Climate change impact and adaptation pathways for forest dependent livelihood systems in Nigeria
Climate change is projected to adversely impact rural livelihoods; especially forest communities dependent on climate sensitive natural resources. Communities within five ecological regions (Mangrove, Rainforest, Guinea savanna, Sudan savanna and Montane forest) in Nigeria were assessed using structured questionnaires to gauge the impact of climate change and adaption responses. Households in the Mangrove, Rainforest,...

Impact of desilting of irrigation tanks on productivity of crop yield and profitability of farm income
Irrigation tanks are one of the major water and common property resources in Southern Peninsular India. Declination of irrigation tanks threatens the agriculture productivity and water availability in the South and Southeast Asia especially in southern Peninsular India and Sri Lanka. The storage capacity of the tank has been decreased due to the factors such as siltation of supply channels, tank bed and irrigation...

Modeling of rapeseed at maturity stage using 3D unorganized point clouds and digital images
Creating 3D plant models is often a difficult and laborious task. To make it easier and more natural, the integration of digital images and 3D unorganized point clouds from a digitizer provides a promising approach for rapeseed model generation. In the present study, 3D unorganized point clouds and digital images were incorporated in the generation of complex models of rapeseeds at maturity stage. Unorganized point...

Nutritive value assessment of three range plants by chemical and in vitro gas production techniques
This study was conducted in order to measure the nutritional value, as ruminant food, of three range plants (Dactylic glomerata, Onobrychis sativa and Setaria galauca), that were collected completely random from north of Iran (Guilan). Chemical analysis and in vitro gas production technique were used as the base for that evaluation. The chemical composition in term of ash, ether extract (EE), crude protein (CP), acid...

Effects in mechanical properties and structure of the soil after tillage with rotary paraplow
At present great emphasis is being put on soil preparation tools which conserve the initial conditions of soil structure, preventing erosion and preserving soil for future generations. A new conservational tillage tool – the rotary paraplow, it were carried out studies addressing the changes in structure and in mechanical properties of soil after tool operation. Dimensional analysis has been used as methodology...

Development of small dams and their impact on livelihoods: Cases from northern Ghana
Small dams offer a lifeline to rural communities in northern Ghana during the dry season. The paper discusses issues related to water use, socio-economic significance, and sustainability of small dams following substantial State interventions and donor agency investments in the development and management of small dams in Ghana. Through the lenses of political economy narrative, the paper explores the political, economic...

Variation of soil properties and phosphorous fractions in three cropping systems of lower indo-Gangetic alluvial plain
The variation of soil properties and phosphorous fractions in three different cropping systems were investigated in Chinchura-Mogra and Polba-Dadpur block of Hugli District, West Bengal representing lower Indo-Gangetic alluvial plain. One perennial cropping system (mango and banana plantation) and two annual cropping systems (Paddy-paddy and paddy-potato) were selected for this study. Sampling points were selected based...

Potentiality of a desert plain soil to irrigation in River Nile State-Sudan
In this research GPS (Garmin-GPSmap276C) was used to locate the observation sites and explore potentiality of soils of the area east of Shendi town, Shendi Province-River Nile, State of Sudan which is about 12751 ha and comprises a flat to slightly undulating desert plain with low gravely ridges and low jebels in south western and north western parts for irrigated agriculture in terms of the suitability of the landscape...

Production of a novel bioformulation of Trichoderma/Hypocrea using biotechnological approaches
Seven different strains of Trichoderma isolated from wilt infected legume fields of UP State were tested for their antagonistic activity against Fusarium (soil borne pathogen), which is expressed as a zone of inhibition in the culture plates. Seven strains were identified as Trichoderma viride, Trichoderma harzianum, Trichoderma asperellum, Trichoderma koningii, Trichoderma atroviride, Trichoderma longibrachiatum and...

Genetic variability in the isolates of Bipolaris maydis causing maydis leaf blight of maize
Thirteen isolates of Biploaris maydis (BM 1- BM13) were collected from different locations of India and their genetic variability was studied using random amplified polymorphic DNA (RAPD), internal transcribed spacer (ITS) and internal transcribed spacer-restriction fragment length polymorphism (ITS-RFLP) techniques. Of the 31 RAPD primers, 21 primers showed polymorphisms in the isolates, but 10 primers failed to...

Effect of weed management methods on weeds and wheat (Triticum aestivum L.) yield
An experiment was conducted at Holetta Agricultural Research Center to study the effect of weed management practices on weeds and yield of wheat (Triticum aestivum L.) during 2010 to 2011 crop seasons in randomized complete block design with three replications. The experiment comprised of twelve weed management practices as treatments. The crop was infested with Avena fatua L. Cynodon dactlylon (L) Pers, Digitaria...
