Effect of Compost Made with Sludge and Organic Residues on Soil and Sugar Beet Crop in Morocco

Abstract

A B S T R A C TThe objective of this study was to determine the effects of the application of different doses of compost made with sludge and organic residues from plants on some soil characteristics, growth and yield of sugar beet (Beta vulgaris L.) grown in Moroccan soil having low organic matter. A field experiment was conducted and complete randomized block with four replicates was designed. Treatments consisted of control without any organic amendment and three concentrations of compost (2.5, 5.0 and 7.5 t haG 1 ). Results showed that, in general, application of at least 5 t haG 1 of compost increased soil organic matter along with C rates and other mineral nutrients such as N, P and K. Application of 5 t haG 1 of compost significantly increased sugar beet biomass and recoverable sugar yield. This beneficial effect was reversed with the highest dose of 7.5 t haG 1 .

Effect of some soil amendments on yield and quality traits of sugar beet ( Beta vulgaris L.) under water stress in sandy soil

“…The increase of sugar yield by application of compost or bentonite may be due to that it's role in increase each of root yield and sugar extractable as mentioned before. This finding agreed with obtained by of Kabil et al (2015).…”

“…While in the second season the highest value was 16.06% produced from the addition of 12 ton/ha bentonite to the soil. This finding agreed with obtaining by of Kabil et al (2015). However, compost led to increasing of photosynthetic process and leaf area which revealed in increase sugar production (Molnou et al, 2008).…”

Effect of long-term application of fertilizers on the yield and energy productivity of sugar beet

“…За вирощування буряків цукрових на біоенергетичні цілі важливими постають питання впливу добрив на їх біологічну та енергетичну продуктивність, щодо ефективності альтернативних систем удобрення, які передбачають внесення побічної продукції сільськогосподарських культур замість гною, якого сьогодні обмаль, як вплив добрив проявляються в їх довготривалому застосуванні [7], [8], [9].…”
