Effect of Fertigation Through Drip System on Nitrogen Dynamics, Growth, Yield and Quality of Apricot

Minimal nitrogen and water use in horticulture: Effects on quality and content of selected nutrients

“…Several authors, however, reported that there were no significant effects of N fertilization levels on internal and external fruit quality indices in blackberry (Alleyne & Clark, 1997), peach (Olienyk et al, 1997), apple , apricot (Raina et al, 2005), wine grapes (Neilsen, Stevenson, & Gehringer, 1987), and cherry (Neilsen, Neilsen, Kappel, & Toivonen, 2005). All of these studies, however, were consistent in concluding that N fertilization in fruit production should be reduced to a minimum level without affecting yield, independent of the positive or neutral effects on internal and external quality.…”

“…Leaching of N and phosphorous (P) due to excessive applications in agriculture are widely considered the main cause of eutrophication in fresh and salt water supplies throughout the world (Burt et al, 2009b;Erhart, Feichtinger, & Hart, 2007). Several practices have recently been implemented to try to reduce ground water pollution by N, such as split applications (Drake, Raese, & Smith, 2002), target timing (Tagliavini & Marangoni, 2002;Wade, Holzapfel, Degaris, Williams, & Keller, 2004), integrated production (Ganeshamurthy et al, 2004;Peck et al, 2006), fertigation (Neilsen, Neilsen, & Herbert, 2009;Raina, Thakur, Shashi, & Spehia, 2005), best management practices (Alva, Paramasivam, Fares, Obreza, & Schumann, 2006;, foliar applications (Dong, Neilsen, Neilsen, & Fuchigami, 2005;Reay, Fletcher, & Thomas 1998), and varying the type of N sources (El-Boray, Mostafa, Iraqi, & Mohamed, 2006;Erhart et al, 2007;Racskó et al, 2008;Rosen & Allan, 2007). While not all of the above mentioned practices reduced the total amount of N applied; all were effective in limiting pollution by increasing plant N use efficiency.…”

Various Fertilization Managements Influence the Flowering Attributes, Yield Response, Biochemical Activity and SoilNutrient Status of Chrysanthemum (Chrysanthemum morifolium Ramat.)

“…Drip irrigation produces up to 90% irrigation efficiency, enhances crop yields by 25% to 30% and saves 30% to 50% on irrigation water when compared to traditional irrigation methods [27]. Fertigation enables the consistent distribution of the appropriate proportions of plant nutrients to the moistened root volume zone, where the majority of the functional roots are concentrated, hence improving nutrient usage efficiency [17,28]. It has been discovered that it improves agricultural output and quality while also increasing resource efficiency [29].…”

Effects of fertilization on quality flower production and foliar nutrient content of carnation (Dianthus caryophyllus L.) cv. Master

“…Fertigation is a noble approach that has gained importance nowadays due to availability of better quality water soluble fertilizers for commercial flower production in various greenhouse programmes. Subsequently, fertigation helps in uniform distribution besides better timings for more accurate and timely nutrition leading to better yield and quality and considerable savings in quantity of fertilizers to be used in comparison to conventional fertilizer applications (Bussi et al 1991, Raina 2002, Raina et al 2005. Plant response to foliar applied nutrients is a function of the amount of nutrients absorbed by the leaf tissues, the mobility of the nutrients within the plant and the phytotoxicity of the nutrients solution to the foliage.…”
