Relative performance of neem (Azadirachta indica) coated urea vis-à-vis ordinary urea applied to rice on the basis of soil test or following need based nitrogen management using leaf colour chart (2010, background): “…assess foliar N status and adjust top dressing accordingly as it is proved that the current recommendation of three split application at specified growth stages is not adequate to synchronize N supply with crop N demand (Bijay-Singh et al. 2002; Shukla et al. 2004; Alam et al. 2005, 2006).”
Need based nitrogen management using the chlorophyll meter and leaf colour chart in rice and wheat in South Asia: a review (2010, methodology): “Spaner et al. (2005) and Shukla et al. (2004) have successfully used leaf chlorophyll concentrations estimated by SPAD meter for assessing the N status in wheat.”
Breeding for Yield Potential and Stress Adaptation in Cereals (2008, methodology): “Thus, IRRI in collaboration with the NARS, has developed a multi-panel leaf color chart developed and calibrated for use with rice throughout Asia ( Shukla et al , 2004 ; IRRI 2005).”
Establishment of threshold leaf colour greenness for need-based fertilizer nitrogen management in irrigated wheat (Triticum aestivum L.) using leaf colour chart (2012, methodology): “Shukla et al. (2004) used LCC shade 4 as threshold greenness for guiding fertilizer N applications at each of the four irrigation events.”
Environmental impact and economic benefits of site-specific nutrient management (SSNM) in irrigated rice systems (2007, methodology): “The LCC is an inexpensive and simple tool for monitoring the relative greenness of a rice leaf as an indicator of leaf N status, and then enabling farmers to apply fertilizer N whenever leaves reach a critical N status determined by their yellowish-green colour (Peng et al., 1996; Shukla et al., 20”
On-farm evaluation of leaf color chart for need-based nitrogen management in irrigated transplanted rice in northwestern India (2007, methodology): “Although shade 4 on the LCC has been used in Asia (Bijay-Singh et al. 2002; Balasubramanian et al. 2003; Shukla et al. 2004; Alam et al. 2005) as the critical value for deciding N fertilizer application on the basis of the color of the first fully opened leaf of the rice plant from the top,…”
