The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...

Goji berries ( Lycium barbarum L.), widely planted in arid to semi-arid regions, are a functional resource characterized by homology of medicine and food. Changing extensive water fertilizer management practices drip fertigation is one the most cost-effective ways achieve sustainable development berry industry. This study explores effects different combinations on soil organic carbon pool L. yi...

A field experiment conducted to standardize the fertigation in papaya (Carica L.) variety Arka Prabhat with 12 treatments split plot design, indicated that 75% recommended fertilizers (250:250:500 g NPK/plant/year) through water soluble recorded significantly higher fruit yield (47.34 t/ha), fertilizer use efficiency (20.45 kg yield/kg of nutrient applied) and increase 31% over soil application...

The field experiment was conducted to elicit information on the yield and nutrient uptake of elephant foot yam [Amorphophallus paeoniflorins (Dennest.) Nicolson] under fertigation at orchard, Department Vegetable Crops, TNAU, Coimbatore during year 2012-2013. laid out in randomized block design with three replications. growth attributes viz., plant height, canopy spread, leaf area, pseudo stem ...

water and nutrient absorption by plants is one of the most conspicuous factors which seriously affect plant productivity. improving physical properties of soilless media and their water retaining capacity can improve plant's nutrient absorption, growth and subsequent yield. in this study, we tried to improve plant nutrient absorption through incorporation of hydrogel into growth media and ...

The purpose of this study is to investigate the interactions between irrigation and fertilizer treatments on soil NO3 (-)-N content and vertical distribution under drip fertigation in greenhouse tomatoes. Randomized block design with three replications and the treatments consisting of three levels of irrigation and three levels of N fertilizer were used. Three irrigation levels were W1 (100%  E...

A field experiment to study the influence of fertigation of N, P and K fertilizers on biometric characters of cocoa (Theobroma cacao L.) was conducted at the Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during January 2010 to December 2011. The experiment was laid out with thirteen treatments replicated t...

Intensive forestry may reduce net CO2 emission into atmosphere by storing carbon in living biomass, dead organic matter and soil, and durable wood products. Because quantification of belowground carbon dynamics is important for reliable estimation of the carbon sequestered by intensively managed plantations, we examined soil CO2 efflux (SCO2 ) in a 6-year-old loblolly pine (Pinus taeda L.) plan...
