Soil & Fertilizers

Importance of Seed treatment in Agriculture कृषि क्षेत्र की प्राथमिकता उत्पादकता को बनाये रखने तथा बढ़ाने मे बीज का महत्वपूर्ण स्थान है। उत्पादकता बढ़ाने के लिए उत्तम बीज का होना अनिवार्य है। उत्तम बीजों के चुनाव के बाद उनका उचित बीजोपचार भी जरूरी है क्यों कि बहुत से रोग बीजो से फैलते है। अतः रोग जनको, कीटों एवं असामान्य परिस्थितियों से बीज को बचाने के लिए बीजोपचार एक महत्वपूर्ण उपाय है। बीजोपचार के लाभ अनुसंधान द्वारा पाया गया कि बीजोपचार के लाभ उत्तम पौधों, अच्छी गुणवत्ता, ऊँची पैदावार और रोगों तथा कीट नियंत्रण मे लगी पूंजी पर अच्छी आय के रूप में दिखाई देते है। परंतु आज भी ऐसे किसानों की संख्या बहुत अधिक है,...

मृदा की अम्‍लता भारत में फसलोंत्‍पादन सीमि‍त करने का एक बडा कारक है। Soil reaction is a very important chemical property of the soil. It is measured in terms of pH. The soils having pH 7 are neutral in reaction and those below or above 7 are acidic or alkaline respectively. In neutral soils, satisfactory plant growth can be expected, provided all other agronomic practices are followed properly. But neither acid soils nor saline soils are suitable for most of the crops except a few tolerant ones. Acidity or salinity acts as a limiting factor in crop production. When the concentration of some elements which are naturally acidic in reaction, goes too high...

पोषक तत्व उपयोग दक्षता और फसल उत्पादन बढ़ाने के लिए वनस्‍पति‍क उर्वरीकरण Foliar fertilizationis a technique of feeding plants by applying liquid fertilizer directly to their leaves. Foliar feeding has been used as a means of giving supplemental doses of major and minor nutrients, plant hormones, stimulants and other beneficial substances. Observed effects of foliar fertilization included yield increases, resistance to diseases and insect/pests, improved drought tolerance and enhanced crop quality. Plant response is dependent on species, fertilizer form, concentration and frequency of application as well as the stage of plant growth. Foliar applications are often time to coincide with specific vegetative or fruiting stages of growth. The soil application of any fertilizer...

सब्जी उत्पादन में एकीकृत पोषक प्रबंधन Integrated nutrient management (INM) is an approach to soil fertility management that combines organic and mineral methods of soil fertilization with physical and biological measures for soil and water conservation. INM adopts a holistic view of plant nutrient management by considering the totality of the farm resources that can be used as plant nutrients. Integrated nutrient management is based on three fundamental principles: maximize the use of organic material ensure access to inorganic fertilizer and improve the efficiency of its use minimize losses of plant nutrients Research gaps in integrated nutrient management The research gaps include: Mismatching of INM practices developed at research stations with the farmers resources and their...

Importance of Soil test in Soil fertility भूमि की उर्वरता किसी भी राष्ट्र के लिए बहुत महत्व रखती है किसी भी देश की सभ्यता का अंदाजा वहां के भूमि के सदुपयोग या दुरूपयोग से लगाया जा सकता है। हमारी जनसंख्या दिन पर दिन बढती है। जबकि हमारी कृषि योग्य भूमि सिकुडती जा रही है। हमारे पास ऐसा कोर्इ साधन नहीं है। जिससे कि हम भूमि का क्षैतिज विस्तार कर सके अब यह हमारे ऊपर निर्भर करता है। कि हम इनका उपयोग किस प्रकार करे क्योंकि ये हम सभी जानते है। कि सभी वनस्पतियों तथा प्राणियों का जीवन इसी पर टिका हुआ है। आज के युग में जब कृषि भी एक व्यापार...

मृदा मे सूक्ष्म पोषक तत्‍‍‍‍‍‍‍वाें की वर्तमान स्थिति और फसलों पर उनके लक्षण Micro nutrients are essential for the normal growth of plants. Deficiencies of micro-nutrient drastically affect the growth, metabolism and reproductive phase in plants, animal and human beings. Wide spread deficiencies of micronutrients has been found in Indian soils. About 3 billion people in the world are affected with micronutrient malnutrition. Crop plants requires 17 nutrient elements viz. C, H, O, N, P, K, Ca, Mg, S, Fe, Cu, Mn, Zn, B, Mo, Cl and Ni for completing their life cycle. Out of these last eight elements are micro nutrients that are needed in very less amount for crops...

वर्मीकंपोस्ट - उत्पादन और क्रि‍याऐं। Vermicomposting is a method of preparing enriched compost with the use of earthworms. It is one of the easiest methods to recycle agricultural wastes and to produce quality compost. Earthworms consume biomass and excrete it in digested form called worm casts. Worm casts are popularly called as Black gold. The casts are rich in nutrients, growth promoting substances, beneficial soil micro flora and having properties of inhibiting pathogenic microbes. Vermicompost is stable, fine granular organic manure, which enriches soil quality by improving its physiochemical and biological properties. It is highly useful in raising seedlings and for crop production. Vermicompost is becoming popular as a major component...

मिट्टी में उर्वरकों का प्रबंधन The fertilizers are becoming costly input day by day. Hence it is felt necessary to study the efficient use of this input. So some important points are given here to increase fertilizer use efficiency and to get higher yield. 1. Management of Nitrogen fertilizers in soil Nitrogen is lost from fertilizers by ways as follows: Volatilization Ammonia volatilization is an economic loss to the farmer in terms of both drained fertilizer prices and decreased crop yields. Some important facts are as follows: The ammonia volatilizing capacities of the fertilizers are graded as urea > ammonium sulphate > ammonium chloride > ammonium nitrate. The ammonia volatilizing capacities of the soils are graded as...

नाइट्रोजन उर्वरकों के सुरक्षित और लाभदायक उपयोग के लिए सर्वश्रेष्ठ प्रबंधन पद्धतियां Indian agriculture has witnessed a tremendous fourfold increase in food production over the past three decades. This enhanced food grain production later known as ‘green revolution’ could be mainly attributed to the introduction of high-yielding, input responsive cultivars of wheat and rice in the mid-1960s and to the increased availability and use of chemical fertilisers, especially the nitrogenous (N) fertilizers. Nitrogenous fertilizers supply N which is very essential for plant growth and development and mainly supplied to the crop plants in the form of urea, Diammonium phosphate (DAP) etc. When N fertilizers are used correctly they are very beneficial, but...

नाइट्रोजन उर्वरकों के अधिक उपयोग के कारण भूजल प्रदूषण After independence our nation's primary aim was to achieve self-sufficiency in the food production. To achieve this aim we incorporated the primary means of maximizing the yields of agricultural crops through use of fertilizers, pesticides and other chemicals besides improving the inherent quality of the seeds. Though it helped our nation in producing the food for ever-increasing population but the unsustainable path used to maximize the yield caused some grave concerns like that of groundwater pollution. Nearly five decades after the Green Revolution the sustainability of Indian agriculture, and thereby the country's food security, are both facing a serious challenge. Water is vital...
