Allelopathic Effect of Root and Leaf Lechates of Selected Tree Species on the Growth of Pulses | Chapter 6 | Current Research Progress in Agricultural Sciences Vol. 9

The present experiment was carried out study the effect of teak, eucalyptus and casuarina tree leaf and root leachates on the growth of green gram, black gram, chickpea and cowpea. Results were affected significantly by tested parameters. There were both stimulatory and inhibitory effects were seen on the crop growth by the tree leachates. The inhibitory effect of leachates was greater during the early stages of crop growth (15 DAS) and in later stages, the effect was reduced. And some of the parameters show stimulatory effects at later stages.

Analysis of Genetic and Molecular Diversity in Green Gram (Vigna radiata (L.) Wilczek) Genotypes Using SSR Markers | Chapter 1 | Innovations in Biological Science Vol. 5

 

Mungbean, often known as Greengram, is a member of the Leguminosae family. A study on the genetic and molecular diversity of 40 genotypes of Greengram was conducted using SSR markers. The study of molecular markers is essential to genomic research. Because of their repeatability, multiallelic nature, codominant inheritance, relative abundance, and good genomic coverage, SSRs stand out among other marker systems like restriction fragment length polymorphism (RFLP), RAPD, sequence tagged sites (STSs), and AFLP. The experimental material contained significant genetic diversity; nevertheless, for all yield-related and yield-attributing features, phenotypic coefficient of variation exceeded genotypic coefficient of variation. The genotypes LGG 574 (8.80), PDM 139 (8.34), and Pant Mung 6 had the highest seed yields (7.78). The highest observed cluster distances were between clusters 5 and 6 (472.88) and clusters 4 and 5 (432.89). Among all the factors PC 1 to PC 10, PC 1 (19.99) accounted maximum proportion of variability in the set of all variables and the remaining components accounted for progressively lesser and lesser amounts of variation. The first six principal components (PC-1 to PC-6) with eigenvalues of 2.94, 2.62, 2.18, 1.40, 1.28, and 0.86, respectively, accounted for 86.95% of the total variance for all the qualities, according to principal component analysis. Genotypes 23, 32, 33, and 21 were spread out relatively far from other genotypes in the scatter plot, suggesting that they might be different from other genotypes. PIC values of 10 SSR loci, where the VR 86 marker produced the greatest PIC Value percentage and highest heterozygosity percent. The fixation index ranges from 1.000 to -0.076. In comparison to Cluster II, III, IV, and V, Cluster I has the most genotypes (25), and the use of SSR markers in this work to differentiate between genotypes was made possible by the high polymorphism information richness of this cluster. This study shows that SSR analysis can be used to evaluate the molecular diversity of various Greengram genotypes. For the purpose of marker-assisted breeding programmes, plant breeders highly value the information generated on marker data.

Greengram Growth and Yield under the Rice-Pulses Cropping System: Residual Effects of Various Vermicomposts | Chapter 2 | Emerging Issues in Agricultural Sciences Vol. 4

 The present study was proposed to investigated the leftover effect of various types of vermicomposts on greengram growth and yield under edible grain-pulses cropping plan. Vermicompost is an utilizable basic source which is capably used for one plants due to allure mucous covering in vermicast and slow release of the nutrients. Vermicompost use is more economical than artificial organic manure. So, economic being, environmental stability, and improving livelihood status are the major causes for allure worldwide adoption in snack production.The study design secondhand in the field experiment was randomized complete block design accompanying 11 treatments and 3 replications. The experiment was conducted all the while the year 2021after the harvest of edible grain.The various types of vermicomposts were used to the previous crop rice as basic application. The greengram was planted after the harvest of edible grain with the handy moisture and residual vitamins present in the field. The green grandam variety mature was CO 8 with the duration of 60 days. The sources were sown at the organize of 30cm x 10cm in between the rows of edible grain stalks in the plot. The observations were made for the tumor and yield parameters like plant altitude (cm), drymatter production (kg ha-1), number of pods plant-1 and the beginning and haulm yield.Among the various vermicomopsts applied, the vermicompost adapted from the coconut wastes doctored with Eudrillus eugeniae (T2) acted well and residual nutrients were efficiently utilised by the greengram crop and the progress and yield were higher in this place treatment. The slightest growth and yield of greengram was found in the situation Eisenia foetida treated accompanying farmwastes (T9) which was attended by control as the treatment was without use of any vermicomposts.It maybe concluded that vermciomposts willing from earthworm species Eudrillus eugeniae with head wastes have higher leftover nutrients and it maybe suggested to the farmers to produce and take advantage of this type of vermicompost.
