Two multi-year lysimeter experiments at Sakha Agricultural Research Station, Kafr El Sheikh, Egypt, were conducted to investigate the impact of soil organic substances and foliar application of nano-Silica on physico-chemical soil properties and yield of wheat in salt affected soils (2017/18 and 2018/19 winter seasons). The experiment was executed in split plot with three replicates having organic substances (Molas (M),Compost tea (CT), K-humate (KH), M+CT, M+KH, CT + KH, M+CT+KH and control treatment in main plots while sub plots had foliar application of (tab water and nano-Silica).The results showed that physico-chemical properties (bulk density, porosity , cation exchange capacity, electrical conductivity, exchangeable sodium percentage etc.) and fertility (availability of Nitrogen, Phosphorus and Potassium ) of the soil were significantly influenced by all organic substances, however co-application of molas+K-humate+compost tea remained unmatched. The same treatment combination also remained effective in boosting Nitrogen and protein in grain along with wheat yield during both seasons. With foliage applied nano Silica remained superior by recording the highest yield attributes and grain yield of wheat. Therefore, it is inferred that co-application of organic substances and foliage applied of nano-Silica could be developed as an effective approach to restore and conserve the soil and increase wheat productivity in salt affected soils environment arid and semi-arid regions.","PeriodicalId":14335,"journal":{"name":"International Journal of Plant & Soil Science","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85931485","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}

The present research was carried out to induce mutants in kodo millet variety CO 3 using a physical mutagen (gamma rays) and a chemical mutagen (Ethyl Methane Sulphonate) for creating novelty. Seeds were treated with five doses of gamma-rays viz., 100 Gy, 200 Gy, 300 Gy, 400 Gy, and 500 Gy at BARC, Kalpakam and with three concentrations of EMS viz., 24.15 mM, 32.20 mM and 40.25 mM. In the laboratory test, root and shoot lengths of seedlings were decreased with an increase in the dose of gamma rays and EMS. In field study, the germination percentage and survival rate of seedlings were decreased with an increase in the dose of gamma irradiation and EMS. In M2 generation, five types of chlorophyll mutations viz., albino, xantha, striata, chlorina and albomaculata were observed. Xantha and chlorina were observed in all treatments, whereas, striata and albomaculata were observed only in 200 Gy. Based on the biological damages on M2 plants, mutagenic effectiveness and efficiency were estimated. Both mutagenic effectiveness and efficiency reduced with the increase in the dose of irradiation. Regarding height reduction and lethality, the dose of 100 Gy in gamma treatment and 32.20 mM concentration in EMS treatment recorded maximum efficiency. The mutagenic effectiveness was found to be higher at gamma rays irradiated with 100 Gy and in EMS, in 24.15 mM concentration. The 100 Gray dose and 24.15 mM concentration was found to be highly effective for inducing mutation in kodo millet.","PeriodicalId":14335,"journal":{"name":"International Journal of Plant & Soil Science","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79611855","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}

Main plot treatments comprised three mango varieties (Bire, Tommy Atkins, Zillate), while sub-plot treatments comprised four concentrations of KNO3 (zero as control, 1, 2 and 4%). Data was collected on number of terminal buds induced after applying KNO3, percentage flowering, number of fruits set per 20 panicles and fruit yield per tree. \u0000Results: Trees sprayed with KNO3 produced higher (P < .05) numbers of terminal buds than the control. Across sites, Bire produced higher numbers of buds (64.8) than Tommy Atkins (46.3) and Zillate (17.8). Flowering response was higher in Bire (28.6%) than in Tommy Atkins (20.8%) and Zillate (17.8%). Flowering response of trees sprayed with 2% KNO3 (31.4%) was higher than that of trees sprayed with 1% KNO3 (24.7%). Mean number of fruits induced per 20 panicles in trees sprayed with 4% KNO3 (8.24) was higher than that of trees sprayed with 1% KNO3 (4.8). Fruit yield of Tommy Atkins (23.01 kg/tree) was higher than that of Bire (10.97 kg/tree). Mean fruit yield of trees sprayed with 2% KNO3 (27.36 kg/tree) was higher than that of trees sprayed with 1% KNO3 (15.93 kg/tree). \u0000Conclusion: For better fruit yields, farmers at Bulindi should grow Tommy Atkins and apply 2% KNO3.

The biggest challenge is to attain food security in the ever increasing growing population. Rice (Oryza sativa L.) is a staple food crop for half of the world's population and one of the world's most significant food crops. Farmers must produce more rice with enhanced quality in order to ensure food security in rice-consuming countries across the world. Rice (Oryza sativa L.) is considered to be a Si accumulator plant and tends to actively accumulate Si into tissue up to concentrations of 5% or even higher. The present study aimed to use different forms of N and Si sources at different levels to improve the growth traits contributing to the increase yield of rice. A pot experiment was conducted in glasshouse, TNAU, Coimbatore to assess the response of nitrogen and silica on paddy during October 2020 – January, 2021. The treatments comprised of the two factors, nitrogen and silica with three replications. The growth parameters like plant height, number of tillers per plant and total dry matter production were recorded at all stages and yield traits at harvest stage. The treatment, T11 - N2S2 (53.4 and 110.2 g pot-1 respectively) significantly enhanced the grain yield (34%) and straw yield (40%) than control in the pot experiment. Highest growth and yield parameters were recorded with application of combined fertilization of nitrogen and silica (T11-N2S2) which comprises150 kg ha-1of urea and 200 kg ha-1 of calcium silicate compared to control.","PeriodicalId":14335,"journal":{"name":"International Journal of Plant & Soil Science","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83637599","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}
