the efficiency of tubular netting method of cultivation for kappaphycus alvarezii rhodophyta gigartinales on the southeastern brazilian coast
Journal of Applied Phycology, 2015Co-Authors: Renata Perpetuo Reis, Roberta Rodrigues Das Chagas Pereira, Henrique Geromel De GoesAbstract:Kappaphycus alvarezii must be adapted to different environmental conditions when introduced to other countries. In Brazilian commercial cultivations with muddy bottoms and increased seawater movement, the floating rafts system using tubular net Technique was superior to the tie-tie Technique. However, since this result was from only one cultivation cycle, the efficiency of the tubular net Technique in other environments and in different periods of the year was analyzed to verify which K. alvarezii Farming Technique (tubular net or tie-tie) was more efficient with respect to cost, daily growth rate, and carrageenan yield. The results indicated that the efficiency of the tubular net Technique in the Farming of K. alvarezii yielded higher daily growth rates and lower Farming costs as well as retaining more seedlings on the floating raft that is better for the environment preventing invasiveness.

influence of environmental factors and Farming Technique on growth and health of farmed kappaphycus alvarezii cottonii in south west madagascar
Journal of Applied Phycology, 2015Co-Authors: Mebrahtu Ateweberhan, Antoine Rougier, Cicelin RakotomahazoAbstract:A monitoring programme was established in order to support community-based seaweed Farming in south-west Madagascar by providing scientific information on the effects of physico-chemical and health factors influencing the growth of Kappaphycus alvarezii (cottonii). Six aquaculture site configurations were studied. These consisted of high and low flow locations, off-bottom and long-line Farming Techniques and different benthic/substrate types. At each site, a number of growth and health variables were monitored monthly between January 2012 and March 2013 on 30 randomly selected thalli. Variables included thallus-level growth, intensity of epiphyte and disease infection, intensity of fish and sea urchin grazing and cover of pest seaweed and sediment. The following key environmental variables were also monitored at the site level: water temperature, irradiance, salinity, water depth, wave action, pH and oxygen content. Overall average relative growth rate of K. alvarezii in the region was 4.5 ± 0.06 % day−1 and varied by site and season. Generally, growth rate was higher during the winter season (April–August, 5.04 ± 0.31 % day−1) than in the summer (3.90 ± 0.28 % day−1). The long-line Farming Technique provided higher growth (5.46 ± 0.09 % day−1) than the off-bottom Technique (3.99 ± 0.07 % day−1). Thallus-level analysis showed that fish grazing, epiphyte cover, sediment cover and disease had significant negative correlations with growth, and the four variables were positively correlated. Site-level analysis on the effects of physico-chemical and health factors showed that sedimentation, daily maximum of water temperature and variability, and interactions between these factors were the main determinants of growth. Growth was lower at high sedimentation levels and higher values of maximum temperature and temperature variation. Our findings highlight that Farming should focus mainly in the cold season and long-line Technique in order to limit the major ecological constraints encountered and maintain growth and production at sustainable levels.

effect of surface stone cover on sediment and solute transport on the slope of fallow land in the semi arid loess region of northwestern china
Journal of Soils and Sediments, 2010Co-Authors: Tailong Guo, Quanjiu Wang, Jie ZhuangAbstract:Purpose In the semi-arid loess region of northwestern China, use of stone and gravel as mulch has been an indigenous Farming Technique for improving crop production for over 300 years. However, systematic studies on the effects of stone covers on soil and water conservation have been rarely conducted, except for a few investigations and documentations on the stone cover effects on erosion and solute transport in such a highly erodible loess region.

efficient soil microorganisms a new dimension for sustainable agriculture and environmental development
Agriculture Ecosystems & Environment, 2011Co-Authors: Jay Shankar Singh, Vimal Chandra Pandey, D P SinghAbstract:Abstract Sustainable agriculture is vital in today's world as it offers the potential to meet our agricultural needs, something that conventional agriculture fails to do. This type of agriculture uses a special Farming Technique wherein the environmental resources can be fully utilized and at the same time ensuring that no harm was done to it. Thus the Technique is environment friendly and ensures safe and healthy agricultural products. Microbial populations are instrumental to fundamental processes that drive stability and productivity of agro-ecosystems. Several investigations addressed at improving understanding of the diversity, dynamics and importance of soil microbial communities and their beneficial and co-operative roles in agricultural productivity. However, in this review we describe only the contributions of plant growth promoting rhizobacteria (PGPR) and cyanobacteria in safe and sustainable agriculture development.
