The experiment was laid-out in split-plot design which includes three irrigation scheduling in main plots and four residue mulch practices in sub plots. Soil temperature at 15 cm enhanced by 0.6-9.8 0C under mulch and by 0.7-1.2 0C with irrigation at 20% DASM over other irrigation levels. Mulch significantly decreased bulk density by 1.43-3.59% while increased saturated hydraulic conductivity by 3.8-41.0% and mean weight diameter by 6.0-20.0%. Irrigation at less depletion of available soil moisture favoured soil physical properties. Mulch and increase in irrigation frequency tended to increase in relative water content and transpiration rate while decreased leaf diffusive resistance. No noticeable differences in leaf temperature were observed under mulch and irrigation. Green gram straw mulch and irrigation given at 20% DASM produced 2.6-14.2 % and 1.3-9.2% higher grain yield, respectively.

The applied citric acid was found to be significantly superior in decreasing the Al and Fe bound P, whereas, oxalic acid was superior to citric acid in reducing the Ca bound P. Application of 20 mg LMWOAs kg-1 was found to be better dose in enhancing the available P and reducing the Al, Fe and Ca bound P. The applied 100% recommended dose of phosphorus showed significant increase in available, calcium, aluminium and reductant P fractions over other levels of applied P. The application of LMWOAs significantly enhanced the P content in both wheat and soybean crops.

The controlled release/ slow-release N fertilizers are smart choices to serve this purpose. So, this manuscript aims to synthesise nano clay bio-polymer composites (NCBPC) and using it for controlled N release. Nano clay bio-polymer composites were prepared by aqueous copolymerization of acrylic acid with acrylamide in presence of bentonite nano clay and starch as a partial replacement for synthetic polymers. Maize and wheat flour (maida) were used as starch source at 20 and 30% replacement level to synthesise different NCBPC products. The resulting products were characterized using FTIR and SEM which revealed the participation of bentonite and starch in the polymerization reaction at the nano level. The incubation study in soil disclosed the slow-release of nitrogen by these materials. Therefore, bentonite clay with cereal grain flours may be used for the synthesis of nano clay bio-polymer composites for slow-release of nitrogen.","PeriodicalId":8031,"journal":{"name":"Annals of Plant and Soil Research","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83520688","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}

In this study Black guava is characterized morphologically, biochemically and on molecular basis. Result revealed that Black guava had the maximum total anthocyan in content (9.663 mg/100g) compared to white and pink pulped counterparts. Pink pulped Hisar Surkha and Lalit genotypes contained both lycopene and anthocyanin while another pink pulped genotype, Punjab Pink, had only lycopene. Further, all the eight guava genotypes irrespective of their pulp colour had total carotenoids (0.203 mg/100g - 0.730 mg/100g). Based on our results, the Black guava had unique morphological features like leaf colour, shoot colour and fruit pulp colour. The pulp colour of Black guava is due to the presence of anthocyanins. In general, the pulp colour of guava is due to combinations of more than one pigment and the final colour depends on the relative proportion of those pigments and suggests that “pigments in proportions” explains the pulp colour in guava. Anthocyanin pathway study in Black guava revealed that the primers for DFR and CHS gene of anthocyanin pathway amplified in Punjab Pink and not in case of Black guava.","PeriodicalId":8031,"journal":{"name":"Annals of Plant and Soil Research","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89101012","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 principal components PC1, PC2 and PC3 contributed about 37.44%, 22.63% and 13.28%, respectively to the total variation. The first principal component exhibited high positive loading for grain yield, stover yield, plant height, spike length, spike thickness and 1000-grain weight which contributed more to the diversity. The second principal component showed high loading for days to 50% flowering, days to maturity and 1000-grain weight. Cluster analysis grouped the genotypes into five clusters indicated that grain yield, stover yield, 1000-grain weight and days to maturity contributed maximum towards genetic divergence. The grouping patterns of genotypes in principal component analysis and cluster analysis were almost in agreement with each other with minor deviations.
