Abstract: Ground nut (Arachis hypogaea L.) is one of important oil crop grown in Ethiopia. However, its productivity is low due to in appropriate intra and inters spacing practice. The study was conducted in 2019 and 2020 main cropping season at two locations for two consecutive years in west Hararghe Zone, Ethiopia; The objective of this study was to determine the optimum inter- and intra-row spacing of ground nut for maximum yield and yield components. The experiment was laid out randomized complete block design with three replications in a factorial arrangement of three inter-rows (50cm, 60cm and 70 cm) and four intra-row (10cm, 15cm, 20cm and 25 cm) spacing using groundnut Werer-962 variety. From combined mean result observed inter- and intra-row spacing significant different for days to flowering, days to maturity, plant height, number of pods per plant, grain yield. While, non-significant different showed for number of seed per pod. The maximum number of pods per plant (40.86 and 40.18) was obtained from 60cm*25cm and 60cm*20cm inter- and intra-row spacing, respectively. The highest grain yield (2722kg ha−1) was obtained at interaction of 60cm * 20cm spacing, followed by (2622 kgha−1) at 60cm*25cm inter- and intra-row spacing. While the lowest (1542 ha−1 and 1592 ha−1) was obtained from 70cm*25cm and 70cm*20cm inter- and intra-row spacing, respectively. The optimum spacing was given 37.31% yield advantage than over control 60cm*10cm inter- and intra-row spacing. However, based on agronomic performance use of 60cm * 20cm spacing is promising for groundnut production in west Hararghe and similar agro ecologies.Abstract: Ground nut (Arachis hypogaea L.) is one of important oil crop grown in Ethiopia.

Abstract: Many irrigation schemes developed in Burundi indicate to perform below their potential. Major causes of poor performance are mainly due to the inequitable water distribution and mismanagement. This study aimed to evaluate the irrigation system using performance indicators and farmers’ knowledge. In this study, a float method was used for determining flow rate, the discharge and conveyance efficiency at the main secondary and tertiary canals. The task involved the determination of irrigation water allocation and distribution at main, secondary and tertiary canals. Based on the climatic data, the crop water requirement was determined and by discharge data, the conveyance efficiency, the adequacy, the efficiency, the dependability, the equity of water supply. We have also evaluated the productivity of agricultural water use by comparing the quantity of water delivery to the field within the output. The results indicate that 82.48, 80.40 and 66.38% of water conveyed by the system in lined main canal, lined secondary canal and unlined secondary canal, respectively reach the destined farms. The results show further more that the system of water distribution was good in terms of adequacy and poor in terms of efficiency and fair to both dependability and equity. The physical and economical water productivity was 0.97 kgm-3 and 0.45$m3 at head, 1.36 kgm-3 and 0.63$m3 at the middle and 1.41 kgm-3 and 0.65 at the tail. The results show further that the water productivity performance was found to be 0.72, 1.16, and 1.31 at the head, middle and tail, respectively. The findings from survey have shown that the majority of farmer lack of crop water requirement. The study suggests adding more efforts for improving efficiency, temporal uniformity and equity in water allocation.Abstract: Many irrigation schemes developed in Burundi indicate to perform below their potential.
