अनुवांशिक रूप से संशोधित फसलों का पता लगाने के लिए पार्श्व प्रवाह इम्यूनोएसे The development technologies in genetic engineering give rise to genetically modified organisms (GMOs). Genetically modified (GM) crops have become a reality in agriculture, food and feed market. Genetic engineering includes – insect resistance, herbicide tolerance, drought and salt tolerance, improved colors in fiber and flower crops, resistance to water logging and  longer shelf-life. The genetically modified (gm) crops have contributed to the successful incorporation of different traits by introducing transgenes such as bacillus thuringiensis (bt) insecticidal genes (cry1ab, cry1ac, cry1f, cry2ab, cry3a, vip3), herbicide tolerant genes  (cp4epsps, bar, pat, als), virus resistant (cp, prsv-cp, rep, hel), delayed ripening genes (sam-k, acc, pg), genes for color modification. B. thuringiensis and Cry protein toxins are efficient, safe and sustainable...

सतत आय के लिए नारियल की खेती The coconut tree is called as "Kalpavriksha" which essentially means all parts of a coconut tree is useful some way or other. Coconut cultivation is the source of sustainable income especially for small and marginal farmers.  Coconut is essentially a tropical plant but has been found to grow under varying agro climatic conditions. The coconut palm can tolerate wide range of soil conditions. Soil with a minimum depth of 1.2m and fairly good water holding capacity is preferred for coconut cultivation. Preparation of land for Coconut farming:-  Size of the pit depends on the soil type and water table. In laterite soils large pits of the size 1.2m x...

 भारत के आलू उगाने वाले क्षेत्रों में पी उपलब्धता के आधार पर फॉस्फोरस उर्वरकों की सिफारिश Phosphorus is one of the key nutrients required for higher and sustained productivity of potato and its influence on tuber yield is very well established. Maximum potato yield occurs when sufficient P is available during early vegetative development and the entire period of tuber growth. Total plant P uptake increases rapidly during tuber initiation, levels off to a constant rate during tuber bulking, and ceases with plant maturation occurs primarily through the transfer of P reserves from the vine and roots. Phosphorus uptake by potatoes is relatively low compared with uptake of potassium or nitrogen but similar to...

कुफरी गौरव - भारत के उत्तरी-पश्चिमी मैदानी क्षेत्रों के लिए आलू की सर्वाधि‍क नाइट्रोजन दक्ष्‍ा कि‍‍‍‍स्‍म Potato is highly capital and labour intensive crop. Presently, India is the second largest potato producer in the world. For achieving higher productivity, fertilizer inputs particularly of nitrogen are increasing, which not only enhance the cost of production, but also is a major environmental concern.  Therefore, nutrient efficient varieties which produce higher yields per unit of nutrient applied or absorbed than other varieties under similar agro- ecological conditions play an important role in present day agriculture as the nutrient efficient cultivars would enable farmers to produce at a lower fertility level of the soil. Central Potato Research Institute,...

प्रमुख चारा फसलों मे में जीवों के फायदेमंद संघ The main constraints for productivity of fodder crops are lack of availability of soil nutrients, quality seeds and various pests and diseases. These constraints not only influence on the productivity, but also quality of fodder. Resource poor farmers often cultivate forage on low productive soils to make use of the idle land and do not apply the required quantity of nutrients. Such farmers have several options to boost crop yields by applying low cost inputs such as soil amendments, organic manure and bio-fertilisers. Unfortunately, most of them do not bother to apply biofertilisers and soil amendments due to their ignorance and difficulty in procuring...

 दलहनी फसल अरहर में एकीकृत रोग प्रबंधन Pigeon pea is an important pulse crop and has major role in food and nutritional security because it is a rich source of protein, minerals and vitamins. The cultivated area and production of pigeonpea have recorded a steady positive growth in the past 50 years, but the mean national productivity has remained unchanged at around 700 kg/ha. To increase its productivity, breeders are trying to develop suitable varieties with subjective spread, growth, duration, disease and pest resistance under varied agro-climatic growing conditions.  Diseases are a continual problem and control measures must be planned for developing sustained production. Each condition that affects plant growth also affects the disease...

जलकुंभी: कृषि के लिए एक गंभीर खतरा Water hyacinth (Eichhornia crassipes) is a free floating perennial aquatic plant, native to South America.  Water hyacinth is a popular water garden plant because of the beauty of its large, purple to violet flowers and its interesting floating vegetation. Many plant nurseries and big box stores sell it as an ornamental pond plant. Later it was seen that the plant is basically a very aggressive invader which can form thick mats on water surface. Gradually, it is known that among the aquatic plants, water hyacinth is the worst aquatic plant in the world. It becomes a fierce competition with other micro flora and fauna in the...

दार्जिलिंग हिमालय क्षेत्र में कृष्‍णा फलों का विश्लेषण Passion fruit (कृष्‍णा फल), a high value foreign exchange earning fruit crop rich in appreciable quantities of vitamin A, B, C with medicinal value, is mostly grown at an altitude of 800-1500 m above mean sea level. The cultivation of passion fruit is mostly restricted to few of the North Eastern states and hilly regions of South India. It has a very good scope of commercial cultivation in the Darjeeling Himalayan Regions of West Bengal particularly Kalimpong and Kurseong subdivisions. This will help the small farmers to improve their economic condition that ultimately leads to overall prosperity of this region.  Darjeeling Krishi Vigyan Kendra will provide...

मक्का में जस्ता की कमी और निगमन Zinc is a micro-nutrient essential for the growth and development of plants, animals and humans. Zinc has several important functions in plants, including major roles in enzyme reactions, photosynthesis, DNA transcription and auxin activity. Of all micro-nutrients, zinc is the most often deficient in corn production and most likely to elicit a yield response when applied as fertilizer. However, yield responses are only attainable when zinc is deficient and therefore limiting yield.  Role of Zinc in corn plant Synthesis (production) of growth hormones and proteins. Production of chlorophyll and carbohydrate metabolism. Essential for the transportation of calcium throughout the corn plant.  Cell elongation, the increase in leaf and node size...
