Influence of Crop Residue and Potassium Management on Yield, Quality, Nutrient Uptake and Nutrient Use Efficiency by Mungbean in Maize (Zea mays L.)-Wheat (Triticum aestivum L.)-Mungbean Cropping System

Abstract

A field experiment was conducted during 2014-15 and 2015-16 on Research Farm of Division of Agronomy, IARI at New Delhi to evaluate Influence of crop residue and potassium management on yield, quality, nutrient uptake and K use efficiencies of mungbean in maize-wheat-mungbean cropping system. The experiment consisted of 15 treatment combinations with three crop residues [no crop residue, crop residue incorporation and fungal consortium incorporation] and five potassium management practices [control, KSB, 100 % RDK, 50% RDK+ KSB and 75% RDK+ KSB]. Results revealed that considerably highest grain yields, protein content, protein yield and N P K concentration both in seed and stalk and its uptake by mungbean were noticed with treatment receiving crop residue incorporation + fungal consortium which was statistically at par with crop residue incorporation. Similar trends were also recorded for K use efficiency, physiological use efficiency, apparent recovery and utilization efficiency during both years of study. Among Potassium management, significantly highest grain yield, protein content, protein yield, N P K concentration, uptake in both seed and stalk and its total uptake were noticed with treatment receiving 75% RDK + KSB which were statistically at par with 50% RDK+ KSB. However, maximum K use efficiency, physiological use efficiency, apparent recovery, utilization efficiency were noticed with treatment receiving 50% RDK+ KSB which were statistically at par with 75% RDK+ KSB as compared to the first year, maximum attributes and efficiencies were observed in the second year of investigation.

Response of crop residue incorporation on Partial factor productivity, recoveries and efficiencies of applied nutrients under maize-wheat cropping system

“…The relationship between grain yield and the N contained in aboveground biomass at physiological maturity provides a measure of PEN across a wide range of production environments. Similar results have been reported by Meena et al (2018) [8] . The nutrient internal use efficiency is defined as amount of grain yield produced per unit of nutrient taken up by the plant (Yang et.…”

Effect of treated sewage water and organic manure on growth indices, phenology, cob dimensions and economics of spring maize (Zea mays L.) in semi-arid region of Haryana, India

“…This might be due to increased fertility levels by continuous availability of nutrients released from organic manure. These results are in agreement with Prasad (2019) and Meena et al (2012). The minimum number of days to maturity was recorded under no manure.…”

Crop Residues Management: A Viable Tool for Sustainable Agriculture

“…Increased yield of green gram, along with higher net returns and B:C ratio was found when wheat residues were incorporated with a fungal consortium [8]. The residue incorporation in all tillage systems like zero, reduced and conventional systems resulted in significantly improved wheat grain yield, productivity of wheat and rice, OC content of soil and B:C ratio under rice-wheat cropping system [9]. "The crop establishment and residue management (CERM) impact on grain yield in rice-chickpea, rice-lentil and rice-safflower, ricelinseed, rice-mustard production systems revealed that ZTDSR (zero-till direct seeded rice) along with crop residue retention can be viable production systems with higher productivity" [10].…”
