Although the green revolution saved millions from hunger but it is also considered responsible for pushing pulses in the corner as far as their research and development is concerned, resulting in the stagnation of production and productivity. Pigeonpea (Cajanus cajan L.) also suffered during this phase and its decade-old productivity stagnation has now become a serious concern. Releasing the first ever commercial pigeonpea hybrid represents a breakthrough towards genetic enhancement of yield. This note briefly discusses the major accomplishments achieved in breeding hybrids and strategies to sustain this momentum in the next decade.To enhance the adoption of these hybrids, it is necessary that quality hybrid seed is produced in large quantities and made available to the farmers at reasonable cost.The hybrid seed technology is profitable and easy to adopt. However, for its sustainability and to understand the production constraints, it was found necessary to validate this technology in famers´ fields under diverse environments.
The present investigation was carried out to study the variability, heritability, genetic advance as per cent of mean, character association, path coefficient analysis and stability analyses among 10 sesamum (Sesamum indicum L.) genotypes in 6 environments resulting from six sowing dates. The data were recorded on 9 quantitative characters (Plant height, days to 50% flowering, number of primaries, number of secondaries, number of capsules per plant, number of seeds per capsule, 1000 seed weight, oil content and seed yield per plant). The analysis of variance indicated significant differences among the genotypes for all characters in all six environments studied.
Mother deer that grieve? Horses that feel shame? Squirrels that adopt their grandchildren? We humans tend to assume that we are the only living things able to experience feelings intensely and consciously. But have you ever wondered what´s going on in an animal´s head? More and more researchers are realising that animals in fact experience a rich emotional life. Acting as our interpreter of the animal world and of the fascinating science, Peter Wohlleben brings this new research to life with his own observations of his favourite creatures. From the leafy forest floor to the inside of a bee hive, The Inner Life of Animals shows us microscopic levels of observation as well as forcing us to confront the big philosophical, ethical and scientific questions. We hear the stories of a grateful humpback whale, of a hedgehog who has nightmares, and of a magpie who commits adultery; we meet bees that plan for the future, pigs who learn their own names and crows that go tobogganing for fun. And at last we find out why wasps exist. Our fellow creatures are not mindless automatons driven by an inflexible genetic code, but individuals with personality and feeling. The Inner Life of Animals will show you these living things in a new light and will open up the animal kingdom like never before.
Working with Dynamic Crop Models: Methods, Tools and Examples for Agriculture and Environment , 3e, is a complete guide to working with dynamic system models, with emphasis on models in agronomy and environmental science. The introductory section presents the foundational information for the book including the basics of system models, simulation, the R programming language, and the statistical notions necessary for working with system models. The most important methods of working with dynamic system models, namely uncertainty and sensitivity analysis, model calibration (frequentist and Bayesian), model evaluation, and data assimilation are all treated in detail, in individual chapters. New chapters cover the use of multi-model ensembles, the creation of metamodels that emulate the more complex dynamic system models, the combination of genetic and environmental information in gene-based crop models, and the use of dynamic system models to aid in sampling. The book emphasizes both understanding and practical implementation of the methods that are covered. Each chapter simply and clearly explains the underlying principles and assumptions of each method that is presented, with numerous examples and illustrations. R code for applying the methods is given throughout. This code is designed so that it can be adapted relatively easily to new problems. An expanded introductory section presents the basics of dynamic system modeling, with numerous examples from multiple fields, plus chapters on numerical simulation, statistics for modelers, and the R language. Covers in detail the basic methods: uncertainty and sensitivity analysis, model calibration (both frequentist and Bayesian), model evaluation, and data assimilation. Every method chapter has numerous examples of applications based on real problems, as well as detailed instructions for applying the methods to new problems using R. Each chapter has multiple exercises for self-testing or for classroom use. An R package with much of the code from the book can be freely downloaded from the CRAN package repository.
The humble soybean is the world´s most grown and most traded oilseed. But it is also a poorly understood crop that is often viewed in extreme terms as a superfood or poison. Christine M. Du Bois reveals its hugely significant role in human history, as she traces the story of soy from its domestication in ancient Asia to the promise and perils it offers in the twenty-first century. This illuminating book travels across the globe and includes a vast cast of fascinating figures who applaud, experiment with or despise soy, from Neolithic villagers, Buddhist missionaries, European colonialists, Japanese soldiers and Nazi strategists, to George Washington Carver, Henry Ford, Monsanto, Greenpeace, landless peasants, petroleum refiners and countless others. The story covers the impact of soy on international conflicts, its role in large-scale meat production and disaster relief, its troubling ecological impacts and the nutritional controversies swirling around soy today. It describes its genetic modification, the scandals and pirates involved in the international trade in soybeans and the use of soy as an intriguing renewable fuel. Featuring compelling historical and contemporary photographs, The Story of Soy reveals the importance of soy throughout history, and why it should never be underestimated.
