What is maturity in agriculture?
Maturity is the process for the determination of the perfect moment or stage to pick up the crop. The moment or the stage at which the harvest of the crops is done is an important factor for good quality. Perfect quality can be attained when the harvest is done at a perfect stage of maturity.
What is maturity and how will you differentiate between physiological and commercial maturity?
Maturity is the harvest index most widely used in fruits. However, physiological maturity needs to be distinguished from commercial maturity. The former is reached when development is over. It may or may not be followed by the ripening process to achieve the commercial maturity required by the market.How does maturity at harvest affect the safety and quality of horticultural crops?
Maturity at harvest is the most important determinant of storage-life and final fruit quality. Immature fruit are highly susceptible to shriveling and mechanical damage, and are of inferior flavor quality when ripe. … With a few exceptions all fruits attain optimal eating quality when allowed to ripen on the plant.
What is meant by physiological maturity?Physiological maturity is defined as the occurrence of maximum seed dry weight and represents the end of dry weight accumulation and seed filling period. … The production of the yield occurs before physiological maturity, so plant and environmental factors that affect yield can do so only before physiological maturity.
Article first time published onWhat is the maturity indices of okra?
Maturity Indices Harvest typically occurs 3 to 7 days after flowering. Okra should be harvested when the fruit is bright green, the pod is fleshy and seeds are small. After that period, the pod becomes pithy and tough, and the green color and mucilage content decrease.
What are the different methods for estimating the maturity through maturity indices explain?
Assessing maturity • According to Reid (2002), the methods of determining harvest maturity are as follows • Physical methods: Size, shape, colour, texture etc. Chemical methods: Total Soluble Solids (TSS), acidity etc. Physiological methods: Respiration and ethylene production. 21.
What is maturity standard?
Maturity standards have been determined for many fruit, vegetable and floral crops. Harvesting crops at the proper maturity allows handlers to begin their work with the best possible quality produce. … Pickers can be trained in methods of identifying produce that is ready for harvest.
How does maturity affect the quality of fruits vegetables?
Maturity at harvest is the most important factor that determines postharvest-life and final quality (appearance, texture, flavor, nutritive value) of fruit-vegetables. … Overripe fruits are likely to become soft and/or mealy in texture soon after harvest.

What is the maturity indices of tomato?
Maturity indices for determining harvest time of tomato is a combination of fruit age, diameter and color, because these correlate significantly with physico-chemical and nutritional characteristics including total soluble solids (TSS), total titrable acidity (TTA) and protein content.
Which method of precooling is commonly followed by farmers?
Precooling can be accomplished by hydrocooling (immersion of the fruit in cold water) or vacuum cooling (moistening and then placing under vacuum in order to induce evaporative cooling).
What is maturity and types?
There is mental, physical, emotional, somatic growth and development in the child. Some of the changes are even genetic in mature. During one’s lifetime, there are many types of maturation. But the two most important kinds of maturity during childhood are physical and cognitive maturation.
What are the preharvest factors affecting quality?
The pre-harvest factors influencing postharvest quality are frequency of irrigation, use of fertilizers, pest control, growth regulators, climatic conditions like wet and windy weather, natural climates such as hailing, high wind velocity, heavy rainfall, and tree conditions (age, training pruning, light penetration, …
What are the maturity indices of mango?
Skin colour has been used as a standard maturity index for harvesting of mangoes [1, 6,15, 16, 23]. Maximum red coloration is more sensitive maturity index than the maximum yellow coloration [23] . Sometimes plant biologists determine the appearance of red color on the skin is not a reliable index of maturity.
