Sweetpotato ( Ipomoea batatas ) production in the northern United States is limited due to perceived barriers of a short growing season and relatively cool summer temperatures, yet recent studies have shown yield regions can be greater than national average when sweetpotatoes are grown with plastic mulch. A study was conducted northwest Washington evaluate productivity ‘Covington’ sweetpotato p...

ABSTRACT
 
 The purpose of this study is to determine the effect shading and mulching on microclimates in tomato plants. This used a Randomized Block Design (RBD) method with shade mulch treatment consisting 6 levels namely without (NTM), plastic (NMP), straw (NMJ) (TNTM) , (TNMP), (TNMJ). Each was repeated three times so that there were 18 experimental units. parameters observed are ...

Potato (Solanum tuberosum) is one of fourmajor food crops in the world. Weed control is a major component in potato production and has been accomplished using different methods, including but not limited to the use of herbicides and straw mulch. A combination of preemergence herbicide and straw mulch may improve weed control; however, no information is available for combining both methods, alon...

Three crops of cucumber were grown in succession in beds by use of trickle irrigation, plastic film mulch, and soil chemical treatments over a 17-month period, including a fallow winter season. Total yield for the three crops was highest (1208 quintals/ha) in film-mulched plots treated with MBR-CP, and next-highest in film-mulched plots treated with DD-MENCS (1094 quintals/ha); total yield was ...

Plastic reflective mulches significantly reduced populations of corn leafhopper, Dalbulus maidis (DeLong & Wolcott), adults and the incidence of corn stunt disease caused by Spiroplasma kunkelii (CSS) in late planted sweet corn (Zea mays L.). The reflective mulches were more effective than were either foliar or soil applied insecticides in managing both the leafhopper and the pathogen it transm...
