Book excerpt: Rice in Deep Water gives a detailed description of the complex agroecosystem and the growth and development of deepwater rice, a fascinating crop grown by subsistence farmers in the deltas and floodplains of Asia and West Africa flooding to depths of 2-3 metres. An account of the various cultural methods and socioeconomic conditions of the farmers is given, current research efforts to increase productivity discussed and research priorities suggested. The book is designed and profusely illustrated so as to emphasize the complexity and dynamic nature of plant and environment, an aspect so often poorly appreciated and misunderstood.

Available in PDF, EPUB and Kindle. Book excerpt: The book ‘Silent Spring’ written by Rachel Carson in 1962, is considered the la- mark in changing the attitude of the scientists and the general public regarding the complete reliance on the synthetic pesticides for controlling the ravages caused by the pests in agriculture crops. For about ve decades, the Integrated Pest Mana- ment (IPM) is the accepted strategy for managing crop pests. IPM was practiced in Canet ̃ e Valley, Peru in 1950s, even before the term IPM was coined. Integrated Pest management: Innovation-Development Process, Volume 1, focuses on the recog- tion of the dysfunctional consequences of the pesticide use in agriculture, through researchanddevelopmentoftheIntegratedPest Managementinnovations. Thebook aims to update the information on the global scenario of IPM with respect to the use of pesticides, its dysfunctional consequences, and the concepts and advan- ments made in IPM systems. This book is intended as a text as well as reference material for use in teaching the advancements made in IPM. The book provides an interdisciplinary perspective of IPM by the forty-three experts from the eld of entomology, plant pathology, plant breeding, plant physiology, biochemistry, and extension education. The introductory chapter (Chapter 1) gives an overview of IPM initiatives in the developed and developing countries from Asia, Africa, Australia, Europe, Latin America and North America. IPM concepts, opportunities and challenges are d- cussed in Chapter 2.

Download or read book Herbage yield and nitrogen content of four green manure legume crops written by R.J. Briones and published by . This book was released on 1982 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field experiment was conducted on a sandy loam rice field in Nambalan, Mayantoc, Tarlac from september 1980 to may 1981 to determine the most suitable green manure crop for lowland rice and evaluate the effects of inoculation on the nitrogen content at 45 and 90 days old of the four legume species. for cowpea and mungbean 45 days correspond to blooming stage and 90 days correspond to maturity. Stylo ans Kudzu were still on their vegetative stage at bith periods. The results show that green manuring significantly increased the yield of paddy rice. Plants that received green manure produced an average grani yield of 3.6 t/ha compared to 1.55 t/ha of plants that did not receive any green manure. The four green manure legume species: Stylo, mungbean, Kudzu and cowpea did not differ significantly on their affects on the agronomic and yield performance of IR 50. Generally, inoculation significicantly increased the herbage yield and nitrogen content of the four legume species greatly increased the growth and yield of rice. Cowpea and mungbean contained greater N at 45 days (2.94 and s.91% N, respectively) than at 90 days old ( 1.88 and 2.24% N, respectively). Kudzu and stylo on the other hand had greater N content at 90 dyas (3.48 and 3.02% N, respectively) than at 45 days old (2.84 and 2.47 N, respectively). On the amount of N added to the soil, all the legume crops contributed more N when turned under at 90 days old than at 45 days because of greater herbage yield at this stage. The amonut of N that each of the four legume crops can add to the soil at 45 days is: Stylo, 46.22 kg N/ha; Cowpea, 59.68 kg N/ha; mungbean, 62.09 kg N/ha; and Kudzu, 57.43 kg N/ha and at 90 days: Stylo, 149.31 kg N/ha; Cowpea, 78.53 kg N/ha; mungban, 97.45 kg N/ha and Kudzu, 141. 07 kg N/ha. Beacause of this finding, the hay of cowpea and mungbean can be turned under after harvesting and can still contribute considerably to the nitrogen supply of the soil.
