Aims:The characterisation of the spatial variability of plants attributes associated with productivity is important for the refinement of agricultural management practices and the evaluation of the effects of agriculture on environmental quality. The objective of this research was to study the correlations of phenotypic variables, the productivity of papaya and spatial variability using a geostatistical technique. Place and Duration of Study: The research was carried out in a commercial crop of papaya (Carica papaya L.) located in the northern state of Espírito Santo, Brazil in a typical cohesive Yellow Ultisol, between June 2010 and June 2011. Methodology: The following variables were measured in each sampled plant: height of the plants (HPL); diameter of the stem at 0.20 m from the ground (SDI); lower insertion height of the first flowers (IHF); number of leaves totally open (NTL); number of flower buds (NFB); crown diameter (CRD); the height of the first fruit harvest (HFR); the total number of fruits harvested; the mass of the harvested fruit; the average number of fruits produced per plant (NFR); the average fruit mass produced per plant (kg plant -1

SUMMARYPapaya has never been found in the wild, but is believed to have originated in tropical America from where it has spread throughout the tropics and subtropics. This fruit crop is particularly important in India and Brazil. Most research on the water relations of papaya has been undertaken in Brazil and on the island of Guam (United States of America). Papaya is a short-lived large herb, growing to a height of up to 10 m. Leaves emerge from the upper part of the unbranched stem. After a juvenile period, lasting for about two months, flowers begin to develop in leaf axils. Flowering continues throughout the year as new leaves emerge. The plants, which are dioecious, begin to bear fruit within a year after planting, sustaining high yields for two years before yields decline. The ‘effective’ root depth varies with the method of irrigation, but can reach 0.55 m. The seedlings and the trees are susceptible to wind damage, a topic that has been well researched. Stomata are only found on the abaxial leaf surface. They are sensitive to changes in the saturation deficit of the air. Stomata also respond quickly to changing light conditions. On clear days, midday suppression of photosynthesis occurs as a result of partial closure of the stomata. In the morning, there is a time lag between water loss by transpiration and sap flow, as water is taken from storage in the hollow stem. Few attempts have been made to measure the actual water use of papaya, and there are no reliable published values for the crop coefficient. Limitations to the design of the papaya irrigation experiments reported so far make it difficult to reconcile the results in practical ways. Water productivities equivalent to 1.8 to 2.8 kg (fresh fruit) m−3 (irrigation water) have been obtained. Although papaya is generally considered to be drought sensitive and responsive to irrigation, there is a shortage of good experimental evidence to support this view. There is a need to establish practical irrigation schedules for this remarkable crop. A uniformity of approach to irrigation experimentation and a common, universally agreed nomenclature would facilitate this process.

The papaya (Carica papaya L.) is a tropical fruit that is widely cultivated and consumed, both for its agreeable flavor as well as its many pharmacological properties. This review will discuss the fruit's origin and principal growing regions in the world and will briefly explore its nutritional and pharmacological attributes. In addition, we will identify and comment on some of the most common physiological disorders that occur postharvest. Such disorders compromise the quality of the fruit, bringing financial losses to the productive sector, along with serious economic and social consequences to papaya-growing countries. Among these disorders, physiological bruising, also known as "skin freckles", characterized by the appearance of blemishes on the fruit while still in its growth stage, is one of the main problems associated with the crop. Possible causes of and current information on bruising are dealt with in this article. Other physiological disorders of the papaya such as pulp flesh translucency, pulp softening, and hard lumps in papaya flesh are also discussed.
