Abstract

Lettuce is a vegetable crop with a demand that continues to increase yearly. This situation is influenced by increasing public awareness of healthy lifestyles and urban farming practices. Diverse genetic sources are essential in plant breeding programs to form varieties with superior characteristics to increase productivity. One of the methods that can be done to improve genetic variation is by introduction. This research aims to study the morphological characteristics of three varieties of introduced lettuce. This research was conducted in the experimental field of the Faculty of Agriculture, Universitas Muhammadiyah Jakarta, from July to November 2022. The study compared three introduced lettuce varieties from Turkiye and three national commercial varieties. The morphological characteristics observed included qualitative (leaf shape, leaf vein shape, leaf tip shape, and leaf colour) and quantitative (crop height, number of leaves, leaf width, leaf length, harvest age, gross weight, and consumption weight). The results showed that only V4 had the same qualitative characteristics as its comparison variety (V1). The results also showed that in terms of quantitative characteristics, V4 and V5 had a higher resemblance to their comparator varieties (V1 and V2, respectively), while V6 had a further similarity to its comparator variety (V3). These introduced varieties have phenotypic variability that can be used as sources of plant genetics for plant breeding programs.

Abstract

ABSTRACTCover crops is widely used as biomulch because of its advantages for land conservation, weed control and increasing soil nutrients, especially in upland agriculture. The objective of the research was to study the growth and development of Arachis pintoi as biomulch in upland agriculture. The experiment was carried out at IPB Experimental Field from February until May 2014. Observation was done everyweek up to 12 weeks with 10 plants were used for each observation. One stolon of A. pintoi with 4 internodes was planted in each 0.25 m2 plot. The results showed that root initiation of A. pintoi was occured at 3 weeks after planting (wap) and produced 42.4 roots with average root length of 17.10 cm on 12 wap.A. pintoi had nett assimilation rate of 0.0023 g cm-2 per day and relative growth rate of 0.052 g per day. With this growth rate, A. pintoi covered 58% of 0.25 m2 plot and produced biomass 10.08 g per plant within 12 wap. A. pintoi produced flowers on 4 wap and pods on 7 wap. A. pintoi produced root nodules through mutualism symbiosis with local Rhizobium. The equation for rate of coverage is Coverage (%) = 5.273 Time (wap)-16.512; 100% land coverage can be reached on 22 wap. Based on the results of this study, A. pintoi is potential to be used as biomulch; however, a denser spacing must be applied for faster land coverage.Keywords: land coverage, mulch, Rhizobium, stolon
