Abstract: Pomegranate (Punica granatum L.) is a newly introduced as alternate commercial fruit crop against Nagpur mandarin in Satpura plateau region of M.P. In this situation, there are three flowering seasons, viz., January-February (Ambia bahar) June-July (Mrig bahar) and September-October (Hasta bahar). The choice of flowering/fruiting is regulated taking into consideration the availability of irrigation water, market demand and pests/disease incidence in a given locality. The crop of only one flowering season is taken in a year. Defoliation in pomegranate is an important practice followed to induce synchronized flowering. In the present study, an attempt has been made to test different concentrations of ethephon for their efficacy towards defoliation. The experiment was conducted during Ambia crop (Jan-Feb) 2018 using different levels of ethephon in the orchard of pomegranate at JNKVV, Krishi Vigyan Kendra, Chhindwara (M.P.) India. Six year old pomegranate var. Bhagwa plants of uniform size and growth were selected for the investigation. There were five treatments replicated thrice with two plant unit in RBD. Ethephon at different concentrations (600, 800, 1000 and 1200 ppm) were sprayed on pomegranate plants during stress period. All the treatments caused defoliation significantly over the control (untreated). Application of ethephon resulted in defoliation to a tune of 81.63% to 96.53% after 7 days of spraying. It was observed that spraying of ethephon at 1200 ppm was found to be effective for quick defoliation followed by 1000 ppm and 800 ppm, respectively. Therefore, it is advised to farmers that ethephon either at 1200 ppm or 1000 ppm can be successfully used for quick defoliation in pomegranate.
