केनोपी की शुक्ष्म जलवायु का अंगूर और वाईन की गुणवत्ता पर प्रभाव Many of the earlier observations among several viticulture scientists all over the world indicated a strong effect of climate on both yield and quality of grapes. To fully understand these effects, we need to differentiate between three levels of the climate based on the ideas of the famous German climatologist, Geiger. Macroclimate (Regional climate): This is the climate of a particular region, and a weather stations located in that region usually describe the general pattern of the macroclimate. Mesoclimate (Site climate): The mesoclimate of a particular vineyard varies from macroclimate of region because of differences in elevation, slope, aspect or distance from moderating...

फसलों की रोपाई की नाली सि‍चि‍त उभरी क्‍यारी प्रणाली और फसल उत्पादन में उभरी क्‍यारी रोपाई के फायदे In bed planting systems, wheat or other crops are planted on the raised beds in ridge - furrow system. This system is often considered more appropriate for growing high value crops that are more sensitive to temporary water logging stress. Farmers often raise crops such as cotton, maize-soybean and wheat on the raised beds. However, the practice of growing rice, the major water-using crop in rice-wheat systems, on narrow raised beds was introduced only very recently in the Indo-Gangetic Plains (IGP) to reduce water use, conserve rainwater and improve system productivity. Recent work shows...

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...

Integrated pest management of cucurbits in dry area कददूवर्गीय सब्जियों को मानव आहार का एक अभिन्न भाग माना जाता है. एक आदमी को रोजाना 300 ग्राम सब्जियां खानी चाहिए परंतु भारत मे इसका 1/9 भाग ही मिल पाता है. भारत दुनिया में सब्जी उत्पादन मे दूसरा सबसे बड़ा देश है और चीन का पहला स्थान है. सब्जियां विटामिन और खनिज लवणों का समृद्ध स्रोत होते हैं. सब्जी उत्पादन में कीडों से बहुत नुकसान होता है. भारत मे कीडों, रोगों, सुत्रकृमियों एवं खरपतवारों से 30% तक नुकसान होता है. कददूवर्गीय सब्जियों में लगने वाले कीट निम्नलिखित है: कददूवर्गीय सब्जियों मुख्य कीट 1. फल मक्खी: वैज्ञानिक नाम: बैक्ट्रोसेरा (डैक्स) कुकुरबिटी, कुल: टैफरीटीडी, गण: डीपटैरा पौषक पौधे: फल मक्खी का आक्रमण सभी कद्दू कुल के...

अरहर या तूर फसल के 6 प्रमुख कीट पतंग और उनके प्रबंधन Pigeon pea (Cajanus cajan L.,) is an important legume crop belonging to the Fabaceae family. In India, it is mostly cultivated during rainy (kharif) season as sole or intercrop for green vegetable and dry seed purpose. Major pigeon pea growing states of our country are Maharashtra, Uttar Pradesh, Madhya Pradesh, Karnataka, Gujarat, Andhra Pradesh, Tamil Nadu and Bihar. Among the various constraints limiting Pigeon pea production, insect pests are the major ones. The important insect’s pests’ causes’ economic loss by attacking the crop at vegetative and reproductive stage are Pod borer, Helicoverpa armigera, Legume pod borer, Maruca testulalis, Pod fly,...

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...
