The TC, SOC and TOC stocks followed the order: AFS > F-F > FL in various soil depths. The active carbon (AC) pools (VLC + LC) were higher in 10-year plantation cycle (62.3% of TOC) than 30-year cycle (32.9% of TOC), whereas the passive carbon (PC) pools (LLC + RC) were higher in 30-year plantation cycle (67.1%) than in 10 years (37.7%) in surface depth. The contribution of LLC to PC was higher in 30-year plantation cycle (65%) than in 10-year plantation cycle (48%).

Among the treatments, LP+LF+X+C additive treated silage had minimum dry matter loss throughout ensiling period. There was no significant difference in pH between LP+LF+X+C and LP+LF+X treated silage, but numerically pH value was lower in LP+LF+X+C treated silage. Lactic acid content significantly declined as ensiling period progresses but there was no significant difference among LP+LF+X+C, LP+LF+X treated silage and 15th, 25th days of ensiling. Lactic acid to acetic acid ratio was significantly improved in LP+LF+X+C treated silage as compared to other treatment combinations. The microbial count of silage was increased up to the 15th day of ensiling.

In general, dry matter was higher in north Indian ecotypes, while CP was more in south Indian ecotypes (28.70%). South Indian ecotypes had low concentration of fibre and as a result found best for fodder quality traits. Dry matter intake, digestible dry matter, total digestible nutrients, and relative feed value were maximum in tender leaves due to comparative low amount of NDF and ADF in tender leaves.

Analysis of variance for all traits under study showed sufficient amount of genetic variability, which revealed that all genotypes significantly different from each other. Three principal component analyses had Eigen values more than one and explained about 65.77% of the total variation. The first principal component explained about 35.56% of total variation followed by second (18.01%) and third (12.20%) principal components. Clustering analysis based on various morphological traits assorted 28 genotypes into five clusters. Cluster I had the highest number of genotypes (23) followed by cluster III which consists of two genotypes. The clusters II, IV and V contained only single genotype each. Data frequency distribution using box plot analysis for green fodder yield and its attributing traits revealed that huge amount of variation was present in exotic germplasm accessions under study. Further testing of these exotic germplasm accessions for fodder traits will be very useful in future breeding programmes to enhance fodder yield in oat.","PeriodicalId":49636,"journal":{"name":"Range Management and Agroforestry","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135842779","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}
