ब्रैसिका और फफूंद के अन्योन्यक्रिया का अध्ययन और उनके महत्व Less attention has been paid by researchers to phytotoxins and their role in the resistance of different Brassica species, especially in mustard (B. juncea). Pathogens are often resistant to plant defense compounds. This can happen for a variety of reasons including the plant's ability to degrade and convert defense compounds into less toxic compounds or the complete breakdown of defense compounds. This property enables the fungus to enter plant tissue and infect the plant. ब्रैसिका और फफूंद के अन्योन्यक्रिया का अध्ययन और उनके महत्व दुनिया भर में सरसो (ब्रैसिका) का महत्व इसके बीजों से निकलने वाले तेल के अतिरिक्त दैनिक भोजन के रूप में उपयोग होने से भी है। ब्रैसिका प्रजातियां अब दुनिया की 13 प्रतिशत आपूर्ति प्रदान करने वाली दूसरी सबसे बड़ी तिलहन फसल हैं। रोगजनक कवक ब्रैसिका फसलों पर हानिकारक और विनाशकारी प्रभाव डालते हैं। अधिक प्रतिरोधी किस्मों को पैदा करने या जेनेटिक इंजीनियरिंग का समुचित उपयोग करने हेतु प्रतिरोध की बेहतर समझ का होना आवश्यक है। माइक्रोबियल रोगजनकों और परजीवियों के संक्रमण का विरोध करने के लिए पौधों ने परिष्कृत रक्षा तंत्रों की एक विशाल विविधता विकसित की है जिसमें प्रेरक चयापचय पथ शामिल हैं। अरेबिडोप्सिस और कवक के बीच परस्पर क्रिया के दौरन पाए जाने वाले फाइटोटॉक्सिन पर बहुत ध्यान दिया...

मशरूम की खेती का पूरा मार्गदर्शन- एक लाभदायक कृषि व्यवसाय Activities like mushroom cultivation, bamboo production, agro-forestry, vermicomposting and agro-processing are being promoted to generate additional jobs and income for farm families. Now days Mushroom farming is one of the most profitable agri-business that you can start with a low investment and space. Mushroom cultivation is done on agricultural wastes in less area which is an attractive proposition for income generation which is leading to solution to malnutrition, pollution abatement and diversification of agriculture.  Mushroom cultivation in India is growing gradually as an alternative source of income for many people in our country, have a good scope for export.  Mushrooms are the fruiting bodies of macro fungi. Human body needs protein, carbohydrates, fats and vitamins. In India, Uttar Pradesh is the top producer of mushrooms followed by Tripura, Rajasthan & Kerala. In this article we will describe the complete cultivations method of oyster mushroom, button mushroom and paddy straw mushroom. Types of Mushrooms The mushroom industry can be divided into three main categories: edible mushrooms, medicinal mushroom products, and wild mushrooms. The button (Agaricus bisporus), oyster (Pleurotus spp.), milky (Calocybe indica) and paddy straw mushroom (Volvariella volvacea) are the three major types of used for commonly cultivated throughout India. Paddy straw mushrooms can grow in temperatures...

ट्राइकोडर्मा: टिकाऊ कृषि के लिए पर्यावरण के अनुकूल कवक The novel technologies in all areas of agriculture have improved agricultural production, but some modern practices affect the environment. The recent challenge faced by advanced farming is to achieve higher yields in environment-friendly manner. Thus, there is an immediate need to find eco-friendly solutions such as wider application of biocontrol agents. Among various types of species being used as biocontrol agents, including fungi and bacteria, fungal genus Trichoderma produces different kinds of enzymes which play a major role in biocontrol activity like degradation of cell wall, tolerance to biotic or abiotic stresses, hyphal growth etc. Many research has proved that the bio agents bring the disease suppression with no environmental hazards. Fungi in genus Trichoderma sp. have been known since 1920s for their capability to function as biocontrol agents (BCA) against plant pathogens. Trichoderma fungus are known not only for the control of plant disease but also for their capability to enhance plant growth and development, elevated reproductive ability, capacity to modify the rhizosphere. Trichoderma is capable to grow under adverse conditions, competence in the use of nutrients, strong aggressiveness against phytopathogenic fungi and efficacy in supporting plant growth and enhanced defense mechanisms. Trichoderma can work as biocontrol agents in several ways :- It may grow faster...

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 soil can improve soil chemical (e.g. pH, CEC), and physical properties (e.g. soil water retention, hydraulic conductivity). Acting as a habitat and substrate for soil microorganisms, biochar added in the soil can increase microbial activities (Pietikäinen et al., 2000). Connection between primary biochar properties (outer circle), the soil process they may influence (intermediate circle) and the soil biota (inner circle), white arrows indicate the influence between biochar properties.  Agricultural and horticultural crops have benefit from VAM on a world-wide basis. The potential application of VAM to the agriculturaland horticultural industries is great. Fungi involved in this symbiotichost root: broad spectrum of VA mycorrhizal fungi(VAMF)...
