Abstract
Soil fertility degradation is associated with continued cultivation of crop and without further addition of organic amendments. Improving the productivity of low fertile soils is a key to achieve the target of food production and tackling global food crises. A field study was conducted during 2022 to observe the effect of bone meal compost (BMC) on the growth and ion content of banana crop. The field study was organized at the experimental site of Sindh Agricultural University Tandojam in a three-replicated randomized complete block design. Each block was 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 no chemical fertilizers were used, CK3: BMC = 7.0 t ha-1 with recommended NPK (N=300, P=250 and K=500) kg ha-1. Bone meal compost with inorganic fertilizer (BMC+IF) showed remarkable positive effects on banana growth and soil quality. However, 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 observed in CK3. Moreover, the root length was decreased by 8.77% in CK3. The maximum increase in leaf sap ions was observed with the application of bone meal compost with recommended inorganic fertilizer. The maximum increase in sap nitrogen was 38.29%, phosphorus 59.35%, potassium 22.51% and calcium were increased up to 44.92% where plants were 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 findings of experimental results demonstrate the effectiveness 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
