Abstract: The experiment was conducted on research field of Sinana Agricultural Research center and Goro sub site in the highlands of Bale, south eastern Ethiopia under rain fed conditions during main cropping season of 2018 and 2019 to evaluate the integrated effects of pre-emergence (Dual gold 960 EC), post emergence (Gallant super) herbicides and hand weeding frequencies on yield and yield components of chick pea. The experiment consisted of eight weed management options; sole dual gold 960 EC, dual gold 960 EC + one time hand weeding at two weeks after crop emergence, and dual gold 960 EC at four weeks after crop emergence, sole gallant super, gallant super and one time hand weeding, weedy check, one time hand weeding at two weeks after crop emergence and two times hand weeding at two and four weeks after crop emergence along with two varieties (Dhera and Habru) laid out in randomized complete block (RCBD) with three replications. Analysis of variance showed that a significant difference in number of branches per plant, biological yield (kg ha-1), and grain yield (kg ha-1) were observed on different herbicidal treatments and hand weeding at Sinana while at Goro significant effects of integrated weed management were observed on dry matter, plant height, biological yield, grain yield and harvest index. The remains parameters studied at both locations were no significant for the treatments studied. The highest net return obtained from the application of 1.5 lit ha-1 dual gold 960 EC integrated with hand weeding at four weeks after crop emergence while the highest net return at Goro was obtained from two times hand weeding at two and four weeks after crop emergence and hence can be recommended for the end users. Moreover, similar experiments should be carried out in different cold and warmer regions of chickpea potential areas of the zone to confirm the present findings.

Abstract: Garlic (Allium sativum L.) belongs to the family Alliaceae and is the second most widely used Allium next to onion. Eastern Hararghe has a considerable potential agro ecology which is suitable for garlic production. However, lack of improved and adaptable varieties of this crop is the major production constraints to study area. A field experiment was conducted for two consecutive years (2019 and 20120) during the cropping season on farmers’ land at Kombolcha and Gursum districts. The objective of the study was to identify adaptable, high yielding and diseases tolerant garlic varieties for study area and similar agro ecology. The treatments arranged in randomized complete block design with three replications. The treatments were consisted of five garlic varieties (Chelenko I, Kuriftu, Tsedey 92, HL and Chefe) and one local check. The result of the study showed significant differences among varieties for all the recorded traits except days to maturity. Among the varieties, Tsedey 92 provided about 54.3% and 13.3% yield advantages over the local and standard check, respectively. Also Tsedey 92 was tolerant to rust disease than other varieties and local cultivar. Therefore, for sustainable garlic production and productivity in study area Tsedey 92 was recommended and need to be demonstrated.

Abstract: For sustainable space exploration there is need for torrential food supply. Apart from food in storage, constant production is vital as this could also serve as a source of Oxygen when activated during space expedition. However, the impact of gravity in crop development is significant. This study therefore, investigated the morphological and physiological responses of Maize (Zea mays) seedlings subjected to clinorotation. Agar Agar was used as source of nutrient for the developing seedlings. The Agar was prepared by measuring 1 – 1.5 g and made up to 100 ml with tap water. Seeds were collected in the seed bank of the Space-Earth Environment Research Laboratory, Benin City. Three sets of petri dishes were prepared and marked; one for normal surface, one rotated at 90°C and another set for clinorotation. Those for clinorotation were rotated at three different times; with 1, 2, and 3 rpm for 6 hrs respectively. The plumule, radicle and Enzyme activities were measured and analysed after four days. Results showed significant difference in germination parameters as occasioned by microgravity. Where as clinorotation enhanced radicule length (1.8-2.1cm), effect on plumule was minimal (p>0.05). Significant increase in CAT activity in the plumule was reported (7.59mol/sec) in the clinorotated (1rpm) seed compared to the control (2.56mol/sec). MDA activity in both radicle and plumule were higher than that of the control (p<0.05). Microscopic study of the cells was carried out using a binocular microscope (Labo) with a camera and result showed that the normal surface sample cells were arranged concentrically with spaces, while that of clinorotated seeds were arranged concentrically but highly packed with little spaces for the plumule. For the radicle, the normal surface sample cells were scattered within the plant with more spaces, while that of clinorotated were mostly clustered throughout.
