Effects of vermicompost and urea on the seed germination and growth parameters of Vigna mungo L. and Vigna radiata L. Wilzek

Abstract

Growth attributes of Vigna mungo and Vigna radiata crop influenced by level and type of fertilizers. The present study was carried out to evaluate and compare the effects of organic (vermicompost) and inorganic (urea) fertilizers on the germination percentage and seedling growth of V. radiata (Green gram) and V. mungo (Black gram). Fresh weight and dry weight of tested plant samples at 10th days of growth stage were also determined. Vermicompost was used as organic fertilizer and urea as inorganic fertilizer. Experimental results showed that vermicompost and urea both has positive effect on seedling growth parameters of V. mungo and V. radiata [average root length (6.1cm and 6.7cm)] , shoot length (6.5cm and 8.3cm), leaf area (312.2 sq.cm and 334.1 sq.cm] as compared to control set [average root length (4.4cm and 4.3cm)] , shoot length (6cm and 5.9cm), leaf area (282.7 sq.cm and 305.5 sq.cm). But urea exerts negative effect on seed germination percentage in V. mungo and V. radiata (58% and 50%) as compared to control (77%). Vermicompost exhibited better result in above parameters in comparison to urea. V. mungo showed increased value in comparison considering V. radiata in case of organic, inorganic fertilizer treated as well as control sets. As composition of locally available fertilizers is unknown, the application of these fertilizers for improving germination percentage and growth parameters of tested crop need to be evaluated. Present work may provide the suggestive approach for usage of these tested fertilizers in field level trial.

Effect of Integrated Nutrient Management on Growth and Yield of Irrigated Blackgram (Vigna mungo L.)

“…The favourable effect of vermicompost and RDF resulted in a significant improvement in yield attributes and an unexpected increase in seed and stover yield of blackgram. These findings agree with those of Bakthavathsalam and Deivanayaki [11], Geetha and Velayutham [12], Bhattacharya et al [13], and Hussain et al [14]. Shashi Kumar et al [15].…”

Assessing the influence of integrated nutrient management on growth and yield of Black gram (Vigna mungo L.)

“…While, the lowest stem dry weight plant -1 (1.19 g) was found in no application of manures and fertilizer. Likewise, Bhattacharya et al (2019) and Zannat et al (2020) also found parallel result in respect of dry weight which confirms the present findings. Root dry weight plant -1 (g) differed insignificantly with organic and inorganic fertilizer doses at 40 and 50 DAS (Figure 1F).…”

“…weight of black gram as well as a significant improvement in yield parameters (Bhattacharya et al, 2019).…”

“…Vermicompost also contains microsites which are rich in carbon and nitrogen, and it also improves solubility of other nutrients (Parthasakthi et al, 2008, Haridha et al, 2020. Consequently, use of combined inorganic and organic fertilizer are found to be more effective in improving productivity in several crops (Mainul et al, 2014, Bhattacharya et al, 2019, Hossain et al, 2017, Uddin et al, 2022. Subsequently, black gram crop plants will produce more yield when the proper amount of chemical fertilizers is combined with cowdung, poultry manure and or vermicompost.…”
