    Performance of organically cultivated papaya under different irrigation levels and mulching methods
    (CCSHAU Hisar, 2022-09) Baljeet Singh; Mukesh Kumar
    An experiment was conducted at research field of Deendayal Upadhyay Centre of Excellence for Organic Farming, CCS HAU, Hisar during the year 2021-22 to study the effect of different irrigation levels and mulching methods on performance of organically cultivated papaya. The experiment comprised of twenty one treatments under the drip irrigation method with combination of three different irrigation levels viz. 50%, 75% and 100% of crop water requirement and seven mulching methods. The results showed that the plant height (240.73 cm), stem girth (46.03 cm), crown diameter (245.40 cm), number of flowers (65.67), number of fruits (42.67), yield per plant (54.30 kg) and total yield (135.75 t ha-1) were observed maximum for meeting 100% of crop water requirement with the application of 10 cm thick straw mulch in two-meter diameter around the plant and minimum for meeting 50% of crop water requirement without mulch condition. The soil moisture (20.18%) was found maximum for meeting 100% of crop water requirement with the application of plastic mulch in twometer diameter around the plant and minimum for meeting 50 % of crop water requirement without mulch condition. From the results, it is also observed that the irrigation water use efficiency (59.53 kg m-3) was found maximum for meeting 50 % of crop water requirement with 10 cm thick straw mulch in two-meter diameter around the plant and minimum (42.64 kg m-3) for meeting (42.64 kg m-3) 100% of crop water requirement without mulch under drip irrigation system.
