Rice is one of the high water consuming crops and it is important to utilize methods in its production to promote water use efficiency. In order to achieve this purpose, a split plot experiment was conducted in direct-seeding of rice in Kazerun region of Fars province, Iran, in 2007. Five irrigation treatments (full-season flooding, full-season alternating, flooding until tillering stage, flood...

Today, one of the biggest challenges facing the world is the lack of water, especially in the agricultural sector. In this research, we investigated the effects of irrigation method and deficit irrigation with the urban refined effluent on biomass, grain yield, yield components and water use efficiency in single grain crosses 704 maize. This research was carried out in a randomized complete blo...

Abstract: To investigate the effect of nutrition management along with zeolite application on the fertilizer use efficiency and irrigation water productivity of two cultivars of maize under deficit irrigation conditions, a field experiment was carried out. The experiment was conducted at Soil and Water Research Institute, Karaj, Iran, in 2015 and 2016, in the form of a   factorial split plot...

Because of limiting water resources and increasing demand for food, it is necessary to investigate the effect of irrigation systems on water productivity. This research was conducted to evaluate yield and yield characteristics of two potato varieties under sprinkler and trickle irrigation systems. The treatments were two irrigation systems (sprinkler and trickle irrigation) and two potato varie...

In tea plantation regions of northern part of the country, application of supplemental irrigation during dry periods (lacking rainfalls) in conjuction with proper nitrogen fertilizer application can significantly improve tea yield per unit of plantation area. In order to quantify the effectiveness of proper irrigation and nitrogen management on tea, the response of tea to various levels of irri...
