Papaya

Water Management

The moisture required to grow papaya differs in each location depending on the ecology of the area.
Environmental and geographical factors like rainfall, temperature, light, wind, soil type and elevation play an important role in determining the amount of moisture needed to keep the papaya trees in good productive condition.
The age of the plant is also important in determining moisture requirements.
Young papaya seedlings need more moisture than older trees, which can maintain growth with little moisture because of their slower rate of vegetative growth.
Irrigate the young papaya seedlings about once or twice a week in irrigated orchards whereas for older trees bearing fruits, irrigate every 15 days or so.
Although bearing papaya trees do not need water as critically as small seedlings it is important that the tree has ample water in all times.
Prolonged moisture stress will slow down the growth and encourage the production of number of male or sterile flowers.
This will result into poor fruitset on the tree.
The papaya is adapted to a wide range of rainfall conditions ranging from 35 cm to 250 cm annual precipitation.
Excessive moisture affects the crop as well as fruit quality adversely.
Fruits of papaya produced in high rainfall and humid regions of the world are larger than those grown in the low rainfall regions irrespective of the varieties.
Papaya, in general, requires heavy irrigations both for establishment of young plants as well as for proper growth and fruiting, but it cannot withstand water logging and would develop 'wet feet'.
In the hilly regions of east and west coast of South India, papaya is found growing under rainfed conditions due to well distributed rainfall from South West and North East monsoons.
Fruitfulness in papaya depends on maintaining proper soil moisture.
Lower moisture levels shifted plants towards sterility and male floral characters, while higher moisture resulted in excessive production of undesirable carpelloid types.
Prolonged water stress resulted in stunted growth and poor fruitset.
Irrigate papaya trees at 10-12 days interval in winter and weekly once in summer if there is no rain.
Maintain adequate soil moisture in soil during summer in order to avoid flower and fruit drop.

Irrigation schedule

Stage of crops	Duration	No. of irrigation	Water level
Nursery	45 to 55 days	Daily with rose can Once in a week (Summer Season) Once in 10 or 15 days (Rainy Season)	25 to 30 litres per day if it is through drip
Main field	1 ½ month - 12th month		25 to 30 litres per day if it is through drip

Services Overview

The key services offered by Ikisan are:

System study, design and development of IT enabled solutions and services for the agri sector.

Execution of rural IT enabled projects on BOT/BOOT/Turnkey basis.

Development, Customization and Deployment of Ikisan's IPR protected software applications.

Providing support services and best management practices for augmenting the marketing development efforts of the groups agricultural input companies (NFCL and NACL).

Development and Dissemination of best practice and information though a unique multi lingual knowledge website for the agri sector.

Some of the key customers/partners that benefit significantly from our work include are Electronics Corporation of India Ltd, State Agricultural Marketing Boards, Central Research Institute for Dryland Agriculture, Tamilnadu, Centre for Development of Advanced Computing, Motorola Mobility (GOOGLE) etc.

As highlighted earlier Ikisan provides significant support to the market development and marketing efforts of NFCL and NACL by providing best practices and information across the agricultural input value chain - weather, soil, seeds, fertilizers, water, pesticides, output prices etc. that have enabled the companies to develop deep customer relationships and in turn enable them to grow above market growth rates. Recently example in fertilizers includes the development of Customized Fertilizer Grades (for NFCL across India that are crop and location specific have not only reduced the current consumption of fertilizers of farmers but have significantly enhanced crop yields and farmer incomes) that are expected to add significant revenues to the company.

Currently, agriculture value chain is driven by technical expertise. However, there is a lack of adequate Management knowledge and skills amongst the professionals. Therefore, Ikisan and XLRI, Jamshedpur have jointly developed an Agri Business Management Program for Agri-professionals and students. Ikisan provides the domain expertise while XLRI provides pedagogy. This program is a combination of virtual learning and campus based module at XLRI, Jamshedpur. This program has been highly appreciated.

Intellectual Property Rights for many software applications such as Field Manager, Vyapar, Mandi, Quick Solutions Systems, Management Time Table, Agri Information System and Agrecommerz belong to Ikisan. A significant recent development in this area is the introduction of Weather Based Crop Insurance. This entails setting up of Automatic Weather Stations, which provide dynamic village-level data essential for settlement of weather based insurance claims.
