समस्याग्रस्त मिट्टी का प्रबंधन कैसे करें For the management of problematic soils,  some general principles has to be considered for proper implementation of the reclamation measures. The total soluble salt concentrations in the root zone have to be decreased to control osmotic effects on plant growth. Maintenance of total soil moisture tension must be ensured at optimum level so that plant roots can absorb an adequate amount of water. Water flows through the soil in the direction of maximum decrease of hydraulic head and the flow velocity is proportional to the hydraulic gradient. The design and layout of drainage system are controlled by this principle. The availability of good quality water is of paramount for...

Silicone: A beneficial Ingredient for plants पोधो को अपना जीवन च्रक पूरा करने के लिए कुल १८ पोषक तत्वो की आवशकता होती हे। सिलिकॉन इन्ही में से एक आवश्यक पोषक तत्व हे। सिलिकॉन मुख्य रूप से पोधो की शक्ति और कठोरता को बढ़ाने तथा पोधो के ऊतकों में अपनी उच्च क्षमता के साथ जुडा हुवा हे। सिलिकॉन रक्षा प्रतिक्रिया तंत्र द्वारा पोधो में आने वाले रोगों के प्रति प्रतिरोधक शक्ति को बढ़ाने में सक्रिय भूमिका निभाता है। यह कई पौधों मे आनुवंशिक रूप से जैविक और अजैविक तनाव दूर करने के लिए भी लाभदायक हे। सिलिकॉन का संक्षिप्त इतिहास सिलिकॉन मिट्टी में ऑक्सीजन के बाद दूसरा सबसे ज्यादा मात्रा में पाये जाने वाला तत्व...

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...
