| The exploitation or tapping of the rubber tree, Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg. is one of the most important cultural practices in determining useful life, yield and accounts for a major part of the total production costs in rubber farming. The objective of this work was to evaluate yield performance and economic aspects of rubber tree clones submitted to diverse tapping systems. The trial was placed in Guararapes city, São Paulo State, Brazil, in a randomized block design with split-plot in time. The plots consisted of the IAN 873, PR 261, RRI M 600 and RRI M 701 clones. The tapping systems consisted the subplots, where: ½S = tapping of half spiral cut; d/2, d/3, d/4, d/5 and d/7 = tapping every 2, 3, 4, 5 and 7 days,... |

| ABSTRACT This study evaluates the potential of rubber tree clones (Hevea spp.) under four tapping systems for the Northwestern region of the State of Paraná with the objective of enhance genetic diversification and increase natural rubber production in this new and promising region for rubber tree cultivation by selecting the better combination of clone and tapping system. The experiment was installed at Guanabara Farm, municipality of Paranapoema, Paraná State, in a split-plot randomized complete blocks experimental design with three replications. In the plots 12 clones were tested, namely RRIM 600 (control), IRCA 18, IRCA 111, IRCA 130, PB 235, PB 252, PB 260, PB 330, IAC 15, IAC 35, IAC 41 and RO 38. The subplot treatments consisted of four tapping... |

| Fatigue properties of filled natural rubber in seawater environment are investigated by uniaxial fatigue and crack propagation experiments, and the damage is analyzed by scanning electron microscopy. The behavior under relaxing and non-relaxing loading conditions is studied and the results are compared to those obtained in air environment. For relaxing loading conditions, fatigue behavior is the same in both environments. Under non-relaxing conditions at large strain levels, for which the influence of strain-induced crystallization is important, fatigue life is longer in seawater. Such behavior could be explained by increased internal temperatures of specimens tested in air due to lower heat conductivity of air as compared to seawater. Such conclusion is... |

| Among the various promotional schemes targeted for the promotion of rubber in Tripura, Block Plantation Scheme (BPS) has been introduced exclusively for the rehabilitation of scheduled tribes and scheduled castes. BPS is a comprehensive scheme with the characteristic features of group/community approach in all spheres of operations up to primary processing and marketing and family labour participation as wage labour during the immature phase of the plantations spanning six years. However, there has been a distortion in the uninterrupted supply of family labour to the scheme in the recent past due to growing popularity of employment opportunities under the Mahatma Gandhi National Rural Employment Guarantee Act, 2005 (MGNREGA) programme, which may eventually... |

| Currently, there are great interests in rubber tree planting by farmer in the Northeastern Thailand and the neighboring countries, due to its high return. As a result, there is a question of what are the differences of the rubber production behavioral aspect between the smallholder in the Northeast Thailand and the neighboring countries. Nakhon Phanom province, Thailand and Khammouane province, Lao PDR were chosen as study site. Secondary data, individual and group interviews, and field surveys were used as data collection in during 2010. It was illustrated that both locals had both similar and different production behavior by smallholder. Agronomic practices in term of weeding, fertilizing application, tapping system, and processing of rubber latex are... |
