Abstract: Groundnut is an important oilseed crop cultivated over 20000 ha in Erode district if Tamil Nadu. 70 percent area comes under rainfed situations. The yield of groundnut was drastically reduced over the period of time in rainfed situation due to the compound problems such as leaf miner incidence and micronutrient deficiencies. ICAR - KVK, Erode made an attempt to manage pest and micronutrient deficiencies through Integrated Pest and Nutrient Management (IPNM) during 2018 – 19 and 2019 -20. The technologies comprised of seed treatment with Pseudomonas flourescens @ 10 gram / kg seed, pheromone trap @ 8 no / ha, need soap spray @ 0.25 kg /ha and groundnut rich @ 5 kg / ha. Adoption of IPNM practices reduces the pest incidence of 9.57 percent whereas in farmers practice it was recorded as 21.32 percent. The results showed that, number of filled pods was recorded as 33.51 numbers in IPNM practices and 24.40 filled pods recorded in farmers practices. The average yield of 21.35 qtl/ha pod yield was recorded in IPNM practices which was 13.06 percent yield advantage over farmers’ practices. The average highest net returns of Rs. 51858.50 / ha was recorded in IPNM adopted field with the benefit cost ratio of 1.87. The results indicated that, adoption of IPNM practices reduces the pest incidence and increases the groundnut productivity at field level.
