Cashew cultivation plays a crucial role in the
agricultural economy of coastal India, providing
livelihoods
for
numerous
farmers.
However,
suboptimal nutrient management practices often
hinder cashew productivity in the region. Inefficient
fertilizer application, inadequate understanding of soil
nutrient requirements, and lack of site-specific
recommendations contribute to yield losses and
increased input costs. To address these challenges, the
present study proposes the utilization of a mobile app
as a tool for enhancing site-specific nutrient
management in cashew cultivation. The mobile app
aims to provide farmers with real-time information,
tailored nutrient recommendations, and application
schedules based on their specific field conditions. By
optimizing nutrient management practices through
this technology-driven approach, cashew farmers can
potentially improve their productivity, reduce
environmental impact, and enhance their profitability.
METHOD
Mobile App Development:
The first step involved developing a mobile app
specifically designed for cashew farmers in coastal
India. The app was designed to provide a user-friendly
interface, allowing farmers to input their field data,
access soil nutrient information, and receive
customized nutrient recommendations.
Database Creation:
A comprehensive database was compiled, consisting
of soil fertility data from cashew-growing regions in
coastal India. This database included information on
nutrient levels, soil types, and cashew productivity
from various locations. The data formed the basis for
generating site-specific nutrient recommendations.
Nutrient Recommendation Algorithm:
An algorithm was developed using the database to
generate nutrient recommendations based on the
farmer's input data, such as soil type, nutrient levels,
and cashew growth stage. The algorithm considered
optimal nutrient ratios, crop nutrient requirements,
and soil fertility indicators.
Field Trials:
Field trials were conducted in collaboration with
cashew farmers in coastal India. Participating farmers
were provided access to the mobile app and trained on
its usage. Experimental plots were established, and the
app-guided nutrient management practices were
implemented. Control plots with conventional nutrient
management practices were also maintained for
comparison.
Data Collection and Analysis:
Data on nutrient application, crop growth, and yield
parameters were collected from both the app-guided
plots and control plots. Parameters such as plant
height, leaf nutrient content, flower and fruit
development, and yield were recorded at regular
intervals. The collected data were analyzed to assess
the impact of the mobile app on nutrient management
practices and cashew productivity.
Evaluation and Feedback:
Farmers'
feedback
regarding
the
usability,
effectiveness, and economic viability of the mobile app
was collected through surveys and interviews. Their
perspectives on the app's impact on nutrient
management and productivity were recorded to
evaluate its overall performance.
