जल संरक्षण के लिए प्रौद्योगिकी को अपनाना - ड्रिप सिंचाई प्रणाली पर एक केस स्टडी Irrigation plays an important role in harvesting the desirable level of yield and supplementing the use efficiency of other inputs. Globally, irrigation water is becoming highly scarce due to over exploitation of water bodies for meeting the demand of increasing population. India, despite having the largest area under irrigation in the world, it suffers from severe shortage of water. The coverage of irrigation is about 47 percent of the gross cropped area.  The main reason for low coverage under irrigation is the low water use efficiency of existing conventional method of irrigations like flooding, which is widely practiced in India. Considering the limited water availability in future for irrigation and other uses, different management strategies have to be evaluated for efficient use of available water. In Indian agriculture, drip irrigation system is considered as one of the efficient management strategies for water conservation. Drip irrigation system saves water and fertilizer by supplying water and nutrients near the roots of plants, either at the soil surface (by surface drip irrigation system) or directly in the root zone (by sub-surface drip irrigation system) through a network of pipes, valves, laterals and drippers. An attempt was made to study the adoption level of drip...

ड्रिप सिंचाई प्रणाली के लिए एसिड ट्रीटमेंट Drip irrigation systems are prone to clogging or blockagedue to improper maintenance, There are Several factors that are responsible for the clogging of drip irrigation system, They include Presence of Microorganisms in the system(Bacterial slime, Algal growth). Presence of Large Particles and the suspended particles (Clay and silt) in the water source, which enter and Block the Drip system. Presence of Certain dissolved salts (Carbonates and Bicarbonates, Calcium and Magnesium, iron) where they precipitate and form deposits within the lateral pipes but some times they also lead to the blockage of the emitters. Filtration of the water through the Primary (Sand Filter (open water source) and Screen Filter (Borewell)) and Secondary Filters (Disc Filter (Costly) and Screen Filter (Cheaper)) do not remove the microorganisms and dissolved salts, The microorganisms interact with the sand particles and they lead to the clogging of the drip irrigation system, To rectify the problem of clogging, Acid or chlorine (chemicals) is injected along with the irrigation water, Hence this process is called as chemigation or Chemical treatment. Acid treatment is used for Rectifying the problem caused by the Dissolved or precipitated salts, whereas Chlorine treatment is used for rectifying the problems caused by the microbial growth In the drip system, These Chemicals can be injected by...

Solar Power Drip Irrigation System - Best way to save energy & water भारत एक कृषि प्रधान देश है हमारे देश की 60 प्रतिशत से अधिक आबादी कृषि गतिविधियों से जुडी हुई है। कृषि उत्पादन में निवेश के रूप में ऊर्जा की महत्वपूर्ण आवश्यकता है। सामान्यतया: ग्रामीण क्षेत्रों में कृषि कार्यों में पंप सेट को चलाने के लिए डिजल का उपयोग किया जाता है जो कि आज कल प्रतिदिन महंगा हो रहा है तथा उसके धुंए और ध्वनि से जैविक पर्यावरण पर नकारात्मक प्रभाव पड़ता है । दूसरी ओर हम देंखे तो पायेंगे कि किसान अभी भी सिंचाई कि परम्परागत (बाढ़ सिचाई) विधियों का उपयोग कर रहे है जिससे पानी की  क्षति अधिक व सिंचाई  की दक्षता भी कम रहती है । आज हमारे देश की 22 प्रतिशत उर्जा (Non-Renewable Energy Consumption) एवं 80 प्रतिशत पानी का उपयोग अकेले कृषि क्षेत्र में होता है । हमारे देश में इस ऊर्जा एवं पानी के अपव्यय को रोकने की बहुत ज्यादा आवश्यकता  है । इन दोनों के अपव्यय को रोकने की सबसे अच्छी प्रणाली "सौर ऊर्जा संचालित ड्रिप सिंचाई प्रणाली" है । इस प्रणाली के प्रयोग से हम ऊर्जा के साथ-साथ पानी के अपव्यय  को भी कम कर सकते है । सौर ऊर्जा संचालित ड्रिप सिंचाई दो प्रणालियों, अर्थात सौर ऊर्जा चालित पंप और ड्रिप सिंचाई प्रणाली का...
