Evaluación de la uniformidad del riego y efecto del fertirriego nitrogenado en un huerto de lechosa (Carica papaya L.)

nitrogenous fertilization and watering performance on yield of a papaya orchard cv. red cartagena was studied. four treatments of nitrogenous fertilization and three of watering were evaluated using drip lines. the soil moisture was registered by tdr and gravimetry. the harvest began at the end of the rainy period and it prolonged for twenty one weeks in the dry period. it was found that the emitter discharge was highly uniform in its different operation modalities. the nitrogenous fertilization did not affect the plant yield but permitted earlier maturity of fruits. similarly, the watering treatments did not affect the yield which was attributed to the effect of the water stored in the soil profile during the rainy period.
