Abstract

Fruits and young shoot of Solanum nigrum Linn are harvested and consumed as indigenous vegetables by different Indonesian ethnics. Preharvest factors and harvesting methods to maximize the quality of S. nigrum produce is still unknown. In this study S. nigrum was grown in full irradiance and under shading and assessed for their growth, and fruit and shoot yields. The experiment was conducted at the Leuwikopo Experimental Farm in Bogor Agricultural University, Indonesia from April-July 2017. The results demonstrated that plants produced more fruits and shoots in full irradiance, i.e., 687.9 g and 211.1 g per plant, whereas only 331.1 g and 116.9 g per plant were produced in 50% shading. Although fruit and shoot production were superior under full irradiance, shoot-harvested plants had healthier leaves and life span of about 2 months longer thus facilitating longer availability. Canopy of shoot-harvested plants formed a columnar shape with 23 to 45 cm in height,  in contrast to spherical shape with 48 to 203 cm in height of the fruit-harvested plants. It is likely that shading level might contribute to farmers’ decision to harvest the shoots or fruits of S. nigrum. Further studies are needed to determine the effects of shading levels on nutritional quality of the shoots and fruits of S. nigrum.  Keywords: African nightshade, canopy architecture, harvesting method, indigenous vegetable, intercropping

Abstract

The fish feed waste and litters are organic matter that can be a source of nutrients for plants. This study is aimed to determine the growth and production of lettuce (Lactuca sativa L.) treated with wastewater from hard-lipped barb culture of several population densities. The research was carried out from April through June of 2020 at the greenhouse of the Agrotechnology Study Program, Faculty of Agriculture, Djuanda University, Bogor, Indonesia. The controlled study used a randomized block design with one factor, wastewater from fish population density of 10, 20 and 30 per 21 L of water, and AB Mix as a control. Plants treated with the AB Mix were significantly superior to those plants treated with the hard-lipped barb farming wastewater, demonstrated by taller plants, more and larger leaves, larger stem diameter and leaf area, longer roots, greater fresh and dry weight, as well as a higher leaf nitrate content. The aquaculture wastewater at the tested fish density in this study did not support optimal growth of lettuce, so lettuce production is still very low compared to those grown with the AB mix.
