There are many factors that would influence a growers decision to change irrigation systems. Identify 1 other factor the grower would need to consider before deciding to swap and explain how this factor would influence the decision. Include examples of the types of information or calculations the grower may need in order to make this decision.

Irrigation is an important part of crop production. Irrigation increases crop yield by

Which one of the following is not an adverse effect of irrigation?Select an answerAIrrigation changes cropping patternBWater intensive crops are grown in dry areasCSalinisation of soilDIncreases crop yield

Which of the following does NOT describe the predicted result of replacing flood irrigation systems with drip irrigation systems? (1 mark)a) Improve efficiency of water useb) Reduce run-offc) Eliminates the need to use fertilizerd) Allows irrigation of specific crops or areas

The green revolution centered on the development of which of the following?Multiple Choiceprograms to reduce reliance on pesticideshigh-yield breeds of food cropsimprovements in irrigation practices leading to water conservationcrop rotation to improve nutrient levels in the soil

What is the primary factor determining the success of crops in rain-fed agriculture in India?Soil qualityPest controlTimely monsoons and sufficient rainfallFertilizer application       How do check-dams contribute to groundwater recharge and sustainable irrigation practices?By preventing soil erosion.By stopping rainwater flow and allowing it to percolate into the ground.By creating a habitat for aquatic animals.By promoting the growth of water-intensive crops.       What does crop rotation involve in agricultural practices?Planting the same crop in the same field continuously.Growing different crops on a piece of land in a pre-planned succession.Randomly changing crops every seasonReplanting the harvested crop immediately after harvest.       Why is proper planning essential in implementing inter-cropping techniques?To ensure a visually appealing arrangement of crops.To maximize crop yield and minimize competition for resources.To simplify irrigation processes.To minimize labor requirements during planting.       How does inter-cropping differ from mixed cropping?Inter-cropping involves planting the same crops together, while mixed cropping involves planting different crops.Inter-cropping involves planting different crops simultaneously in a definite pattern, while mixed cropping involves growing crops without any specific arrangement.Inter-cropping is only practiced in organic farming, while mixed cropping is common in conventional farming.Inter-cropping and mixed cropping are interchangeable terms for the same farming practice.       What is one of the preventive measures to control storage losses in grains?Increasing the storage temperature.Fumigation using chemicals to kill pests.Allowing direct sunlight exposure without drying.Storing grains without cleaning them.       Why is proper drying of produce essential before storage?To enhance the flavor of the grains.To reduce the weight of the produce.To kill pests and pathogens.To minimize moisture content and prevent deterioration.       Which elements are considered macronutrients in soil for plant growth?Iron and zincNitrogen and phosphorusManganese and boronCopper and molybdenum       Why are rain-fed farming areas more vulnerable to drought?They receive excessive rainfall.They heavily rely on irrigation.They do not use irrigation and depend solely on rain.They are located in regions with consistent rainfall.       What limitation has been introduced in livestock farming due to growing awareness of animal welfare?Increased use of antibioticsDecreased emphasis on breedingNeed for humane treatment of livestockReduction in feeding practices
