Abstract

Inappropriate cropping season and pattern resulted in the low production of seasonal food crops and the major cause of crop failure. A local wisdom called “Pranatamangsa” previously used to determine cropping time, now often miss due to climate anomaly. Crop growth is much affected by rainfall, solar radiation, and air temperature. The rainfall determines water availability and is essential requirement for crop growth. Planting time and cropping pattern until recently are adjusted to the climate variability and water availability to the crops. Therefore, the cropping calendar contained in this atlas is based on climate variability such as wet (El-Nino), normal, and dry (La-Nina) years. The atlas provides detailed description of planting time and crop rotation in each sub-district for each season in one year based on climate condition. The preparation of cropping calendar, both spatially and tabularly, provides information on cropping alternative for wet, normal or dry years. These alternatives were developed at 1:250 000 scale to be applied as reference in determining planting time and cropping pattern for each region and sub district. Hence, the risks of yield lost or crop failure can be avoided or minimized. Further, the policy and strategy of procurement and distribution of farm inputs particularly fertilizer and seed can be properly formulated. This cropping calendar was arranged through several steps: (1) climate data collection and farmer’s interview, (2) analysis of planting time and mapping, (3) field verification, and (4) refining the delineation of cropping pattern based on the sensitivity level. For a better planning of cropping time and pattern, this cropping calendar was arranged at the scale of 1:250.000 and attached with an information of cropping time and pattern at the sub-district level.

Abstract

Agricultural production is one of the most weather sensitive human activities that depend on daily atmospheric conditions. This review attempts to describe the meteorological data for crop requirements, some techniques of climate prediction and its use for crop simulations. Despite the rapid progress achieved in forecasting technology lately, further works are necessary for the real application. The amount and distribution of the rainfall in the coming season is necessary for planning crop cultivation particularly when climate anomaly arises. In agriculture the efforts to bridge the gap, climate forecasting results are the main input in crop simulation, especially for water and agro-climate management and cropping calendar.

Abstract

One of the most significant challenges for improving the agroclimate research is availability of integrated climate data. This paper reviewed several climate database systems development of national and international levels; such as those produced by Indonesian Meteorological Climatological  and Geophysical Agency (BMKG), World Meteorological Organization (WMO), and New Zealand climatic database systems. Indonesian Agency for Agricultural Research and Development (IAARD) through Indonesian Agroclimate and Hydrology Research Institute (IAHRI) has  developed a national climate database system (CDS), called as IAHRI CDS, as a basic part of agroclimatic researches. The system was integrated the numeric climate data and thematic spatial maps by applying Geographic Information System (GIS) and programming technologies. The data mainly comes from automated and manual climate stations of Ministry of Agriculture, BMKG and Irrigation service of each province. The development of IAHRI CDS is expected as a great resource for many potential applications on agriculture research in Indonesia. Keywords : Aagriculture, climate, database system, Indonesia
