Nutrient management; Production and Protection of Sorghum
ISBN: 9783848431298 / Angielski / Miękka / 120 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The quality of sorghum is severely deteriorated by the Pyrilla perpusilla which is best controlled by Epiricania melanoleuca. Their tritrophic interaction is greatly affected by the host-plant quality. Plants growing in nutrient deficient environment are weak and vulnerable to pest attack. Macro- and micro-nutrients have a direct and greater impact on insect population, which is, although, primarily determined by genetic potential of plants, but can be modulated by mineral nutrition. This project was designed to evaluate impact of nutrient management on population dynamics of P. perpusilla...
