This book provides a broad outline of weed management in aerobic rice. In the 21st century along with population pressure, the scarcity of agricultural land, water and shortage of labour maintained pressure for a shift towards aerobic rice cultivation. Aerobic rice is a new way to decrease water requirements in rice production. Aerobic rice suffers more due to weed menace as the weeds. The labour requirement for weeding is a major impediment to the adoption of water saving aerobic rice. Herbicides are considered to be an alternative or supplement to hand weeding, which accelerates the pace of rice production by chemical weed management practices in aerobic rice. The book would prove useful to research scientists for weed management in aerobic rice.

This book covers theoretical methods for the design of continuous time controllers for linear multivariate systems. It is intended for use by those wishing to build on a first course in control systems, either to expand their knowledge as practising engineers or as postgraduate students doing higher degrees in control engineering. Based on material used in graduate courses taught by Professor Balasubramanian at the University of New Brunswick, this book brings together state space and frequency domain design methods for linear multivariable systems. It compares their similarities and highlights the advantages or disadvantages of the various approaches for particular applications. Divided into eleven chapters this book covers in some depth: state space design methods, frequency domain methods for multivariable systems, characteristic locus desiqn methods and stochastic control problems.
