Abstract

Water spinach (Ipomoea reptans Poir) had been identified as a nutritious vegetable with high demand in Indonesia. Besides, this plant also has been evidenced to play an important role in environmental cleaning as phytoremediator. The study about the effect of organic fertilizers on the growth and yield of water spinach (Ipomoea reptans Poir) has been conducted in the Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. The study aims to investigate the most effective type of fertilizers and the dose for water spinach’s (Ipomoea reptans Poir) growth and yield. A Completely Randomized Factorial Design was designed for the experiment with two factors and three repetitions. The first factor is the type of fertilizer (chicken manure, cow manure, and compost), and the second factor is the dose of the fertilizer (1:1, 2:1, and 3:1). The parameters such as plant height, number of shoots, number of leaves, fresh weight, dry weight, leaf’s total chlorophyll content, and water content were measured to evaluate plant growth and yield. The General Linear Model used SPSS 21 programs was applied to analyze the collected data. Study results revealed that cow manure increased plant growth and yield significantly with dose 2:1 as the finest treatment, followed by dose 3:1. Cow manure also increased total chlorophyll content (8.0574c mg. L-1), with the most suitable dose was 2:1 (8.2807 mg. L-1). The plant’s water content tended to be high in chicken manure (93%), and the lower water content was in cow manure with dose 3:1 (87.5%).

Abstract

More foods are required to fulfill human need. The limitation of the farming area is leading to intensification system in crop cultivation, so the use of chemical properties and environmental destruction cannot be denied. However, this industrial practice in the crop system has caused many adverse effects on ecological balance and human health. Many severe impacts of industrial agriculture practices have been reported, including soil erosion, groundwater contamination, loss of productivity, depletion of fossil resources, air pollution, new threats to human health and safety. Many experts agreed that sustainable agriculture seems to be an effective way to solve these issues. Modern plant breeding is now a popular approach to provide superior crop cultivars that can minimize adverse effects of agriculture practices because humans can recognize and manipulated genes through this method. Recently, the application of molecular markers in plant breeding selection has been brought enthusiasm for plant breeders. Marker-assisted selection (MAS) has been evidenced to be a beneficial technique in plant breeding. Through this approach, the selection process of parents and progenies in the breeding process could be more efficient. Plant breeding is influential in crop production achievement because this effort is connected with the adaptability and stability of the varieties in many different environmental circumstances. Plant breeding also focuses on agriculture sustainability due to its effort to produces durable disease resistance, abiotic stress tolerance, nutrients, and water-use efficiency.
