectives of this research are  to study relations between IPM technology  pesticide use. The factors is education level, age, experience level and economic level of the farmers. This research is corelational research with an ex-post facto approach. The data were taken from 150 farmers that have been participate in FFS-IPM and 20 farmers non-FFS-IPM as a control. The data were tabulated by using frequency tabulation and analyzed by path analysis.The data that have taken and desciptive analyzed show that: (1) the level of knowledge on IPM and adoption for IPM of whole respondent FFS-IPM farmers is in low category (100%), furthermore the attitude toward IPM for the greater part of respondent of  FFS-IPM farmers is in medium category (92%). (2) the level of  pesticide use for the greater part of respondent of  FFS-IPM farmers is in low category (47,3%), while for the greater part of respondent of non FFS-IPM farmers is in high category (70%).Results of path analysis show that level of knowledge on IPM, economic farmers, and adoption rate of IPM have simultaneous and significantly effect on level of  pesticide use with contribution on 51,8%.

Abstract

The research was conducted to examine 2,4-D hormone on callus induction and the synthesis of alkaloids in Jarak (Jatropha curcas  L.) leaves callus on MS medium. The young leaves of Jarak are used as explant. The amount of 2,4-D hormone to be treated was 1 mg/l, 2  mg/l,  dan  3  mg/l, respectively.Evaluation of callus formation was done after 8 weeks incubation time. Qualitative analysis on the Alkaloid was done by color reaction and by TLC (Tin Layer Chromatoghraphy) with stationary phase silica gel GF 254 and asetat:metanol:air  (100:13,5:10) as movement phase. The chromatogram was observed under UV254 nm and UV366 nm lampsThe results showed 3 ppm concentration of 2,4-D hormone resulted highest growth of  callus formation (85%), the fastest time of callus induction (12.2 days) and average weight (0.054 grams) of dried callus. SimakBaca secara fonetikThe qualitative  analysis  with  Dragendorff  reagent  produced  positive  result  brown color in TLC  at UV254 nm, and  blue  color  in UV366 nm. hRf value was almost the same as wild type. According to the research, alkaloid also found in the callus as in the wild type plant.

Abstract

Helicoverpa armigera Hubner is an insect pest of corn and cotton crops. Eggs are laid by  H. armigera imago on corn silk and cotton crops often have high mortality, mainly caused by egg parasitoid. H. armigera egg on various agroecosystem reported can  be parasited by at least 12 species of  Trichogrammatidae. The purpose of this study was to determine the diversity of  Trichogrammatidae family as  parasitoid eggs of  H. armigera on  low population. H. armigera egg sample taken from Asembagus, Lamongan and Blora at 1 m2 field  both monoculture and intercropping. Observation of parasitoids and predators  done at the Laboratory of Biological Control Balittas Malang. Parasitoid that appears preserved in the Hoyer medium for identification purposes. low population of  H. armigera Egg in Asembagus is  4 eggs/m2 in both monoculture maize and intercropping with 86-100 days after transplanting (DAT) cotton and  4.5 egg/m2 on cotton monoculture and intercropping with 75  DAT soybean, while 2 eggs/m2 in the Lamongan and Blora corn agroecosystem. The dominant egg parasitoid in Asembagus is T. chilotraea, as well as in Lamongan and Blora.

Abstract

This study aims to determine the anti-termite potency of agricultural waste material that has not been used optimally, such as root and stem bark of tobacco and snackfruit rind to increase its economic value. The research conducted at the Laboratory of Agricultural Faculty Agroekoteknologi Trunojoyo. The study was designed based on completely randomized design (CRD) with 3 replication. The observation parameter is the number of termite mortality and weight reduction in test paper which is used as termite bait.  The results showed that the extract of root and stem bark Madura tobacco and snackfruit rind cause termite mortality was not significantly different ie consecutive 77.3% and 81.3% classified as strong termite. During the activity test, there is no weight reduction test paper so that termite mortality effect could be due to toxic effects of extract contacts.

Abstract

This research aims to study the effect of combined aplication Arbuscular Mycorrhiza (AM) and Urea to the growth, productivity and quality of roselle plants (Hibiscus sabdariffa L.). The research was conducted at the experimental garden and the Laboratory of Agroecotechnology Department, Faculty of Agriculture, University of Trunojoyo. The study consist of six treatment combinations, repeated 3 times, and based on randomized block design. The observation parameters includes the growth, production and quality of leaf and flower. ANOVA showed that there is no significant effect of combination of AMF and urea on growth parameters, productivity and leaf quality observations, but the real impact on the quality of flowers. Aplication of urea up to 50 kg / ha is still giving the highest effect on growth, plant productivity, vitamine C and protein rosella flowers but decreased the content of vitamin C and protein of leaves. Aplication of AM up to 5 g / plant had the same pattern with the aplication of urea.

Abstract

This study aimed to obtain information about physical and chemical characteristics of the peat due to addition of ash ameliorant with different dosage to get the best growth media. Ameliorant materials are litter ash / vegetation result of peatlands clearance, rice husk ash and palm bunch ash. This study used split plot design consists of two factors, ameliorant factor (A) as main plots, with 4 levels (a1 = litter ash / vegetation result of peatlands clearance, a2 = rice husk ash, a3 = trapalm bunch ash), and ameliorant dose (D) with 5 levels (d0 = no ameliorant / control, d1 = 50 g ameliorant, d2 = 100 g ameliorant, d3 = 150 g ameliorant, D4 = 200 g ameliorant / tube of peat), treatment was repeated three times and consisted of two samples, so there are 90 units of treatment. Observations were done on the weight of the content (bulk density), density of type (particle density), total soil pore space, nutrient levels of N-total, P, K, Mg, and pH of soil. The results showed that the addition of ameliorant material significantly improve the availability of P, K, Mg, and pH of the soil, but decrease N concentration of peat. Peat soil treated palm bunch ash has a greater density lindak with total soil pore space smaller than the peat treated litter ash/ vegetation peat and rice husk ash.

Abstract

Tomato is vegetable that has high economic and nutritional value. Hydroponics is the cultivation of plants without soil but using rice husk charcoal, rockwool, pumice, sand, gravel, perlite water and air media. This research aims to study the effect of nutrients and polybag size on growth and yield of hydroponic tomatoes. The experiment was conducted in Kassa House of Agroekoteknologi Departement Faculty of Agriculture Trunojoyo University. Fertilizers used were Hidrogroup and Greentonik while polybag size are 30x30 cm, 30x40 cm and 40x40 cm. The design of this study using Complete Randomized Design (CRD) with 3 replications. The result showed that this research affect to the vegetative phase. No interaction between type of nutrition and polybag size on plant height, leaf number, stem diameter, number of flowers, flowering time of tomato. Type of nutrition significantly affect plant height, leaf number, stem diameter, flower number and wet and dry weight of stems and leaves, whereas the size of polybags significantly affects in the number of leaves, wet and dry weight of stems and leaves of tomato.
