Quality of Growth Media and Yields of Allium ascolanicum L. on Ultisol Soil Combined with Rabbit Manure

Abstract

Onion cultivation in pots is a solution of limited land in urban areas. Nevertheless, the onion productivity is constrained by the quality of planting media. The utilization of rabbit manure is an alternative to improve the quality of planting media. This study was aimed to determine the effect of rabbit manure level in the planting media on the growth and yield of onion, as well as the effect of rabbit manure on planting media quality. The method used was a completely randomized design with one factor and 12 replications. The treatment was rabbit manure level on growth media i.e. 0%; 25%; 50%; 75%; and 100%. Parameters measured were leaf lenght, number of leafss, diameter and weight of bulbs, pH of planting media, Cation exchange capacity (CEC), Sodium, Phosphor and Potassium. The results showed that 25%-50% rabbit manure in planting media produced the best on leaf lenght, number of leafs, diameter of bulbs, and weight of bulbs. The application of rabbit manure on ultisol soil media was able to increase pH, nitrogen, phosphorus, and cation exchange capacity, vice versa decreased the content Potassium.

Rabbit manure compost as a peat substitute for compound growing media: Proportioning optimization according to physiochemical characteristics and seedling effects

“…The exception was the high EC value. This result is consistent with previous studies ( Chang et al., 2021 ; Ikrarwati et al., 2021 ).…”

“…The exception was the high EC value. This result is consistent with previous studies (Chang et al, 2021;Ikrarwati et al, 2021). Appropriate physicochemical properties are required, but the most critical in the optimization of the ratio of the rabbit manure compound growing media would be the seedling effects, which is a direct and objective evaluation.…”

“…Similarly, Mg and N engage in many processes in plant photosynthesis, respiration, carbohydrate, and protein synthesis ( Silva et al., 2017 ; Pereira et al., 2020 ). At the same time, P provides energy for plant development ( Ikrarwati et al., 2021 ), showing that the growth performance of seedlings might be due to the increase of nutrients in the rabbit manure compound growing media. This result indicated that seedling effects could be promoted by enhancing the nutrition of growing media.…”

“…The National Livestock Station of China recommends that livestock and poultry waste should be composted to manufacture growing media trays or growing media as one of the effective ways to recycle biomass (Meng et al, 2019;Feng et al, 2020;Xu et al, 2021). Composted rabbit manure is considered suitable for use as solid growing media because of its low moisture (means low costs on collection and transport), low heavy metal (means high plant safety), high lignocellulose (means good porosity), and high nutrition (means good fertilizer effect) (Pereira et al, 2020;Ikrarwati et al, 2021;Li et al, 2022). Mahmoud et al (2014) explored the use of rabbit manure in organic tomato (Solanum lycopersicum L.) transplants and observed interesting fertilizer effects.…”

Komposisi Media Tanam Organik terhadap Pertumbuhan dan Produksi Jahe Merah (Zingiber officinale var. rubrum) di Polybag

“…Hasil ini disebabkan pertumbuhan daun sangat dipengaruhi oleh kandungan nutrisi media. Aplikasi pupuk kotoran kambing dapat meningkatkan Ph, nitrogen, fosfor, kapasitas tukar kation (Ikrarwati et al 2021). Perlakuan media tanam dengan takaran dan bahan yang tepat dapat membantu menjaga kadar air dan dapat menyesuaikan kebutuhan tanaman (Anwar dan Azizah 2020).…”
