An Optimization Study of Absorption Rate of NPK Fertilization under Multi-Depth of Black Loamy Sandy Soil

Sustainability is an empirical practice that focuses on social, economic, and environmental situations even for Cotton farming like systems to cater its agro-ecological problems. A suitable fertilization approach is worth implementing in cotton crop farming to get better absorbability of nutrients. However, when fertilization depth is altered to different depths its effect on absorption rate on cotton crop is unclear. An experimentation was performed on cotton crop using Black-Loamy Sandy soil of Vidarbha region of India by applying Carbamide (H2NCONH2) and Diammonium-Phosphate (NH4H2PO4) fertilization under multiple depth to determine the effect of NPK absorption rate. Three fertilizer placement depths comprising of 2 inches (FD2), 4 inches (FD4) and 6 inches (FD6) were tested. This experiment utilizes advanced IOT based sensors for measuring parameters and Lab-View framework to monitor the readings. This paper examines the effect of these parameters using Grey-based Taguchi analysis process. The scrutiny focuses on multi-response optimization of the NPK absorption rate using mini-tab software. Compared to various combinations, the optimum combination for low value of N, P & K was found as FDP = 6 inches, FQ = 40 gm-kg, SM = 70% (FDP-3-FQ-3-SM-3) gives the optimum NPK absorption rate. The projected, grey-based Taguchi method showed effective in resolving multi-response problem and such conclusions provide a practical recommendation for boosting the fertilizing policy in this region.
