Hamelmalo region. Through the survey, 4 diseases namely, early blight, late blight, powdery mildew and wilt and 2 insects: Helicoverpa armigera and Tuta absoluta were recorded. The main objective of the study was to undertake survey for the incidence of early blight and powdery mildew of tomato caused by Alternaria solani and Oidium neolycopersici respectively. The maximum disease incidence due to early blight was 56.28% in F5 and minimum was 19.05% in seven days interval during survey whereas in case of powdery mildew the maximum and minimum was 38.96% in F2 and 13.43% in F5 respectively. Overall average for higher leaf infection in early blight and powdery mildew of tomato were recorded 41.85% and 34.63%, respectively. The average of disease complex incidence of 71.6% and 62.60% was recorded in F6 and F4, respectively.
This study contributes about incidence and severity of tomato diseases in Sub zoba Hamelmalo of Eritrea. Research conducted about the insect pest and diseases occurrence in tomato in this area. This study can be used for further reference for future research work in particular area.

Various maize researchers have been conducting experiments to know the effect of sowing date on maize seed yield and quality, which explored a vast variation in the results. In some countries, early sowing of maize gave good yields besides quality seed and at the same time, in some countries late sowing yielded better and posses’ high quality seed. Despite of all these differences in sowing period, many scientists and farmers opined that early and mid early sowings in India resulted good yields and high quality seed.
This study is one of very few studies which have investigated on effect of sowing date on various aspects of maize mainly used in the context of climate change, which is a most important factor in global issues.
