कृषि उत्पादाेे का मूल्य संर्वधन: लाभ कमाने की सदाबहार तकनीक Agriculture forms the backbone of Indian economy and even though there has been large industrialization in last 60 years, agriculture still occupies a place of importance. Agriculture has abled to provide us more or less food security, but, still failed in providing nutritional security. Value addition is one of important components of nutritional security. Sometimes surplus production is the cause of lower price of produce in market. One way to solve the problem is crop diversification which is responsible for a viable market system, creates opportunity to earn more as well as strong step toward nutritional security.  Another step is value addition of...

ग्रीनहाउस गैस उत्पादन पर मानवकृत गतिविधियों और कृषि कार्यो का प्रभाव Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gas­es, aerosols (small particles), and cloudiness. Human activities like burning of fossil fuels (coal, oil and natural gas), deforestation and various agricultural and industrial practices, are altering the composition of the atmosphere and contributing to climate change.  These human activities have led to increased atmospheric concentrations of a number of greenhouse gases (GHGs), including carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and ozone in the lower part of the atmosphere. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to...

कार्बन ट्रेडिंग पर अंतर्राष्ट्रीय सम्मेलन और वैश्विक पहल Carbon is the common denominator in all polluting gases that cause global warming. Carbon dioxide is the gas most commonly thought of as a greenhouse gas. It is responsible for about half of the atmospheric heat retained by trace gasses. It is produced primarily by burning of fossils fuels and deforestation accompanied by burning and bio-degradation of biomass.  It is estimated that if the CO2 increases in the atmosphere at the present rate and no positive efforts are pursued, the level of CO2 in the atmosphere would go up to 800-1000 ppm by the end of current century. Which may create havoc for all living...

मैग्नीशियम: फसल उत्पादन का एक भूलाा हुआ पोषक तत्व Magnesium nutrition of plants is frequently overlooked and shortages will adversely impact plant growth. Many essential plant functions require adequate Mg supplies, the most visible being its role in root formation, chlorophyll, and photosynthesis. Many less visible reactions are also dependent on an adequate supply of Mg. This review briefly summarizes some of the essential roles of Mg for plants. Magnesium was discovered by Sir Humphrey Davy in 1808 and essentiality for plant life was proved by Willstatter in 1906. Magnesium has a number of key functions in plants. Particular metabolic processes and reactions that are influenced by Mg include photo-phosphorylation such as ATP...

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...
