Data-driven approach for analysing the impact of external factors on pearl millet and stover yield

The objective of the study is to explore the relationship between external factors such as linkage with self-help groups (SHGs), crop diseases, ground water quality, soil testing, rainfall, and temperature during cultivation impact with pearl millet yield and stover yield. The responses from 473 farmers are collected through structured survey questionnaire. The outcomes reveal that the relationship of all external factors is statistically significant for both yields except the temperature during cultivation. The analysis of variance (ANOVA) and Pearson coefficient of correlation indicates a statistically significant positive correlation between pearl millet yield and stover yield. The current study is first of its kind related to impact of external factors on pearl millet yield and stover yield. The outcomes of the study will help policymakers in developing strategies for enhancing pearl millet and stover yield, which in turn will increase farmer income. In addition to having access to an incentive scheme for free testing of their ground water quality and soil health, the farmers have to be linked to self-help groups (SHGs).
