In the present investigation an attempt has been made to study the genetic variability present in root system architecture of tomato genotypes at vegetative stages. Fifteen tomato genotypes were evaluated in CRD with three replications at AICRP on Vegetable Crops, OUAT, Bhubaneswar during the year 2020-21. Three seedlings per pot were grown and observations were recorded on thirteen RSA traits. Analysis of variance indicated presence of significant differences among the tested genotypes in respect of different RSA traits. Number of root crossings showed the highest GCV (59.35). Broad sense heritability was the highest (97.56 %) in case of volume of fine roots. The results of D 2 analysis revealed 4 numbers of clusters. Results on principal component analysis revealed that PC1 and PC2 had 65.32 % and 26.33 % of contribution towards total variability.","PeriodicalId":15551,"journal":{"name":"Journal of Crop and Weed","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82199662","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 split-plot design was laid out with tillage as the main plot and nutrient management practice as sub-plot with 3 replications.

Similarly, higher chlorophyll content and nutrient content was also noticed with an interaction effect of PB and 60% RDN+GSGN.

An improvement is essential to enhance their production and productivity. Crop improvement in this solanaceous vegetable depends on the magnitude of genetic variability, heritability, and genetic advancement. Thus our study examined genetic variability, heritability, correlation, and path coefficients of 46 advanced tomato lines to determine the association between yield and morphological traits. Most of the traits studied under this experiment had higher phenotypic coefficient values than genotypic coefficient values, indicating the expression of environmental influences. Among nine different characters studied, the fruit number plant -1 showed high variability, heritability, genetic advance, correlation and path coefficient values with the highest yield plant -1 . A greater dissimilarity coefficient value is associated with higher heterosis. In breeding programs, lines showing a higher dissimilarity coefficient value should be considered. Tomato genotypes BT-215-3-3-1 and BT-2 selected based on the fruit number plant -1 may be used for the future hybridization program.","PeriodicalId":15551,"journal":{"name":"Journal of Crop and Weed","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83864937","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 crop is normally planted at a distance of 90 cm x 90 cm and the crop takes about 3-4 months for proper establishment of the canopy after sprouting . Field experiments were conducted at five locations of different agro ecological conditions of India during 2015-16 and 2016-17 to assess the production potential and profitability of different greater yam based intercropping systems, to make use of the spatial and temporal availability of resources during the initial establishment period. Field corn (Zea mays L.), sorghum [Sorghum bicolor (L.) Moench] and pigeon pea [Cajanus cajan (L.) Millsp.] were intercropped with yam in 1:2 ratio at a spacing of 60 × 30 cm and trailing yam vines on intercrops. Pooled data analysis indicated that the maximum yam-equivalent yield (26.05 tha -1 ), land-equivalent ratio (1.46), net income (3,59,146/-) and B:C ratio (4.12) were obtained with greater yam + maize intercropping in all the locations. Intercropping could result in 31.5% land saving, comparable yam equivalent yields and up to 49% increase in net income compared to sole crop. Hence maize which is a starch rich crop can be profitably inter cropped with greater yam which is another food and nutrition security crop without sacrificing the main crop stand and yield. Maize stalks after harvests of cobs can act as stakes for yam vines also.","PeriodicalId":15551,"journal":{"name":"Journal of Crop and Weed","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88923357","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 experiment used a split plot design with the micropot technique as the first component, seven priming treatments (Hydro priming, Solid matrix priming, Osmotic priming, Halo priming, Hormonal priming, Vermi priming, Bio priming) along with control as the second factor, and three replications. Seed priming was employed as a subplot treatment, while the micropot method was used as the main plot treatment. Days to 50% flowering, basal girth (cm), number of leaves plant -1 , plant height (cm), days to maturity, head diameter (cm), number of seeds head -1 , seed setting percent, seed length (mm), seed breadth (mm), 100 seed weight (g), hulling percent, seed yield plant -1 (g) were all measured according to standard procedure. Some seed quality parameters like germination percentage (%), seedling length (cm), seedling dry weight (mg seedling -1 ) and vigour index were studied to judge the seed quality parameters of harvested seeds. Considering various morphological characters, T 4 (Halo priming) followed by T 7 (Bio priming) was earliest to 50% flowering (63.8 and 64.0 days respectively). T 4 (Halo priming) recorded earliest days to maturity (119.2 days) and it was followed by T 8 (control) with 121.1 days. Maximum seed yield plant -1 (75.6 g) was noted in T 6 treatment followed by T 7 treatment (73.6 g) due to larger head, more number of seeds head -1 , maximum seed setting percentage, seed length, seed breadth and maximum 100 seed weight. Germination percentage was highest (88.79 %) in T 3 (Osmotic priming) due to better filling of seeds. Maximum seedling length (17.57 cm) and vigour index-I (1522.54) was recorded in T 6 (Vermi priming) treatment. The performance of crop for different morphological and yield contributing characters was better in micropot techniques than without micropot techniques. Therefore, vermi priming and bio priming along with micropot techniques are potentially able to promote rapid and uniform plant growth, thereby improving the yield and seed quality of sunflower.","PeriodicalId":15551,"journal":{"name":"Journal of Crop and Weed","volume":"102 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89927676","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}
