Losses caused

Affect growth and development of papaya leading to reduced fruit yield.
The extent of crop loss due to weeds is dependent on (a) the intensity of weed competition, (b) weed species predominant, (c) duration of weed competition, and (d) climatic factor such as rainfall, temperature and sunlight which affect weed growth.
Therefore, keep the weeds in papaya orchards completely under control. Control the weeds in papaya by mechanical (i.e. manual) or chemical methods.
For effective weed control, adopt a combination of both methods.
Mulching very effectively suppresses weed growth while conserving soil moisture.
Mulch the field wherever, possible, particularly in young plantings using grasses like Guatemala, Napier and other plant materials.
Among the various pre and post-emergence herbicides only paraquat and glyphosate have been reported to be used in papaya orchards.
Use paraquat @ 30 ml in 10 litres of water against broad leaved weeds in papaya plantations.
Use glyphosate @ 25 to 30 ml in 10 litres of water against grass and broad leaved weeds in papaya.
Care must be taken to avoid spray solution drifting on the young seedlings.

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.
