Leaf physiology and stem growth were assessed in loblolly pine (Pinus taeda L.) in response to 10 to 11 years of treatment with weed control (W), weed control plus irrigation (WI), weed control plus irrigation and fertigation (WIF), or weed control plus irrigation, fertigation, and pest control (WIFP) to determine whether increased resource availability can push productivity of loblolly pine cl...

For actual needs of increasing crop production and quality in modern agriculture, fertigation is an established approach to implement advanced control schemes. The basic idea of this strategy is to maintain the concentration of specific ions in the recirculated drainage water at a desired level for optimal global function. In this way, nutrients which are uptaken by the plants must be refilled,...

A field experiment was conducted during rabi 2016-17 and 2017-18, at the Research Farm of Department Agronomy, Punjab Agricultural University, Ludhiana, to study phenological behaviour gobhi sarson (Brassicanapus L.) thermal indices as influenced by drip irrigation (60, 80 100% cumulative pan-evaporation, CPE) fertigation schedules 100 % recommended dose fertilizers, RDF) in comparison with con...

Understanding the spatial distributions of soil water, temperature and nutrients as well their effects on maize growth grain yield is vital for optimizing drip fertigation regimes. In this study, a 2 year field experiment was conducted drip-fertigated spring with plastic mulching in arid northwestern China 2015 2016. Four irrigation levels were set: I60 (60% ETc; ETc crop evapotranspiration), I...

Inappropriate fertilization management practices have led to low timber production in intensive plantation systems China. Thus, optimized conventional or advanced are needed. We aimed quantify whether furrow (FF) is comparable drip fertigation (DF) and make recommendations regarding strategies for poplar plantations. A completely randomized block design experiment with two methods (DF FF) four ...

Subsurface drip irrigation is defined as application of water below the soil surface through emitters, with discharge rates generally in the same range as surface drip irrigation. It has many advantages over surface drip. To see the response of subsurface drip irrigation on okra yield, a study was conducted at Indian Agricultural Research Institute, New Delhi, India during 2003 and 2004. Okra (...
