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...

Earthworm manure, basis of organic farming. आज की सघन खेती के युग में भूमि की उर्वष षक्ति बनाये रखने के लिये प्राकृतिक खादों का प्रयोग बढ़ रहा है। इन प्राकृतिक खादों में गोबर की खाद, कम्पोस्ट, हरी खाद मुख्य हैं। पिछले कुछ सालों से कम्पोस्ट बनाने की एक नई विधि विकसित की गई है जिसमें केंचुआ का प्रयोग किया जाता है, जिसे वर्मी कम्पोस्ट करते हैं। वर्मी कम्पोस्ट, केंचुआ की मदद से निर्मित जैविक खाद है, जिसे किसान भाई स्वयं बना सकते हैं। वर्मी कम्पोस्ट बनाने की विधि :- सर्वप्रथम उपयुक्त स्थान जिसमें उपयुक्त नमी एवं तापमान निर्धारित किये जा सकें, का चयन कर इसके ऊपर एक छप्पर या अस्थाई शेड बनाया जाता है।...

भंडारण बीज के प्रबंधन में स्वदेशी प्रौद्योगिकियां Seeds should have a good storage facility, since seeds are the main input for next crop. Seeds should be stored in such a manner, that its germination capacity and vigour should not decline. The quality of seeds have critical influence on the ability of crops to become established and to realize their full potential of yield and value. Nearly 30% of the seeds are lost during storage period due to insects, rodents and microorganisms. Management of these insect pests by chemical method is not economically feasible but also unsafe for consumption. There is evidence of ash, sand,herbs used in ancient civilization, which have been credited with mystical...

गांय में फि‍रने की समस्‍या - दूध उत्पादन में एक बाधा Fertility is the most essential criterion for the success of the food animal husbandry. Regular and timely conception and calving is very essential for profit oriented dairy keeping. In cattle, especially in cross bred cattle, many farmers’ experience this unwarranted and loss making condition called Repeat Breeding. In this, cows will come to heat regularly but they fail to conceive after successful mating. This repeat breeding will incur expenditure by cost of repeated inseminations, cost of management of this condition, cost of feeding without production, loss of milk due delayed conception. We can call a cow “repeat breeder” only when it should...

6 Major diseases of Aloevera or Gwarpatha and Their Prevention ग्वारपाठा या घृतकुमारी (Aloevera) कांटेदार पत्तियों वाला पौधा हैं, जिसमें रोग निवारण के गुण कूट-कूट कर भरे पड़े हैं। यह भारत के गर्म प्रांतों में पाया जाने वाला एक बारहमासी पौधा हैं  और लिलिएसी परिवार से संबंधितहैं। आयुर्वेद में इसे घृतकुमारी की 'उपाधि' मिली हुई हैं तथा महाराजा का स्थान दिया गया हैं। ग्वारपाठा की 200 जातियां होती हैं, परंतु 5 ही मानव शरीर के लिए उपयोगी हैं। यह खून की कमी को दूर करता हैं तथा शरीर की रोग-प्रतिरोधक क्षमता को बढ़ाता हैं। पत्तियों का रस माइकोबैक्टीरियम क्षयरोग के विकास को रोकता हैं। यह एंटीइन्फ्लामेंटरी, एंटीसेप्टिक, एंटी अलसर ,एंटी टूमओर और...

बायोचर - कृषि का भविष्य The amount of carbon in the soil is a direct indication of good quality of soil. Higher carbon stocks have a direct correlation with increased agricultural yields through improved soil health. In the current scenario of climate change and global warming, much of carbon in atmosphere has to be sequestrated into soil carbon pool so that increasing CO2 in the atmosphere and resulting warming could be reduced. The use of biochar can be a simple yet powerful tool to combat climate change by sequestering much of atmospheric carbon into soil as well as providing an opportunity for the processing of agricultural and other waste into useful clean energy. What is...

ति‍लहनी फसलों में गंधक की कमी  Sulphur is an essential nutrient element for plant as well as animal kingdom. It often accumulates in areas with volcanic activity, and mostly found in organic form in soils. Though S is a secondary nutrient element, its uptake is 9-15% of N uptake and similar to that of P uptake. Crucifers are found to have much more requirement of S than other crops primarily because of oil production and other essential S containing volatile compounds. Sulphur deficiency is wide spread across the world soils (Scherer, 2009). Intensification of agriculture with high yielding varieties and multiple cropping coupled with use of high analysis sulphur free fertilizers along with...
