Scientific methods of harvesting, threshing , drying and storage of paddy  विश्व में भारत धान उत्पादन मे चीन के बाद दूसरा सबसे बड़ा उत्पादक देश है। देश मे लगभग 50 प्रतिशत से अधिक लोग चावल का उपयोग करते हैं। धान की फसल मे कटाई से लेकर भंडारण तक लगभग 10 प्रतिशत धान की क्षति हो जाती है। कटाई एवं इसके उपरांत धान में होने वाली क्षति को कम करने की सबसे अधि‍क आवश्यकता है। यह पाया गया है कि कटाई, मड़ाई, सुखाना एवं भण्डारण के दौरान क्षति अधिक होती है। इस क्षति से बचने के लिए वैज्ञानिक विधियों का प्रयोग करना जरूरी है। इन्हीं कुछ विधियों का विवरण यहां प्रस्तुत किया गया है। धान की कटाई:- धान...

पशुओं से अधिकतम दुग्धउत्पादन प्राप्त करने के लिए उन्हें प्रर्याप्त मात्रा में पौषिटक चारे की आवश्यकता होती है। इन चारों को पशुपालक या तो स्वयं उगाता हैं या फिर कहीं और से खरीद कर लाता है। चारे को अधिकांशत: हरी अवस्था में पशुओं को खिलाया जाता है तथा इसकी अतिरिक्त मात्रा को सुखाकर भविष्य में प्रयोग करने के लिए भंडारण कर लिया जाता है। ताकि चारे की कमी के समय उसका प्रयोग पशुओं को खिलाने के लिए किया जा सके। इस तरह से भंडारण करने से उसमें पोषक तत्व बहुत कम रह जाते है। इसी चारे का भंडा़रण यदि वैज्ञानिक तरीके से किया जाये तो उसकी पौषिटकता में कोर्इ कमी...

The use of crop products available at the domestic level in food grain storage by traditional practices भारत में अनाज और तिलहन की फसलों में 10 से 20 प्रतिशत तक का नुकसान अनुमानित है (चहल, 2011)। सरकारी रिकार्ड के अनुसार, अकेले साल 2010 में सरकारी गोदामों में 11,700 टन भण्डारित खाद्यान्न सड़ जाने से भारत को भारी आर्थिक नुकसान पहुंचा है (चहल, 2011)। अनाज की खपत की भारी मांग और उसके महत्व को ध्यान में रखते हुए अनाज के उचित भंडारण को नकारा नहीं जा सकता। सुरक्षित भण्डारण के लिये कई पारम्परिक प्रथाएँ आसानी से प्रयोग में लाई जाती है व काफी किफायती और वातावरण के अनुकूल है। ये प्रक्रियाएं आमतौर पर...

स्थानीय सामग्री का उपयोग करके अनाज के सुरक्षित और कि‍फायती भंडारण के लिए स्वदेशी प्रथाऐं।  Keeping in mind the importance and high demand of cereals for consumption, their proper storage must not be neglected. The post-harvest damage caused during storage is mainly due to infestation by storage pest causes huge quality losses in food grains combined with economic losses. This damage may be due to direct feeding of grains by insects and pests or by microbiological agents like fungi and bacteria. The post-harvest losses of food grains and oilseeds are estimated to be 10 to 20 per cent in India (Chahal, 2011).  India experiences severe losses in storage of food grains, as per...

एन्थूरीअम कट पुुुुष्‍पों का कटाई उपरांत प्रबंधन Anthurium (Anthurium andreanum) is an evergreen, tropical, perennial herbaceous plant grown for showy cut flowers valued for colorful, long lasting, cylindrical spadix subtended in large heart shaped spathe and unusually attractive foliage.

However, quality...

गेहूं के विभिन्न अंत उत्पादों के पोषण संबंधी मूल्य पर प्रसंस्करण का प्रभाव To meet the energy need of the ever growing world’s population, wheat is the second most widely gowned cereal after rice in the world. The importance of wheat is mainly due to the fact that its grain can be processed into various end products like flour, semolina, and other bakery products. The quality of these products is directly proportional to preserving the nutrient density of wheat while processing. Table 1, shows the nutritional composition of different end products which is comparable with the whole wheat grains. Processing of wheat grain involves different regulated steps right from the harvesting...

गेहूं अनाज का वैज्ञानिक भंडारण Agricultural commodities have to undergo a series of operations such as harvesting, threshing, winnowing, grading, bagging/packing, transportation and storage before they reach to the consumers. There are significant losses at all these stages.  The most economically important step in case of the cereals like wheat is the storage of the grain produce. Storage is the interim phase in the chain of transporting agricultural products from farmers to consumers. Losses during the storage constitute a significant share of food grain loss in post production operations. With the production of nearly 87 million tonnes of wheat India has potential to meet the food requirement of the country. Losses in wheat...

अंगूर में मूल्य संवर्धन की प्रक्रिया - अंगूर सुखाना Grapes are one of the most popular and palatable fruits in the world. The preservation of grapes by drying is a major industry in many parts of the world where grapes are grown. Drying practices vary with geographical locality and with the variety of grapes.
