Abstract

Phosphorus (P) is the second most important macronutrient both for plants and other living organisms. However, due to its fixation with soil collides; it becomes unavailable to plants and hence cannot enter the food chain. The effect of combination of mycorrhizae and different organic amendments on P uptake and plant growth of brinjal (Solanum melongena) was evaluated in a pot trial, conducted at wire house of Institute of Soil and Environmental Sciences, University of Agriculture Faisalabad. Each treatment was composed of one type of organic amendment (i.e. farmyard manure (FYM), biogas slurry (BGS), poultry manure and compost) at the rate of 1.5% w/w and mycorrhizae. Results showed that the combined application of mycorrhizae and organic amendment improved plant growth and enhanced P uptake. Improved root length, shoot height and leaf canopy was observed in FYM+mycorrhizae and BGS+mycorrhizae combinations. Similarly, enhanced P uptake improved photosynthetic activity and high biomass was observed in BGS+mycorrhizae combinations. The use of mycorrhizae and organic amendments appeared to be efficient in improving P uptake up to 53.45% and plant growth 64.32%. It is concluded that practicing this in the field can be cost effective approach and reduce environmental risk by reducing application of chemical fertilizers.
菌根与有机改进剂促进茄子生长和磷吸收的相互作用
磷(P)是植物和其他生物的第二重要的宏量营养素。但由于其与土壤的固定作用而发生碰撞;植物无法获得它,因此无法进入食物链。在费萨拉巴德农业大学土壤与环境科学研究所进行了盆栽试验,研究了菌根与不同有机添加剂组合施用对茄子(Solanum melongena)磷吸收和植株生长的影响。每个处理由一种有机改良剂(即农家肥(FYM)、沼液(BGS)、禽粪和堆肥)以1.5% w/w的速率和菌根组成。结果表明,菌根与有机改剂剂配施可促进植株生长,提高磷素吸收。FYM+菌根和BGS+菌根组合显著提高了根长、茎高和叶冠层。同样,BGS+菌根组合的P吸收增加,光合活性提高,生物量增加。施用菌根和有机改进剂对磷的吸收提高了53.45%,对植株的生长提高了64.32%。结果表明,在田间实施这一方法既具有成本效益,又能减少化肥的施用,降低环境风险。
