The writers determined the genetic basis of meloidoyne incognita –fusarium exosporium lycopersici disease which affected tomatoes as from the inoculations of progeny F2. The paper demonstrated the role of nematode in the disease interactions through resistance breakdown to F Oxysporum lycopersici in the presence of M. It showed that the cysts have a significant effect in the productivity of the important food crops.
This paper evaluates the impact of the H.avenae on the spring wheat yields in Northwest Pacific. The condition had been observed on the fields but had not been quantified. It was motivated by the variation in infestation between the fields in dry land and irrigated fields. Heterodera avenae is widely distributed in the western US. These are the regions where wheat is grown in the non-irrigated winter wheat and summer fallows in the regions of low rainfall. The social and economic pressures have motivated growers to pursue a transition into the summer fallow rotation to the no till annual spring cereals. These cereals are also grown in the irrigated fields. Spring wheat was, therefore, planted without aldicarb in determining the relationship between H.avenae and the yields under the irrigated and dry land in moderately infested lands. From the research, the spring wheat productivity was negatively correlated with the initial H.avenae populations.
This research paper aims to present valuable information and figures related to agricultural development plans in Saudi Arabia. This is done despite the unsuitable and harsh climate as well as other conditions for normal production in agriculture. This is because of the limited and deteriorating water availability for agricultural productivity. The paper focuses on the condition of Saudi Arabia in improving and increasing the production of agricultural products. The
