Fertigation Frequency for Subsurface Drip-Irrigated Broccoli
Yosef and Sagiv, 1982; Stark et al., 1983; Burt et al., 1995). However, very few studies have shown a benefit Subsurface-drip irrigation and fertigation with fluid N fertilizer of frequent or continuous fertigation compared with sources offers substantial flexibility for N fertilizer management. Fertiless frequent fertigation. Bar-Yosef and Sagiv (1982) gation events can be scheduled as often a...
متن کاملDetermination of Crop Water Use and Crop Coefficient of Two Hybrids of Sunflower (Euroflor and Sirna) under Drip-Tape Irrigation System
The purpose of this study was to measure daily and seasonal evapotranspiration and daily crop coefficient of two common varieties of sunflower (Sirna and Euroflor) via drip-tape irrigation system. For this purpose, the sunflower water use was determined by daily monitoring of soil moisture at the depths of 10, 20, 30, 40 and 60 cm, and the crop evapotranspiration (ETC) was measured using volume...
متن کاملEffect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
متن کاملLint yield and seed quality response of drip irrigated cotton under various levels of water
Restricted water resources are a limiting factor for irrigation applications throughout the world. The effects of irrigation regimes (amount) on cotton lint yield are known, but there is little information on the effect of irrigation regimes on seed quality of cotton. In this study, the effects of deficit irrigation after the onset of flowering on lint yield and seed quality of cotton (Gossypiu...
متن کاملThe Effect of Different Traits on Yield and Water Productivity in Surface and Subsurface Drip Irrigation of Kabkab Variety
Increasing crop production per unit volume of water consumption requires recognizing the most dependent variable in drip irrigation to the volume of water consumption and also identifying the most important variables independent of water productivity in surface and subsurface drip irrigation for optimal use of available water resources. The present research was carried out in Behbahan Agricultu...
