The objective of this study was to assess the effect mix-cropping, Yangtsepa corn variety with legume Sesbania, and single cropping on forage yield quality at 60-, 90-, 120-days harvest. Randomized Complete Block Design (RCBD) three replications used as an experimental design. pea were line sown 20 cm apart a seed ratio 50:50. results showed higher (26.1 t/ha), dry matter 23.83% 120-day overall...

Four field experiments were conducted to study the effect of Sesbania rostrata and Aeschynomene afraspera as rotational and green manure crops on the population dynamics of Hirschmanniella mucronata and H. oryzae, and subsequent rice yields. The sequential cropping of the legumes with rice controlled both nematode species. In two experiments, yield of rice was related to the nematode population...

Two powdery mildew species have been collected from Iran. For the first time, Erysiphe magnifica on Magnolia sp. was identified from Iran based on morphological and molecular characteristics. Erysiphe corylacearum was collected for the second time in the country and reported for the first time from Guilan province. There are some polymorphisms in ITS-rDNA sequences of...
