EFFECT OF SUPER ABSORBENT POLYMER ON QUANTITATIVE AND QUALITATIVE TRAITS OF COWPEA (VIGNA UNGUICULATA L.) IN LOW IRRIGATION MANAGEMENT CONDITIONS

Effect of super absorbent polymer on quantitative and qualitative traits of cowpea (Vigna unguiculata L.) in low irrigation management conditions

IntroductionBeans are the major part of the diet of many people in the world, because the large amounts of protein in combination with cereal grains could provide a valuable source of food.Iran is located in dry and semi-arid region, and water deficit due to the drought are observed in most parts of Iran.Therefore, implementation of irrigation tech

Design Improvement of Stuffing Box Seals of Centrifugal Pump Shafts, Based on the Study of the Sealing Mechanism Physical Model

Stuffing box seals are the most common type of pump rotor seals because they are adjustable and periodically restorable assemblies during operation.Based on the study of physical processes, a sealing mechanism model of the stuffing box seal is formed as a combination of two successive hydraulic resistances: a pre-switch resistance, which is similar
