The study was carried out in two intensive potato growing areas (Rangpur and Munshigonj) to estimate the technical efficiency of potato producers and to describe the level of variation in potato productivity due to differences in input use. Data were collected from 60 farmers (30 farmers from each district) using simple random sampling technique. Average technical efficiency was 86% implying th...

Potato is one of the staple crops cultivated in upland farming in Japan and is propagated vegetatively by means of tubers. However once infected with diseases, potato yield decreases significantly. And one seed potato can produce approximately only 10 potato tubers. To improve the production system of seed potatoes in Japan, Japanese government established a three-stage propagation system for t...

This study investigated the mechanisms of seed potato management by potato growers of Freydunshahr County in Isfahan province. Survey research method was used in this study. A sample of 250 potato growers (N=725) was selected for data collection. Stratified random sampling method was used. The research instrument was a questionnaire that was validated for face validity by a panel of faculty mem...

The capacity of Cryptococcus spp to produce melanin in media containing phenol compounds is widely used for identifying these species in the laboratory. The aim of the present study was to compare the production of this pigment by Cryptococcus spp. in four culture media. Sixteen strains of Cryptococcus neoformans, 17 of Cryptococcus albidus, 13 of Cryptococcus laurentii and two of Cryptococcus ...

Agricultural Training Centres (ATCs) promote crop and livestock development by providing extension information to farmers and serving as models of improved crop and livestock husbandry practices. Although potato farmers in Nyandarua County were trained on potato production technologies, their average yield was ≤16 tonnes per hectare compared to the national potential of 30 tonnes. This study th...
