It is worthwhile to mention that CA has got wider acceptance among researchers and farmers nowadays. A field experiment was conducted in an Inceptisol with three treatments, namely conventional tillage (CT), zero tillage (ZT) without residue and zero tillage with residue (ZT+R) in a maize (Zea mays L.)-wheat (Triticum aestivum L.) (M-W) and pigeon pea (Cajanus cajan L.)-wheat (P-W) cropping system at ICAR-Indian Agricultural Research Institute, New Delhi, with a view to characterize the HA by E4/E6 ratio and total acidity, and to specify the functional groups of clay humus complex. In ZT+R based treatments, lower E4/E6 ratio and total acidity of extracted HA showed higher degree of humification and stability of humic acid carbon (HA-C). The FTIR spectroscopy of the clay-humus complex (as extracted from soil) displayed the presence of a large number of functional groups in ZT+R treatment followed by ZT and CT. It was also observed that the yield of crops was also significantly higher in ZT+R than CT in both the cropping systems except in wheat crops in the M-W system. Therefore, it can be concluded that ZT+R has the potential to enrich the organic carbon (C) quality in soil and increase the aromaticity of HA, leading to carbon stabilization in soils.","PeriodicalId":13499,"journal":{"name":"Indian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134960583","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}

The grain number and associated 10 characteristics' coefficient of phenotypic variability was substantial, with the grain number per panicle having the greatest PCV and GCV. Principal component analysis was used to further identify the relationships and trends among the RILs. The first four primary components (74.58%) fully described the variability of all 10 features. Cultivars were divided into 8 groups based on the characters used to attribute grain number. To analyse genetic differences between RILs at the molecular level, 22 SSR markers were utilised and the PIC value was 0.709. A strong and significant relationship between them was shown by the structural analysis, with spikelet number and spikelet fertility per cent indicating a particularly strong correlation.

Genetically pure seeds were used and stored in cloth and polythene bags. Seed quality parameters (germination, seedling length, seedling dry weight, and seed vigour) were monitored at various intervals (0, 3, 6, 9, 12, 15, 18 months). Freshly harvested seeds (control) exhibited superior quality, with higher germination rates, longer seedlings, greater seedling dry weight, and improved vigour indices compared to stored seeds over 18 months. Seed quality deteriorated with longer storage, reaching its lowest point at 18 months. Among storage containers, cloth bags showed a faster decline in seed quality compared to polythene bags (>700 gauge). In field experiments, one-year stored seeds from polythene bags outperformed those from cloth bags in terms of seed establishment percentage, mean emergence time, and germination speed. In conclusion, polythene bags maintained acceptable seed germination (meeting IMSCS standards) for up to 15 months, while cloth bags maintained it for up to 12 months. Therefore, polythene bags are a better choice for preserving eggplant seed quality during storage, particularly for longer durations.","PeriodicalId":13499,"journal":{"name":"Indian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134960791","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}

After 15 days of inoculation, several measurements of the lengths roots, stem and leaves were noted and symptoms of Fusarium disease were also recorded. The results revealed that F. oxysporum is a pathogen for tomato (Solanum lycopersicum L.) plants (super strain) variety, causing Fusarium disease of this host, which manifests by yellowing, wilting and necrosis of aerial parts, and reduced growth parameters in plants. Therefore, the disease incidence after 15 days of inoculation is estimated at 75 and 50% for (T1 and T3) respectively. In addition, our results revealed that the percentage of incidence was 100 and 25% respectively for T1 and T3 after 22 days. Whereas, the results showed that mycorhizal fungi are associated with the roots of tomato plants. They reduced the incidence rate of Fusarium disease by 50% (T3) and improved the growth of tomato seedlings (Super strain) which manifests itself by a vigorous root system and a very important development of the aerial parts. These results indicate that arbuscular mycorhizal fungi can effectively contribute to the ecological management of soil-borne fungal disease.","PeriodicalId":13499,"journal":{"name":"Indian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134960780","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}

CMS lines showed varying responses to distinct genetic backgrounds. Per cent siliquae set and seed set per siliquae changed due to cytoplasmic-nuclear interaction. Studies on stigma receptivity evaluation using manual pollination up to 7 days since anthesis revealed that it varies among the 3 CMS sources of Brassica juncea. Peak stigma receptivity reached up to 2 to 3 days following flower opening. Among the 3 CMS sources berthautii showed higher stigma receptivity compared to Moricandia and erucoides. Among the nuclear genotypes, Pusa Tarak was the most promising. The new CMS sources would be useful for hybrid development based on higher stigma receptivity for hybrid seed production.

Wheat productivity matched in both zones; yet the level of yield-sustainability was much less in warmer climate of CZ. Yield sustainability was poorest in late-sown wheat of CZ and the drop in sustainability index (SI) was realized in locations, years and genotypes. For grain yield; locations and location-year interaction mattered most in each production environments but the years were crucial only in NWPZ-TS. Results showed that yield sustainability of test sites can not be adjudged by its productivity alone. Location status was associated with the yield sustainability only in NWPZ. Substantial drop in sustainability could be noticed in some crop seasons of CZ but deviations in NWPZ were smaller. In test sites, the causative factors associated with yield-sustainability varied under different production environments. Genotype-year interaction was effective in each situation except CZ-LS where only the crop year variations were supreme.
