Crop Calendar in agriculture defined as a written document that explain the farming activities that the farmers wish to carried out according to crop manual and follow package technology at the correct timing. Crop Calendar as a tool in farming activity and as a main references for farmers in managing their farm from the early stage of land preparation to the harvesting stage and next planting cycle. This article I would like to share knowledge about crop calendar in food production farming activity based on my lecture for ASEAN-JAPAN Technical cooperation training program.


There was two types of crop calendar in agriculture technology extension system. There were ANNUAL CROP CALENDAR and INDIVIDUAL/SINGLE CROP CALENDAR. The Annual Crop Calendar showing the whole year crop pattern calendar for the nation or an large area from early January to December. This calendar will determine what type of suitable crop to grow following the climate or season such as weather ,
temperature, rainfall, dry period and other related factors. The crop pattern has to be followed by all farmers so that it will produce the best production level. For example the annual China (See diagram next) shoeing what type of crop in January (Winter wheat and Sunflower), May (Rice, Maize, Soybean, Cotton & many others) and in December (Sunflower & Winter wheat). The farmers in China has to follow the annual crop calendar released by Ministry of Agriculture China.

Single Crop Calendar is a calendar showing the activity of the individual crop from land preparation activity to the harvesting and replanting for the next season. The calendar able to show detail package technology by days or weeks following crop package technology. The calendar (as below - Refer diagram 2) for mustard (Brassica spp - sawi) shown in a diagram with detail explanation. This calendar has 8 activity box from sowing to harvesting in 28 days period. The crop calendar also shown in Table Form to show for more detail information (Refer Diagram 3).


Components of crop calendar includes type of crop selected, Time Frame Bar, activity before planting, activity after planting, agronomic practices, harvesting and marketing activity. Determine what type of crop with a reference planting period and to package technology. Activity before planting indicated as land preparation activity until sowing or planting activity. Th bar colored and marked as MINORS (-) to indicate how long land preparation period. If indicated as "-7" means that it was 7 day before planting for land preparation activity such as ploughing, rotor, raising bed, removal of grass, plastic silver shine layering, basal fertilizer application and irrigation system installation.
