I am about to wrap up the research so i thought sharing my finding out of the whole research.

Interestingly, I have explored the flaws and major successful platforms that could actually contribute to increase or monitor the efficiency of the IoT in farming.

Findings for the efficiency of the system has,

Zigbee being most widely and most compatible technology network that is used with sensor typologies or infusion with other technologies to give out the best results. As seen from the analysis, it has proven to be the most secure technology with high encryption of the data that reduce the security cost of the system overall. And Wi-Fi with medium efficiency and low accuracy proved to be the less used and non-reliable technology used for precision farming. On the other hand Bluetooth being low cost technology with very low energy consumption could be used for very short distance communication of sensor nodes. And WiMAX being very expensive technology also limits its use as it cannot prove to be efficient is terms of cost.
