Agriculture is the science or occupation of cultivating land and rearing crops and livestock. Since food is the most basic necessity for human survival, ‘Agriculture’ is of utmost importance and thus agriculture sector occupies prominent position in the national economy.

The present work, encyclopaedic in nature, contains authoritative description of all vital aspects of Agriculture. Supported by facts and figures, this work will prove beneficial and useful for students, researchers, agricultural scientists and policy planners in the field.

This book is intended to act as a guide to the study of structure of plants. Every student of Botany must have knowledge of the construction of plants and the function of their organs. This book serves their purpose. This is one of the best ever written on fundamentals of modern botany, i.e., structural botany. Throughout the book the author has followed on the whole of descending order, proceeding from the more complex to the more simple, though there have been many exceptions in this rule, because it is impossible to arrange any set of plants in single linear series, whether according to increasing or decreasing complexity.

If any real knowledge of the subject is to be gained, practical work is essential and it is expected that the teacher should have sufficient training to be able to demonstrate to his class most of the structural features described in this book. A plant like all living things is made up of organs, thus a leaf, a stem, a root or a flower is not merely a part of plant but it is a part which does some definite work for the good of the whole. It is hoped that the students of botany and allied science may derive help from this book and it may awaken in some readers a genuine interest in the study of living things.

Plants have direct relationship with human life. In a way, animal life depends on them and vice-versa. Actually, plants release a gas, called Oxygen (O), which is inhaled by animals. In return, animals release carbon dioxide (CO2), which is absorbed by plants. It means, for life existence of each of them, both are necessary.

Besides, plants play other crucial roles in forming a healthy environment. They prove to be very beneficial in lessening the warming of the sun and the effect of air pollution. Moreover, plants also check soil erosion, and thus, help human from the wreckage of floods. Besides, a number of other important issues have been dealt with minutely in the present work. Written in simple, comprehensive language and interesting style, it makes a delightful read.

The Popular Cyclopaedia of Natural Science s intended to serve s a guide to those who are inclined to make the wonders of the vegetable kingdom an object of their regard, either as a source of recreation, or with those higher views to which the student of Natural History can scarcely avoid being led. For although no doubt can be entertained by the reflecting mind, that the power, wisdom, and Goodness of the creator are everywhere operating with equal energy, whether in the simple but majestic arrangement of the heavenly bodies, or in those changes by which our own, globe, is rendered fit for the habitation of such innumerable multitudes of living beings, no one cane help feeling that it is in the structure and actions of these beings themselves, that these attributes are more evidently manifested to the intelligent observer. And although the animal kingdom has usually been regarded as affording more remarkable instances of their display than the vegetable world, it may be doubled whether, when the latter is more closely examined, it will not appear equally or yet more wonderful;-the simplicity of the means being most strikingly contrasted with the vastness of the ends attained.
