Abstract

ABSTRACT The use of eggshells as an alternative source of calcium carbonate for groundnut can reduce the impact on the natural reserves of limestone, a non-renewable natural source. This study aimed to investigate the effects of eggshell powder application on the growth and yield of groundnut. The calcium treatments were lime application (A0) at 500 kg ha−1 and four rates of eggshell powder application including A1 (200 kg ha−1), A2 (300 kg ha−1), A3 (400 kg ha−1), and A4 (500 kg ha−1). Two application times, T1 (applying 5-days before sowing) and T2 (applying 5-days after flowering) were employed. The result showed that eggshell powder could be a useful alternative source to supply Ca for groundnut. Application of eggshell powder before sowing resulted in significantly higher pod yield and total calcium uptake with better growth parameters than after flowering. Increasing eggshell powder application rates also increased soil pH and calcium contents, and plant calcium uptake. The application rate of eggshell powder before sowing at the rate of 300 kg ha−1 produced the highest pod yield and was suggested to be optimum. Graphical Abstract

蛋壳粉作为钙源对花生生长和产量的影响

摘要使用蛋壳作为花生碳酸钙的替代来源，可以减少对石灰石自然储量的影响，石灰石是一种不可再生的自然资源。本研究旨在研究蛋壳粉对花生生长和产量的影响。钙处理是以500 kg ha−1施用石灰（A0）和四种蛋壳粉施用率，包括A1（200 kg ha−2）、A2（300 kg ha−3）、A3（400 kg ha−4）和A4（500 kg ha–1）。采用两次施用时间，T1（播种前施用5天）和T2（开花后施用5天后）。结果表明，蛋壳粉可作为花生钙的有效替代来源。播种前施用蛋壳粉可显著提高豆荚产量和总钙吸收量，且生长参数优于开花后。蛋壳粉施用量的增加也增加了土壤pH值和钙含量，并增加了植物对钙的吸收。蛋壳粉在播种前的施用量为300kg ha−1，产荚量最高，并被认为是最佳的。图形摘要

期刊介绍： Plant Production Science publishes original research reports on field crops and resource plants, their production and related subjects, covering a wide range of sciences; physiology, biotechnology, morphology, ecology, cropping system, production technology and post harvest management. Studies on plant production with special attention to resource management and the environment are also welcome. Field surveys on cropping or farming system are also accepted. Articles with a background in other research areas such as soil science, meteorology, biometry, product process and plant protection will be accepted as long as they are significantly related to plant production.
