The growth and yield of four varieties of lettuce (Lactuca sativa. L) in different planting media

Headnote

Abstract

Lettuce production in Central Kalimantan, which is still low due to non optimal cultivation techniques, especially in the selection of lettuce varieties that are tolerant to soil conditions which are less favorable for plant growth. The purpose of this study was to determine the growth and yield of four varieties of lettuce which are grown in different growing Medias that can be known adapted capable varieties to the growth environment. The used design was the Split Plot Design into completely randomized design pattern repeated four times. The Main plots are the growing media and the Hygiene Compartment is lettuce varieties (Lettuce Grend rapid, Lettuce mixes green leaves, red rapid and Lettuce delicato). The result shows the interaction between the four varieties and the planting media had significant effect on the parameters of leaves numbers and fresh weight. The interaction of red lettuce varieties rapid treatment on peat growing media is the best combination to increase leaves number as 11.25 strands and the wet weight of cropping as115.35 g.

INTRODUCTION

Different environments can lead to diversity of morphological structures and anatomical structures as a form of adaptation. Environmental conditions that can affect changes in plant structure include pH and soil texture (Buyer et al. 2010, Concostrina-Zubiri et al. 2018, Gliński 2018, Lal 2018). Adaptation test for lettuce varieties is one alternative that can be conducted to determine how far lettuce plants can grow and adapt well to suboptimal environmental conditions so that later can be determined the type of lettuce varieties that are adaptive to local agroclimate (Calabria et al. 2019, Concostrina-Zubiri et al. 2018, Hang et al. 2019, Li et al. 2018, Missio et al. 2018, Mostofa et al. 2018, Paraðikovi et al. 2018, Tkallch 2016).

Central Kalimantan is mostly dominated by marginal land such as peat and sandy soil which has physical, chemical and biological properties that are not beneficial for crop cultivation. The low rate of plant growth is...
