Yield and nutrient uptake of summer green gram [Vigna radiata (L) Wilczek] under different levels of phosphorus and Sulphur fertilizations

Abstract

A field experiment was conducted at Krishi Vigyan Kendra, Dungarpur (Rajasthan) during summer seasons of 2010 and 2011 on sandy clay loam soil to investigate the effect of phosphorus (control, 10, 20, 40 and 60 kg P2O5 ha-1) and sulphur (control, 15, 30 and 45 kg S ha-1) application on NPK and S uptake by green gram [Vigna radiata (L) Wilczek]. Increasing levels of phosphorus up to 60 kg P2O5 ha-1 resulted in significantly higher grain (745 kg ha-1) and stover (1245 kg ha-1) yields and uptake of NPK and S by grain, stover and the whole plant over lower levels of phosphorus during both the years of the study as well as on pooled basis. But it was at par with 40 kg P2O5 ha-1 in respect to S uptake by grain during 2011, S uptake by stover during both the years and total S uptake during 2011. 45 kg S ha-1 produced significantly higher grain (743 kg ha-1) and stover (12264 kg ha-1) yields and uptake of NPK and S by grain, stover as well as total uptake over lower levels of sulphur during both the years of the investigation and on pooled basis. Interaction effect was significant in respect to total NPK and S uptake on pooled basis. Combined application of 60 kg P2O5 ha-1 and 45 kg S ha-1 resulted in significantly higher uptake of total NPK and S by summer green gram DOI: http://dx.doi.org/10.3329/sja.v12i1.21122 SAARC J.

Response of Greengram to Different Level of Phosphorus and Organic Liquid Fertilizer on Yield, Quality, Nutrient Content and Uptake

“…Similar trend was also observed in case of total uptake of nitrogen, phosphorus and potassium by crop. These results are in accordance with Gangaiah and Ahlawat ( 2008), Ghanshyam et al, (2010), Singh and Singh (2012), Singh et al, (2013), Bairwa et al, (2014) and Nyekha et al, (2015).…”

Response of Different Sulphur Sources and Levels on Nutrient Content, Its Uptake, Nutrient Use Efficiency and the Availability of Sulphur in Post-Harvest Soils of Green Gram

“…The findings indicate that S uptake by greengram is significantly influenced by S levels as compared to sources. The results were supported by the findings of Bairwa et al (2014); Bera and Ghosh (2015); (Singh, 2017) in green gram and in mustard.…”

Effect of foliar application of micronutrients and urea on mungbean varieties

“…That means, all the treatments performed better than control. Bairwa, et al [7] in his study, made similar report on chlorophyll content. Interaction effect of variety and treatment on chlorophyll content showed variation.…”
