मिट्टी में पोषक तत्वों की उपलब्धता में वृद्धि के लिए फसल अवशेषाेें का रखरखाव Crop residues have multiple uses on agricultural and allied sectors. Rice-wheat is the founder cropping system of Indo-Gangetic Plains (IGP) of South Asia which support food and energy source of a millions. Burning and/or removal of crop residue are not economical rather than endanger to ecosystem functions. A multiple problems are faced by crop growers on managing residues at time of harvesting to proceed for next crop. However, by adopting some useful interventions, a sizeable quantity of primary plant nutrients can be supplemented in soil without sacrificing the economic return of targeted crop. Crop residues are organic vegetative crop...

समस्याग्रस्त मिट्टी का प्रबंधन कैसे करें For the management of problematic soils,  some general principles has to be considered for proper implementation of the reclamation measures. The total soluble salt concentrations in the root zone have to be decreased to control osmotic effects on plant growth. Maintenance of total soil moisture tension must be ensured at optimum level so that plant roots can absorb an adequate amount of water. Water flows through the soil in the direction of maximum decrease of hydraulic head and the flow velocity is proportional to the hydraulic gradient. The design and layout of drainage system are controlled by this principle. The availability of good quality water is of paramount for...

मृदा पोषण में तरल जैवि‍क खाद की भूमिका Manures are organic materials with plant nutrients in small concentrations. Organic manures are the main source of replenishing soil fertility. Organic farming is an internationally regulated legally enforced and standardized alternative paradigm relies on ecological processes, biodiversity for sustaining the health of soil. Solid organic fertilizer, cattle manure and green manure are the most nutritive organic fertilizers with an average nitrogen (N) content of 1.5%. Now a days Liquid Organic Manure has largely remained in background of bio-dynamic farming. The plant can absorb nutrients about 20 times fast through the leaves than applied through the soil. Therefore, liquid manures are helpful to overcome temporary nutrient shortages. In organic...

धान फसल में नाइट्रोजन उर्वरक प्रबंधन में लीफ कलर चार्ट की भूमिका Paddy is the most staple and nutritive food crop for world human population and other animals.It requires nutrient elements for their establishment and survival. Among those nutrient elements, nitrogen (N) is the most important nutrient which is essential for photosynthesis and thereby increases the yield. Unlike other crops, N can be managed effectively at real time all the stages of crop growth by using Leaf Colour Chart (LCC). Even this technique is being in use for several years, most of the formers are not aware of this technique. But this is simple, inexpensive and easy technique to manage the N in...

सटीक नाइट्रोजन उर्वरक प्रबंधन के लिए आधुनिक उपकरण और तकनीक Food production is commensurate with fertilizer usage. Among the three major fertilizers, nitrogen, phosphate and potassium, application of nitrogenous fertilizers is the maximum. It is reported that China, India and Pakistan together consume approximately 70% of nitrogen fertilizer consumed globally. These figures of nitrogen fertilizer consumption point towards emerging environmental pollution issues. The estimated food production demands would require application of N fertilizer to the tune of 116.0 million tonnes in 2016 and 58% of it would be required in Asia alone of which India’s share would be 30% (FAO Report, 2012). The consumption of N fertilizer in form of urea has increased many...

10 Major physiological disorders of palm and their management खजूर शुष्क और अर्द्ध शुष्क क्षेत्रों की बहुत महत्वपूर्ण बागवानी फसल है, जहाँ का तापमान 50 डिग्री सेल्सियस के ऊपर, पानी और जल की प्रकृति क्षारीय हो, वार्षिक वर्षा 200 मिमी. से कम हो और कोई अन्य व्यवसायिक फसल नहीं होती हो । अतः उन क्षेत्रों के लिए खजूर की फसल एक वरदान है, क्योंकि खजूर की खेती में लागत कम, उत्पादन अधिक और बाजार में मांग भी अधिक होती है। यह फसल इन क्षेत्रों की अर्थव्यवस्था और सामाजिक जीवन में केंद्रीय भूमिका निभाती है।  उत्तरी अफ्रीका और मध्य पूर्व एशिया के शुष्क क्षेत्रों में खजूर के फल एक प्रमुख खाध्य फल है। खजूर की...

कारगिल, लद्दाख क्षेत्र में कोडलि‍गं मोथ के प्रबंधन के लिए एक संभावित उपकरण - सामूहिक फंदा (मास ट्रैप)  Mass trapping is just as the name suggests, placement of a large number of traps in an area, which usually have a sticky cardboard bottom baited with pheromone lures. The lure mimics the scent of a female moth attracting male moths to the trap with the result preventing or delaying mating. Mass trapping requires a high density of traps in order to remove enough males to reduce insect damage. Mass trapping has been attempted for a variety of agricultural, orchard and forest pests on scales ranging from a few to thousands of hectares ....

प्याज की बेहतर किस्मेें Onion (Allium cepa L.) 2n=2x=16, is one of the important bulb crops belonging to family Alliaceae and has gained the importance of a cash crop in recent years because of its very high export potential. The common onion contains 88.6-92.8% moisture, 0.9-1.6% protein, 0.2% fat, 5.2-9.0% carbohydrates, 50-51mg sulphur and 23-28 calories energy per 100 g of edible portion. Onion is characterized by its distinctive flavour and pungency, which is the due to Allylpropyl-disulphide, a sulphur containing compounds found in the scales of the bulb. The red and yellow colour of outer skin of onion is due to presence of Anthocyanin and Quercetin, respectively. Anti-fungal activities in onion is due to...
