सेलाइन (खारा) मिट्टी के सुधार की तकनीक Accumulation of excess salts in the root zone resulting in a partial or complete loss of soil productivity is a worldwide problem. Soil salinity has caused heavy loss of national wealth in India. Out of 329 million hectares of land in the country, about 175 million ha (53 %) is suffering from degradation. The extent of this problem area as given by different sources varies from 8.56 M ha to 10.9 M ha. According to Central Soil Salinity Research Institute (CSSRI), Karnal, 1.7 M ha of land is affected by salinity among the 6.7 M ha of salt affected land. World as a whole is...

सिलिकॉन तत्‍व: पौधों में तनाव सहिष्णुता में सुधार के लिए लाभकारी घटक The beneficial effects of Si are mainly associated with its high deposition in plant tissues, enhancing their strength and rigidity. However, Si might play an active role in enhancing host resistance to plant diseases by stimulating defense reaction mechanisms. Because many plants are not able to accumulate Si at high enough levels to be beneficial, genetically manipulating the Si uptake capacity of the root might help plants to accumulate more Si and, hence, improve their ability to overcome biotic and abiotic stresses. A brief history of silicon in plants Silicon (Si) is the second most abundant element after oxygen in soil. Silicon...

धान की सीधे बीज (डायरेक्ट सीडेड) से बुआई: पानी की खपत और श्रम को कम करने के लिए एक दृष्टिकोण In India, rice field covers an area of 43.94 million hectares (mha) with production of 106.54 mt and has the share of 21% in global rice production during 2013-14. Of the total rice area, 49.5% (22 mha) is irrigated, 13.5% (6 mha) is upland, and 32.4% (14.4 mha) is rainfed lowland. In Asia, 90% of fresh water has been exploited by agriculture and more than 50% is utilized to irrigate rice. More than 75% of the rice supply comes from 79 mha of irrigated land. Therefore, food security is challenged and threatened...

मुर्गी पालन की समस्याएं: एक विश्लेषण Poultry farming is one of the most fertile areas to ease out the pressure of population on crop cultivation. Among the livestock based vocations, poultry farming occupies a pivotal position due to its enormous potential to bring about rapid economic growth with low input investment. Poultry farming is one of the fastest growing segments of agriculture sector in India with an average growth rate of 6 percent in egg production and 12 percent in broiler production per annum. As a result, India is now the world’s third largest egg producer after China and USA with 50000 million eggs worth Rs. 6300 crores. India stands fourth position (after...

मिट्टी में बायोकर और मायकोर्हाइज़े की परस्पर क्रिया Agricultural intensification transfer carbon (C) to the atmosphere in the form of carbon dioxide (CO2), thereby reducing ecosystem C pools. Agriculture contributes 10–12% of the total global anthropogenic greenhouse gas emissions. Diminishing increased levels of CO2 in the atmosphere by pyrolysis to convert biomass into biochar, which stabilizes the carbon (C) that is then applied to soil. Biochar withhigh concentrations of carbon that can be rather recalcitrant to decomposition, it stably sequestercarbon. The immediate beneficial effects of biochar additions for nutrient availability are largely due to higher potassium, phosphorus, and zinc availability, and to a lesser extent, calcium and copper. The presence of biochar in the...
