Maize productivity in Indonesia is relatively low (3.66 t/ha), yet in some provinces it rises above 4.0 t/ha. This higher productivity is due to farmers' adoption of production technology, including the use of improved maize varieties. This paper describes the progress of the Indonesian Agency for Agricultural Research and Development's breeding program to develop several improved maize varieties in Indonesia. The research compares the characteristics and yield potential of nine open pollinated maize varieties (OPVs) and 13 hybrid maize varieties that have been released by the government since 1992. Findings show that B11-209 and Nei 9008—female parents of hybrids Bima-2 and Bima-3—gave better combining ability with Mr14 than Mr4 and could replace Mr4 as testers in the hybrid breeding program. The Modified Reciprocal Recurrent Selection breeding method effectively improved grain yield of the MSJ2 population. The authors conclude that OPVs are still needed, especially in areas outside Java with high soil acidity, low soil fertility and drought stress. Furthermore, development of quality protein maize varieties is needed to improve the low nutrition value of children in some parts of Indonesia, especially in drought prone areas.

Weather index insurance for maize production in eastern Indonesia: a feasibility study

IFC(2011)WeatherIndexInsuranceMaizeProductionEasternIndo.pdf

This study explores the feasibility of weather index insurance (WII) in providing cost-effective risk management benefits to rural people for coping with catastrophic events. It uses a case study on drought coverage for maize production in three provinces in eastern Indonesia: East Java, West Nusa Tenggara and East Lombok. Prototype WII contracts were developed for selected areas within these provinces. The contracts were found to provide appropriate coverage for crop losses resulting from rainfall deficit, but the estimated premiums for farmers would be expensive. An initial estimation suggests that coupling WII with credit from formal financial institutions could reduce the cost of borrowing for farmers. However, the actual economic or commercial feasibility of WII products can only be made after substantial test marketing of these products demonstrates their attractiveness. The study concludes that WII may offer a promising approach to insuring maize production in Indonesia, but the instrument is likely to apply only to specific crops in specific areas. WII should not be considered a universal solution for lowering the risk of agricultural production across the whole country.

Effect of date of planting and rainfall distribution in the yield of five cassava varieties in Lampung, Indonesia. In 'Cassava's potential in Asia in the 21st century: present situation and future research and development needs

Lampung is the primary cassava producing region in Indonesia, yet the province regularly experiences prolonged dry periods. This study examines drought tolerance for varietal selection prior to distribution, assessing the potential impact of drought (two or more months of <100mm rainfall) on root yield, starch yield and content in five selected varieties. Trial design comprised a 0.1ha plot of each variety (no replication) with sub-plots of staggered planting dates to impose dry periods at different growth stages. Results found no varietal difference in root yields in the absence of a dry period. However, root yields were reduced between 14.88t/ha and 20.11t/ha with exposure to a dry period. CMR30-56-1 was ranked the most drought tolerant and Adira 4 the least drought tolerant. Starch yields were reduced by 50 per cent when subject to a dry period and yield reductions increased with length of the dry period. Dry conditions between the third and eighth month after planting had the greatest impact on yield suggesting that rain during this period is critical for root bulking. Effects on starch content were also assessed as starch content is a price determinant for fresh cassava. Dry periods reduced starch content, but to a lesser extent, one to three months before harvest.
