Research and development on IPM was initiated in Pakistan in the 70’s. However, efforts to implement IPM at the farm level did not bear fruit. A major obstacle has been the mindset at the policy level to increase crop production to feed the ever-increasing population. Pesticides became a major instrument of increasing production leading to ‘pesticide treadmill’ situation. Although IPM-FFS “Veha...

A study was carried out to determine the problems in IPM practices for rice cultivation faced by the farmers trained in IPM through Farmers’ Field School (FFS) and also to find out the important probable suggestions for overcoming those problems. Data were collected from 158 respondent farmers sampled randomly from 1050 FFS farmers of Godagari Upazila in Rajshahi district. Twenty important prob...

In this paper, we investigate the impact of the Farmer Field School (FFS) intervention among small-scale tomato farmers in Beijing. Using data collected by face-to face-interview from 358 households on 426 planting plots in 2009, we evaluate the yield effect and find evidence of positive impact. We then examine the determining factors of farmers’ FFS attendance using the zero-inflated Poisson m...

Farmer field schools (FFS) originally were developed for rice in Asia by the Food and Agriculture Organization of the United Nations (FAO) for teaching integrated pest management. These were season-long courses involving 25 farmers and a trained facilitator. The main focus was promoting learning by discovery, which included hands-on training activities such as insect zoos and the use of field e...

This paper focuses on a Flexible Flow Shop (FFS) problem in a paint company in an attempt to minimize production makespan. The FFS problem is characterized by multiple products being produced in machines in stages with sequence dependent set up times and infinite intermediate storages. As the FFS problem is computationally complex, two heuristic methods are employed to solve the Mixed Integer L...

PURPOSE To investigate the underestimation of field loss in functional field score (FFS) between the Goldmann isopters III-4e and V-4e in visually impaired patients, in order to develop a predictive model for the FFS(III-4e) based on FFS(v-4e) that adjusts for possible confounders. Although the visual field is generally evaluated using Goldmann isopter III-4e, it has the disadvantage that not a...

The security of pairing-based cryptosystems depends on the difficulty of the discrete logarithm problem (DLP) over certain types of finite fields. One of the most efficient algorithms for computing a pairing is the ηT pairing over supersingular curves on finite fields whose characteristic is 3. Indeed many high-speed implementations of this pairing have been reported, and it is an attractive ca...

A farmer field school programme aims to impart knowledge and promote new technology. The is expected enhance farmers’ performances. However, the empirical evidence remains unclear. few studies have examined impact of this on technical efficiency in Indonesia. current study specifically investigates causal Farmer Field School Integrated Crop Management (FFS-ICM) maize production We used a stocha...

the purpose of this study was to investigate the effect of farmers' knowledge and attitude regarding farmer field school (ffs) on biological control against rice stem borer in mazandaran province. the population of the study included all farmers residing in three villages of kohnedan, rangrizmahalleh and aliabad (n=121). a questionnaire was developed from reviewed literature. the content a...

Fluorescence fluctuation spectroscopy (FFS) quantifies interactions of fluorescently labeled proteins inside living cells by brightness analysis. Conventional FFS implicitly requires that the sample thickness exceeds the size of the observation volume. This condition is not always fulfilled when measuring cells. Cytoplasmic sections, especially, can be thinner than the axial size of the observa...
