“…Significantly higher P accumulation was recorded in all N treatments than control. Similar finding on higher concentration of P in rice crop was earlier given by Shinde et al (2017) [21] ; Latha et al (2019) [13] and Meetei et al (2019) [15] . The increased P content might be due to gradual release of nutrients from organic sources thereby increasing soil nutrients along with inorganic source and made available during the growing season.…”

“…Grain and straw also observed the significantly higher N content with N treatments than control. The finding was also given by Nongmeikapam and Devi, 2018 [16] and Meetei et al, 2019 [15] . The pooled data revealed that statistically higher N content was observed in T 8 on 30, 60 and 90 DAT which was at par with T 2 and T 10 and only with T 10 on 90 DAT.…”

“…A decreasing trend in P content (Table 3) in rice with increased in crop growth in both the years as well as in pooled. P content decline with crop growth advancement was also observed by Liu and Zhu (1996) [14] ; Latha et al (2019) [13] and Meetei et al (2019) [15] . The decrease in P content with the advancement of crop growth might be due to three reasons: dilution effect, caused by higher dry matter production, low P status of soil or fixation of applied P (Meetei et al, 2019) [15] .…”

“…Similar effect of treatments T 8 and T 10 in straw N content was also recorded. The improvement in N content in organic treatment along with inorganic source might be slow release of nutrients to the soil along with inorganic source and made it available throughout the growing period (Helgason et al, 2007;Baitilwake et al, 2012 and Meetei et al, 2019) [7,3,15] .…”

A field investigation was carried out during kharif seasons of 2016 and 2017 at research farm of College of Agriculture, Central Agricultural University, Imphal, to study the influence of integrated nutrient management on dry matter production, yield and NPK content of transplanted rice. The treatments were laid out in a randomized block design and replicated thrice using the rice variety (CAU-R1). Among the different treatments, higher dry matter production and N content in rice were found significantly in T8 (100% RDN from urea + 10 tonnes Azolla ha -1 ) on 30 th , 60 th and 90 th DAT. At harvest, significantly higher content of N in grain was observed in T10 (75% RDN from urea + 25% RDN from FYM + 10 tonnes Azolla ha -1 ) while treatments T8 and T10 showed the similar effect in straw N content. However, statistically higher P concentration was recorded in T11 (50% RDN from urea + 50% RDN from FYM + 10 tonnes Azolla ha -1 ) throughout the growing period and also in grain and straw at harvest time. T12 (25% RDN from urea + 75% RDN from FYM + 10 tonnes Azolla ha -1 ) noted the highest K concentration in grain followed by T11 while K content in straw was highest in both the treatments T11 andT12. In contrary to P content, the K content recorded in grain was low under different treatments. Critical analysis of the pooled data showed that soil treated with 75% RDN from urea + 25% RDN from FYM + 10 tonnes Azolla ha -1 (T10) yielded significantly higher grain and straw yield of rice.
