| The objective of this study was to evaluate the flow of nitrogenous compounds, protein degradability, rumen degradation of total carbohydrate and organic matter and microbial efficiency in heifers subjected to diets containing corn silage, sugarcane or Tifton. For this purpose, the 2,6-diaminopimelic acid (DAPA) technique was adopted and analytical procedures for amino acids by HPLC were adapted. Six rumen-fistulated Holstein-Zebu heifers with 480 kg of initial BW and at 24 months of age kept in individual tie stalls were assigned to two 3 × 3 Latin squares. Omasal digesta dry matter and microbial dry matter flows were determined using the isolated, purified and enriched lignin (LIPE®) and DAPA markers, respectively. Isolated bacteria from rumen showed on... |

| ABSTRACT This article explores decision analysis regarding Drop and Hook (D&H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&H systems. A D&H strategy maximises truck utilisation, as semi-trailers can be handled independently of the traction unit of the trucks, which makes the transport system more agile. For internal D&H systems the semi-trailer detaching/attaching point is located inside the mill site while for external D&H systems it is located outside, before the trucks’ weighbridge. Each configuration requires... |

| A good indicator of successful farm redistribution cases has to be the continuation of viable productivity rates in their post transfer periods. Continued productivity benefits all the stakeholders that are involved in the process. Unfortunately negative productivity levels have been reported in numerous South African land redistribution transfers in recent years. A game theoretic perspective is adopted to argue that cooperation among key stakeholders, which could be enforced through long term contracts between a land buyer, sellers and new owners, would lead to higher productivity levels and other benefits. Additional benefits would, for example, include market related prices paid by a buyer. Sugarcane farm transfer cases from two municipality districts... |

| Nitrogen fertilization is a major component of the cost of agricultural production, due to the high cost and low efficiency of fertilizers. In the case of urea, the low efficiency is mainly due to losses by volatilization, which are more pronounced in cultivation systems in which plant residues are left on the soil. The objective of this work was to compare the influence of urea coated with sulfur or boric acid and copper sulfate with conventional N fertilizers on N volatilization losses in sugar cane harvested after stubble burning. The sources urea, sulfur-coated urea, urea coated with boric acid and copper sulfate, as well as nitrate and ammonium sulfate, were tested at amounts containing N rates of 120 kg ha-1 N. The integration of new technologies in... |

| ABSTRACT Red rot, caused by Colletotrichum falcatum Went is the most important disease of sugarcane in India inflicting substantial loss to both cane industry and cane growers. To keep in view the importance of red rot disease of sugarcane, 117 accession of sugarcane germplasm including different Saccharum species and Indian and foreign commercial hybrids were tested against red rot with Cf 07, Cf 08 & Cf 09 (national pathotypes) by plug method of inoculation. Out of 117, 6 were found resistant and 12 were moderately resistant against red rot and rest were moderately susceptible/susceptible/highly susceptible. Theses resistance and moderately resistant accession can be further utilize to produce resistance varieties against the most devastating... |

| Abstract Hemicellulose and cellulose are essential polysaccharides for plant development and major components of cell wall. They are also an important energy source for the production of ethanol from plant biomass, but their conversion to fermentable sugars is hindered by the complex structure of cell walls. The glucuronic acid substitution of xylan (GUX) enzymes attach glucuronic acid to xylan, a major component of hemicellulose, decreasing the efficiency of enzymes used for ethanol production. Since loss-of-function gux mutants of Arabidopsis thaliana enhance enzyme accessibility and cell wall digestion without adverse phenotypes, GUX genes are potential targets for genetically improving energy crops. However, comprehensive identification of GUX in... |

| ABSTRACT Sugarcane harvester cutting blade wear increases ratoon damages and losses, impairing sugarcane regrowth. This study aimed to evaluate the quality of basal cut using ratoon damage and loss indexes and correlating them with effects on sugarcane regrowth. Harvest parameters such as plant height and position, damage and loss indexes, and stem length were evaluated every 30 min, following statistical process control (SPC) assumptions. Blade wear was examined during three harvesting shifts (0-8 h, 8-16 h, and 16-24 h). Sugarcane regrowth was assessed by counting number of tillers and measuring plant height and stem diameter. The second harvesting shift showed better quality in terms of damage and loss indexes, and plant height and stem diameter.... |

| Se llevó a cabo una caracterización morfológica de 12 variedades de caña de azúcar del estado de Tabasco mediante descriptores morfológicos, se identificó la filogenia por medio de secuenciamiento de la región ITS de DNA ribosómico y trnL-F cloroplástico, y se hizo una caracterización molecular usando la técnica AFLP. La descripción fenotípica se llevó a cabo considerando las características de entrenudo, hoja y yema. En la amplificación del DNA ribosómico se utilizaron los iniciadores ITS4 e ITS5. Para la amplificación del cloroplasto se utilizaron los iniciadores universales trnL-F. El procedimiento para la realización de los AFLPs se realizó siguiendo las recomendaciones descritas en el Kit AFLP®Analysis System I y AFLP® Starter Primer Kit. Entre las 12... |

| The paper has estimated the demand for human labour use in sugarcane and other competing crops and changes over time in its use in major cane-growing states. It has also examined the supply-demand gap in human labour for sugarcane and has provided some coping strategies. The study, based on the primary as well as secondary data on the use of human labour for sugarcane for the past 30 years (1980 to 2010), has found that sugarcane cultivation is least mechanized and most labour-intensive in almost all major canegrowing states of India. The labour-use per hectare has increased in all the cane-growing states, except Tamil Nadu and Maharashtra. Study has revealed that the proportion of casual labour has increased over the years in sub-tropical states because... |
