Boosting Rice Production Through Narrowing of Exploitable Yield Gap

Documenting production process and the ranking factors causing yield gap in rice fields in Sari, Iran

The documentation process is very important for identifying yield constraint factors and yield gap. For this purpose, all managing practices were recorded by monitoring of paddy rice fields in Sari region, Iran from 2015 to 2016. Field identifications were undertaken in such a way that they included all the main production procedures with variations in management viewpoints. The results reveale...

Identification of production constraints and yield gap monitoring of local rice (Oryza sativa L.) cultivars in Mazandaran province

One of the main problems for rice production is the large difference between farmers' actual yields and attainable yields. Therefore, it is important to identify the limiting factors on yield and yield gap. In this research, all performed management practices from seedbed preparation to harvesting in 228 paddy fields of local rice cultivars in the east, central and west parts of Mazandaran prov...

Production Factors Impacting Rice Milling Yield

Aprevious chapter addressed the general procedure for conducting a laboratory milling analysis and factors that impact the measure­ ment of milling yield, specifically milled rice yield (MRY) and head rice yield (HRY). These factors include the rice sample moisture content, temperature and milling ease, as well as laboratory mill settings and the duration for which the rice is milled. The impac...

Narrowing the gap.

Since 1981 AIDS has illuminated, like a roving searchlight, a series of ethical questions, which extend far beyond the apparently narrow limits of one disease. It has revealed, one by one, human attitudes and behaviours that were previously unquestioned, or unobserved based on unidentified but shaky pre-suppositions. This commentary oVers two contrasting perspectives on the problems facing deve...
