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...

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...

कृषि‍ फसलों में फास्फोरस उपयोग दक्षता बढ़ाने के लिए रणनीतियां Phosphorus (P), an essential macronutrient for all living organisms, is a vital component for building blocks of genes and chromosomes. In plants, it plays a role in virtually all biochemical processes that involve energy transfer.  It is a constituent of adenosine triphosphate (ATP), which is often termed as ‘energy currency’ of the plant cell. In plant, P is essential for photosynthesis, respiration and root growth, flowering, fruiting, seed setting and seed yield. The total P content in agricultural crops ranges from 0.1 to 0.5%. Phosphorus is taken up by the plant as primary orthophosphate ion ( H2PO4- ) but it is also...

मृदा स्वास्थ्य को नि‍रंतर बनाए रखने के लिए मिट्टी कंडीशनर महत्वपूर्ण कारक  Soil conditioners as a source of plant nutrients has been found beneficial in improving Physical, Chemical and Biological conditions of soil, thereby increased productivity of crops. If the soil had very low pH, P and extractable Si then it is necessary to use soil conditioners for improving soil pH and some elements such as P and Si. Farmers can adopt this technology to improve the crop production.  A soil conditioner is a product which is added to soil to improve the soil’s physical qualities, especially its ability to provide nutrition for plants. In general usage the term soil conditioner is often...

Benefits of using bio-fertilizers in Vegetables and other crops. आज कृषि उत्पादन को लगातार बढ़ाना कृषि वैज्ञानिकों के सामने सबसे बड़ी चुनौती है। सघन खेती से मृदा में पोषक तत्व धीरे-धीरे कम होते जा रहे हैं। इस कमी को रासायनिक उर्वरकों के प्रयोग से पूरा किया जाता है। अधिकांश किसान संतृप्त मात्रा में रासायनिक खाद के उपयोग के बावजूद इष्टतम उत्पादन लेने से वंचित हैं और रासायनिक उर्वरकों के प्रयोग से होने वाला लाभ घटता जा रहा है। रासायनिक खाद के उपयोग का मृदा स्वास्थ्य पर भी विपरीत असर दिखाई पड़ रहा है। फसलों द्वारा भूमि से लिये जाने वाले प्राथमिक मुख्य पोषक तत्वों जैसे  नत्रजन, सुपर फास्फेट एवं पोटाश में...

मिट्टी की उर्वरता का संरक्षण और जैविक पदार्थों की भूमिका Maintenance of soil fertility is a great problem to our farmers. Cultivation of particular crop year after year in the same field decreases the soil fertility. To increase the soil fertility, it is necessary to check the loss of nutrient and to increase the nutrient content of soil. The following things must be properly followed for increasing the fertility of soil. Proper use of land improve soil fertility Good yield of crop is not possible if we cultivate any crop in any land. So it is necessary to select the crop which is suitable for a particular land. Practical experience will be helpful...

फसल उत्पादन में महत्वपूर्ण भूमिका और नगण्‍य अावश्यकता वाले शुक्ष्‍म तत्‍व (ट्रेस एलीमेंट्स)  For proper growth and development of plants, require essential nutrients which are categorized in two groups on the basis of amount of requirement in plant body as macronutrients (more required) and micronutrients / trace elements (less required). Deficiency of trace elements in soil inhibits plants to complete its life cycle properly which ultimately affect on crop production. Therefore, farmers should give more emphasis on this aspect and extension agency should provide more information on trace elements to farmers for their awareness and better knowledge. Plants require food for growth and development. At the beginning of the new phase of the life...

ताजे खजूर फल गुच्‍छों के अधि‍क उत्पादन हेतु, तेल खजूर (आयल पॉम) में सर्वोत्तम उर्वरक प्रबंधन वि‍धि‍यॉं। Oil palm (Elaeis guineensis Jacq.) is the highest edible oil yielding perennial crop producing two types of oil i.e. crude palm oil and palm kernel oil which are used for domestic and industrial purposes. It produces about 4 to 6 tonnes of crude palm oil and 0.4 to 0.6 tonnes of palm kernel oil per hectare per year during its productive life span from 4th to 30th years. Oil Palm is a heavy feeder and it requires a balanced and adequate supply of macro and micro-nutrients for growth and yield. Fertilizer requirement of Palm Recommended nutrient...

तेल पाम वृक्षारोपण में मिट्टी के नमूने एकत्र करने के लिए सटीक विधि Oil palm is a heavy feeder of nutrients as it produces a very high biomass. Input management plays a major role in plantation crops as the crop remains in the field for a longer period of time. In oil palm plantations fertilizer management proved to play a major role in defining yield potential in terms of Fresh Fruit Bunches (FFB). Soil analysis is an effective method to determine plant nutritional status for suitable fertilizer application.  This includes the collection of representative sample from the soil, estimation of nutrient status and other parameters, calibration and interpretation of analytical results...
