the quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. the per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...

In recent years, methods of fuzzy reasoning have been successfully developed for land evaluation. The accuracy of such land evaluation depends on the quality of weighing land characteristics with respect to their effects on crop production. This paper presents a spatially-based model of land suitability analysis. The main purposes were to (1) establish land suitability indices for irrigated whe...

This paper presents a proposed expert system to identify the leaf diseases of three cereal crops (rice, maize and wheat). Keeping in view the advances in the field of agriculture and need of farmers, this expert system has been proposed. The identification of plant diseases is usually a difficult task and requires a plant pathologist or well-trained technician to accurately describe the case. M...

The sustainability of rice productivity in Bangladesh is likely to face major threat due to water shortage during boro (winter season). The conventional transplanted boro rice requires huge amount of irrigation water due to wastage of various means. It is an imperative task that water saving production technology is needed to replace the conventional system for sustaining boro rice production i...

his study investigated the farmers’ feedback on Agricultural Development Project’s (ADP’s) performance. The study was carried out in Kogi State, Nigeria. Interview schedules were used to collect data from 160 contact farmers and 80 field extension workers who were randomly selected using multistage random sampling techniques. The data collected were subjected to both descriptive and non-paramet...

Only 34% of all German farms apply reduced tillage (RT), while approximately 1% of the arable land is under no-tillage (NT). Statistics for organic farming are not available, but the percentages are probably even lower. The development of German organic RT and NT has been strongly driven by pioneer farmers for 40 years, and supported by field trials since the 1990s. The main motive for conversi...

this research aims at determining and evaluating the water productivity indexes in astan-ghods-razavi companies for different crops during 2007-2008 growth season. required field data were collected during several field surveys. these data consisted of crop yields and crop consumptive water that is irrigated by distinct agriculture well. with regard to collected data, four water productivity in...

Agricultural damage by wildlife is a major concern for both agricultural and wildlife agencies at the state and federal level. Our objective was to estimate wildlife damage to agricultural crops on a statewide basis. We sent questionnaires to 4,958 farmers and 1,003 were returned after 2 mailings. Twenty-five percent of farmers responding to our survey rated the level of wildlife damage to thei...
