Augmentation of yield in African marigold (Tagetus erecta L) through Path co efficient analysis and correlation studies

Paper ID- AMA-26-11-2022-11842

Path co efficient analysis and Correlation studies were carried out in 35 genotypes of African marigold and correlation co efficient for different characters at genotypic and phenotypic levels are presented. In general, genotypic correlations were larger magnitude than that of corresponding phenotypic correlation indicating the, strong association between the traits studied. The knowledge of correlation helps in determining the relative importance of component characters influencing the yield. The branches per plant, significantly positive correlation was observed between flower yield per plant and stalk length. Days to first flowering were the only character their exhibited a non-significant and positive association with flower yield per plant. Hence an idotypic of African marigold should be tall in stature, bearing more branches, producing maximum number of flowers in order to get high yield and to realize maximum return for the flower growers.

Histological and hormonal changes in the compatible rootstock-scion in Solanum species

Paper ID- AMA-24-11-2022-11838

Flooding is a severe constraint to tomato growth and productivity in many regions. Grafting is a favourable technique to overcome this constraint and a study was conducted to comprehend the histological implications influenced by hormones in the compatible root stock-scion of Solanum species. The scion used for the study was tomato cv. PKM 1 and the different selected flood tolerant Solanumroot stocks, based on the previous studies were Solanum lycopersicum(LE 523, LE 828, LE 102), Solanum torvum, Solanum aculeatissimum and Solanum sysimbriifolium.The compatibility of root stock and scions were evaluated by graft success per cent and microtome studies. Significant differences were observed in graft success per cent among the different tomato grafts. Among the six root stocks and scion combination, Solanum torvum * PKM 1 recorded significantly higher graft success per cent (95%) followed by Solanum sisymbriifolium * PKM 1 (69.40 %), whereas in LE 102* PKM 1 and LE 523* PKM 1grafts, it was 9.34% and 13.3% explicating the graft incompatibility. At the initial stages of observation, control (PKM 1) which is the non-grafted plant manifested better growth than the tomato grafts (30 DAG). The histological studies revealed that the vascular connection was developed earlier in LE 828 * PKM 1 graft compared to Solanum torvum * PKM 1. From this study, it was concluded that LE 828 root stock demonstrated earlier formation of vascular connection and vigorous root growth that enhanced water and nutrient uptake resulting in better growth. Other tomato grafts where the root stocks were Solanum torvum, Solanum aculeatissimum, Solanum sisymbriifolium, though compatible with PKM-1, the vascular connection was delayed. These compatible root stocks might be further studied for its tolerance to survive abiotic and biotic stress in comparison with LE 828 root stock for further validation of superior compatible root stock.

Effect of foliar application of zinc and boron on leaf nutrient status of lemon (Citrus limon Burm.) cv. Pant Lemon-1

Paper ID- AMA-23-11-2022-11836

The present study was carried out at Horticulture Research Centre, Patharchatta, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar to study the Effect of foliar application of zinc and boron on leaf nutrient status of lemon (Citrus limon Burm.) cv. Pant Lemon-1. The experiment was conducted in a Randomized Block Design with sixteen treatments and three replications during 2019-20. The soil of experimental site was sandy loam having pH 7.51 and EC 0.67 (dS m-1). Treatments, having different concentrations of zinc and boron (0.2%, 0.4% and 0.6% each) alone and in combination, were applied by the foliar spray method before flowering twicely in the month of April and May. Foliar application of Zn significantly increased the Zn concentration in leaves but it showed antagonism with the P and Mn concentrations. The treatment T10 (0.4% ZnSO4 + 0.2% H3BO3) showed the maximum increase in Zn concentration (33.30 ppm) while in the treatment T3 (0.6% ZnSO4) the concentration of P was decreased maximally by 0.02% and also a maximum decrease of 18.94 ppm in Mn concentration then their initial values. The maximum increase in boron concentration (16.91 ppm) was observed in the treatment T10 (0.4% zinc sulphate + 0.2% boric acid), but no regular pattern was observed with other nutrients like N, K, Fe, Ca and Mg. Therefore, it is suggested that for obtaining maximum yield and good quality fruits of lemon, foliar application of 0.4% zinc sulphate and 0.2% boric acid twice at one month interval in mid April and mid May before flowering was feasible.

Magnitude of genetic variability is important for any breeding programme for the selection of suitable genotypes and heritable characteristics of the plants. The present experiment was conducted during 2018 to identify the suitable selection criteria and identification of the genotype(s) suitable for the experimental area. Randomized block design with three replications was followed for evaluation of sixteen genotypes of okra. Study revealed that the maximum values were recorded for number of leaves (9.37), plant height (30.40cm), stem diameter (0.71cm), number of flowers (12.33), branches (7.33), number of fruits (6.74), TSS (7.30 OB), fruit length (11.43cm), fruit girth (1.26cm), fruit weight (16.22g), fruit yield (72.56g/plant, 2.96kg/plot, 108.41q/ha), acidity (0.73%), vitamin C (11.85mg/100g) and fruit moisture (84.29%) as desirable characters for crop evaluation in okra. Based on overall performance, 16 genotypes were grouped in to three clusters and cultivar Arka Anamika was marked as the best performer which could be beneficial for further crop improvement programme and most suited to Lucknow subtropical condition.

17 genotypes of Chakhao (black rice) varieties which are found locally in Manipur were evaluated under experimental rice field at Mongsangei, near SSB, Imphal west during two consecutive Kharif seasons of 2019 and 2020. Data were recorded on thirteen quantitative characters and the analysis of variance revealed highly significant for all the traits in both the year and on data pooled over years, indicating the presence of considerable amount of variability among the genotypes. High estimates of GCV and PCV was observed for number of effective tillers per plant, highlighting the presence of wider variability for this character as compared to other characters. High heritability along with high genetic advance were observed for grain yield per plant, number of spikelets per panicle and number of filled spikelets per panicle. Correlation studies showed that Grain yield per plant exhibited significant positive correlation with the characters tillers per plant and effective tillers per plant at both genotypic and phenotypic level. And at the phenotypic level for the characters plant height, number of spikelets per panicle and number of filled spikelets per panicle. For path analysis, the highest direct effect was exhibited by no. of effective tillers per plant followed by no. of days to 50% flowering, no. of filled spikelets per panicle, flag leaf length and plant height in both genotypic and phenotypic level. Highest indirect positive effect was revealed by no. of tillers per plant through no. of effective tillers per plant. Also panicle length, plant height, no. of spikelets per panicle, no. of filled spikelets per panicle and no. of tillers per plant showed high indirect effect through no. of effective tillers per plant in both genotypic and phenotypic level. The study concluded that, Chakhao Poireiton A can be used as a promising genotype since it exhibited high grain yield per plant, high no. of spikelets per panicle, and highest no. of effective tillers per plant.
