Water Stress in Rice Crops, its Impact on Productivity

"Water stress in the rice crop, its impact on productivity" carried out in dry season of 2016, located in the Junta de Usuarios América-Lomas del cantón Daule province of Guayas, Ecuador. It is important to highlight, that in this research work there were savings of 75% in seed in relation to the farmer (TA); the general average of seed use in the country is 45 kg/ha, for this planting system there is a saving of 64.51%, likewise in the management of irrigation water use there is also a saving of 39.5% (research 726.4 m3 vs producer 1016 m3) with respect to the producer. When planted at a distance of 0.35 x 0.35 m, with two plants per site corresponding to the research (T2) compared with the TA planted at a distance of 0.25 x 0.25 m, and eight plants per site, there is a numerical difference, in which the T2 exceeds the TA by approximately 19%. The T2 treatment (research), had a profitability of 97% on production costs and 49% in sales income in relation to the control (TA) which obtained a profitability of 45% on production costs and 31% in sales income.
