ABSTRACT

Soil organic matter and especially soil carbon is one the major component of soil health to sustain crop productivity and soil sustainability. The objectives of this study were to evaluate the most promising organic source for the highest wheat yield production and its impact on soil quality. This study was conducted to evaluate the effect of charcoal and compost on wheat yield and soil quality parameters. The experiment was conducted at Matta Circle as a wheat demonstration plot for the farmers of Matta Tehsil during the Rabi season of 2011–2012. The variety used was PIRSABAQ-2004. The experiment was laid down Randomized Complete Block Design (RCBD) with three replications, each replication with five treatments. The soil physicochemical characteristics were greatly influenced by charcoal and compost combine application. The results obtained from the study revealed that more tillers plant⁻¹, number of productive tillers, promising number of grain spike⁻¹, and 1000 grain weight was recorded with combine application of Compost and Charcoal @ 5 + 5 Mg ha⁻¹whereas highest biological yield and grain yield were noted with compost application @ 10 Mg ha⁻¹. The tallest plants were produced with 10 Mg ha⁻¹ charcoal application as compared to the combined application of compost + charcoal + inorganic fertilizers. We concluded that combined application of organic (charcoal + compost) and inorganic (NPK) fertilization could be promising in attaining high yields with the advantage of improved soil physicochemical characteristics of the soil to maintain the soil health, sustainability, soil productivity, and ultimately food security and increased yields.

摘要

土壤有机物，尤其是土壤碳是维持作物生产力和土壤可持续性的土壤健康的主要组成部分之一。这项研究的目的是评估小麦产量最高的最有希望的有机来源及其对土壤质量的影响。本研究旨在评估木炭和堆肥对小麦产量和土壤质量参数的影响。该实验在Matta Circle进行，该麦田是2011年至2012年Rabi季节期间Matta Tehsil农民的小麦示范地。使用的品种是PIRSABAQ-2004。该实验是通过三个重复进行的随机完全区组设计（RCBD），每个重复都有五种处理方法。木炭和堆肥联合施用对土壤理化特性影响很大。^-1，谷物穗的生产力的分蘖数目，有前途的数目^-1，和千粒重记录了与堆肥和木炭的结合应用@ 5 + 5镁公顷^-1而最高生物产量和谷粒产量，用堆肥应用注意到@ 10 Mg ha ^-1。最高的植物产量为10 Mg ha ^-1与堆肥+木炭+无机肥料的组合施用相比，木炭的施用量更大。我们得出的结论是，有机（木炭+堆肥）和无机（NPK）施肥的结合使用有望提高土壤的土壤理化特性，从而保持土壤健康，可持续性，土壤生产力，最终实现粮食增产，有望获得高产安全和提高产量。
