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...

स्व-परागण सब्जियों की खेती में प्रजाति‍ संरक्षण और नाभिक बीज का उत्पादन Vegetable breeding programme results in the production of improved cultivars in vegetable crops. At the time of variety release a small quantity of seed is available with the breeder.  The relatively small amount of seed of improved cultivar needs to be multiplied and made available to farmers as quickly as possible. During seed multiplication, varietal purity and identity needs to be maintained. Each multiplication cycle starts from the ‘breeder seed’.  If the breeder seed is not of high purity, the contaminants present get multiplied several times in the succeeding generations of foundation and certified seed production. The presence of contaminants...

वर्मीकंपोस्टिंग अनवरत या सतत खेती के लिए एक पारिस्थितिकी-अनुकूल दृष्टिकोण Vermicomposting is a modified and specialised method of composting - the process uses earthworms to eat and digest farm wastes and turn out high quality compost in two months or less. Vermicompost is not a biofertiliser as is touted by some, merely improved compost.  Vermicompost can also be used to make compost tea. Vermicompost tea is useful as a prophylactic against pests and diseases, for pest repelling and as a foliar spray. A by-product of vermicomposting called vermiwash (which can be collected if there is a tap at the base of the vermicompost tank) also serves the same purpose.An important point to...

अधि‍क कमाई के लिए स्ट्राबेरी की खेती Strawberry (Fragaria x ananassa Duch.) is one of the best natural sources of antioxidant, vitamin 'C', proteins and minerals like P, K, Ca and Fe. It is also anticarcinogenic and anti diabetic. The introduction of day neutral cultivars, fertigation, green house, standardization of agro-techniques and improved storage techniques has revolutionized the strawberry industry. Soil and climate to grow Strawberry Strawberry prefers soil reasonably rich in humus because of 70-90 % of its roots found in the top 15 cm soil. Strawberry should not be grown continuously on the same land and on the land previously devoted to potato, tomato, eggplant, pepper and raspberry. It grows well on...
