चावल पारिस्थितिक तंत्र का वि‍ध्वंसक कीट -  ब्राउन प्लांटहोपर Rice is a primary staple food crop for billions of people worldwide. To ensure global food security for continuing population growth, it is vital to control the various insect pests that damage rice (Normile, 2008). Among the herbivorous insects, Brown Planthopper (BPH), Nilaparvata lugens (Stal) to be considered as the devastating pest of rice, causing much distress among rice growers in the tropics, thereby posing serious threat to the national food security.  Both nymphs and adults of brown planthopper are mostly found at the base of the tillers, where shade and humidity is high, providing suitable microclimate for their multiplication. It can reduce the yield upto...

कीटनाशकाेे का वि‍वेकपूर्ण उपयोग सतत कृषि के लिए समय की आवश्यकता Although, pesticides offer one of the best means of controlling insect-pests and diseases of plant, pesticides are poisonous and their indiscriminate and unlimited use may result in ecological imbalance resulting in pest resurgence, aggravation of minor pests, pesticides resistance, environmental pollution, poising serious health hazards to man and animals.  Only a small amount of the pesticides (less than 1%) applied to a crop reaches to the target pests and the remaining more than 99% contaminates soil, air, water, food, feed etc.  However, if used judiciously such problems do not  occur. Most of the problems related to pesticides use have occurred due to misuse...

Parasitic Dodder (Ruscuta Reflexa) and its control परजीवी खरपतवार कृषि के लिए एक गंभीर समस्या है जिनको नियंत्रित करने के लिए उपलब्ध साधनों की प्रभावकारिता कम होती जा रही है।  परजीवी खरपतवार अपना भोजन बनाने और अपना जीवन चक्र पूरा करने के लिए दूसरी फसलों पर निर्भर रहते हैं। जैसे अमरबैल रिजके में, रूखड़ी मक्का और ज्वार में, औरोबंकी सरसों पर निर्भर रहती है। सबसे अधिक आर्थिक रूप से हानिकारक परजीवी खरपतवार रूखड़ी,  औरोबंकी और अमरबेल हैं। अमरबेल तना परजीवी पौधा है जो फसलों या वृक्षों पर अवांछित रूप से उगकर हानि पहुँचाता है। मुख्य रूप से रिजके में इसकी गंभीर समस्या देखी गई है परन्तु अलसी, चुकन्दर, मिर्ची, प्याज, गाजर, सूरजमुखी, रामतिल,...

आम में कायि‍क विकार, भारतीय आम उत्पादकों के लिए एक बड़ी परेशानी Mango orchards in India are facing declining growth in recent time leading to decrease in yield and productivity. Although a number of factors are responsible for mango yield decline, yet physiological disorders play more devastating and vital role. As a result, mango growers are losing their faith and interest in mango orchards and trying to shift their cultivation practices from mango to other crops. Mango (Mangifera indica L.) is the choicest fruit of India in terms of production, economy and acceptability by the consumers. In India it covers around 36 per cent of total fruits growing area. Owing to delicious taste,...

रासायनि‍क रूप से वि‍कृत भारतीय मृदाओं का प्रबन्‍धन।  Chemical deterioration of soils is a type of soil degradation that involves loss of nutrients or organic matter, salinity, acidification, soil pollution and fertility decline. The removal of nutrients reduces the capacity of soils to support plant growth and crop production and causes acidification. In arid and semi-arid areas problems can arise due to accumulation of salts, which impedes the entry of water in plant roots. Chemical deterioration of soils is often also due to agricultural over exploitation, relying solely on replenishing nutrient losses through harvesting by artificial chemical fertilizers. Indiscriminate irrigation for getting higher yield has led to water logging; nutrient losses and increased salinity of lands threatened the sustainability of crop yields. The increasing salinization of...

टिकाऊ फसल उत्पादन में मृदा भौति‍क दबाव और उनके प्रबंधन के विकल्प Enhanced soil productivity and assured sustainability are the two major concerns to feed the increasing population of the modernized world. Scientific planning and management practices for further enhancement and sustaining of the productive potential of soils, however, require a proper understanding of the factors limiting its productivity.  About 1704.68 lakh ha of land areas of our country at present is affected by various soil problems. A number of soil physical constraints result into unfavorable soil environment for nutrient availability and utilization by crops. The physical fertility describes state of soil in respect of flow of water and air, thermal regimes and...

ऊंची सुरंग: पुष्प फसल उत्पादन के लिए वरदान Solar radiation, temperature and precipitation are the main drivers of crop growth, therefore agriculture has always been highly dependent on climate patterns and variations. To overcome all these problems related to climate change, we have to work on Structural and functional design of different Protected structures like Greenhouse, Polyhouse, High tunnels, Low tunnels, shade net house and Low cost environment control greenhouse. Among all these High tunnel is really boon for floral crop production. High tunnels are passively vented, solar greenhouses that are used to lengthen the production and marketing season of cut flowers. No artificial heating/cooling or ventilation system is used within the high...

Azolla: An awesome and amazing Plant अजोला  तेजी से बढ़ने वाली एक प्रकार की जलीय फर्न है, जो  पानी की सतह पर तैरती रहती है। धान की फसल में नील हरित काई की तरह अजोला को भी हरी खाद के रूप में उगाया जाता है और कई बार यह खेत में प्राकर्तिक रूप से भी उग जाता है। इस हरी खाद से भूमि की उर्वरा शक्ति बढ़ती है और उत्पादन में भी आशातीत बढ़ोत्तरी होती है।   एजोला की सतह पर नील हरित शैवाल सहजैविक के  रूप में विध्यमान होता है। इस नील हरित शैवाल को  एनाबिना एजोली के  नाम से जाना जाता है जो  कि वातावरण से नत्रजन के  स्थायीकरण के  लिए...
