modeling of crop growth plays an important role in evaluation of drought impacts on rainfed yield, choosing an optimum sowing date, and managerial decision-makings. aquacrop model is a new crop model that developed by food and agriculture organization (fao), that is a model for simulation of crop yield based on “yield response to water“ with meteorological, crop, soli and management practices d...

Accurate quantification and clear understanding of regional scale cropland carbon (C) cycling is critical for designing effective policies and management practices that can contribute toward stabilizing atmospheric CO2 concentrations. However, extrapolating site-scale observations to regional scales represents a major challenge confronting the agricultural modeling community. This study introdu...

Background and Objective: Attention to on-farm food safety is the first step in achieving food safety and production of healthy crops. However, practices related to on-farm food safety are not sufficiently considered by farmers due to the lack of proper understanding. Accordingly, the purpose of this study was to evaluate the attitude of farmers about sources of contamination and explaining fac...

Traditional farming practices suggest that cultivation of a mixture of crop species in the same field through temporal and spatial management may be advantageous in boosting yields and preventing disease, but evidence from large-scale field testing is limited. Increasing crop diversity through intercropping addresses the problem of increasing land utilization and crop productivity. In collabora...

The study was conducted among the two farmer groups in Bhaktapur and Kavre districts of Nepal. The main objective of the study is to evaluate the differences in belief, attitude and practices felt by the farmers after participation in the IPM FFS. The study has been based on data collected through personal interview with the farmers, focus group discussion, personal observation in the farmers f...

This paper presents an application of a two and three stages difference in differences model to measure environmental and economic impacts of Farmer Field School on crop and pest management practices of rice in Thailand. Panel data from 241 farm households were collected three times over a period of four years in five rice-producing provinces of Thailand. Data included socio-economic data descr...

With changing climatic conditions the balance in agricultural resources of semi-arid tropics are largely affected. This has led to impacts on the socio economic condition of resource poor cultivators / farmers. Technological advances in Wireless Sensor Networks (WSN) have achieved the capability to seamlessly gather real-time agro-meteorological and environmental data. In order to address the p...

Rising demands for agricultural products will increase pressure to further intensify crop production, while negative environmental impacts have to be minimized. Ecological intensification entails the environmentally friendly replacement of anthropogenic inputs and/or enhancement of crop productivity, by including regulating and supporting ecosystem services management in agricultural practices....

Carbon sequestration in agricultural soils has the capacity to mitigate greenhouse gas emissions, as well as to improve soil biological, physical, and chemical properties. The review of literature pertaining to soil organic carbon (SOC) dynamics within Australian grain farming systems does not enable us to conclude on the best farming practices to increase or maintain SOC for a specific combina...
