Ensuring household food security through enhanced production of pechay (Brassica rapa L.) as influenced by different levels of carbonized rice hull integration

Abstract Household gardens have been a staple of many rural areas in the region. However, due to limited space, need intensify productivity while maintaining our natural resources has risen forefront research innovativeness. The and economic efficiency pechay applied with varying rates carbonized rice hull (CRH) were evaluated from February 2021 April 2021. study was laid out Randomized Complete Block Design five (5) growing media as treatments (T1 - garden soil recommended rate NPK; T2 (GM) consisting mixtures soil, chicken dung, coco peat; T3 GM + 5% CRH; T4 10% T5 15% CRH) three (3) replications. Results revealed that integration CRH specialized mixed (T3) significantly increased yield attaining 102.13 kg per 100 m2. Utilization (T2, T3, T4, T5) either or without higher dry matter which than plants harvested plots grown purely soil. Cost return analysis production utilizing obtained highest expenses Php 2.57 rest treatments. concludes addition is promising based on its performance cost invested, thus, it highly recommended.
