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.

Produktivitas kedelai >2 t/ha pada agroekologi tersebut dapat dicapai dengan teknik budidaya yang baik. Tujuan penelitian adalah adalah untuk mengevaluasi efektivitas, kelayakan teknis dan finansial teknologi budidaya kedelai pada lahan pasang surut (KEPAS). Penelitian dilaksanakan pada lahan pasang surut tipe C di Jambi seluas 40 ha dan Kalimantan Selatan seluas 11 ha pada tahun 2018. Komponen teknologi KEPAS yang utama adalah penggunaan varietas Anjasmoro, saluran drainase setiap 2,5-3 m, ameliorasi lahan dengan 750 kg/ha dolomit dan 1 t/ha pupuk organik, serta pemupukan 150 kg/ha Phonska dan 100 kg/ha SP36. Hasil penelitian menunjukkan bahwa teknologi KEPAS efektif untuk budidaya kedelai pada lahan pasang surut dengan tingkat hasil 1,8-2,8 t/ha di Jambi dan 1,4-3,2 t/ha di Kalimantan Selatan. Teknologi KEPAS secara teknis layak, dan juga menguntungkan yang diindikasikan oleh nilai R/C ratio>1 pada hampir semua petani kooperator. Meskipun demikian, tingkat kelayakan finansial beragam dari tidak layak hingga layak yang diindikasikan oleh nilai B/C ratio 0,58-1,49 di Jambi dan 0,04-1,47 di Kalimantan Selatan. Teknologi KEPAS secara finansial layak pada tingkat produktivitas setidaknya 2,3 t/ha. Tingkat kelayakan finansial teknologi KEPAS berpeluang dapat ditingkatkan melalui mekanisasi pada kegiatan penanaman, serta panen dan prosesing.

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

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.
