Increased Rice Crop Productivity Through Compost and NPK Fertilization. The aims of this research was to study response of compost and NPK fertilizers to the soil chemical properties and rice yield. The method used was a factorial Randomized Block Design consisting of two factors. The first factor was compost Fertilizer (B) consists of 2 levels, namely: B0 = Without compost fertilizer and B1 = 5 ton compost fertilizer ha-1. The second factors was NPK national recomendation (P) consists of 3 levels, namely: P1 = 50% of NPK recommendation, P2 = 100% of NPK recommendation and P3 = 150% of NPK recommendation. The results showed that the treatment of compost and NPK fertilizers gave no significant effect on tillers number clumb-1 and dry straw weight/m2 , but gave a significant effect on N, P, K and dry grain weight/m2. The combination of 5 tons of compost/ha and 150% of NPK recommendation can produce N-total, P-available level, K-available and dry grain weight per m2 respectively 0.35%, 13.79 ppm, 355, 21 ppm and 0.96 kg and significantly higher than the combination of 50% NPK recommendation and without compost, which were 0.26%, 8.21 ppm, 236.10 ppm and 0.69 kg respectively.

Ammonium Dynamics and Latosol Wetland Nitrates in Conventional Cultivation of Local and Hybrid Rice in Jatiluwih Subak. Plants absorb nitrogen in the form of ammonium (NH4+) and nitrate (NO3-). Each sample was analyzed for its ammonium and nitrate levels using macro Kjeldahl method. The results showed that the concentration of ammonium and nitrate in soil of the two rice fields were similar. The ions contents were as following: nitrate (2,67%) and ammonium (2,67%) in local rice, while those in hybrid rice fields were amounted of 1,48% and 4,59% respectivelly. The concentration of ammonium and nitrate on 21 DAC in soil samples remained low and rose at 28 DAC, then decreased at 56 DAC. It means that the times of fertilizing always done by the farmers were not appropriate.The content of ammonium and nitrate in water phase much lower than that in soils for both types of rice plants. The highest concentration of ammonium in local rice fields was 0,093% at the time of tillage and the lowest 0% on 21 DAC, while the highest nitrate concentrations in local rice water was 0,37% at 70 DAC and the lowest was 0% at of 21 DAC. The highest ammonium concentrations in hybrid rice 0,33% at 14 DAC, and the lowest 0% at 42 HST, while the highest nitrate content 0,47% at 42 DAC and the lowest 0% at the time of tillage. The fertilizing times recommended based on the findings of this reaserch is at 10-15 DAC for both rice types and another subsquent fertilization on 60-65 DAC for local rice and 40-45 DAC in hybrid rice.

Laporan Baru tentang Distribusi Jamur Entomopatogenik Aschersonia sp. yang Menginfeksi Kutu Putih di Bali. Penelitian tentang distribusi jamur entomopatogenik Aschersonia sp. dilakukan untuk mengetahui persebaran Aschersonia yang menginfeksi kutu putih di seluruh Bali. Penelitian tersebut dilakukan di Kabupaten Gianyar, Bangli dan Buleleng pada centra perkebunan jeruk dimulai tahun 2014 sampai tahun 2018. Aschersonia pertama kali ditemukan pada tahun 2014 di Desa Sekaan Kintamani Bangli dan Desa Kerta Payangan Kabupaten Gianyar, dan pada tahun 2018 ditemukan di Desa Gobleg Sukasada Kabupaten Buleleng. Distribusi jamur tersebut ditemukan di dataran tinggi dan tidak ditemukan di dataran rendah. Hal ini sangat terkait dengan keadaan iklim terutama kelembaban dan suhu. Jamur Aschersonia sangat baik tumbuh pada suhu 20°C yang berada pada dataran tinggi.

The Effect of Providing Seaweed Liquid Organic Fertilizer (Sargassum sp) on The Growth and Production of Leaf Onion (Allium Fistusolum). Market demand for leaf onion has increased from year to year but the growth and production of leaf onion has not increased because the farmers always fertilize using chemical fertilizers. This study aims to determine the effect of seaweed liquid organic fertilizer on the growth and production of leaf onions. The study was conducted on a land area of 30m2 in Tulungrejo Village, Bumiaji, Batu - Malang. The experiment used CRD (Completely Randomized Design) with 5 treatments and 5 replications. The treatment carried out were without giving of seaweed liquid organic fertilizer on the leaves onion plant (P0), giving seaweed liquid organic fertilizer to the leaves onion plant with a concentration of 5 ml / liter (P1), 10 ml / liter (P2), 15 ml / liter (P3), and 20 ml / liter (P4). The parameters observed were plant height growth, growth in number of leaves and weight of harvesting leaf onion. Observation data were analyzed using analysis of variance level 5% and Duncan's advanced test at 5% level. The results showed that the application of seaweed liquid organic fertilizer had a significant effect on the growth of leaf onion plants and the production of onion leaf. On the growth of the number of leaves, the application of seaweed liquid organic fertilizer did not have a significantly effect on the leaf onion plants in the age of 63 days after planting.

Association of Fruit Flies (Bactrocera spp.) (Diptera: Tephritidae) and Their Parasitoid on Guava (Psidium guajava L.) Cultivated in Bali. The study on the association of fruit flies (Bactrocera spp.) (Diptera: Tephritidae) and their parasitoid on guava (Psidium guajava L.) cultivated in Bali was conduted in order to know the abundance, attacks percentage and the species of parasitoid associated on guava, cultivated in Bali. The sampling was done intentionally by taking attacked fruit in Musi Village, Buleleng Regency; Pelaga Village, Badung Regency; and Tiga Village, Bangli Regency. The results showed that 3 species of fruit flies were found, namely B. carambolae, B. papayae and B. albistrigata. The percentage and number of adult insect emergence in Musi Village were B. papayae (50.87% ; 2772 imago), B. carambolae (35.18% ; 1803 imago) and B. albistrigata (13.94% ; 741 imago). In Pelaga Village B. carambolae (61.31% ; 2864 imago) dominates and B. papayae only 38.69% and 1801 imago. B. carambolae is also found dominant in Tiga Village (59.08% ; 2303 imago) and B. papayae only 40.92% and 1603 imago. Percentage of damage to guava is 24.27% on average. There are three species of parasitoids found that are associated with fruit flies on guava in Bali, namely Fopius arisanus, Diachasmimorpha sp. and Opius sp. The average parasitic rate is 6.76%. The highest parasitic rate is in Musi Village, Buleleng while the lowest is in Tiga Village, Bangli.

The Effect of Soil Tillages Frequency and Compost Fertilizer on Soil Physical Properties and Corn Yields. The aims of this research is to determine of effect soil tillage frequency and compost fertilizer on soil physical properties and corn yields. The method was used a Randomized Block Design (RBD), factorial consisting of two factors, namely: Soil Tillages Frequency (T) consists of 3 levels, namely: T0 = no tillage; T1 = if one time and T2 = if twice. Compost Fertilizer (K) consists of 3 levels, namely: K0 = Without compost, K1 = 5 tons compost/ha and B2 = 10 tons compost/ha. Combination treatment into 9 treatments, namely T0K0 , T0K1, T0K2, T1K0, T1K1, T1K2, T2K0, T2K1, T2K2. and each treatment was repeated 3 times, so there were 27 research plots.The results showed that the soil tillage frequency and compost fertilizer had no significant effect on the soil physical properties and corn yields. Twice soil tillage frequency resulted bulk density, porosity, soil moisture content and dry corn yields respectively 1.01 g/cm3, 60.98%, 37.31% and 0.83 kg/m2, and not significant different compared with no tillage which is 1.03 g/cm3, 60.43%, 36.57% and 0.81 kg/m2. Addition of 10 tons compost/ha resulted bulk density, porosity, soil moisture content and dry corn yield respectively 0.99 g/cm3, 61.75%, 38.21% and 0.86 kg/m2, and not significant different compared with without compost fertilizer which is 1.06 g/cm3, 59.40%, 36.44% and 0.80 kg/m2.
