Water shortage is a major constraint to sustaining and increasing the productivity of rice-wheat systems. Saving water can be elusive in that reducing seepage, percolation and runoff losses from fields does not necessarily save water if it can be recaptured at some other temporal or spatial scale, for example by groundwater pumping. Many technologies appear to save substantial amounts of water ...

The paddy soil-rice system has efficient nutrient replenishing mechanisms. Basic cations and silica are supplied by irrigation water, while biological fixation works as an inexhaustible source of N in the system, and phosphorus availability is enhanced under anaerobic conditions. This, along with almost perfect resistance to soil erosion, gives the paddy rice system high productivity as well as...

Biomass is an important source of renewable energy in Thailand and currently is the second major energy sources in the country, especially for households and small industries in rural area. It provides basic energy requirement for cooking and process heating in residential and manufacturing sectors as well as for processing in traditional industries. Four major sources of biomass in Thailand ar...

The aim of the research was analysis of rice producers’ perceptions of participatory communication in the use of integrated pest management (IPM). Research population was consisted of rice producers in the west of Mazandaran province (N=16126), whose 187 ones were selected using Cochran’s formula. Data were gathered by systematic random sampling method. The instrument for data collection was a ...

The views expressed in this publication are those of the authors and do not necessarily reflect the views of the Food and Agriculture Organization of the United Nations. Abstract Rice is the first food crop for which complete genome sequence is available. This offers an unprecedented opportunity to identify and functionally characterize the genes and biochemical pathways that are responsible fo...

Male sterility plays an important role in the utilization of heterosis rice. The establishment male sterile lines rice is one key technologies hybrid production systems. currently widely used line breeding systems mainly include: three-line based on cytoplasmic sterility, two-line environmental sensitive gene and third-generation nuclear Seed system. This study reviewed types mechanisms rice, l...

India is the largest producer of rice (Oryza sativa L.) next to China in the world. Rice cultivation is a huge water demanding enterprise. In recent years, water table has depleted at a very rapid rate throughout the globe, thus, posing alarming threats and limiting the scope for cultivation of high water consuming crops especially rice. Challenges in maintaining the sustainability of rice farm...
