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...

Sustainable nutrient management approaches could improve production and quality without affecting soil health. We conducted a field experiment to investigate the interactive effects of mulching (no mulch, plastic straw mulch) nanobiochar (NBC) foliar application on biomass, contents, metabolites in leaf curd cauliflower (Brassica oleracea var. botrytis). After 20 days transplantation, NBC (0.1%...

Aliphatic aromatic copolyester films, poly(butylene adipate-co-terephthalate) or PBAT, are susceptible to photodegradation, leading to main chain scission and crosslinking. The presence of crosslinked structures not only decreased the mechanical properties of the film due to embrittlement, but also hindered the biodegradation process by limiting access of water and microorganisms to the polymer...

Purpose: Water saving practices are crucial for crop production in drought prone areas. This study was conducted Bugesera District, the Eastern Province of Rwanda. The objective to determine effect irrigation levels and mulching types on growth yields beans. 
 Methodology: A split plot experiment consisting three as main plots (no mulch, grass mulch plastic mulch) subplots, a Randomized Co...
