Impact of floriculture development enhances livelihood of India’s rural women
(Kassel University Press, 2012)
India’s rural women are involved in various types of work and contribute considerably to the economy. However much of their work is not systematically accounted in the official statistics. India’s governmental and non-governmental data collection agencies admit that there is an under-estimation of tribal women’s contribution as rural workers. This study describes in detail a research project that focuses on the indicators for socioeconomic development in the least developed rural villages by examining the impact of ...

Evaluating partial root-zone irrigation and mulching in okra (Abelmoschus esculentus L.) under a sub-humid tropical climate
(Kassel University Press, 2011)
The field experiments were conducted to compare the alternate partial root-zone irrigation (APRI) with and without black plastic mulch (BPM) with full root-zone irrigation (FRI) in furrow-irrigated okra (Abelmoschus esculentus L. Moench) at Bhubaneswar, India. APRI means that one of the two neighbouring furrows was alternately irrigated during consecutive watering. FRI was the conventional method where every furrow was irrigated during each watering. The used irrigation levels were 25% available soil moisture depletion ...

Comparison of different methods in estimating potential evapotranspiration at Muda Irrigation Scheme of Malaysia
(Kassel University Press, 2012)
Evapotranspiration (ET) is a complex process in the hydrological cycle that influences the quantity of runoff and thus the irrigation water requirements. Numerous methods have been developed to estimate potential evapotranspiration (PET). Unfortunately, most of the reliable PET methods are parameter rich models and therefore, not feasible for application in data scarce regions. On the other hand, accuracy and reliability of simple PET models vary widely according to regional climate conditions. The objective of the ...

Yield gap analysis and assessment of climate-induced yield trends of irrigated rice in selected provinces of the Philippines
(Kassel University Press, 2012)
This study describes a combined empirical/modeling approach to assess the possible impact of climate variability on rice production in the Philippines. We collated climate data of the last two decades (1985-2002) as well as yield statistics of six provinces of the Philippines, selected along a North-South gradient. Data from the climate information system of NASA were used as input parameters of the model ORYZA2000 to determine potential yields and, in the next steps, the yield gaps defined as the difference between ...

Determination of the silvo-melliferous regions of Benin: a nationwide categorisation of the land based on melliferous plants suitable for timber production
(Kassel University Press, 2015-10-07)
Perennial plants are the main pollen and nectar sources for bees in the tropical areas where most of the annual flora are burned in dry seasons. Therefore perennial plants constitute the most reliable bio materials for determining and evaluating the beekeeping regions of the Republic of Benin. A silvo-melliferous region (S-MR) is a geographical area characterised by a particular set of homogenous melliferous plants that can produce timber. Using both the prevailing climatic and the agro-ecological conditions six S-MRs ...

Factors influencing the use of selected inputs in yam production in Nigeria and Ghana
(Kassel University Press, 2015-09-21)
In West Africa, yam can be an important crop to reduce poverty and hunger if Research and Development measures identify and properly engage its key production factors for enhanced outputs and better income. Data from 1400 households in Ghana and Nigeria were collected in a multistage random sampling survey (and complementary data from 76 farm family fields) with a structured questionnaire and qualitative interview questions. The results showed that yam is produced mainly with crude inputs/technologies to reduce high ...

How do consumers perceive organic food from different geographic origins? Evidence from Hong Kong and Shanghai
(Kassel University Press, 2015-05-21)
The objective of this paper is to understand how Chinese consumers perceive certified organic food, especially the differences between locally and nationally produced organic food compared to food produced overseas. In 2012, a consumer survey was conducted at supermarkets in Hong Kong and Shanghai (N=245). Participants were asked for their perception on four different food origins: locally produced organic food, organic food from China, imported organic food, and locally produced conventional food. Consumers in Hong ...

The Koundoum sheep breed in Niger: morpho-biometric study and description of the production system
(Kassel University Press, 2015-05-21)
The diffusion of highly productive breeds across developing countries goes along with a neglect of indigenous breeds, which are well suited to their environment but often show low yields. Thus, in Niger, the flock of Koundoum sheep are rapidly decreasing. The Koundoum is one of the few wool sheep breeds of Africa and shows important adaptive feature to its native environment, i.e. the humid pastures on the banks of the Niger River. To characterise the breed and to understand its production context, a survey has been ...

Evaluation of major feed resources in crop-livestock mixed farming systems, southern Ethiopia: Indigenous knowledge versus laboratory analysis results
(Kassel University Press, 2015-10-08)
Evaluation of major feed resources was conducted in four crop-livestock mixed farming systems of central southern Ethiopia, with 90 farmers, selected using multi-stage purposive and random sampling methods. Discussions were held with focused groups and key informants for vernacular name identification of feed, followed by feed sampling to analyse chemical composition (CP, ADF and NDF), in-vitro dry matter digestibility (IVDMD), and correlate with indigenous technical knowledge (ITK). Native pastures, crop residues ...

Technical and scale efficiency of cassava production system in Delta State, Nigeria: an application of Two-Stage DEA approach
(Kassel University Press, 2015-05-21)
The present study examines the level of pure technical and scale efficiencies of cassava production system including its sub-processes (that is production and processing stages) of 278 cassava farmers/processors from three regions of Delta State, Nigeria by applying Two-Stage Data Envelopment Analysis (DEA) approach. Results reveal that pure technical efficiency (PTE) is significantly lower at the production stage 0.41 vs 0.55 for the processing stage, but scale efficiency (SE) is high at both stages (0.84 and 0.87), ...
