Performance of rice varieties in relation to nitrogen levels under irrigated condition

Abstract

The field experiment was conducted at the research farm College of Agriculture, JNKVV, Rewa M.P. during kharif season 2011 to study the performance of rice varieties and relation to nitrogen level under irrigated conditions. Twenty one treatment combinations, comprising three nitrogen levels (40, 80 and 120 kg ha-1), followed by IET 21278 (56.78 q ha-1) and obtained net income Rs. 40871 ha-1 and Rs. 38983 ha-1 , respectively.

Ffect of Nitrogen Dose on Growth, Development, Productivity and Nutrient Use Efficiency in Rice (Oryza Sativa L.) – A Review

“…Whereas much higher number of tillers were recorded through application of 150 kg N ha -1 as reported by Ramesh et al (2009). Similarly, positive response to Nitrogen application has been reported by Shukla et al (2015) at 120 kg N ha -1 with effective tillers (238.50 m -2 ), Kumar et al (2017) at 150 kg/ha (9.25 EBT hill -1 ) under aerobic condition and Dahipahle and Singh (2018) at 180 kg N ha -1 (12.6 EBT hill -1 ) under puddle soils.…”

“…Saha et al (2017) found 90 kg N ha -1 producing significantly higher (4.96 t ha -1 ) straw yield. Shukla et al (2015) found a nitrogen dose of 120 kg N ha -1 exhibiting the maximum harvest index (34.84%). Saha et al (2017) also reported higher (44.80) value of harvest index at 90 kg N ha -1 followed by 60 kg N ha -1 (40.80 %) and 30 kg N/ha (36.80%).…”

“…Kadiyala et al (2012) observed improvement in panicle production with increased N application and more response to incremental rates of N in flooded conditions than aerobic rice treatments. Shukla et al (2015) revealed that 120 kg N ha -1 recorded maximum number of effective tillers (238.50 m-2) over 40 kg N ha -1 (160.88 m -2 ) and 80 kg N ha -1 (182.37 m -2 . Application of 100 kg N ha -1 produced significantly higher panicle weight (Patel et al, 2010).…”

“…The results are in conformity with the findings of Sharma et al (2007) who also reported a strong positive relationship between apparent recovery efficiency of nitrogen and nitrogen levels. Shukla et al (2015) reported that crop fertilized with 120 kg N ha -1 had higher B:C ratio (2.27)over 40 kg N ha -1 (1.81)and 80 kg N ha -1 (2.00). Similar findings were also observed by Singh et al (2017) that among the different nitrogen levels, the maximum benefit: cost ratio of 2.34 can be recorded with the application of 120 kg N ha -1 over 180, 60 and 0 kg N ha -1 .…”

Incidencia Y Severidad Del Daño Por Hongos en Líneas De Arroz Sometidas a Dosis De Fertilización

“…Más aún, el cultivo de arroz puede acumular alrededor de 7.3 t ha -1 con 10 % de fertilización recomendada del paquete tecnológico de INIFAP. Resultados similares fueron reportados por Shukla et al (2015) y Jana et al (2017), los cuales registraron mayor altura de planta al aumentar los niveles de fertilización. Investigaciones han demostrado que el nitrógeno potencializa el crecimiento de arroz y la mayor concentración de este elemento se encuentra en hojas y tallos (Wang et al 2018).…”
