Experiment Title Influence of Tillage and drainage practices on growth and yield of papaya in heavy rainfall zone of south Gujarat
Research Type Departmental Research
Experiment Background Papaya (Carica papaya) fruit having commercial importance because of its high nutritive and medicinal value. Total annual world production is estimated at 6 million tons of fruits. India leads the world in papaya production with an annual output of about 3 million tonnes. Due to it high demand farmers have interest to grow papaya as their orchard crop. Papaya needs regular water for its rapid fruit development and yield. But this crop is susceptible to water logging. Water logging can cause the death of papayas in 48 hours. To remain healthy, the papaya plant needs regular rainfall or irrigation with good drainage while flooding for 48 hours is fatal. A balance between soil water and soil air O2 is important for root growth of papaya. So, this is a very serious issue for us to take immediate steps in the area of rainfed agriculture. Rainfed agriculture usually suffers from temporary waterlogging associated with excessive rainfall, flat topography or poor land and water management. Good drainage should be a periodical solution for these areas having heavy rainfall. Therefore, the farmers of south Gujarat (heavy rainfall zone) are facing hues loss in papaya cultivation due to stagnation of rain water in the fields. To elaborate these problems this experiment is formulated with the following objectives.
