THE EFFECT OF SOME ORGANIC MANURES AND INSECTICIDES ON SUGAR BEET PRODUCTIVITY AND POPULATION DYNAMIC OF BEET FLY, Pegomya mixta VILL

Abstract

The effect of some organic soil amendments such as cattle, poultry and sheep manures and four insecticides nudrin 90%, selecron 72%, tracer 24% and vertmik 1.8% and their interaction on sugar beet productivity and the infestation rate of beet fly, P. mixta were carried out at Damanhour and Nubariya regions under field conditions. The results raveled that population density of P. mixta, root yield, top yield, sugar yield and quality parameters were significantly affected by all organic manures and insecticides treatments. Generally, the highest accumulative larvae of P. mixta recorded with poultry manure followed by cattle manure and sheep manure in Damanhour and Nubariya regions. Also, in two locations poultry manure gave remarkable results in suppression in root, top and sugar yields as well as sucrose and purity% compared with cattle and sheep manures. All tested insecticides in the two locations significantly reduced the population density of beet fly, P. mixta on sugar beet plants in comparison with the cheek treatment. Sugar beet plants sprayed by selecron 72% the reduction% of P. mixta population increased with the time elapsed treatment. Selecron 72% was the most effective against P. mixta followed by tracer 24%, vertmic1.8% and nudrin 90%. Also selecron 72% was ranked the first in root and top yield, however, sugar yields gained the highest value by tracer treatment. Top, root and sugar yields, T.S.S.% and purity% were significantly affected by the interaction between tested organic manure, and insecticides. The highest top, root and sugar yields were obtained with (cattle manure x selecron 72%), (poultry manure x tracer 24%) and (cattle manure x tracer 24%) treatments, respectively. However the highest values of T.S.S. and purity% were obtained with (poultry manure x tracer 24%) treatment.

RESPONSE OF SOME SUGAR BEET VARIETIES TO FOLIAR SPRAYING WITH COMPOST TEA AND ITS RELATIONSHIP WITH TWO SUGAR BEET INSECTS, BEET FLY, (Pegomya mixta Vill.) AND TORTOISE BEETLE (Cassida vittata Vill.) UNDER NEWLY RECLAIMED SANDY SOIL

“…However, there was significant differences among the three mean compost tea levels (0, 15 and 20 L/fed) which was recorded 26.86, 33.0 and 38.43 larvae, respectively in the second season. These results were harmony with Abo El-Ftooh et. al.…”

Effect of Nitrogen Fertilizer and Compost Rates on Yield and Quality of Sugar Beet Grown in Sandy Soil Under Drip Irrigation System

“…These advantages lead to the increase in soil fertility which led in turn to increasing of the productivity of plants as illustrated by El-Ghareib et al (2012). Furthermore, the obtained results are in agreement with those reported by El-Geddawy et al (2003), Abo El-Ftooh et al (2012), Abou El-Magd et al (2012, Badawi et al (2013) and Soliman et al (2014).…”

“…Gomaa et al (2007) showed that application of compost at rate of 2 t/fad., to sugar beet caused significant increase in Na, K, alpha amino-N and sugar loss to molasses percentages as compared to without compost application, while, sucrose (%) did not vary significantly by compost application (combined analysis). Abo El-Ftooh et al (2012) revealed that poultry manure gave remarkable results in suppression in root, top and sugar yields as well as sucrose and purity (%) compared with cattle and sheep manures. Abou El-Magd et al (2012) showed that, root yield of sugar beet and yield components (top yield, root diameter, root length, sucrose (%), juice purity (%), gross sugar yield and recoverable sugar %) significantly augmented by the application of FYM.…”

Evaluation of Various Organic Amendment Sources to Improve the Root Yield and Sugar Contents of Sugar Beet Genotypes (Beta vulgaris L.) under Arid Environments

“…Our results are in agreement with the results that show higher growth and yield traits with the soil amendment of poultry manure. This is due to an increased mobility of micro (Fe, Mn, Cu, B and Zn)-and macro-nutrients (N, P, K, Ca and Mg) after decomposition of poultry manure [47,48]. Our results present proof of a study that has shown higher growth traits of cotton with the application of poultry manure due to an improvement in soil-available nitrogen, potassium and phosphorus contents and soil organic matter [7].…”
