Effect of Water and Fertilizer Regulation on the Soil Available P Content in Winter Wheat at West Lake Plain and Baiyang Lake in China

Jinbo Zhao, Ming Chen, Jiawei Li, Jinghua Zhou
Water and nutrients are the basic requirements for crop growth, which are mutually interacting and restricted. This paper studied winter wheat (wheat breed: Ji wheat 22) on changes in soil nutrient leaching in the regulation measures of water and fertilizer (two irrigation methods: traditional irrigation (A) and water-saving irrigation (B); three fertilization factors: no fertilization (CK), traditional fertilization (FC) and optimized fertilization (FO)). The results showed that under the diffe...

Agroclimatic Conditions for Growing Sorghum bicolor L. Moench, under Irrigation Conditions in Mexico

Genovevo Ramírez-Jaramillo, Mónica Guadalupe Lozano-Contreras, Jorge H. Ramírez-Silva
Faced with the possible depletion of fossil fuels and the growing demand for energy; the liquid biofuels are being considered as a renewable energy alternative with low impact on carbon emissions. Sweet sorghum (Sorghum bicolor (L) Moench) is a good alternative as it has several advantages in relation to other plant species. Given the interest of the Mexican Government to promote biofuels and S. bicolor in particular, this work aimed to spatially delimit the optimal and suboptimal areas to produ...

Lettuce (Lactuca sativa L.) Production in Republic of Congo Using Hydroponic System

Romeo Ekoungoulou, Espoire Brice Rahmat Mouendo Mikouendanandi
Hydroponic is a subset of hydroculture, which is a method of growing plants without soil by instead using mineral nutrient solutions in a water solvent. The study aimed to assess the behavior of Minetto and Blonde de Paris varieties of Lettuce (Lactuca sativa L.) in hydroculture. The experiments tanks have been installed in Talanga? Micro-garden site, located in Kimbanguiste Church at Brazzaville. The lettuce seeds were sown in a nursery tank, and then transplanted into 4 hydroponic production t...

Production and Characterisation of Briquettes from Carbonised Cocoa Pod Husk and Sawdust

Prince Ofori, Osei Akoto
The demand for wood fuels in rural and some urban areas of Ghana keeps on increasing which could lead to forest degradation. The present study sought to produce and characterise briquette made from cocoa pod husk and a mixed sample which comprised of a mixture of cocoa pod husk and sawdust as an alternative source of fuel to reduce the pressure on wood fuels. Simple methods were used to produce the briquette for the study. The physico-chemical properties of the

Design and Performance Evaluation of a Variable-Feed Hydrous-Bioethanol Fuel Injector for Retrofitted Engine

Alexis T. Belonio, Manuel Jose C. Regalado, Marvelin L. Rafael, Katherine C. Villota, Phoebe R. Castillo
A variable-feed hydrous-bioethanol fuel injector (VFHBFI) for retrofitted en-gine was designed and evaluated to provide a technology that would allow spark-ignition engines commonly used by farmers be fuelled with hydrous bio-ethanol from nipa. With this technology, farmers can make use of their farm resources to fuel their engines making them less dependent on imported fossil fuel. The VFHBFI consists o

Development of an Appropriate Rice-Based Biomass Gasifier as Source of Power for Farm Use

Alexis T. Belonio, Manuel Jose C. Regalado, Phoebe R. Castillo
An appropriate rice-based (ARB) biomass gasifier was designed and de-veloped for farmers’ use. The gasification properties of rice-based biomass were determined before doing the design. The gasifier was built using salvage petrol drums, metal bars and concrete as primary construction materials. It has a 30 cm-diameter reactor insulated with refractory cement. A 10 cm-o cross flow scrubber with 30 cm-thick packed-bed filter is used
