Vermi compost unit Vermicomposting is a simple biotechnological process of composting, in which certain species of earthworms are used to enhance the process of waste conversion and produce a better end product i.e. vermi cast. Vermicomposting or vermi cast is an organic manure prepared from the bio-agro, city, kitchen wastes and cow dung by the earthworms and a rich source of plant nutrients. The vermiculture technology has potential of nutrient supply in an environment friendly farming system.
Earthworm species: Eisenia fetida.
Method: In a simple vermicomposting
method the crop waste material is mixed with fresh cow dung in the preparation of 4 : 1 and water is sprinkled to keep 30% moisture of the mixture. The mixture is left for 10-15 days. The partial decomposition starts in waste mixed material. Thereafter, the bed with 3m x 1m x 0.3m size is prepared in a shed. Partial decomposed waste material is put in the bed and left earthworms in it. Then it is covered with gunny bags or mulch material. Water is sprinkled timely to maintained the temperature of the bed about 35oC throughout the process. Earthworms start feeding the material and within 45-60 days the material is turned into dark brown vermi cast. The vermi cast is ready to be applied in the field.

These are ber syrup, ber candy, lemon pickle, fruit pickle, aonla pickle. In this fruit processing unit the products are prepared according to need and requirement of farmers and farm women.
Water harvesting in its broadest sense can be defined as the “collection of runoff water for its productive use”. Runoff water may be harvested from roofs and ground surfaces as well as from intermittent or ephemeral water courses. Water harvesting techniques, which harvest runoff from roofs or ground surfaces fall under the term “Rainwater Harvesting”. The objective and reason to utilize concepts and techniques of rainwater harvesting is to optimize the use of the available rainfall on any given location. KVK, Pali has constructed a rainwater harvesting structure of dimensions 10m X 10m X 4m under the project entitled “Livelihood and nutritional security through rain water harvesting in arid zone of Rajasthan” which is externally funded by NABARD. The rainwater structure is located at a point where water from catchment area gathers and the structure is filled in single rain. This structure holds enough water for the entire need of farm. The rainwater harvesting structure is also being used for fish and duck rearing. KVK, Pali has established drip and micro irrigation setup on its farm and is using rainwater from the rainwater harvesting structure for irrigation of its field crops. The rainwater harvesting structure is serving as a demonstration as well as motivation unit for the farmers of surrounding villages and district area. It is also serving as a facility for technical training programme of extension functionaries and farmers, informational support and capacity building in several ways.
At KVK farm 500 buds of Napier grass (APBN-1) have been planted with good growth and given to approching farmers for cultivation at their fields. Napier grass is also called as Elephant Grass due to its tallness and vigorous vegetative growth. Hybrid Napier is a perennial grass (Elephant grass X Bajra) which can be retained on field for 2-3 years. Compared to Napier grass, Hybrid Napier produces numerous leaves. It has larger leaves, softer and less persistent hairs of leaf blades and sheaths and less sharp leaf edges. The stems are also less fibrous than Napier. The tillers are more numerous and grow faster. The grass grows throughout the year in the tropics. The optimum temperature is about 31° C. There are many Hybrid Napier varieties like APBN-1, NB-21, CO-3 and CO-4. The napier grass has high nutritive value as Dry matter (16.20 %), Crude Protein (9.38 %), Calcium (0.88 %), Phosphorus (0.24 %), Oxalates (2.97 %) and Digestibility (58.00 %). Leaves (Foliages) are larger and greener, sheaths are softer, and margins are less serrated; so the herbage is more palatable. It is juicier and succulent at all stages of growth. It is less fibrous and more acceptable.
The objective of seed processing is to achieve clean, pure seeds of high physiological quality (germinability) which can be stored and easily handled during succeeding processes, such as pr etreatment, transport and sowing. Processing includes a number of handling procedures, where applicability differs e.g. according to seed type, condition of the fruits or seeds at collection and potential storage period. Keeping the above facts in mind a Seed Grading Unit has been established under National Horticulture Mission at KVK Pali. The project leads to the development of new facilities and procedures of seed grading and processing with the following objectives.
- To demonstrate the latest improved cleaning and grading technologies of seeds to the farmers with a view to reduce the time gap between technology generation and its adoption.
- To increase awareness about seed grading and packaging technologies of crops through demonstration at KVK farm and at farmers fields.
- To generate self-employment and capacity building among farmers by adoption of the said units
- To increase area under various crops of improved variety through proper graded and treated seeds
The following crops can be graded by the Seed Grading Unit:
- To provide easy and timely improved quality and quantity plant materials to farming community in arid and semi- arid region.
- To increase the number of plants and preserve the essential characters of plants for developing orchard in region.
- To generate revenue and improve the economic condition of farmers.
- To generate self-employment capability among entrepreneurs through nursery raising in region.
The following plants of different varieties have been planted in the nursery and their saplings are prepared throughout the year.
Gunda, Aloe vera, Bargad (Bud), Drumstick, Fig, Agave, Kela, Lemon, Mehandi, Parkensonia, Ralia, Napier grass, Neem, Neem (Meetha), Shatavar, Papaya, Podina, Pomegranate, Chameli, Chandni, Bogenvalia, Champa plant (Deshi), Champa plant (English), Hazara, Harsingar, Nagdon, Keli, Gudhal, Kevda, Bamboo, Lilly, Mogra, Rangoon creeper, Rose, Sadabahar, Azolla etc.
Azolla is a floating fern and belongs to the family of Azollaceae. Azolla hosts a symbiotic blue green algae, Anabaena azollae, which is responsible for the fixation and assimilation of atmospheric nitrogen. Azolla, in turn, provides the carbon source and favourable environment for the growth and development of the algae. It is this unique symbiotic relationship that makes azolla a wonderful plant with high protein content. Azolla is easy to cultivate and can be used as an ideal feed for cattle, fish, pigs and poultry, and also is of value as a bio-fertilizer.
NCOF, Ghaziabad, launched waste decomposer culture which is proving as miracle all over the country. It is used for quick composting from organic waste, soil health improvement and as plant protection agent. It is a consortium of micro organism extracted from desi cow dung. KVK, Pali is widely publicizing and demonstrating waste decomposer in Rajasthan particularity in Pali District. A large number of Pali and nearby district farmers have applied it on different crops in their fields and very much satisfied with its performance since it is an organic product. There is a nominal one time cost for procuring it and afterwards farmers can reproduce it on their on as much quantity they want.
KVK, Pali has procured various latest farm implements under government’s Sub Mission on Agricultural Mechanization. These implements will be utilized at KVK farm as well as for demonstration to farmers of Pali and surrounding districts. These implements will be useful in the sense of saving time, reducing costs and increasing work efficiency.
KVK, Pali has a rabbitry unit of where it is having 50 rabbits.
KVK, Pali has a Low Cost Polyhouse unit.
