Winter Rice Trend Analysis and Change Point Detection in Assam's North Bank Plains Zone (NBPZ): A Non-Parametric Approach

Rice from Assam is well-known for having a wide range of genetic varieties. In the past, Assam produced more rice due to its geographic location and climatic conditions. The main rice crop in Assam is winter rice, which makes up a significant amount of the state's overall rice production. The NBPZ is one of the key locations where agriculture provides many people with a means of subsistence. The goal of the study is to determine the turning point for winter rice productivity in Assam's NBPZ by analyzing trends regarding winter rice output, area, and productivity. The transition point for the productivity of winter rice was discovered by analyzing more than 30 years of NBPZ data. The study also shows the NBPZ to not just be restricted to researching winter rice's climate-resilient productivity but to also have a critical need to adopt efficient crop production and productivity measures. Thus, the study's findings are anticipated to be able to help policymakers create an effective agricultural policy that is easier for farmers to adopt.
