Book Description
This book is the outcome of contributions by many experts in the field from different disciplines, various backgrounds, and diverse expertise. This book provides information on biomass volume calculation methods and biomass valorization for energy production. The chapters presented in this book include original research and review articles. I hope the research presented in this book will help to advance the use of biomass for bioenergy production and valorization. The key features of the book are: Providing information on biomass volume estimation using direct, nondestructive and remote sensing methods Biomass valorization for energy using thermochemical (gasification and pyrolysis) and biochemical (fermentation) conversion processes.

Book Description
Three grain sorghum cultivars were grown in the open field and under seven - and towo-year old rubber trees at there levels of nitrogen fertilizer and plant population density, to determine their performance in both seed and atoon crops in terms of grain yeild and other agronomic characters, quality perameters like protein and total starch content of grains and their effects on stem girth and latex yield of rubber. Comparing the six cultural environments with respect to the parameters evaluated, those grown in the open field and under two-year old rubber trees nanmely, MIT open field seed crop. MIT-open field ratoon crop, Kidapawan-under rubber seed crop and Kidapawan-under rubber ratton crop reduced the number of days to blooming, and gave higher grain and total dry matter yields, 100-grain weight and number of grains per panicle. The same treatments gave higher starch but lower protein content in the grains compared to those grown under seven-year old rubber trees namely. MIT-under rubber seed crop and MIT-under rubber ratoon crop. The u=yield component that was consistently associated with grain yield was number of grains per panicle. Nitrogen treatments increased grain yield, total dry matter yield, plant height, leaf area index and number of grains per panicle. Plant population density reduced leaf size and panicle length in both seed and ratoon crops in all environments. The cultivars showed a wide diversity of performance in different culturtal envivornments. There were as inverse relationships (...).

Book Description
Grain sorghum [Sorghum bicolor (L.) Moench] is an important dryland crop in the Texas Panhandle. Productivity of grain sorghum depends on climatic conditions, plant available soil water, and soil fertility. Previous research has shown growing grain sorghum in clumps instead of Equal Spaced Planting (ESP) reduced plant stress, reduced production of tillers, and increased harvest index and grain yield under dryland conditions. The current study was conducted in the greenhouse and field to investigate the effect of fertilizer application on sorghum plants grown in clump and ESP geometries. The objectives of the research were to (a) compare fertilizer (nitrogen and phosphorus) uptake in grain sorghum plants in clumps and ESP geometries (b) observe root growth patterns in clump and ESP plants (c) and determine the fertilizer effect on tiller formation and harvest index. The greenhouse experiment was conducted at West Texas A&M University during 2014 and 2015. Grain sorghum was grown in clump and ESP geometries with two and three fertilizer levels in 2014 and 2015, respectively. Plants were grown in wooden boxes, with a transparent side, covered by a removable wooden board, so that root growth could be observed. All experiments were conducted in a Randomized complete block design (RCBD) and fertilizer was applied in a band beneath clump and ESP plants. The field experiment was conducted at the USDA Conservation and Production Research Laboratory at Bushland, Texas, during 2014 and 2015. Grain sorghum was grown in clump and ESP planting geometries in unfertilized and fertilized (68 kg N ha-1 and 10 kg P ha-1) plots. Planting density in both geometries was 62,000 plants ha-1. In 2015 corn was grown in clump and ESP planting geometries without using fertilizer. N and P concentrations in grain and stover were obtained from laboratory analysis and data are reported as N uptake in aboveground biomass and P uptake in aboveground biomass In the 2014 greenhouse study, ESP plants had significantly higher N uptake in aboveground biomass, stover yield, and tillers per plant. However, harvest index was higher in clumps. The interaction between planting geometry and fertilizer showed a significantly higher N uptake in ESP with high fertilizer level. In 2015, clump plants had significantly higher grain yield, aboveground N uptake, nitrogen use efficiency (NUE) and phosphorus use efficiency (PUE). Increasing fertilizer level increased P uptake in aboveground biomass. Plants in ESP produced deeper and well developed root systems while clump plants produced roots that developed angularly and then downward. In the 2014 field study, clump plants had lower N and P uptake in aboveground biomass than ESP, but had higher NUE and PUE. Though clump plants had significantly fewer tillers per plant than ESPs, harvest index was not different. In the 2015 field study, planting geometry did not have a significant effect on N and P uptake in aboveground biomass, NUE or PUE. However, the interaction between planting geometry and fertilizer level showed higher N uptake in clump fertilized plants. Clump plants produced fewer tillers per plant. Harvest index was significantly higher in clumps. Fertilized plots had significantly higher N uptake in aboveground biomass but fertilizer had no effect on P uptake. Overall, data suggest N and P uptake in aboveground biomass varies by soil nutrient condition, and level of fertilizer. Increasing fertilizer level increases tiller production in the plants. Application of fertilizer has shown mixed results on N uptake and grain yield in clump and ESP plants. Further investigation is necessary to draw a conclusion on aboveground N and P uptake in plants grown in clump and ESP planting geometries at different fertilizer rates and placement methods.
