- Modern agriculture represents an evolving paradigm of agricultural advancements and farming methodologies aimed at enhancing efficiency while minimizing the utilization of natural resources such as water, land, and energy to meet global demands for food, fuel, and fiber.
- It is also known by various other terms such as agribusiness, intensive farming, organic farming, and sustainable agriculture.
- This approach to agriculture not only enhances food affordability, expands food availability, ensures food safety, and promotes sustainability but also contributes to increased oxygen levels near agricultural fields through heightened photosynthesis and facilitates the production of biofuels.
- However, it also brings about environmental challenges due to its reliance on high input–high output techniques involving hybrid seeds, abundant irrigation water, fertilizers, and pesticides.
PRECISION FARMING
- Precision farming, also referred to as precision agriculture, satellite farming, or site-specific crop management (SSCM), is a technology-driven farming management approach that revolves around the meticulous observation, measurement, and analysis of the specific requirements of individual fields and crops.
- In simpler terms, precision farming entails the collection and utilization of data pertaining to land areas for the purpose of monitoring and optimizing crop production.
PRECISION SIGNIFICANCE
Precision farming plays a pivotal role in modern agriculture by leveraging technology-driven solutions to manage a comprehensive range of Agricultural Management Systems (AMS). These interventions include:
- Continuous Data Generation: Precision farming involves the generation of on-site or on-farm data throughout various stages of agricultural practices, from sowing and crop growth to harvesting and post-harvest processing. By utilizing technological tools, this data is harnessed to enhance crop yield, quality, and profits for farmers within agricultural production systems.
- Data-Driven Decision Making: Robotics, analytics, remote sensing, Geographic Information Systems (GIS), and global positioning systems (GPS) are deployed in precision farming to make informed decisions about farm management. These technologies enable farmers to analyze data effectively and optimize their farming practices.
- Adoption of Advanced Technologies: Precision farming encourages the adoption of cutting-edge technologies by farmers to enhance agricultural productivity. These technologies include big data and advanced analytics capabilities, robotics, aerial imaging, and smart local weather forecasts. By integrating these tools into farming practices, farmers can improve efficiency and output.
- Climate Resilience: Precision farming strategies contribute to resilience against changing climatic conditions. By implementing data-driven approaches, farmers can mitigate unwarranted variances and stabilize crop yields. This adaptability enhances the sustainability and profitability of agricultural operations in the face of environmental challenges.
CHALLENGES FOR PRECISION FARMING
- Technology Adoption: Indian farmers face challenges in adopting new technologies due to high levels of illiteracy, both digital and numerical, as well as a significant digital divide. This hinders their ability to implement modern technology in their farming methods effectively.
- Landholding Size: The small size of landholdings in India poses a challenge for the adoption of precision farming. Limited land area restricts the economic gains from currently available precision farming technology, making it less financially viable for small and marginal farmers.
- Economic Hurdles: Precision farming requires expensive equipment and machinery, making the initial cost prohibitive for many farmers, especially smallholders. Additionally, the operational costs associated with maintaining and using precision farming tools present a barrier to adoption.
- Financial Accessibility: Access to loans and financial support for purchasing agricultural technology is crucial for encouraging the adoption of precision farming among Indian farmers. Lack of access to affordable credit can hinder investment in precision farming equipment and tools.
- Social and Behavioral Factors: Resistance to change and reliance on traditional farming methods are significant barriers to the adoption of precision agriculture in India. Farmers may be hesitant to adopt new technologies due to a lack of knowledge and focused instruction in precision farming practices. The prevalence of ancient farming techniques passed down through generations contributes to resistance and rigidity in adopting precision farming methods.
PROTECTED CULTIVATION OF HORTICULTURE CROPS
It is a method of cultivating crops in a controlled environment, allowing for regulation of factors such as temperature, humidity, and light according to the specific requirements of the crop. This controlled environment promotes healthier growth and increased production of crops.
Moreover, this approach holds immense potential for streamlining and optimizing the farm-to-plate supply chain by enabling food production closer to consumers. This can significantly contribute to enhancing the nation’s GDP and reducing dependency on imports.
Additionally, it opens up opportunities for cultivating horticultural crops in an entrepreneurial manner, particularly targeting urban and semi-urban markets.
In India, small and medium farmers are increasingly adopting this method for flower and vegetable cultivation, utilizing various types of modular protected structures based on their investment capacity and the availability of markets in their respective areas.
Objectives of Protected Cultivation:
- Protection from Abiotic and Biotic Stress:
- Shielding plants from adverse environmental conditions such as extreme temperatures, water fluctuations, and pest infestations to ensure their health and productivity.
- Efficient Water Use and Weed Control:
- Optimizing water usage while minimizing weed growth to conserve resources and enhance crop growth.
- Increased Productivity:
- Maximizing yield per unit area by providing optimal growing conditions and minimizing losses due to environmental factors.
- Reduction of Pesticide Usage:
- Minimizing reliance on chemical pesticides through the implementation of protective measures against pests and diseases.
- Promotion of High-Value Horticultural Produce:
- Cultivating high-value, high-quality horticultural products that meet market demands and fetch better prices.
- Improvement of Planting Material:
- Enhancing the quality of planting material by promoting healthy, uniform, and disease-free seedlings with better germination rates and adaptability.
- Year-Round and Off-Season Production:
- Facilitating continuous or off-season production of flowers, vegetables, or fruits to meet market demand and maintain supply consistency.
- Production of Disease-Free Transplants:
- Generating disease-free and genetically superior transplants for subsequent field planting, ensuring healthier crops and improved yields.
Limitations of Protected Cultivation:
- High Initial Infrastructure Cost:
- The significant upfront investment required for constructing protected structures and installing necessary equipment.
- Skilled Labor Shortage:
- Difficulty in finding skilled workers for managing protected cultivation systems and the challenges associated with their local replacement.
- Lack of Technical Knowledge:
- Limited understanding of the specialized techniques and practices involved in growing crops under protected structures among farmers and agricultural practitioners.
- Intensive Operations:
- The need for constant and intensive labor and management inputs to monitor and maintain optimal growing conditions within protected environments.
- Supervision and Monitoring:
- Continuous monitoring and close supervision required to address issues promptly and ensure the proper functioning of the protected cultivation system.
- Pest and Pathogen Management:
- Challenges in managing certain pests and soil-borne pathogens effectively within protected environments due to limited control options.
- Maintenance and Repair:
- The ongoing need for repair and maintenance of infrastructure and equipment, which can be time-consuming and costly.
- Market Dependence:
- The necessity for assured market access and demand to justify the significant investment of resources in protected cultivation systems.
