Institutional factors affecting irrigation performance in Pakistan: research and policy priorities
Provedor de dados: 31
Autores: Bandaragoda,   Don Jayatissa; Firdousi,   G.R.
The strong irrigation tradition has sustained the broad based community interest in irrigation. The result is a very complex institutional milieu in which a set of formally established irrigation rules and organizations exists side by side with an intricate set of social institutions. The two sets act like a dual system often in conflict with each other. The authors, while analyzing the present institutional barriers, have highlighted the importance of irrigation rules and procedures in the institutional framework.

Productivity and performance of irrigated wheat farms across canal commands in the Lower Indus Basin
Provedor de dados: 31
Autores: Hussain,   Intizar; Marikar,   Fuard; Jehangir,   Waqar Ahmed.
A study of the enormous differences in agricultural productivity that exist across farms and regions in Pakistan, where, for example, recent farm-level data from Sindh, indicates that irrigated wheat output per hectare varies from 0.5 to 5.4 tons across farms. Looks at the central goal of agricultural policy in the country, viz. improving and sustaining productivity, narrowing the existing productivity gaps, and enhancing resource use efficiencies to meet food requirements of a rapidly growing population.

A business performance index model that measures wealth change in Australian farm businesses
Provedor de dados: 31
Autores: Sefton,   Clive A.; Cox,   Rodney J.
This paper presents an evaluation of a farm-business assessment model that uses financial performance measures and tracks ‘wealth change’ to evaluate performance trends over time, and ranks the relative business performance of commercial participants. Its core component involves the use of comparative analysis, which is structured as an introductory rapid-assessment model, together with a ranking system that has been designed to differentiate the relative performance levels of farm businesses. The system has been labelled as the Business Performance Index (BPI) model to reflect its performance-ranking role that explores the relationships, if any, between farmer attitudes and business performance. The BPI model is discussed within the context of the debate...

Balanced Scorecard in Serbia: management innovation or rhetoric game
Provedor de dados: 31
Autores: Bogicevic,   Jasmina; Domanovic,   Violeta.
In performance measurement and management literature, the Balanced Scorecard is the most prominent model. It can be considered as effectiveness measurement, efficiency measurement or performance measurement model. The Balanced Scorecard is one of the newest management innovations and it is in focus of contemporary researchers’ attention in management innovation area. The question is if it is something real new in its essence, or just rhetoric came. This paper considers this issue in Serbia, especially.

A gender performance indicator for irrigation:  Concepts, tools and applications
Provedor de dados: 31
Autores: van Koppen,   Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

Performance evaluation of a bush mango (irvingia gabonensis) nut cracking machine
Provedor de dados: 111
Autores: AVIARA, NDUBISI A.; Iyilade, Idowu J.; Oyeniyi, Samuel K.; Aremu, Ademola K.
A bush mango (Irvingia gabonensis) nut handling machine was developed to ease the tedium involved in the cracking operation and enhance the efficiency of separating the kernels from hulls. The machine consists of a hopper, cracking unit barrel, electric motor, blower, tool frame, hull outlet and kernel outlet. It operates on the principle of impact using centrifugal force from the baffles on a spinning disc. Results of performance tests carried out using nuts at four moisture levels in the range of 7.52-20.6% (d.b) showed that percent effective cracking decreased, while percentage kernel breakage increased with increase in feed rate, moisture content and resident time of nuts in the cracking chamber. Winnowing efficiency increased with feed rate and...

Autores: ADEBUKOLA, ADENIGBA ADEMOLA.
Abstract A Fish feed mixing machine was designed, developed and the effect of speed and retention time on the performance of the mixer was evaluated. The mixing system was tested using three fish feed ingredients; bone meal, groundnut cake and maize grain which was purchased from the market in Akure, Ondo State, Nigeria. The moisture content of the bought ingredients was determined to be 13.1%, 14.7% and 17.5% moisture content dry basis respectively. The mixer was tested using a feed component of three equal measures of 10 kg of ground corn (maize), milled groundnut cake and bone meal which were initially retained on 2 mm, 850 µm and 150 µm sieve respectively. The experiment was replicated thrice at four retention time (5 min, 10 min, 15 min and 20 min)...

Developing a mixed solar drier for improved postharvest handling of food grains
Provedor de dados: 111
Autores: DHANDE, HIMANSHU KISHOR; SHELARE, SAGAR DNYANESHWAR; KHOPE, PRAVIN BALKRUSHNAJI.
Drying of grain is usually achieved by spreading grains on earth for solar radiation. This technique is moderate, but being unsecured from a downpour, dust, invasion of bugs, rodents, and distinct animals, items might be severely degraded to the degree that occasionally becomes contaminated and issued loss of nourishment excellence. To defeat this, solar drying is the greatest assuring technique for the protection of agricultural commodities. In the proposed research, the low-cost mixed-mode solar dryer was developed (Workshop of Dr. D. Y. Patil Institute of Technology, Pimpri, Pune, Maharashtra, India) using locally accessible, environmentally friendly materials, and the performance was evaluated. The solar dryer was developed using the components like a...

Autores: Sobowale, Sunday Samuel.
The aim of this study was thus to design, construct a multi-purpose twin screw extruder and evaluate its performance. All parts of the extruder were constructed using locally available materials and its suitable for both batch and continuous production. The extruder essentially consists of the hopper, barrel, variable speed and temperature control, electrical motor and replaceable dies to give different sizes and shapes in the final products. It could also handle feed materials of different rheology. Performance evaluation of the extruder was done using cocoyam flour, varying feed moisture content (FMC) and screw speed (SS). Both the FMC and SS were observed to significantly affect the all performance indicators (expansion ratio, residence time, throughput...

Development of a motorized yam slicer
Provedor de dados: 111
Autores: Samuel Enyi Obetta; University of Agriculture, Benue State, Nigeria.; J. C. Ehiem.
A motorized yam-slicing device was designed and developed to improve drying by increasing the surfaces area of yam tubers.  It consists of rotary blades, feeding chutes and electric motor.  The operating power was obtained from 1.5 hp electric motor (1,400 rpm) and, using pulley and belt with complete drive.  The device is manually fed with one tuber at a time.  Performance of the device was evaluated using the following parameters: slicing efficiency, throughput and percentage of non -uniform slices.  The slicing efficiency, throughput and non-uniform slices obtained was 52.3%, 315 kg/h and 47.65% respectively.  Making the chute adjustable to different tuber thickness would eliminate wobbling and further reduce the percentage of non-uniform slices.
