New seeds and farm practices to boost yields
 
CRRI develops new drought-resistant paddy seeds :
The Central Rice Research Institute (CRRI) has developed an unique drought-resistant variety of paddy seed named ‘Sahabhagi’ that can survive and produce crop even without water for over three weeks. The roots of Sahabhagi variety paddy can penetrate deeper into the soil enabling it to draw ground water. “The new paddy seed can survive without water for over three weeks”, he said.
CRRI had developed 70 high yielding and hybrid seeds, including submergence tolerant and drought resistant varieties.  “Farming systems developed by CRRI scientists can give an annual income of more than Rs one lakh per hectare.  PTI 271009
New Research Maps Critical Drought-tolerant Molecular Structure
A new research has determined the molecular structure for a drought-tolerant plant hormone called abscisic acid.
In drought conditions, plants begin to produce more of this hormone, which creates a number of changes to their physical structure. Their seeds lie dormant in the ground in order to wait out the dry period.  They slow their growth in order to conserve energy.  Tiny pores in their leaves are closed in order to prevent water from being lost.
Understanding how abscisic acid works in plants can help scientists replicate this phenomenon for farmers whose crops are suffering from drought conditions.  R&D such as this can help agricultural producers adapt to the impacts of climate change.  ANI 261009
Benefits from Flood tolerant paddy variety :
International Rice Research Institute (IRRI) has successfully completed necessary research, experiments and validation of the new flash-flood tolerant variety paddies. The experiments at the field levels showed that the varieties can sustain 12 to 16 days submergence paving the way of producing average five tonnes per hectare in flash flood prone areas. Repeated successes in getting expected production of flood- tolerant paddy in Bangladesh and India in recent years have ushered in a new era in the disaster-prone agriculture sector of the country, sub- continent and other flood- prone countries. The success was achieved through farming Swarna Sub1 along with three new Sub1 entries of BR11 Sub1, IR64 Sub1 and Sambamasuri Sub1 flood-tolerant varieties of paddy using participatory variety selection mother trial methods.

Benefits of organic Farming :
Why Organic Farming?
Organic agriculture is a safe, sustainable farming system, producing healthy crops without damage to the environment. It avoids the use of artificial chemical fertilizers and pesticides on the land, relying instead on developing a healthy, fertile soil and growing a mixture of crops. In this way, the farm remains biologically balanced, with a wide variety of beneficial insects and other wildlife to act as natural predators for crop pests and a soil full of micro-organisms and earthworms to maintain its vitality.
The avoidance of artificial chemicals means organic farmers minimize health and pollution problems. Pesticide particles travel on the wind for many miles.
Why buy organic food products?
The best reason for buying organic food is simply that it tastes extremely good, but undoubtedly there are sound health reasons for doing so too. It has been shown in some studies to have more vitamins and trace elements than conventionally grown food and, of course, it will not have been treated with noxious chemicals. There is a vast array of pesticides used in conventional agriculture, many of which are extremely toxic to humans, causing cancers as well as other illnesses.
Benefits from System of Rice Intensification (SRI)
SRI Paddy Cultivation requires less water and less expenditure gives more yields, Beneficial for small and marginal farmers.
In A.P., SRI is experimented in all the 22 districts during 2003 Kharif with encouraging results. Over 1,00,000 farmers are experimenting with this system world wide at present.
SRI Technology Uses - Less External Inputs
In SRI Paddy Cultivation Less Seed (2kg/ac) is required and fewer plants per unit area (25x25cm) whre as in general Paddy Cultivation 20kg seed is required per acre.
SRI requires less expenditure on fertilizers and plant protection chemicals.
Root Growth: In SRI System Rice Crop grows healthy in natural conditions and its root growth can be massive receives nutrients from deeper layers of the soil. Benefits of SRI Higher yields - Both grain and straw
  • Reduced duration (by 10 days)
  • Lesser chemical inputs
  • Less water requirement
  • Less chaffy grain %
Grain weight increased without change in grain size
  • Higher head rice recovery
  • Withstood cyclonic gales
  • Cold tolerance
  • Soil health improves through biological activity
New method to grow sugarcane with less water :
Now, the sugarcane industry can take to drip method for cultivating the water-intensive crop, reducing input costs and also get higher yields. Agricultural scientists have taken a cue from the SRI (System of Rice Intensification) cultivation.
The method is expected to increase yields by at least 20 per cent and reduce water consumption by 30 per cent and chemical inputs by 25 per cent. . Using the method, farmers can use a small portion of cane (bud) as seed, resulting in significant savings. Besides, the farmers could go for intercropping between the rows, generating additional income. Bl070509
New lemongrass variety brings hope for drought hit farmers
In an attempt to diversify the income of farmers, particularly those in the drought-affected areas, the Central Institute of Medicinal and Aromatic Plants (CIMAP) has come up with a new commercial variety of lemongrass plant that can be grown in places with water scarcity.
Besides being drought-resistant, the new variety is its high yield of oil that makes its cultivation more profitable than the normal variety, the scientist said. While the normal variety of lemongrass can produce about 100-125 kg of oil per hectare, the new variety can yield about 200 kg of oil per hectare. Moreover, the new variety also tends to grow faster than the normal variety. IANS 291009
Researchers develop genetic map of cow pea, Enable new varieties
A team of scientists at the University of California, Riverside have successfully developed a genetic map of the cowpea. This development will enable further research into new and more resilient varieties of this staple crop, which is grown throughout many regions of the developing world.
Mapping the cowpea is notoriously time-consuming and difficult. But now production plans of new and improved cowpea varieties can begin to take shape. Continued development and research is a key part of the Farming  plan  to prioritise research. Farming First
Protein-rich Pigeon pea hybrid 'Pushkal' developed 
A new, improved protein-rich pea, promising 40 per cent higher yields has been developed by the crop research institute.'Pushkal,' the new variety of pigeon pea, has been developed by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). "With 40 per cent higher yields than the best local varieties, Pushkal is truly the magic pea," William Dar, Director General of ICRISAT said in a report. The new hybrid thrives in drought conditions and has greater resistance to diseases. It also creates a strong root system which aids greater nitrogen fixation to keep soils fertile.
Noted agricultural scientist M S Swaminathan compared ICRISAT's success in developing 'Pushkal' to that of wheat and rice with dwarfing genes which launched a green revolution in the 1960s. TH040309
Farmer gets high yields through innovation
Combining innovation and tradition, a 56-year-old caretaker of a farm run by Aurobindo Ashram, has been using organic farming for over 34 years to get copious yields. Surendra Mohanty, who cultivates different varieties of horticultural crops, flowers, vegetables and other produce since 1975 says he had been using organic manure in the farm "as the traditional system of cultivation is time tested and is in thorough communion with nature". Use of organic manure and vegetable waste has enabled him get a healthy yield of vegetables, flowers and fruits. Waste and used polybags are being used for vegetable cultivation, obviating excavation of the Earth and are cost effective as they are cheaper than earthen pots, consumption of water is less and needs lesser space. Polybag culture is extended to promote cultivation of medicinal plants. TH 230609
