Mango (Mangifera indica) is a perennial fruit plant belonging to the family Anacardiaceae. Climatic resolutions for high productivity of mangoes are essential in SSoptimum ranges along with the sustainable pathway. Tropical and subtropical locations are ideal for growing mangoes with the optimum temperature range and the average annual rainfall. In Sri Lanka, flowering is highly affected by one of the major climatic issues of rainfall patterns and results in irritations of yield & quality of the crop. Thus, water-logging soils are not suitable for mango production.
Mango production and plant metabolism depend critically on the presence of a water shortage or water stress environment. Therefore accurate climatic data readings are crucial for the management of growth stages in mango plants. Important aspects of plant growth and development can be tracked through the use of precision agriculture. The SenzAgro Agricore platform is utilized to track the parameters in real-time, which includes relative humidity, temperature, electron conductivity (EC), and soil moisture. Many metabolic complications in mango cultivation are solved by sensor-based daily monitoring of soil moisture, air temperature, and relative humidity. Managing the amount of water is feasible via soil moisture analysis. Irrigation is used under strict management following this time of water scarcity. Thus, to investigate the accurate and sustainable climatic requirements with effects on the water stress conditions for high productivity in mangoes is strictly identified through this study.
The research was conducted on a Mangifera(Pvt)Ltd, located in the Anuradhapura district which is from the agro-ecological region of DL1 (Low country, Dry zone 1) and selected uniform growth, after completing the first cycle of fruit initiation and harvesting trees. The experiment time was about 3 months within the flowering and fruiting seasons. Two main plots named block 3 (For the treatments) and Block 2 (For the control) were studied for this research. Water stress was given accordingly and after one month of the water stress period, three irrigation applications (60 liters of water per selected tree) were used to block 3 according to the digital readings. Block 2 remained under the common agronomical practices. By using a digital platform and farm.
