The effect of vermicompost application on the growth of lettuce plant (Lactuca sativa L.)

Abstract

The application of salt fertilizer to increase the productivity of lettuce in long term application will decline soil fertility. Implementation of totally organic farming in some region cannot increase productivity rapidly. The application of vermicompost combined with inorganic fertilizer is a solution to overcome decline lettuce production on the first time implementation of the organic farming system. This research aims to study the dose application of vermicompost on the growth of lettuce plant. The research conducted at Cisurupan-Garut West Java Province with altitude 1183 m above sea level from January to March 2018. The method used in this research is randomize block design with seven treatments (A = without vermicompost, B = 5, C = 10, D = 15, E = 20, F = 25, G = 30 t ha-1), and four replication. The growth parameter observed in this research was plant height, number of leaves, fresh plant weight, plant dry weight, and shoot-root ratio. The data observation parameter than analysed with variance analyse at five per cent signification level. The result of this research shows that the application of 5 t ha−1 vermicompost improves plant growth significantly.

Effect of organic and biostimulants on Yield and quality of evening primrose oil (Oenothera biennis L.)

“…This has a favorable impact on the production of chlorophyll, vegetative development, and crop quantity. These outcomes align with the ones obtained by Arancon and Edwards (2005); Tejada et al (2006) and Frasetya et al (2019).…”

“…Furthermore, an increase in chlorophyll content increases the efficiency of the photosynthesis process. These results confirm those obtained by Frasetya et al, 2019. It is already known that applying seaweed extract exogenously can improve plant development, stimulate the production of chlorophylls, and increase the uptake of N, P, K, Mg, Ca, Zn, Fe and Cu by plants (Mahdy et al, 2022).…”

Enhanced leachate phytodetoxification test combined with plants and rhizobacteria bioaugmentation

“…Then, plants were watered with 2 L of leachate every 3 days. Physical observations were carried out daily by measuring plant height in aerial plants which was then made a growth rate graph to determine the different effects on each concentration [ 46 ]. The time of the RFT test was 4 days/96 h, however, if there was no change in conditions, it was extended by 24 h to 14 days.…”

Respons Pertumbuhan Tanaman Kelapa (Cocos nucifera L.) Belum Menghasilkan terhadap Aplikasi Berbagai Dosis Kascing

“…Hasil penelitian Ceritoglu et al (2018) menunjukkan bahwa vermikompos, memberikan banyak manfaat secara langsung maupun tidak langsung bagi pertumbuhan tanaman dan kualitas produk. Hasil penelitian Frasetya et al (2019) menunjukkan bahwa aplikasi kompos vermikompos 5 t/ ha dapat meningkatkan pertumbuhan tanaman lettuce (Lactuca sativa L.) secara signifikan. Hasil penelitian Aritonang dan Sidauruk (2020) pada tanaman buncis Hasil penelitian menunjukkan bahwa dosis 60 g,90g dan 120 g vermikompos berpengaruh nyata terhadap jumlah cabang, jumlah polong dan bobot biji kedelai (Glycine max L.).…”
