Abstract

The reuse of organic wastes in agriculture is an appropriate method for environment management and providing nutrients to the plants. The objective of this study is to utilize possibility of agricultural waste as component of growing media and comparative evaluation of best potting media for flower production. The research was conducted at Floriculture Research Area, Institute of Horticultural Sciences, University of Agriculture, Faisalabad. There were total four treatments (garden soil, biochar + peat moss + leaf compost, leaf compost + soil, peanut shell compost + soil, rice straw + soil). Each treatment was replicated three times, having 10 plants each. Different agricultural waste materials such as leaf compost, peanut shell compost, rice straw and biochar were used as source for quality growth of Stock and Geranium. Physio-chemical analysis (N, P, K, pH, EC) were best in the growing media comprising biochar + peat moss + leaf compost. The experiment was arranged according to Completely Randomized Design (CRD) under factorial arrangement. The results regarding maximum plant height (57.4 cm), number of leaves per plant (62.5), root length (43.1 cm), number of flowers (31.6), flower diameter (4.8 cm), evapotranspiration rate (7.38 mol/m²/s), transpiration rate (46.4 mmol/m²/s) and leaf total chlorophyll contents (81.0 SPAD) were recorded in biochar + peat moss + leaf compost media while maximum leaf area (46.58 cm²), photosynthetic rate (2.11 μmol m²/s), stomatal conductance (1.73 mol/m²/s), respiration rate (416.67), internal CO₂ (375.67) and minimum days to first flower emergence (43.8) were observed in peanut shell + soil media. Statistically all the parameters were positively correlated with each other.

在农业中再利用有机废物是环境管理和为植物提供营养的一种适当方法。这项研究的目的是利用农业废料作为生长培养基的组成部分，并比较评估用于花卉生产的最佳盆栽培养基。这项研究是在费萨拉巴德农业大学园艺科学研究所花卉研究区进行的。总共进行了四种处理（花园土壤，生物炭+泥炭藓+叶堆肥，叶堆肥+土壤，花生壳堆肥+土壤，稻草+土壤）。每种处理重复三次，每次有10株植物。叶堆肥，花生壳堆肥，稻草和生物炭等不同的农业废料被用作原料和天竺葵的优质生长来源。理化分析（N，P，K，pH，EC）最适合包含生物炭+泥炭藓+叶片堆肥的生长培养基。实验是根据完全随机设计（CRD）在析因排列下进行排列的。关于最大植物高度（57.4 cm），每株植物的叶子数（62.5），根长（43.1 cm），花数（31.6），花直径（4.8 cm），蒸散速率（7.38 mol / m）的结果² / s），蒸腾速率（46.4 mmol / m ² / s）和叶片总叶绿素含量（81.0 SPAD）记录在生物炭+泥炭藓+叶片堆肥培养基中，而最大叶片面积（46.58 cm ²），光合速率（2.11）微摩尔米² /秒），气孔导度（1.73摩尔/米² /秒），呼吸率（416.67），内部CO ₂（375.67）和最小天至第一花出现（43.8）在花生壳+土壤媒体观察。统计上所有参数彼此正相关。
