This important field study was planned to evaluate the P-S interaction effects on maize growth, fodder yield and nutrient (P and S) uptake. The soil used for study was clay loam, medium-alkaline (pH: 7.9), non-saline (EC: 0.85 dS m-1), strongly calcareous (CaCO3: 24 %), adequate in organic matter (1.6 %), low in ABDTPA-P (3.5 mg kg-1), while medium in SO4-S (21.5 mg kg-1). Eight P and S treatments were involved in this study, i.e. single application of each 90 kg P2O5 (T1) and 20 kg S ha-1 (T2); integration of 90 kg P2O5 with S @ 20, 40 and 60 kg ha-1 (T3, T4 and T5, respectively), and integration of 120 kg P2O5 with S @ 20, 40 and 60 kg ha-1 (T6, T7 and T8, respectively). The experiment followed an RCBD arrangement that was replicated thrice. Recommended seed rate of maize (95 kg ha-1) was used for sowing. The results revealed that shoot biomass production was maximum when maize plants received higher doses of P and S in an integrated manner (120-60 kg P2O5-S ha-1). At 30 DAS, shoot fresh biomass was found maximum, and statistically alike, when 90 or 120 kg P2O5 was integrated with S @ 60 kg ha-1. Shoot fresh biomass was maximum, at 40 DAS when 120-60 kg P2O5-S ha-1 was applied to maize. Shoot dry biomass after 30 days of sowing was highest when 90 kg P2O5 was applied with S @ 60 kg ha-1 or when, 120 kg P2O5 was used with S @ 40 and 60 kg ha-1. Shoot length was maximum, both at 30 and 40 DAS, in case of using 120-60 kg P2O5-S ha-1. Chlorophyll content of maize was maximum, both at 30 and 40 DAS, when 90 kg P2O5 was applied with S @ 60 kg ha-1. Maximum fodder yield of maize was noted when 120 kg P2O5 was applied with 60 kg S ha-1. Highest P-uptake, both at 30 and 40 DAS was noted when 120 kg P2O5 was applied with S @ 60 kg ha-1. At the first stage of growth, S-uptake was highest when 60 kg S was integrated with 90 kg P2O5 ha-1. The study advocated integrated application of 120-60 kg P2O5-S ha-1 for obtaining economically maximum fodder yield of maize.","PeriodicalId":14298,"journal":{"name":"INTERNATIONAL JOURNAL OF PLANT AND ENVIRONMENT","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88333947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

L-tryptophan being an essential regulator with specialized activities in plant functioning, as well as an increase in tolerance to various abiotic stressors. A hydroponic experiment was carried out to determine the effective role of L-tryptophan in okra seedlings in saline environment in terms of growth, physiological, ionic, and antioxidant properties. Salinity was imposed in growth medium with two levels of NaCl (Control and 80 mM NaCl) whereas one level of L-tryptophan (50 µM L-1) administered externally in both combined and single forms. MDA and H2O2 contents increase while plant dry matter, chlorophyll content, relative water contents, membrane stability index, K+/Na+ ratio decreases due to salt stress. Salt toxicity was reduced when L-tryptophan was added as illustrated by increased relative water contents, membrane stability index, K+/Na+ ratio, as well as suppression of MDA and H2O2 generation. Our findings suggested that L-tryptophan increased salinity tolerance in okra, which could be a cause of viable sustainable production from salt-affected soils.","PeriodicalId":14298,"journal":{"name":"INTERNATIONAL JOURNAL OF PLANT AND ENVIRONMENT","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76078434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant growth produce is severely affected by various biotic and environmental and metabolic processes. Application of Potash fertilizer can reduce the harmful effects of saline stress and increase crop yield. This research was carried out to evaluate detrimental effects of salinity stress on wheat produce and to suggest appropriate dose of potash fertilizer to achieve optimum production under saline conditions. There were four K doses as (ck, 50, 3/4th and 100 kilogram K2O/ ha). The results depicted that potash fertilizer application increased wheat crop growth traits and produce substantially under saline regime, significantly. With potassium supplement, height of plant enhanced about 19.23 %, tillers per plant (36.24 %), length of spike (27.33 %) cm, wheat grains (23.5 %), and grain production increased (24.11 %) kg/ha. It was concluded that soil applied potassium fertilizer as K rate at 100 kg K2O yielded in maximum crop growth development and wheat produce at rate of 50 and 75 kg K2O ha-1. Therefore, potash fertilizer at rate of 100 kg K2O ha-1 may be adopted for optimum yield in wheat under saline environment.","PeriodicalId":14298,"journal":{"name":"INTERNATIONAL JOURNAL OF PLANT AND ENVIRONMENT","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83298454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
