Investigations on Forage Yield, Yield Parameters of Oats Varieties and Lines Grown Under Irrigated Conditions in Konya (Published)
Oat is an important cereal as human food and animal feed. In this research, it was aimed to evaluate some oat (Avena sativa L.) genotypes (lines and cultivars) sown at the end of March for forage yield and forage quality parameters. Research was carried out in Konya irrigated conditions, in 2018 seasons with 12 oat genotypes [nine lines (BDY-1, BDY-2, BDY-3, BDY-4, BDY-5, BDY-6, BDY-7, BDY-8, BDY-9) and three were registered cultivars (Diriliş, Cheocota, Seydişehir)]. The trial was established according to the Randomized Blocks Experimental Design with three replications. Oats genotypes were harvested at milk to dough period. In research, the traits such as; days to heading, green forage yield, dry forage yield, plant height, the number of stems per square meter, the number of fertil stems per square meter, fertile cluster ratio, the number of node per stems, stem thickness, 10 stem weight, leaves weight, leaf stem ratio, cluster length, flag leaf length and the number of leaves per stems.

Growth Performance of Eleven Improved Cassava Varieties and their susceptibility to Some Insect Pests and Diseases in Humid Tropics, Rivers State (Published)
Study on the agronomic evaluation and disease resistance of eleven improved cassava varieties was carried out in Rivers State University Teaching and Research Farm in a Randomized Complete Block Design (RCBD). The eleven varieties assessed are TMS 30572, TMS 98/0510, TMS 98/0581, TMS 98/0505, TMS 92/0326, TME 419, TMS 01/1371, TMS 01/1368, TMS 07/0593, TMS 95/0289 and TMS 96/1632 were evaluated for plant height, leaf number, number of branches, number of flowers, insect infestation and disease incidence. The plant height of the cassava varieties revealed that eight varieties (TMS 01/1371, TMS 01/1368, TMS 30572, TME 419, TMS 98/0505, TMS 96/1632, TMS 98/0510 and TMS 07/0593) are tall varieties while TMS 98/0581, TMS 92/0326 and TMS 95/0289 are short varieties. The highest leaf number was recorded in TMS 01/1371 but the tall varieties like TMS 01/1368, TMS 96/1632 and TME 419 had low leaf number. TMS 98/0581, TMS 92/0326 and TMS 95/0289 were shown to have scanty leaves. TMS 01/1371 was significantly higher (P<0.05) than other varieties in plant height, leaf number and branches. Four varieties flowered namely TMS 07/0593, TMS 01/1371, TMS 30572 and TMS 98/0505. TMS 30572 and TMS 92/0326 were highly susceptible to both African Cassava Mosaic and Xanthomona sp. (Bacterial blight diseases) while TMS 95/0289, TMS 01/1368 and TMS 98/0505 were less susceptible to African Cassava Mosaic virus disease alone. Insect infestations (White fly: Bemisia sp. and Mealybugs: Phenacoccus sp.) on the tested varieties were significantly minimal though five cultivars (TMS 98/0505, TMS 96/1632, TMS 98/0510, TMS 98/0581 and TMS 95/0289) were completely resistant. Therefore, there is urgent need to withdraw the varieties that are susceptible, and use more of the varieties that are disease resistant for high crop yield, breeding and higher productivity.
