The SRI rice cultivation method developed in Madagascar not only produces a 15 – 20% higher yield than the conventional rice cultivation method, but also saves 35 – 40% of the water requirement. The crop also ripens for 15 – 16 days. The SRI method of rice cultivation is very suitable in the low lying area of Tripura, Garo Hills of Meghalaya, Pasighat of Arunachal Pradesh and other low lying areas of NEH region. Rice productivity in the region (1.6 tons/ha) is much lower than the national average (2 tons/ha).
The research results showed that rice productivity can be increased by 15-20% with SRI rice culture and ICM (Integrated Crop Management - an intermediate practice between SRI and CRC) in the region. The state of Tripura has made significant progress in SRI and about 20% of the paddy area in the state is already under SRI/ICM. The ICM rice cultivation method developed by IRRI, Philippines is also a superior rice cultivation method compared to the conventional method.
ICM method of rice cultivation can be used in low altitude, medium altitude during kharif as well as boro season. A number of crops like turmeric, ginger, groundnut, soybean, taro were cultivated with fruit trees like Assam lemon, Khasi Mandarin and Guava to develop a suitable agro-horticulture system in the region. The size of each sample was limited to 1 ha in order to represent the majority of the farming community in the region.
The availability of fruits can be extended to 47 days by planting in the month of November under UVS polyethylene tunnels.

COLOCASIA
DISEASE PROTECTION TECHNOLOGIES MUSHROOM
Pleurotus sajor caju PSC 04 has been identified for summer cultivation. This strain yields 972 g/kg dry paddy straw. Hot water treatment (80°C for 20 minutes) and chemical sterilization technique (Formalin 500 ppm + Carbendazim 75 ppm soaking for 18 hours) were found equally effective for pretreatment of paddy straw.
GROUNDNUT
Standardization of doses of herbal substances, namely anonin and karanjin against cob borer and stem borer of maize, aphids, diamondback moth, cabbage butterfly, blister beetle and red cotton bug. Beauveria bassiana @ 3.5 g/liter against blister beetle and pod weevil, Metarrhizium anisopliae @ 2.5-3g/liter against white grub and Verticillium lecanii @ 3g/liter against white-backed planthopper proved effective. Potential bioagents namely Trichogramma japonicum @ 50,000/ha (5-6 emissions from 30 DAT) against yellow stem borer of rice and Coccinella septumpunctata against mustard aphid were standardized for their use in IPM.
Technologies
Developed for Soil Health Management
Applying 250-500 kg lime/ha in furrows for each crop in the sequence can optimize the productivity of maize, soybean, groundnut and wheat, which are almost 15-20 times less than applying lime. Fertilizer application can be reduced to 50% by furrow application of FYM and lime to obtain optimum crop yield. A ready-made lime to achieve the target soil pH (5.5) has been developed taking into account soil organic matter, clay content and pH, to be approved by the soil testing laboratory for liming acid soils.
Soil need for lime to reach pH 5.5, depending on pH, organic matter and clay content in the soil (t/ha)*.
Micro Rain Water Harvesting Structure for Hills - Jalkund
Excavating the 4 x3 x 1 pit at a selected location (preferably on a hilltop/highland) before the onset of monsoon. The bed and sides of the kund should be leveled by removing rocks, stones or other protrusions, which could otherwise damage the lining material. The interior walls, including the underside of the wall, should be smoothed by plastering with a mixture of clay and cow manure in the ratio 5:1.
The Agri-film foil must be laid down in such a way that it touches the bottom and the walls loosely and uniformly and extends to a width of approx. 50 cm around the customer's length and width. The blades are mounted on two sets of cones to perform weeding operations between the weed rows without bending the operator's position, reducing wear. Since the establishment of ICAR Research Complex for NEH region at Barapani, Meghalaya has been working on two major research projects on (i) “Alternative Farming System to replace Jhuming” at Byrnihat in 1975 and (ii) “Micro-watershed based land use planning for Hills ” in 1983 in Umiam (Barapani) known as Farming.
Among them are promising and most suitable systems like Agro-pastoral farming system, Agri-horti-silvipastoral farming system, Livestock-based farming system, Horticulture-based land use system, Horti-silvi farming system established with integration of livestock system in most of the cases and details of package and practice crops, vegetables on the mountain terrace and other integrated component of animals (cows, pigs, goats, fish), fodder, etc. Identification of critical areas within the watershed: Assume significant importance for their effective treatment to reduce the sediment and pollutant load at the outlet of the watershed. Only a few critical areas within the watershed are responsible for a disproportionate amount of pollution.
Plasmid profiles of the isolated bacteria are also analyzed and studied for their role in diseases in animals and livestock. Therefore, the Animal Production of the institute developed upgraded pig by crossing Khasi local with exotic Hampshire pig. The aim of the present study was to estimate the macro- and micro-mineral content of soil, feed and serum of dairy cattle and to establish the soil-plant-animal continuum in subtropical hilly areas of Mizoram, a hilly state of northeastern India. .
Soil (n=96), feed (n=96) and blood serum samples from dairy cattle (n=120) were collected from randomly selected small dairy farms in all eight districts of the country. Inventorying the state of minerals in forage and animals in an area would provide deep insight into the development of site-specific technologies and the development of forage and animal production strategies. Our results showed that most cattle are deficient in Ca, P, K, Mg, Co, Cu, Mn and Zn.
During the months of May to November, about 90% of DM feedstock was provided through perennial grasses and legumes in the cut-and-carry system. Given the excellent climatic conditions available in this part of the country for rearing crossbred dairy animals, the feeding strategy has been developed to maximize growth rates in the later part of the growing period by providing finishing rations .
