Decision support system in precision farming is

Correct option is A

• The correct answer is (A) Nutrient Expert.

• Nutrient Expert is a decision support system used in precision farming and site-specific nutrient management.

• It provides field-specific fertilizer recommendations based on factors such as crop, soil conditions, previous crop, nutrient management practices and expected yield.

• The system helps farmers make balanced and efficient fertilizer-management decisions according to the nutrient requirements of a particular field.

• Nutrient Expert supports the principles of site-specific nutrient management (SSNM) by providing recommendations suited to field conditions rather than applying the same fertilizer dose uniformly.

• It helps improve nutrient-use efficiency, crop productivity and economic returns while reducing unnecessary fertilizer application.

Information Booster:

• Nutrient Expert: Decision support tool for field-specific nutrient management.

• Precision farming: Uses spatial and temporal variability within fields to improve management of crops and agricultural inputs.

• Site-specific nutrient management: Adjusts fertilizer application according to the specific nutrient requirements and conditions of a field.

• Weed Seeker: Uses sensor technology to detect weeds and facilitate targeted herbicide application.

• Phytotron: A controlled-environment facility used for studying plant growth under regulated temperature, light, humidity and other environmental conditions.

Why Other Options are Incorrect:

(A) Nutrient Expert

• Correct. Nutrient Expert functions as a decision support system for providing site-specific fertilizer and nutrient-management recommendations.

(B) Weed Seeker

• Incorrect. Weed Seeker is a weed-detection and precision herbicide-application technology that uses sensors to distinguish weeds from crop plants.

• It is not primarily a nutrient-management decision support system.

(C) Phytotron

• Incorrect. A phytotron is a controlled-environment growth facility used for experimental studies of plant responses to environmental factors.

• It is not a decision support system used for routine precision farm management.

(D) Kisan Suvidha

• Incorrect. Kisan Suvidha is a farmer-oriented agricultural information service/application providing information and services related to agriculture.

• It is not specifically the nutrient-management decision support system identified in the question.

(E) Soil Health Card

• Incorrect. A Soil Health Card provides information about soil nutrient status and fertilizer recommendations based on soil testing.

• It is an important soil-management tool but is not the specific decision support system represented by Nutrient Expert.
