Preface:- 

Green Revolution started in late 1960s refers to a series of research, development, and technology transfer initiatives that increased agriculture production worldwide, particularly in the developing world. Agriculture in India has a significant history. Today, India ranks second worldwide in farm output. Agriculture with its allied sectors like fishery and animal husbandry, is the largest livelihood provider in India. It also contributes a significant figure (nearly 17%) to the Gross Domestic Product (GDP). Sustainable agriculture and environmentally sustainable technologies such as soil conservation, sustainable natural resource management and biodiversity protection, are essential for holistic rural development. It is after the green revolution and white revolution that India has turned into a self sustainable nation from an import dependent country.

 

Background of study:- 

In the Dangs there is high pressure on the agriculture lands, since majority of the land is forestland (59%) and only a limited amount of land is available for agriculture to support a growing population. Another limiting factor is the fact that 68% of the agriculture land is situated on a slope. There is very little space for infrastructural development or expansion of agricultural lands. Sole dependency on rain fed agriculture, insufficient agricultural land, low agricultural productivity and a lack of alternative employment sources are the main problems in this region. Agriculture is the main source of livelihood; 85% of the population is either a cultivator or employed as an agricultural labourer. The whole Dang district has very limited opportunities for irrigation, since there is a scarcity of flat land. The cropping pattern of the Dangs is conditioned to rainfed nature of agriculture and lack of irrigation. Most of the cultivation is being done during monsoon and Paddy is the main crop. Pesticides and chemical fertilizer are not commonly used; even farmers with bigger land holdings do not use fertilizers in the production of rice. In this context it is interesting to note that the Dangs has the lowest ranking amongst all districts in Gujarat on the percentage of gross irrigated area and fertilizer consumption, only 0.53% is irrigated and only 1.20 kg fertilizer is being used per ha. Even though in agriculture productivity and agricultural production per household, Dangs ranking is 8th and 12th (7247 Rs/ha. and 1301 Rs/capita). This provides lots of opportunity for taking up organic farming in the district.

Main reason for the deteriorating quality of land is erosion of the top soil layer due to heavy rainfall. The practice of burning timber for improving soil condition, locally name as “adar”, further enforces deforestation. Hence land is prone to erosion and it also reduces soil fertility due to loosening the top fertile layer of soil.

 

Traditional method of paddy farming:- 

 Here paddy farming is done by adar method. In this method timber is allow to burn on soil in order to kill the bacteria. Also seedlings are not prepare properly and transplanting is not done properly, Use of seed per ha is also high.

 

Disadvantage of adar:- 

1. Less productivity
2. Pressure on forest
3. Increase in soil erosion
4. High cost of production
5. More requirement of water.

Intervention through IWMP- 

After analysing the situation and coordinating with Aga Khan Rural Support Programme (AKRSP) it was decided to implement System of Rice Intensification (SRI) tech. for paddy farming. AKRSP is already working in this region to promote SRI technology for augmenting agriculture production.

Method of SRI:- 

1. Seed treatment:- 

SRI technique was developed in 1983 by the French Jesuit Father Henri de Laulanié in Madagascar. However the reach of this technology was very limited until last decade. The main principles of this technology are application of minimum quantity of water and individual transplantation of very young seedlings in a square pattern. Here, seed is treated in brine solution before using for seedling preparation. The brine solution is concentrated to such extend that a potato or egg can float in the solution. Once the solution is prepared seed is poured in it. The seeds which float on water are not used for seedling preparation and thus rejected. The good quality seed is taken out from water & then washed with clean water. Then this seed is tightly packed in cloth bag & put it for 1 day until sprouts come out from the bag.

2. Seedling Preparation:- 

For seedling preparation the above sprouted seeds are used. Raised bed which is being treated with vermi-compost is prepared. These seed are spread on this bed.

 

3. Land Preparation:- 

Land preparation is done by normal method. The only difference in this method is that depth of water impounding is less as compared to traditional method.

 

4. Transplanting:- 

Seedlings of 12-15 days are transplanted as root growth is fast & more pillars are developed. During transplanting row to row & plant to plant distance is maintained as 25 × 25 cm.

 

5. Weeding:- 

As proper spacing is being maintained, weeding operation is done very easily. Here, Cono-weeder is used for weeding operation. It helps in easy weeding operation & land in being pulverised during operation so aeration is done. It also helps in proper growth of paddy.

 

Advantages of SRI:- 

1. Less cost of production
2. Less use of water i.e. water conservation
3. High productivity -around 2-3 times increase in production

Detail of Work:- 

In District Dang there are total 109 beneficiaries of SRI intervention. The expenditure for this activity was Rs. 1496 per beneficiary per acre. Somabhai Pandubhai Pawar of Nirgundmal village in IWMP- 6 (Shamgahan Project) is among one of the farmers selected for SRI demonstration in the village. According to him the production of paddy has increased by 2-3 times. Earlier the production was 300 kg and now after practising SRI techniques the total production is nearly 750 kg. Considering the market price of paddy as Rs. 18 per kg, the increase in gross revenue is nearly Rs 8100 per acre.

Effect of study:- 

Likewise Green Revolution, this tech has found to be very useful in increasing livelihood of farmers. This technology has proved to be a boon for major rice producing places in India. Not only in Dangs but also in various other eastern parts of India, this SRI technology is being practices for last few years and expanding its reach considerably. With this remarkable achievement in rice cultivation other farmers are also accepting this technology. For promotion and as a part of extension service various training are also being organised by DWDU in coordination with KVKs and NGOs. For better result seed treatment and seed spacing should be maintained properly. To monitor the practices all extension departments along with DWDU is constantly engaged in training and capacity building activities of the farmers.
