Abstract

Central Java is one of provinces which producemedical crops such as singer (Zingiber officinale Rose). Recenly, the production technologies is expected to be more enviran-mental soundness. One of such technologies is sonic bloom. Basically,sonic bloom is the factor fertilization technology using main materialof sea weed containing trace mineral which is then combined with sound wave procucingsome ferequency to induce the opening of stomata. The sonic bloom test to ginger crops was carried out in Kembang Villages, Ampel Sub District, Boyolali Regency utilizing land of 1.1 ha wide. Result of the research revealed that in general sonic bloom application, had effects on productions and economic aspects. This technology was able to shorten donmancy periods and induce bud growth. Also, it was able to produce better rhizome vigor, more rhizome with longer adn bigger sizes. In term of yield, sonic bloom technology was able to increase ginger yield of Kapur and Gahaj varieties by 136% and 89%, respectively with better seed quality. In addition, the benefit of sonic bloom applied is better compared to control which gave MBCR values at 4.15 (kapur) and 5.08 (Gajah).

Abstract

At the recent, guide of Site Specific of Nutrient Management (SSNM) was developed by International Rice Research Institute (IRRI) in collaboration with Indonesia Agency for Agriculture Research and Development (IAARD) through online media based on internet website. To establish this recommendation technology, field evaluation of SSNM online application based on NM-Rice website was conducted. The assessment was conducted in Trayu and Dukuh Village of Banyudono Sub District of Boyolali District of Central Java Indonesia on dry season 2013 (May-September 2013). The assessment result showed that SSNM rice yield of about 63,2% of farmers in Trayu Village higher than FFP. Yield gap difference of SSNM online varied about 1-20% higher than FFP, whereas the others are almost similar until lower than FFP yield, by variation about 1-11%. The assessment of fertilizer recommendation in Dukuh Village showed that only about 33,3% of farmers cooperator have SSNM yield higher than FFP. Whereas, the others have SSNM online yield lower than FFP which its involved about 10% of farmers have similar yield between SSNM and FFP. An average of NPK rate of SSNM online in Trayu Village is lower than FFP. SSNM online rate for N fertilizer recommendation in this location are about 133 kg/ha  (93,9% lower than FFP), P2O5 about 38 kg/ha (73,8% lower than FFP), and K2O about 38 kg/ha (14,5% lower than FFP). Whereas in Dukuh Village, N rate of SSNM online recommendation are about 131 kg/ha (109,7% lower than FFP), P2O5 about 31 kg/ha (29,3% higher than FFP) and K2O about 30 kg/ha (63,3% higher than FFP). Generally, fertilizer recommendation based on SSNM online have benefit about 4,43% from existing.
