Abstract

The recycling of nutrient-rich food waste reduces reliance on synthetic fertilizers, enhances soil quality, and improves plant growth. Existing studies have demonstrated the effectiveness of food waste, such as bone meal (B) and crab shell meal (S), as fertilizers; however, their combined use has not been investigated. This study aims to evaluate the effect of varying proportions of B and S fertilizers on the growth of Capsicum annuum (bell pepper) employing a random complete block design with 10 treatments (pure B, pure S, and a 50:50 BS mix, each at 7 g, 14 g, and 21 g) plus a control and three replicates. After eight biweekly observations and applying linear regression, it was revealed that B14 resulted in the tallest plant (34.28 ± 3.88 cm) and most leaves (28), which is attributed to its nitrogen content, while B21 had the largest leaf surface area (36.36 ± 36.96 cm²) as measured by ImageJ software. Rapid growth rates were seen in plants treated with B14, B21, and BS21, moderate growth rates in plants treated with S14, and stunted growth rates in control plants and plants treated with S7, S21, BS7, and BS14. Conversely, several treatments (B7, S7, S21, BS7, BS14, and control) showed stunted growth, likely due to low nutrient availability or the slow calcium decomposition rate from the S. Overall, B14 is the optimal fertilizer in terms of height, growth rate, and number of leaves, while B21 is the optimal fertilizer in terms of leaf surface area. BS21 showed potential as a low-cost, eco-friendly alternative to combined fertilizers for bell peppers.

Abstract in Filipino [Abstrak]

Nakakatulong ang pagre-recycle ng food waste na mayaman sa nutrients na mabawasan ang paggamit ng synthetic fertilizers, mapataas ang kalidad ng lupa, at mapalago ang mga halaman. Ipinakita na sa mga naunang pag-aaral ang bisa ng food waste gaya ng bone meal (B) at crab shell meal (S) bilang pataba; gayunpaman, hindi pa nasusuri ang pinagsamang paggamit ng mga ito. Layunin ng pag-aaral na itong suriin ang epekto ng iba’t ibang proporsyon ng B at S fertilizers sa growth ng Capsicum annuum (bell pepper) gamit ang randomized complete block design na may 10 treatments (pure B, pure S, at 50:50 BS mix, bawat isa sa 7 g, 14 g, at 21 g), kasama ang isang control at tatlong replicates. Matapos ang walong obserbasyon na isinagawa kada dalawang linggo at paggamit ng linear regression, natuklasan na ang B14 ay nagbunga ng pinakamataas na halaman (34.28 ± 3.88 cm) at pinakamaraming dahon (28), dahil sa nitrogen content nito, habang ang B21 ang may pinakamalaking leaf surface area (36.36 ± 36.96 cm²) batay sa sukat gamit ang ImageJ software. Nakita ang mabilis na growth rate sa mga halamang ginamitan ng B14, B21, at BS21, katamtamang growth rate sa S14, at mabagal o stunted na growth sa control at sa mga treatment na S7, S21, BS7, at BS14. Sa kabilang banda, ilang mga treatment (B7, S7, S21, BS7, BS14, at control) ang nagpakita rin ng stunted growth, na maaaring dulot ng mababang nutrient availability o mabagal na decomposition rate ng calcium mula sa S. Sa kabuoan, ang B14 ang pinaka-optimal na pataba batay sa taas, growth rate, at dami ng dahon, samantalang ang B21 ang pinaka-optimal para sa leaf surface area. Makikita rin ang potensyal ng BS21 bilang mababa ang gastos at eco-friendly na alternatibo sa pinagsamang mga fertilizer para sa mga bell pepper.
