Genotypic Variation for Productivity, Zinc Utilization Efficiencies, and Kernel Quality in Aromatic Rices Under Low Available Zinc Conditions

Yield and nitrogen use efficiency of aromatic rice varieties in response to nitrogen fertilizer

“…Susamma et al (2005) evaluated the performance of 12 aromatic rice varieties/cultivars and showed that 'Pusa Basmati1' obtained the highest paddy yield of 2.8 Mg/ha which was statistically similar to that of 'Jeerakasala' (2.7 Mg/ha and IET12606 (2.6 Mg/ha), implying the suitability of these three varieties for cultivation in Ambalavayal, Wayanad district. The Basmati varieties have yield potential of 4.5 -6 Mg/ha but on farm yields range from 2.0 to 2.8 Mg/ha (Ahmad et al, 2005;Shivay et al, 2010). Aromatic rice consumption has increased in recent years and the possibilities for export offer an opportunity to increase the production (Das and Baqui, 2000).…”

Nitrogen and Zinc Interaction Improves Yield and Quality of Submerged Basmati Rice (<i>Oryza sativa</i> L.)

“…There is a big difference in the yield potential of different rice varieties and the actual yields obtained by the farmers. The yield potential of Basmati varieties ranges from 4.5 to 6 t ha -1 while the farm yields vary between 2.0 to 2.8 t ha -1 (Ahmad et al, 2005;Shivay et al, 2010). Basmati rice is also an important export commodity of Pakistan.…”

“…So, quality of Basmati rice is next to rice production. Among major constraints of quality and paddy yields in rice, imbalanced nitrogen fertilization (Wang et al, 2008) and zinc deficiency (Shivay et al, 2010) in soils are the most important variables. Zinc (Zn) deficiency in staple foods is a major threat in combating malnutrition related health problems in many developing countries (Impa et al, 2013).…”

Kernel quality and morphological traits of scented rice (cv. Super Basmati) in relation to irrigation and zinc application

“…Crusciol et al (2003) studied effects of irrigation levels on the quality and grain nutrient content of upland rice and found synergistic effects. Zinc (Zn) deficiency in rice has been reported from all over the world (Mirzavand, 2007), and is a barrier in achieving yield targets in crops particularly in rice growing areas (Shivay et al, 2008(Shivay et al, , 2010. Its deficiency causes a considerable reduction (25 to 50%) in paddy yield, so its application at proper time and quantity has a vital importance for maximizing production of rice (Ahmad et al, 2005;Hussain et al, 2005).…”

“…In Pakistan it holds second position in consumption after wheat and is grown on an area of 2963 thousands hectares, with an annual production of 6952 thousand tons, having an average yield of 2346 kg ha -1 (GOP, 2009). The yield potential of Basmati varieties ranges from 4.5 to 6 tha -1 while the actual yield of Basmati varieties obtained by the farmers is 2.0 to 2.8 t ha -1 (Ahmad et al, 2005;Shivay et al, 2010). Water scarcity is increasing in the world (Xie et al, 2008).…”
