Using the PILOTE Model to Improve Water Productivity for Rice in Rasht, North of Iran

In order to calibrate and validate the PILOTE model for rice in a humid climate, this study was carried in a randomized complete block design with three replications on a popular local variety, Hashemi, during 2001, 2002, 2005, 2006 and 2007 crop seasons. This research was done at the Rice Research Institute of Rasht, Iran. Evaluation of simulated and measured grain yield and dry matter values ...

Combine Use of Fly Ash and Rice Husk Ash in Concrete to Improve its Properties (RESEARCH NOTE)

This research paper describes the study of combined effect of Fly Ash (FA) and Rice Husk Ash (RHA) on properties of concrete as partial replacement of Ordinary Portland Cement (OPC). These by-products are having high pozzolanic reactivity. In this research, the composition of mix was used with 10% RHA along with 10, 20 and 30% FA as partial replacement of cement. In this study, the compressive ...

Influence of Crop Residues under Rice Planting and Nutrient Management on Soil Microbial Dynamics and Productivity of Chickpea in Vertisols

Growth and Productivity Response of Hybrid Rice to Application of Animal Manures, Plant Residues and Phosphorus

The objective of this research was to evaluate the impact of organic sources (animal manures vs. plant residues at the rate of 10 t ha-1 each) on the productivity of hybrid rice (Oryza sativa L.) production under different levels of phosphorus (0, 30, 60, and 90 kg P ha-1) fertilization. Two separate field experiments were conducted. In experiment (1), impact of three animal manures sources (ca...
