1.1 Traditional Method

Traditionalagriculturalpracticeshavebeenfollowedfor centuries and primarily rely on manual labor, natural resources,andfarmers’experience.Thesemethodsinvolve conventionaltoolsandtechniquesforactivitiessuchasland preparation,sowing,irrigation,andcropmonitoring.While traditional farming has sustained food production for generations, it faces several limitations in meeting the demandsofmodernagriculture.

Intraditionalsowingmethods,seedsareusuallyscattered manually or placed using basic hand tools. This approach oftenresultsinunevenseeddistribution,improperspacing, and inconsistent sowing depth, which negatively affect germinationratesandoverallcropyield.Seedwastageisalso acommonissueduetothelackofprecisioninmanualsowing processes.

Irrigationintraditionalagriculturetypicallydependson methodssuchasfloodirrigation,canalsystems,ormanual watering. These techniques do not consider real-time soil moisture requirements and frequently lead to excessive waterusage.Over-irrigationcancausesoilerosion,nutrient leaching,andwaterlogging,whileunder-irrigationmayresult incropstressandreducedproductivity.Moreover,traditional irrigationpracticesrequirecontinuoushumansupervision, increasinglabordependency.

Weather assessment in traditional farming is largely based on farmers’ experience, observation of natural indicators, or historical seasonal patterns. Although this knowledgeisvaluable,itlacksaccuracyandreliabilityinthe face of changing climate conditions. Sudden variations in temperature,rainfall,orhumiditycancauseunexpectedcrop losses, as farmers are unable to make timely decisions withoutscientificforecastingtools.

Additionally, traditional farming methods are laborintensive and time-consuming. With increasing labor shortages and rising operational costs, it has become challenging for farmers to maintain efficiency using conventional techniques alone. These limitations highlight theneedformodern,automatedsolutionsthatcanimprove precision, reduce resource wastage, and enhance productivity.

The challenges associated with traditional agricultural methods emphasize the importance of adopting smart

technologies such as robotic systems and sensor-based automation, which can overcome these inefficiencies and supportsustainablefarmingpractices.
