Preface
This book provides detailed information about all the aspects of agronomy including
modern concepts and recent advances in agricultural practices to the students who are preparing
for competitive examinations like ARS, IARI, IFS, TNAU ( PG and Ph.D.,) and others in
agriculture and allied fields. Considering the need of the students at large, this book is prepared
to give current aspects in modern agriculture. The different chapters in the book are compiled
after analyzing the information available in various sources such as textbooks, review articles,
popular articles and research articles from different journals .The book highlights the modern
concepts of agronomy like precision agriculture, crop ecology and stress management , organic
farming , agro forestry and social forestry basics objective questions of agronomy like soil and
tillage, weed management and irrigation management, problematic soil management, soil
fertility management, sustainable agriculture and integrated farming system etc.
Recent information and development in the field of agronomy have been incorporated in
the text. Thus this book is based on syllabus of agronomy stream, it may be useful not only to
students but also teachers, researchers and development officer for reference and easy answering
of many complicated questions.
Finally, I have belief and hope that this book will fulfill the requirement of our student of
agronomy stream for appearing in different competitive examinations.

169. Saline soil : The soils having high soluble salt and pH of 8.5 and Ec >4.0 dS/m
170. Saline-alkali soil: The soils having high soluble salts with pH> 8.5 and high
exchangeable sodium
171. Sciophytes : Plants which are shade loving and require less light intensity
172. Seed : Sexually or asexually propagated planting materials which are used seeding or
planting
173. Seepage : It is the lateral movement of water in the soil, water course etc
174. Shifting cultivation : It is the old practice of cutting and clearing of forest for cultivating
crops as long as the soils having fertility
175. Short day plants : Plants which require daylength of < 10hours for flowering
176. Sodic/ alkali soil : Soils having high exchangeable sodium with pH > 8.5
177. Soil conservation : A combination of all land management methods to safegaurd soil
loss against water and wind erosion
178. Soil fertility: It is the status or the inherent capacity of the soil to supply nutrients to
plants in adequate amounts and in suitable proportions
179. Soil productivity: It is the capacity of the soil to produce crops with specific systems of
management and is expressed in terms of yields

180. Solar constant :It is the amount of solar energy received in unit area in unit time usually
at 1.94cal/cm2+/min
181. Solum : is the A and B horizon of the soil profile
182. Sprinkler irrigation : It is the application of water in sprinkle mimics of rainfall as fine
droplets overhead covering entire cropped area.
183. Strip cropping : Growing of two or more crops simultaneously in strips
184. Subsidiary farming : Settled Farming in river banks and streams in addition to gathering
& hunting
185. Subsistence farming : Raising the crops only for family needs and not for commercial :
“Grow it and eat it”
186. Subsoil : The soil present below the plough zone
187. Subsurface irrigation : Application of water in subsoil through trenches, porous pipes
and drip system directly in the rootzone minimizing evaporation losses
188. Suffocation : During winter ice/snow form a thick cover over the ground and the crop
suffers for want of oxygen. Ice in contact with roots inhibits diffusion of CO2 restricting
root respiration.
189. Summer ploughing : The ploughing operations carried out during summer especially in
drylands to absorb rainfall
190. Surface run off : The water flow in excess of the intake of the soil due to high rainfall or
irrigation
191. Sustainable agriculture :Successful management of resources for agriculture to satisfy
the changing human needs while maintaining or enhancing the quality of the environment
and conserving natural resources
192. Systemic pesticide : Chemicals capable of moving within the plants to exert effects
throughout the entire plant system irrespective of its place of entry Ex1.Insecticide :
Monocrotophos and 2.Herbicide : Glyphosate
193. Tillage : Mechanical manipulation of soil with tools and implements to prepare seed beds
conducive for crop production
194. Tilth : Physical condition of the soil resulting from tillage
195. Top dressing : Application of manures and fertilizers after the establishment of plants

196. Transpiration : It is an inevitable loss of water from the plants to the atmosphere in the
form of water vapour
197. Truthful seed : Seeds free of physical purity and good germination
198. VAM (Vesicular Arbuscicular Mychorrizhae) : It is a fungi used to releases unavailable
phosphorus to available form to the plants
199. Vertisol : One of the major soil group of India usually black cotton soil spread the
Deccan Plateau
200. Water requirement : It is the total amount of water required by the crop which includes
irrigation water requirement + effective rainfall + application losses.
201. water use efficiency : It is the amount of drymatter produced from a given quantum of
water and expressed in kg/ha mm
202. White revolution : The accumulated efforts exerted in achieving self sufficiency in milk
production in India
203. Wilting point : It is the soil moisture condition held at 15 atmosphere at which plants
cannot extract water
204. Wind break : Strip of trees or shrubs or crop plants serving to reduce the force of wind
Ex: Casurina along sea coast
205. Yellow revolution :the accumulated efforts exerted in achieving self sufficiency in oil
production in India
206. Zero tillage : The extreme form of tillage where opening the soil, placing seed and
fertilizers and covering the soil is carried out in a single operation
207. Xerophytes : A plant with structural and physiological features that will permit it to grow
in dry habitat. Ex Opuntia
