Technology Dissemenation Through Frontline Demonstration

1. Organic farming in major spices


     Addition of large quantities of fertilizers and heavy use of plant protection chemicals to boost the yields became common practice in all producing countries affecting the quality of products. In view of the damage done to environment and human health by conventional intensive farming practices, the demand for organic products have come up world over.  In view of importance of spices both as food adjunct and as medicine, the demand for organically produced spices is increasing substantially. DASD had initiated farmer participatory demonstration in a compact area to promote latest technologies in organic farming in spices during 2008-09 and is being implemented successfully by different agencies in the subsequent years.

      During the year 2015-16, it is proposed to establish 78 frontline demonstration plots at various University centres / ICAR Institutes/ Farmers fields for organic cultivation of various spice crops. The programmes will be implemented through SAUs, ICAR Institutes and reputed NGOs.  A total financial outlay of Rs.70.75 lakhs may be earmarked for this component.

2. Demonstration plots for seed spices

     Seed spice is one sector, where productivity is much below the desired level. This is mainly because of non adoption of high yielding/ disease tolerant/resistant varieties and modern technologies evolved for different crops. The Directorate proposes to establish 57 demonstration plots of size 1 ha each for seed spices with an assistance of Rs 0.40 lakh /unit during the year 2015-16. The total financial allocation  for this programme is Rs 22.80 lakhs.


3. Demonstration plots for aromatic plants

     The level of information on production technologies, improved varieties and commercial importance of aromatic plants is meager among the farming community.  To popularize technologies on aromatic plants the Directorate proposes to establish 17 demonstration plots of size 1 ha in aromatic plants with an assistance Rs 0.80 lakhs/unit. The total financial allocation for this programme for the year 2015-16 is Rs.13.60 lakhs.


4. On farm water management - setting up Micro irrigation (drip irrigation)

     The water use efficiency under conventional methods of irrigation practiced in India, is very low due to substantial conveyance and distribution losses. The estimated irrigation water use efficiency in India is of the order of about 35-40 percent. With deteriorating surface water infrastructure and rapid decline in ground water tables in large parts of the country, in the face of increasing demand for water from all sectors of the economy, there is a widespread concern for using the available water more efficiently. Micro irrigation system, comprising drip and sprinkler technologies, has emerged as an effective tool for water conservation and improving water use efficiency. Drip irrigation, is an irrigation method which enables saving of water by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the  root zone. In water deficit areas drip technique is recommended as ideal irrigation method.      

     Productivity and quality of any crop is affected by availability of optimum level of irrigation during critical stages of growth. The water holding capacity of soil has gone down due to decreased organic matter content as a result of intensive cultivation. Developing water resources, adoption of water conservation methods, use of appropriate irrigation method etc. can ensure water availability throughout the crop period and thus help in uniform growth and development of plants. Growth and yield parameters of spices like Black pepper, Chilli, etc showed significant increase in response to irrigation.

     Experiments show that pre-monsoon irrigation helps in early spiking and better crop yield in black pepper. Yield of Ginger and Turmeric has shown significant increase with micro irrigation. As major seed spices are grown in arid and semi arid zones, adoption of suitable irrigation methods will be beneficial in increasing the productivity of the crop. This programme aims at enhancing water use efficiency by promoting efficient on-farm water management technologies and equipments in spice crops.  It is proposed to set up 30.5 No. of demonstration plots on drip irrigation system in different spices in SAUs/ ICAR institutes and selected farmers fields as shown in the table below.

Size of the demonstration plots is 1 ha and assistance provided is based on the spacing of crops as approved in NMSA guidelines. An amount of Rs 12.2274 lakhs is earmarked for this purpose for the year 2015-16.


5. Demonstration of effective and eco-friendly management of white-grub using Entomopathogenic nematode (EPN) in Arecanut

     White grub is a key pest of Arecanut and its intercrops in sandy loam soils of Karnataka and Kerala. It damages the seedlings and adult palms by feeding on roots, boring the bole and collar region. Presently the grubs are managed with application of high dose of pesticide frequently which is deleterious to ecosystem. EPNs are identified to be effective and environmental friendly alternative to manage white grubs by CPCRI, Kasargod. To popularise ecofriendly management of whitegrub using EPNs,  the directorate  establish 3 ha of demonstration plots in farmers fields in arecanut growing areas of Kerala and Karnataka in association with CPCRI Kasargode. The project duration is three years.  During the year 2015-16, Rs 7.35 lakhs has been earmarked for this project.
