Question: Write a note on Tactical Crop Management ?

Answer:

                 Tactical Crop Management

• The tactical management decisions necessary to maximize economic grain yield in  regions with predominant Mediterranean-type winter rainfall.
• Tactical decisions are defined as those relating to the period  immediately prior to planting through to harvest. Tactical management is the primary means by which growers respond to changing short-term environmental and economic conditions throughout the season.
• The review considers the published evidence supporting these decisions and covers cereal crops (wheat, barley and oats), legumes (peas, broad beans,chickpeas and narrow-leaved lupins) and oilseed rape.
• Criteria for in-season management decisions include soil and tissue testing for nutrients, knowledge of weed numbers and resistance status in the current and previous season, climatic conditions conducive to disease development, and knowledge of thresholds and biology of harmful insects. can justify the control measures.
• All of these decisions can be related to the timing of the first rains and the length of the growing season; the grain, grass, or weeds present during the preceding two seasons; the presence of crop residues that transmit pests and diseases; and the type of tillage used. Most of these indicators require further refinement through research on environments, soil types, crop types and production systems.
• Likely interactions between short-term or tactical management decisions, long-term or strategic decisions, and genetic factors are discussed. The widespread use of chemical products in the management of biotic factors that can affect crops stands out, as does the advancement towards various 'integrated' management systems for these threats to crop production.
• Most tactical decisions in rainfed farming systems appear to be supported by adequate evidence, although some decisions are still based on  practical experience and observation.
• The application of tactical management practices along with strategic management and the use of improved genotypes offers the opportunity to achieve a potential rainfall-limited  grain yield at a regional scale.
• When potential grain yields are not met in commercial crops, it is unclear whether this is due to insufficient adoption of existing  information or insufficient research to identify and address  underlying causes.
• We emphasize the need to develop a simple decision support tool to help farmers and their advisors respond to the variable seasonal conditions observed since the turn of the century.
