This study investigates the response of two varieties of plants, Sahoo and SVTD8323, to different fertilizer treatments. The Sahoo variety showed a quick response to the fertilizer treatments, with F1 and F2 treatments resulting in a 17% and 26% increase in plant height at 40 DAT, respectively. Both varieties showed an increase in the number of branches, with F2 treatment resulting in a 24% and 26% increase in Sahoo and SVTD8323, respectively. Both the varieties showed an increase in fruit weight, with Sahoo showing a 5.8% and 7.9% increase in fruit weight over the control at F1 and F2 treatment, respectively, while SVTD8323 showed a 2.9% and 5.5% increase in fruit weight over the control at F1 and F2 treatment, respectively. Both varieties followed a parabolic curve in yield per harvest across treatments, with Sahoo showing a 12.5% increase in yield at F1 treatment and a 13.5% increase at F2 treatment over the control treatment. Similarly, SVTD8323 showed a 12.5% increase in yield at F2 treatment over the control treatment. In a nutshell both the varieties consumed 29 to 39% lesser water and 25% lesser fertilizer than respective control treatment. The benefit to cost ratio was highest at F2 treatment in both varieties, with a ratio of 2.14 in Sahoo and 2.27 in SVTD8323, indicating that the IoT enabled precision farming profitable.

Bananas is the largest global production of all fruit crops and continue to play a key role in the economies of many developing countries. Banana cultivation is resource-intensive, consuming a lot of water and fertilizer. IoT-enabled precision farming has the potential to improve Grand Nain productivity by reducing input usage while still maintaining its economic viability as a cash crop. In this regard, there is a need to develop a banana cultivation package of practice that leverages the efficiencies gained by adopting IoT and sensor technologies to automate irrigation. This study aims to determine the most suitable irrigation and NPK fertigation strategy to minimize input use while maximizing profitability. This study includes three variable irrigation treatments based on soil water potential thresholds (-50, -100, -150 kPa) and three fertigation treatments (50%, 75%, 100% RDF) along with a control strategy that is based on the ICAR-NRCB recommended irrigation and 100% RDF fertigation schedules. The strategy with the − 50 kPa irrigation treatment and the 50% RDF of NPK fertigation treatment (I3F3) consumed 73% less water and 50% less NPK fertilizer, resulting in 12% less yield compared to the control strategy. However, the benefit-to-cost ratio of the I3F3 strategy was 1.61 versus the control strategy at 1.49. In the current agricultural paradigm, where soil degradation, water scarcity, and volatile market prices are impacting farmers' livelihoods, the I3F3 strategy ensures a more consistently profitable approach while significantly reducing water and NPK fertilizer usage, resulting in lower economic risks to farmers.
