Abstract: A field experiment was conducted at Plasticulture Farm, CTAE, MPUAT Udaipur in year 2019, to investigate the effect of chemical fertilizer scheduling on growth and yield performance of okra (Abelmoschus esculentus L.) under Sensor Based Automated Drip and Conventional Drip System. In this study four fertigation scheduling treatments of chemical fertilizer were taken. Recommended dose of chemical fertilizer N:P2O5:K2O, 60:30:30 kg/ha were supplied through different chemical fertilizers like Urea, Urea Ammonium Phosphate (UAP) and Sulphate of potash (SOP) during the crop period In this study the 40% and 60% of total recommended doses of fertilizer were applied during initial plus development stage and mid stage of crop growth respectively. The result revealed that the higher plant height and number of branch per plant in fertigation treatments T2 may be attributed to continuous supply and consequent availability of plant nutrients in the root zone during development and mid stage of crop growth. This is in conformity with the findings of Venkadeswaran et al., (2014). The highest pod yield of okra found under treatment T2 with a value of 11 t/hac, in which fertigation of NPK at recommended dose (60:30:30 kg NPK/ha) in equal splits through water soluble chemical fertilizers at 4 day interval under sensor based automated drip system. It may found because of that, under T2 treatment (fertigation in equal splits through water soluble chemical fertilizers at 4 day interval) nutrient supplied through continuous fertigation till late stage of crop growth. Fertilizer use efficiency was also found higher in sensor based drip irrigation treatments, it was probably due to less leaching of irrigation water with chemical fertizer because of frequent irrigation as per plant need. In this study phosphorus and potassium were supplied to okra crop through chemical fertilizers UAP and SOP respectively, because of that there was no precipitate of fertilizers was observed during mixing.
