Abstract
ABSTRACT
The field experiment was conducted during 2022 to observe the effect of bone meal compost on the growth and nutrient content of banana crop. The experimental field was organized at the experimental site of Sindh Agricultural University Tandojam in a three-replicated randomized complete block design. Each block was further planted with 36 banana suckers of three months old. The treatments were designed as CK1: BMC=00 + recommended NPK (N=300, P=250 and K=500) kg ha-1, CK2: BMC 7.0 t ha-1 and zero use of chemical fertilizer, CK3: BMC 7.0 t ha-1 + recommended NPK (N=300, P=250 and K=500) kg ha-1. The findings of the results showed the beneficial effects of bone meal compost (BMC+IF) on banana health. Furthermore, the maximum increase in banana pseudo stem height 26.72%, number of leaves 15.74% leaf length 39.65%, leaf area index 36.37%, stem girth 38.47% were observe in CK3. Moreover, the root length was decrease 8.77% in CK3. However, the maximum increased in leaf sap ions was observed with the application of bone meal compost and recommended inorganic fertilizer. The maximum increase in sap nitrogen were 38.29%, phosphorus 59.35%, potassium 22.51% and calcium was increased up to 44.92% where plant was treated with bone meal compost along with recommended inorganic fertilizer in compression to other treatments. The improvements in soil macronutrient were observed with the amendment of bone meal compost and inorganic fertilizer. The maximum soil nitrogen content was 23.84%, phosphorus 31.75% and potassium 15.46% at the depths of 0-20 cm with the application of (BMC+IF). The overall results indicate the positive impact of bone meal compost and inorganic fertilizer for improving the growth and ion uptake in banana plants. Furthermore, amendment also improves the nutrient content in soil at both depths level.
