Documentation and Empirical Assessment of Indigenous Technical Knowledge (ITK) for Pulse Storage in Tamil Nadu, India

The significance of pulses in nutritional security, crop diversity, and sustainability within crop production systems is widely acknowledged. Estimates suggest that post-harvest losses in pulses range between 25% and 30%. Proper storage techniques can aid in preventing these losses and increase the availability. Being rich source of protein, pulses are easily attracted by storage insects. Damage ranging from 30–70% of the grain has been reported in various publications. The current study aims to record Indigenous Technical Knowledge (ITK) concerning the methods used in pulse storage within rural regions of Karur, Dharmapuri, Krishnagiri, and Salem Districts in Tamil Nadu. Data was gathered from 120 farmers using a structured questionnaire. Among the various ITK methods implemented in the study area, a significant number of farmers (96 percent) widely adopted the practice of mixing red gram seeds with red earth slurry, drying them, and storing to prevent storage pests upto one year. This was followed by the practice of dusting ash with pulse seeds to manage storage pests at 93.00 percent. The study finds that traditional indigenous knowledge and practices are beneficial for sustenance, and these custodians of such knowledge play a vital role in agricultural advancement. To prevent the loss of such valuable knowledge, it is wise to protect and promote indigenous wisdom and understanding broadly for self-sufficiency with a principle aimed at reducing scarcity and hunger among local communities.
