Abstract:Sheath blight disease, one of the most important diseases in rice, is caused by the fungus Rhizoctonia solani. The aim of the study was to find out the response of rice plant in different growth stages against R. solani infection. This research was performed during the dry and rainy seasons of 2017. The experiment used split plot design with four replications. The main plot was rice varietie (Ciherang, Minghui 63, and Hipa Jatim 2) and the sub plot was the inoculation times (maximum tillering, panicle initiation, flowering, and ripening). Rice cultivation wasperformed following the farmers practiceon 1000m2 areas devided by 60 experimental plots, 3m x 5m each. Data analysis and interpretation were performed using scatter chart and SAS 9.0. The results showed that sheath blight developed significantly and affected area under the disease progress curve (AUDPC) during maximum tillering (56,67% in dry season and 56,02% in rainy season) and panicle initiation stages (79,07% in dry season and 56,85% in rainy season). The larger the AUDPC the higher the decrease in the rice production.

Abstract:The opportunity to improve upland rice production on acid mineral soil is still high. However, the main problem of this soil is high soil acidity that inhibit crop growth, causing low production. The objective of this study was to evaluate the effects of agricultural waste biochar application on upland rice (Oryza sativa L.) productivity and improvement of acid mineral soil properties. The study was conducted at Agricultural Research Station of Tamanbogo, East Lampung on July-October 2013 (session 1), December 2013-April 2014 (session 2), May-August 2014 (session 3) and October 2014-February 2015 (session 4). The experimental design was split plot design, which the main plots were two types of biochar (cacao shell and rice husk), the sub plots were biochar rates (0; 5 t/ha and 15 t/ha) with five replications. The parameters measured were upland rice growth, yield and soil properties (Bulk density, soil pH and Al3+). The result showed that during the four planting seasons, the addition of cocoa shell biochar resulted better response on upland rice growth and yield compare to rice husk biochar, with crop yield of 2.54-3.97 t/ha dry grain. The dose of 5 and 15 t/ha biochar provided a stable yield and improvement of dry grain around 74.02-179.4% compare to no biochar addition for three consecutive sessions. The cocoa shell biochar applications showed better response on soil acidity (increase soil pH and reduce Al3+ ) and soil bulk density compared to rice husk. In degraded acid mineral soil, upland rice productivity and soil properties improvement can be increased by adding of 15 t/ha cacao shell biochar with a dose of 15 t / ha for getting dry grain more optimal.

Abstract:Cropping systems is one of the efforts to increase the yield of rice through the manipulation of plant spacing. Legowo rows is one of the methods in manipulating population to increase yield. However, high population with dense plants causes risk to fall when the rainy season. The purpose of this research is to know the effect of cropping system, seedling age, season on the growth and yield of Inpari 31. This research was conducted at Sukamandi for 2 seasons,in 2015 to 2016. Using a split-split plot design with the main plot of the season that is the dry season and the rainy season, planting system is sub plot with 3 levels : tegel, legowo 2:1, and 4:1. The age seedling is sub sub plot. The variable consisted tall of plant, number of tiller, and yield. The results showed that the age, plant spacing, season influenced the results significantly. The yield of age 20 DAS (day after sowing) higher than 30 DAS. During the dry season the yield was higher compared with the rainy season. In the dry season, the yield of legowo 2:1 was higher (7.69 tons/ha GKG) compared to legowo 4:1 and tegel (6.77 tons/ha GKG). However, the application of the planting system does not have a significant effect on increasing yieldsin rainy season.

Abstract:Maize Downy Mildew caused by pathogenic fungus of Peronosclerospora philippinensis is an important disease in centers of maize crops outside Java Island. Research on “The Appearance of Maize Downy Mildew Caused by Pathogenic Peronosclerospora philippinensis in Combination Treatment of Resistant Varieties and Metalaxyl Fungicide ” aimed to determine the effectiveness of a combination of fungicide treatment of active ingredients of metalaxyl with varieties that have resistance to Maize Downy Mildew which was caused by P.philippinensis species. This research was conducted at KP Bajeng (endemic area of Maize Downy Mildew of P. Philippinensis species), which was compiled in Separate Plot Design with 3 replications. The main plot contained 5 varieties of maize, namely: (1) Bima-3 Bantimurung, (2) Bima-20 URI, (3) Lagaligo, (4) Bima-15 Sayang, and (5) Anoman. On the other hand, the sub plot contained 5 levels of seeds treatment dose with Metalaxyl Fungicide Active Ingredient (0 g/kg, 2 g/kg, 3 g/kg, 5 g/kg, and 7 g/kg of maize seed). The results showed that the combination of resistant and susceptible varieties with Metalaxyl Active Ingredient at doses of 2g, 3g, 5g and 7g/kg of maize seed controlled the Maize Downy Mildew which was caused by the Peronosclerospora philippinensis species effectively. It was shown by the low reaction of Maize Downy Mildew infection, at the percentage of 0% -1,86%, respectively. Under the circumstances of susceptible varieties without Metalaxyl Active Ingredient treatment, the intensity of Maize Downy Mildew reached the percentage of 100%. The lower intensity was also followed by the production, cob length and weight of 1000 seeds that were higher than those of control treatment.

Abstract:Jajar Legowo Technology Super (Jarwo Super, JS) is an integrated rice cultivation technology on irrigated rice field based on jajar legowo 2:1 to improve rice yield by utilizing the influence of the border effect. Jajar legowo 2: 1 is difined as crops placement technique that every two rows of rice plants followed by one blank row and repeted for next rows). Part of the Jajar Legowo Super Technology component are: 1) New Superior Varieties (VUB); 2) bio-decomposer; 3) bio-fertilizers; 4) bio-pesticides and innorganic pesticides; and 5) agricultural equipment and machinery. The purpose of this study was to determine the technical feasibility, financial feasibility, and sensitivity performance of jarwo super technology (JS) rice farming at the farmer level compared to farmers who applied conventional rice cultivation or non-jarwo (NJS) technology. The research was carried out in three provencies in Sumatera such as: Aceh Province, North Sumatra and South Sumatra Province. Increased rice productivity in Aceh province is 31%, South Sumatra 37% and North Sumatra 12%. JS financial analysis of total revenue, allocation of JS cultivation cost is about 37.19% and NJS farmer 43.59%, with R/C ratio 2,69 for JS farmers, while for NJS R/C 2,29. Meanwhile, B/C ratio 1,69 for JS farmers and 1.29 for NJS farmers. The value of MBCR of introduced super jarwo technology is 5,25 which means the introduction of super jarwo technology is worth pursuing because with addition production costs of Rp 1 million can increase profits worth of Rp 5.25 million. According to BEP value the JS farmers will experience a loss if the decrease in yield is higher than 63% and the NJS farmers obtain lower tolerance with 56%. The results of sensitivity analysis with various scenarios showed that super jarwo farming still provides an adequate level of profit even though it tends to decrease.

Abstract:Abstrak Penelitian pengaruh pembenah tanah organomineral terhadap sifat kimia tanah dan pertumbuhan tanaman jagung pada lahan kering masam telah dilakukan di Kebun Percobaan Balai Besar Mektan di Serpong Tanggerang. Penelitian bertujuan untuk menguji efektivitas formula pembenah tanah organomineral untuk perbaikan sifat kimia tanah mineral masam dan meningkatkan pertumbuhan tanaman. Penelitian menggunakan rancangan acak kelompok dengan 8 perlakuan dan 3 ulangan. Perlakuan terdiri dari kontrol tanpa pupuk dan amelioran, NPK standar, 5 tingkat dosis pembenah tanah organomineral (OM) dan dolomit. Hasil penelitian menunjukkan bahwa pembenah tanah OM dapat meningkatkan pH tanah masam dan menurunkan kelarutan unsur beracun Al. Perlakuan dolomit 1,5 t/ha menunjukkan pengaruh paling besar dalam perbaikan sifat tanah, namun pembenah tanah OM 2 t/ha menunjukkan hasil yang hampir sama. Perbaikan sifat kimia tanah diikuti dengan pertumbuhan tanaman yang lebih baik jika dibandingkan dengan perlakuan NPK rekomendasi. Perlakuan pembenah tanah OM meningkatkan pertumbuhan tanaman dan diikuti peningkatan produksi jagung pipilan. Peningkatan produksi jagung sebesar 15,7% diperoleh dengan perlakuan pembenah tanah OM sebanyak 2 t/ha. Pertumbuhan dan produksi maksimum tanaman jagung dapat diperoleh dengan aplikasi pembenah tanah organomineral dengan dosis 1.750 kg/ha. Abstract Research of the effect of organomineral soil amendment formula to the soil chemical properties and the growth of maize on acid upland was carried out at the Experimental station of the Center for Agricultural Mechanization Research and Development in Serpong Tanggerang. The objectives of the study is to examine the effectiveness of organomineral soil amendment formula to improve the soil chemical properties of acid upland and improve plant growth. The study used a randomized block design with 8 treatments and 3 replications. The treatment consisted of controls without fertilizers and ameliorants, standard NPK, 5 dose levels of organomineral (OM) soil amendment and dolomite. The results showed that OM soil amendment can significantly increase soil pH and reduce the exchangeable aluminium, a toxic element to plant growth. Dolomite treatment of 1.5 t/ha showed the best effect in improving soil properties, but OM soil amendment 2.0 t/ha showed almost the same results. Improvements in soil chemical properties were followed by better plant growth compared to NPK treatment as a benchmark. OM soil amendment treatment gradually increased plant growth and followed by increased shelled grain corn. The increase of shelled grain corn yeild by 15.7% was obtained by applying OM soil amendment as much as 2 t/ha. Base on the yield curve, the maximum growth and yield of corn can be obtained by applying organomineral soil amendment at a dose of 1,750 kg/ha.
