Studies on seed germination and seedling growth of papaya (Carica papaya L.) CV. madhubindu as influenced by media, GA3 and cow urine under net house condition

Abstract

An experiment entitled “Effect of GA3 and cow urine with different media on seed germination and growth of papaya seedlings (Carica papaya L.) cv. Madhubindu under net house condition” was carried out at Horticultural Research Farm, Anand Agricultural University, Anand during June – July, 2016. The treatments comprised combination of soil, vermicompost and cocopeat with varying levels of GA3 and cow urine. Altogether, 18 treatments were applied in a factorial CRD with three repetitions. The seeds were sown in plug tray which is filled with respective media and treated with GA3 and cow urine. The results showed that the application of treatment G3M1 [GA3 @150 mg/l dipping for 12 hours and soil + cocopeat (1:1)] was found better for early germination as well as higher germination percentage and length of root. While, G6M1 [cow urine 10% dipping for 18 hours and soil + cocopeat (1:1)] had enhanced plant growth by increasing seedling height, stem diameter, fresh weight of shoot and leaf area.
