Maydis leaf blight disease caused by Bipolaris maydis can attack corn plants in the vegetative and generative phase and can reduce yield up to 70%. Biological control of plant diseases with the use of biopesticides alone or in combination with other botanical materials can be efficient because it is easy to obtain, cheaper price, also environmentally friendly. The objective of the study was to obtain a combination of B. subtilis formulation with a botanical pesticide which has the potential to control the growth and development of maydis leaf blight. In addition to this, we also observed the effect of the application of the combination of botanical pesticides and B. subtilis formulation on plant growth. The study was conducted on February till June 2016 at the Plant Pathology Laboratory of ICERI with a complete randomized design and the Bajeng Experimental Farm using a randomized block design. In vitro testing, the treatment with vegetable pesticide of clove leaf extract gave better results in suppressing B. maydis. Similarly, in field testing, the application of B. subtilis formulation combined with clove leaf extract also gave a better effect in suppressing the development of maydis leaf blight disease and increasing yield. Applications of B. subtilis formulation can suppress maydis leaf blight disease by up to 13% and potentially increase yield by 26%.

Implementation of soybean production technology of specific location with using high quality seeds of superior varieties is one of the important factors for achieving increased production of soybeans. This assessment was aimed to determine the effect of assembly seed production technology to yield, feasibility of seed breeding and viability. The experiment was conducted in lowland KP. Mojosari, Mojokerto regency which was held on dry season I 2013. Randomized experimental design with 6 replications in an area of 1.0 hectares was used in the experiment. The treatment consisted of five varieties, namely : (a) Anjasmoro, (b) Argomulyo, (c) Kaba, (d) Sinabung, and (e) Argomulyo (Farmer). Assessment of seed storage technology was conducted at Laboratory of Seed of AIAT East Java for 8. The result of study showed that the highest productivity was found in soybean medium seed type, namely Kaba varieties (2,41 t/ha of consumption seed and 1,96 t/ha labeled seed) and Sinabung (2,39 t/ha of consumption seed and 1,90 t/ha labeled seed) with each R/C value of 2,18 and 2,12 respectively, so that the seed breeding using the recommendation technology is economically feasible. The treatment of drying of large seed type (Anjasmoro and Argomulyo) and medium seed type (Kaba and Sinabung) had the viability > 80% with the retention period until the eighth month when the seeds are dried each 1 month with moisture content <10%. The cultivation technology and soybean storage Argomulyo way farmers without re-drying produce viability >80% which only occurs until the fourth month.

Soybean production at farmer level is still low, which ranges between 0.6-2.0 ton ha-1and average of 1.3 ton ha-1. Meanwhile, yield potential shows up to 3.0 ton ha-1. This big yield gap present an opportunity to increase yield through productivity approach, as well as other treatment including the use of inorganic and bio-fertilizers. An experimet has been executed to observe the production of 3 soybean varieties as affected by inorganic fertilizer and bio-fertilizer. The experiment was implemented at the Sugihan village, of the sub-district of Toroh, at Grobogan district, Central Java, in June â Sept 2014. The experiment was arranged in nested design with 2 factors, namely fertilization and variety, and in 3 replications. Three levels of fertilization were (1) Control (= Â½ Recommended dose, i.e.Urea (25 kg ha-1), SP-36 (50 kg ha-1), and KCl (50 kg ha-1), (2) Fertilizer A (= Control + F-1 Biofertilizer), and (3) Fertilizer B (=Control + commercial biofertilizer). Meanwhile, varieties of soybean used were Grobogan, Gema and Dering. The trials were implemented in 2 lands with different history, i.e. former land of rice plants that are subjected to site-specific nutrient fertilization (PHSL) and former land of rice plants with farmer treatment (Non-PHSL). The result showed that there is no significant difference caused by interaction between variety and fertilizer factors. Soybean variety was found to be main factor determining production level, while fertilizer treatment showed no significant effect on yield. The highest production (observed through square plot method) was found from Grobogan variety. Weight of 100 grain was identified as yield component with strongest correlation to soybean yield.Â

The impact of deltamethrin on natural enemies can be determined directly through contact and oral applications or indirectly through residues on plants. This research was aimed to determine the indirect impact of deltamethrin on the egg parasitoid of Anagrus nilaparvatae.Â The rice plants of Cisadane variety were infested with 10 gravid females of N. lugens. Deltamethrin was applied at two concentrations (12.5 and 6.25 ppm) and at 7, 3, 1 day and 3 hours before the parasitization. Deltamethrin residues on rice plants were decrease the number of Nilaparvata lugens, parasitoid andÂ parasitization level of A. nilaparvatae. This suggests that deltamethrin residue on rice plants could decrease the role of A. nilaparvatae in controlling N. lugens.

Site Spesific Nutrient Management/SSNM (Pemupukan Hara Spesifik Lokasi/PHSL)Â recommendation for rice can be obtained from the website of Indonesian Rice Consultation Service (http:/webapps.irri.org>lkp). This program was developed by International Rice Research Institutes (IRRI) in collaboration with Indonesian Agency for Agricultural Research and Development (IAARD). The objective of this study is to evaluate the PHSL recommendation forÂ rice through adaptive research approach. This research was conducted in two sites (Ngawi and Jember) during the dry season (April to July) 2014. Three fertilizer recommendations ware evaluated : (i) PHSL recommendation for hybrid rice (Mapan P05 variety), (ii) PHSL recommendation for inbred rice (Ciherang variety) and (iii) fertilizers practiced by farmer for inbred rice (Ciherang variety). PHSL recommendation whichÂ assessed from the website with the yield target of 8 t/ha for Ngawi was 200 kg/ha Phonska applied at 0-14 days after transplanting, 125 kg Urea/ha applied at 24-28 days after transplanting and 200 kg Urea/ha applied at 38-42 days after transplanting. For Jember, rate of Phonska was higher (250 kg/ha) while rate of Urea wasÂ same with Ngawi. The three fertilizer recommendations were applied by each farmer with 10 cooperator farmers as replications. The observations included soil analysis before conducting the research, fertilizers used by cooperator farmers, yield of rice and benefit analysis. Fertilizer used by 10 farmers in Ngawi showed : (i) 7 farmers applied fertilizers two times and only 3 farmers applied three times, (ii) all farmersÂ used organic fertilizer from 220 to 940 kg/ha, (iii) all farmers used Phonska fertilizer and applied two times, (iv) total of fertilizers applied ranged from 700 to 1,000 kg/ha. While total fertilizers of PHSL recommendation was only 475 kg/ha. The similar observations were observed in Jember, but all farmers applied fertilizers two times. Research results showed that compared to farmerâ€™s practice, PHSL recommendation saved 26.83 kg N/ha, 55.23 kg P2O5/ha and 36.05 kg K2O/ha in Ngawi. In Jember, PHSL recommendation did not save N but saved 34.2 kg/ha P2O5 and 16.6 kg K2O/ha. Yield of inbred rice with PHSL recommendation was not different, however, yield of hybrid riceÂ was higher to that of farmerâ€™s practice. It can be concluded that PHSL recommendationÂ save fertilizers with no yield decrease for inbred rice, or even, increased yield ofÂ hybrid riceÂ Itâ€™s means PHSL recommendation increase fertilizer-used efficiency and rice farming benefit.
