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 spicesduring 2008-09 and is being implemented successfully by different agencies in the subsequent years.During the year 2020-21, it is proposed to establish 53frontline demonstration plots in clusters under selected universities. Organic spices with good intrinsic qualities havegreat value for export. These demonstrations will help to develop these areas into production hubs of organic spices for export.  The balance 3 units will be allotted another SAUs/ ICAR institutes.

2 Maintenance of FLD plots on Organic farming in black pepper, established during 2018-19

The Directorate had established 13 ha of frontline demonstration plots for organic farming in Pepper during the year 2018-19, in association with State Agricultural Universities and ICAR Research Institutes. For maintenance of these plots during the current year Rs.3.25 lakhs is required.  

3. 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. It is also noticed that high level of pesticide residue are found in seed spices samples which results in export rejections especially in cumin. DASD propose to address this issue by establishing demo plots for seed spices growers on Good Agricultural Practices (GAP) in farmer participatory mode in traditional growing areas. This programme was taken up with NRCSS, Ajmer in two clusters of 25 ha each and proved very successful with the technology being accepted by the farmers, where use of pesticides was minimized with export in mind. In total, the Directorate proposes to establish85 demonstration plots of size 1 ha each for seed spices with an assistance of Rs 0.40 lakh /unit during the year 2020-21. 

4. 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 53demonstration plots of size 1 ha in aromatic plants with an assistance Rs 0.80 lakhs/unit.

5. Demonstration of on-farm water management - setting up Micro irrigation (drip irrigation)

Productivity and quality of any crop is affected by availability of optimum level of irrigation during critical stages of growth. Growth and yield parameters of spices like Black pepper, Chilli, Ginger, Turmeric and seed spices etc showed significant increase in response to irrigation. The Directorate proposes to establish 61 plots demonstrating optimum and efficient drip irrigation technique in spices. 

6. Frontline demonstration plots for Arecanut based multi species cropping system

Introduction of multi species cropping in Arecanut gardens aimed at increasing the net returns from unit area helps the farmers to withstand the fluctuating prices of Arecanut.Multiple cropping has tremendous potential to generate employment for improving quality of rural life. Multiple cropping, not only provides additional income from inter/ mixed crop and employment, it can also act as a social security against instabilityof prices of main crop. Therefore, establishing demonstration plots in few farmers’ gardens will encourage many others to follow arecanut based cropping system for the improvement of their livelihood.This Directorate had established a total of 22 demonstration plots of one hectare each in Arecanut growing areas of Kerala and Karnataka during 2007-08, 2012-13, 2016-17, 2017-18, 2018-19 and 2019-20 which were highly successful in disseminating the information to the farmers. The Directorate proposes to maintain the demonstration plots established during 2018-19 and 2019-20 for Arecanut based multispecies cropping in Karnataka & Assam during the current year as detailed below;

6.1.Multi species cropping in Arecanut Gardens in Karnataka (Nutmeg) - 2nd year maintenance

To popularize Arecanut Based Multi Species Cropping System through farmers participatory approach, the Directorate had establishedtwo demonstration plots of one hectare each on Arecanut based cropping system with Arecanut + Nutmeg + Black Pepper + Banana at farmers field in Dakshin Kannada district of Karnataka in 2019-20. The project was approved for 3 years. An amount of Rs7.44 Lakhs was utilized to establish demonstration plots in 2019-20.

6.2.   Multi species cropping in Arecanut Gardens in Karnataka (Cocoa) – 2nd year maintenance

To popularize Arecanut Based Multi Species Cropping System through farmers participatory approach, the Directorate had establishedfour demonstration plots of one hectare each on Arecanut based cropping system with Arecanut + Cocoa + Black Pepper + Banana at farmers field in Dakshin Kannada district of Karnataka in 2019-20. The project was approved for 3 years.  An amount of Rs. 4.00 Lakhs was utilized for establishment of the plot in 2019-20. 

6.3. Multi species cropping in Arecanut Gardens in Assam (3nd year maintenance)

To popularize Arecanut Based Multi Species Cropping System through farmers participatory approach among Arecanut farmers in Assam State, DASD established 2 demonstration plot of 1 ha each (Kamrup Dist.) in association with CPCRI-RRS, Kahikuchi during 2018-19. Intercrops established were Cocoa, black pepper and Banana. This project was approved for 3-year duration. During the current year the plots need to be maintained.


7. Demonstration of effective and eco-friendly management of white-grub using Entomopathogenic nematode (EPN) in Arecanut (3rdyear maintenance)

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. Usually the grubs are managed with application of high dose of pesticides applied frequently which is deleterious to ecosystem. EPNs are identified to be effective and environmental friendly alternative to manage white grubs by CPCRI, Kasargod. To popularize ecofriendly management of whitegrub using EPNs, DASD had established 4 demonstration plots of one acre each in farmers fields in Dakshina Kannada and Udupi districts of Karnataka in association with CPCRI Kasargod. This was a three year programme , sanctioned in 2018-19.

8. Demonstration of Arecanut Dwarf Hybrids (2ndyear maintenance)

Arecanut tall varieties even though possess high yield potential, are frequently prone to wind damage and sun-scorching and also become difficult to manage. The tall nature of the palm hinders various operations like spraying and harvesting which are quite labour intensive and cumbersome. Dwarf hybrids with high yield potential will directly benefit the growers by way of enhanced returns and reduced cost of various cultural operations like harvesting, spraying and also without causing much damages to palms due to sun-scorching and heavy wind and gives mechanical support to stem. Therefore, the Directorateestablished two demonstration plots of arecanut dwarf hybrids in farmer’s fields (2 units of 0.5 acre each) to promote its advantages among progressive farmers.The project was approved for 3 years in 2019-20 with a total budget of Rs. 9.90 Lakhs. 

9. Participatory Demonstration Plots of Cinnamon intercropping in coconut (3rdyear assistance)

DASD in association with CPCRI Kasargodhad established demonstration plots of high density intercropping of cinnamon in coconut plantationsof Kasargod District, Kerala through participatory approach during 2018-19, to promote progressive farmers in adopting this system. The project was approved for 3 years.  Three demonstration plots of one acre each were established in three different locations. 

10. Demonstration of arecanut fruit rot disease management using Mandipropamid fungicide

Fruit rot (‘Koleroga’ or Mahali) is counted as one of the most dreaded disease of arecanutwhich has resulted in 40-65 % yield loss in different district of Kerala and Karnataka during 2018-19. Based on trials conducted by ICAR-CPCRI, it was concluded that the use of Mandipropamid 23.3%SC @ 0.5% spray is the most effective method to control the disease in comparison with conventional methods. The DASD propose to demonstrate integrated disease management practices for management of arecanut fruit rot using oomycetes specific fungicide Mandipropamid 23.3%SC in the selected farmers field of Kasaragod (Kerala) andDakshina Kannada (Karnataka) districts. The Programme will be implemented by the ICAR-CPCRI Kasargod.  FLDs will be established in 3 units (of one acre each) in the disease prone area of selected districts. Transfer of technology programmes like trainings, field days etc also will be conducted as apart of FLD. The total project cost estimated for 3 years is Rs.11.97 Lakhs. 


11. Technology dissemination through FLD for HDP of grafted Bush pepper under shade net structure

High Density Planting ofbush pepper assures higher productivity levels per unit area with the adoption of high-tech irrigation technology under shade net structures. This technology is suitable for small scale holdings to earn higher economic returns per unit area.Preliminary results of HDP of grafted bush pepper units in Farmers’ fields established by ICAR-CCARI, Goa indicated higher yield potential of black pepper per unit area. One-year old bush pepper grafts have recorded 200 -250g dry pepper corns per plant. During the recently held national seminar on spices at CCARI, Goa also the importance of bush pepper technology to increase income from unit area was highlighted and it was suggested that this technology may be given wide publicity so that farmers with lesser land resources can adopt this as a profitable enterprise. To promote this potential technology among farmers DASD propose to establish FLDs in different locations as detailed below. This will serve as a model demonstration plot for marginal farmers in the nearby areas.

11.​​​​​​​1. FLD for HDP of grafted Bush pepper under shade net structure under CCARI-Old Goa

Five FLDs ,two each in North Goa and South Goa Districts in farmers’ fields and one OFD unit in the Institute’s Farm at Old Goa, were established by DASD in association with ICAR-Central Coastal Agricultural Research Institute, Old Goa during 2018-19. Each unit consistShade net structures with 50 % green shade net with 300 Sq.m area (20m X 15m) accommodating 1000 bush pepper grafts (at 50cm x 40 cm spacing in paired row with 60cm). The bush pepper plants have started fruiting and is showing promising results. These units need to be maintained for the third year.

​​​​​​​11.2. FLD for HDP of grafted Bush pepper under shade net structure at HRS Pechiparai, Tamil Nadu

One FLD will be established at HRS Pechiparai, TNAU in shadenet structure of 320 sq m area (16 m X 20 m) with fertigation,accommodating 640 bush pepper grafts (1m X1m spacing). The total project cost estimated for establishment of the demonstration unit is Rs. 4.00 Lakhs.
