Women are involved in planting, transplanting, weeding, harvesting and processing activities in paddy cultivation system. These operations are most drudgeries activities performed by them. During these operations the women face many physical and physiological problems. Keeping this in view the physical strain with respect to working heart rate (WHR), Oxygen consumption rate (OCR), Energy expend...

Semi-arid North-central Namibia has high potential for rice cultivation because large seasonal wetlands (oshana) form during the rainy season. Evaluating the distribution of surface water would reveal the area potentially suitable for rice cultivation. In this study, we detected the distribution of surface water with high spatial and temporal resolution by using two types of complementary satel...

The deficiency of oxygen in water during submergence is one of the frequently perceived environmental factors that limits or hampers production of the rice cultivation. Rice plants comprise of elongated submerged tissues that help to bear with the rise of water level in natural location. This characteristic helps the plant to deal with flooding stress. The mechanism on flooding tolerance and ad...

Rice receives a large amount of water during land preparation and the growing period, causing poor crop water productivity and lower net benefits. In wheat, excessive tillage operations delay its sowing, resulting in low yields and net returns. Dry seeding of rice and zero tillage in wheat can be expected to reduce water inputs and tillage costs compared with the conventional system of rice-whe...

System of Rice Intensification (SRI) management practices depart from conventionallyrecommended methods for rice cultivation, aiming to provide rice plants with optimal growing conditions, to enhance yield and resource productivity (Stoop et al. 2002). The benefits of SRI practices have been seen already in 42 countries and are reported to increase yields of irrigated rice by 25–50% or even mor...
