We conducted an experiment to find out the influence of different level of inorganic fertilizer and bio-formulations on nutrient uptake, crop growth and productivity of kharif groundnut in the Red and Laterite soils during 2018, 2019 and 2020. It was hypothesized that judicious application of inorganic fertilizer and bio-formulation would result in better nutrient uptake, improving nut yield and net income. We found that higher dose of inorganic fertilizer along with liquid bio-formulations yielded better results in terms of nutrient uptake, crop growth, yield and quality in groundnut. An increase of 43.2% and 57.5% in haulm and kernel N uptake; 67.6 and 98.1% in haulm and kernel P uptake; 47.4% and 57.6% in haulm and kernel K uptake was recorded, respectively, when 100% recommended dose of NPK (F4) was coupled with liquid NPK bio-formulation + Zn-solubilizing bacteria (B2) over control and was most economical (higher B:C ratio, 2.73).

A pot experiment was conducted with soil from 2-, 4-, and 8-years fallows of alder-based (N2-fixed) and traditional Jhum agroecosystems, grown with surface-sterilized local French beans (design: CRD). A factorial micro-plot field experiment was also set up in alder-based Jhum sites in 2-, 4-, and 8-years fallow. In both, soil physico-chemical and biological properties, root nodulation and yield attributes of French beans were studied. Root nodulation and biomass yield attributes were higher in alder-based systems compared to traditional, with comparable improvements seen in shorter fallows. At harvest, yield parameters were in the order of 4->2->8-years in alder-based and 8->4->2-years in traditional Jhum soil.

Cadmium (Cd), chromium (Cr), lead (Pb), and nickel (Ni) in grains were below international standards even after maximum dose of sludge treatment and can be declared as safe for consumption. The bioconcentration factor of Cd and Ni increased by 82% and 49% with 10 t ha−1 over control, respectively while it remained same for Cr and Pb. Significant increase in exchangeable Cd, Pb in carbonate, and easily reducible oxide, Ni and Cr in residual fraction with 10 t ha−1 sludge over control were found. Mobility of only Pb and Cd increased with increasing sludge treatment. Conclusively, sludge application can be beneficial in increasing plant biomass, however heavy metal accumulation in plants may limit its use.

SAP containing calcium carbonate (Ca-SAP) is considered to be more resistant and provide more plant AW under saline conditions compared to conventional SAP (C-SAP) and to control. This research investigated two replicated lettuce trials to evaluate three treatments (Ca-SAP, C-SAP and control) subjected to irrigation water with electrical conductivities of 0.0, 0.5, 1.0, 2.0 and 4.0 dS m−1. Both SAP treatments increased AW by an average of 0.16 m3 m−3 as compared to the control. Decrease in AW with salinity was lower in Ca-SAP (0.07 m3 m−3) as compared with C-SAP (0.13 m3 m−3). Lettuce fresh weight (g plant−1) was higher for Ca-SAP (22.9) as compared to C-SAP (16.4), however, did not differ from control (20.6). As water salinity increased, lettuce fresh biomass was higher in Ca-SAP as compared to C-SAP up to 2 dS m−1 with no significant differences from control. The Ca-SAP is less affected by salts than the C-SAP, although its use did not benefit lettuce growth under saline conditions as expected.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"3375 - 3387"},"PeriodicalIF":2.4,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48410165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Principal component analysis revealed a close association among growth traits, plant pigments, fluorescence parameters, total Zn and P concentration, and uptake with total biomass as influenced by ZnO-NPs. Thus, compared to conventional ZnSO4 and higher dosages of ZnO-NPs, foliar-spray of ZnO-NP at 50 mg kg−1, seed-coating at 100 mg kg−1, or soil-drench at 150 mg kg−1 increased maize biochemical characteristics, growth, biomass, and Zn agronomic efficiency.

In this study, NHA was produced from six organic feedstocks, including coal, leonardite, municipal waste compost, sewage sludge, and apple and beech biochars via nitration using nitric acid. The nitration process was conducted in two ways: (i) after humic acid (HA) extraction (NHAD), and (ii) before HA extraction (NHAID). The prepared NHAs were then characterized using FT-IR and CHNS analysis. Additionally, N mineralization of NHAs was investigated in a sandy loam soil sample. The FT-IR spectra showed that both methods of nitration loaded nitro (NO2) groups into the HA structure. However, the CHNS analysis indicated the highest rate of N increase for NHAD (106%) and NHAID (113%) extracted from leonardite. Moreover, on average, the total acidity and carboxylic groups of the HAs increased by 7.5% and 14.5% after the nitration processes, respectively. The highest extraction yields of NHAD (26.1%) and NHAID (42.1%) were also obtained from leonardite. Although the extraction yield of NHAID was on average two times higher than that of NHAD, NHAD indicated a higher soil N availability (1.4 times).
