Different sensors (Soil Moisture, Light, Temperature, level, rain, flow ) with different another device |(water pump, Battery, LCD, Solenoid valve ) have been used to make this project. Drip Irrigation Seminar and PPT with pdf report: Irrigation is the operation of providing water to the land by artificial means for the intention of cultivation.Normally the land gets the water through the natural source like rain but the amount of water that the land gets through rain is insufficient for the plants to grow. Gravity irrigation methods are less expensive, but requires more skill and experience to achieve re-scannable efficiency. 3- Possibility of vegetation growth in banks, leading to increased friction. Irrigation Methods Irrigation water may be applied to crops by flooding the field surface, by applying it beneath the soil surface, by spraying it under pressure or by applying it drop by drops. Irrigation–Principles and Practices Introduction 205 Lecture 1: Irrigation Concepts and Terminology 207 Lecture 2: Irrigation Scheduling and Delivery Systems 209 Demonstration 1: Field-Scale Irrigation 217 Demonstration 2: Garden-Scale Irrigation 219 Hands-On Exercises 1–6 221 Assessment Questions and Key 227 Resources 229 Supplements 1. 1. Here, a farmer pulls out water from wells or canals by himself or using cattle and carries to farming fields. Irrigation Methods John T. Phelan and Wayne D. Criddle There are three general methods of applying irrigation water to the land. The four methods of irrigation: Surface Sprinkler Drip/trickle Subsurface. Irrigation, the addition of water to lands via artificial means, is essential to profit-able crop production in arid climates. Set alert. Also, the chances of water loss are very high. 90% of world’s total irrigated area is under this method. The checkbook method of scheduling enables irrigation farm managers to monitor a field's daily soil water balance (in terms of inches of soil water deficit), which can be used to plan the next irrigation. Irrigation types.pdf. Previously I had told you the meaning of irrigation but here i am going to explain to you about methods of irrigation. Irrigation is also practiced in humid and sub-humid climates to protect crops during periods of drought. This method of irrigation is widely used for row crops, and small furrows, called corrugations, have been used for forage crops such as alfalfa. METHODS OF WATER SUPPLY AND IRRIGATION FOR FARMERS - OPERATED SCHEMES 1986 . But its efficiency is poor because of the uneven distribution of water. The rate of coverage (advance) is dependent almost entirely on the differences between the discharge onto the field and the accumulating infiltration into the soil. This method can vary in different regions. In surface irrigation the soil is the reservoir from which the plants draw the water they need. Module 3 Irrigation Engineering Principles Version 2 CE IIT, Kharagpur Lesson 4 Types of Irrigation Schemes and Methods of Field Water Application Version 2 CE IIT, Kharagpur Instructional objectives On completion of this lesson, the students come to know of the following: 1. Gravity irrigation method. •Role of Irrigation Ollas as a Sub-Surface Irrigation Method •Sub-Surface Irrigation Planters •Using 4 gal. While this is a lesser issue for surface irrigation compared to other irrigation methods (due to the comparatively high leaching fraction), lack of subsurface drainage may restrict the leaching of salts from the soil. METHODS AND DEPTHOF IRRIGATION WATER INTRODUCTION Faulty method of irrigation leads to more wastage of costly irrigation water. Application of larger quantities ofirrigation water in excess ofthe soilmoisture deficit ofthe field also adds to the wastage. Irrigation Methods – Flooding Irrigation Method: This type of irrigation method consists of opening a water channel in a field so that the water is allowed freely in all directions of land and cover the surface of the land in a continuous sheet kind. Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall. The following figures show the schematic description of surface irrigation methods. There are different ways of application of irrigation water to the farm land known as irrigation methods, which ultimately define the magnitude of field losses and thus the field application efficiency. This method is most suitable for low to moderate infiltration rates and leveled lands and having <2-3% slope. Drip irrigation, essential for producing many specialty crops, is used throughout the state on farms of all sizes. This is commonly done with 1/2"-2" diameter pipe placed vertically in the soil 12"-18" deep near the seedling or tree.

Oldest (4000 years back) and most common method. Includes furrow, boarder, basin, wild- flooding and corrugation.
