Effect of intercropping madumbe (Colocasia esculenta) and rice (Oryza sativa L.) on yield and land productivity under different irrigation water management techniques with effluent water

The need for the optimal use of land, without a yield penalty, in urban and peri-urban (UP) settlements is vital. This study investigated the effect of intercropping madumbe and rice with respect to yield and land productivity when irrigated with anaerobic baffled reactor (ABR) effluent under different irrigation water management techniques. It was hypothesized that intercropping under different irrigation water management techniques has no effect on the yield and land productivity. Field trials were conducted in the 2017 and 2018 cropping seasons with ABR effluent (without fertilizer) at the Newlands Mashu Experimental Site, Newlands East, Durban, South Africa. A randomized complete block design with 3 replications; cropping treatments of sole madumbe, sole rice and madumbe + rice (intercrop) and irrigation treatments of alternate wetting and drying (AWD), continuous flood irrigation (CFI) and wetting without flooding (WWF) was used. Growth and yield parameters at harvest were determined. Thereafter, land equivalent ratio (LER) was calculated to evaluate the productivity of the intercrop. The effect of intercropping was significant (P < 0.05) on the total number of irrigation events and total water use. There was a significant reduction (P < 0.05) in plant heights of both madumbe and rice at intercrop. However, the effect on plant height for treatment CFI was positive but not significant (P > 0.05) for both seasons. A significant (P < 0.05) reduction also occurred in the number of madumbe leaves/plant, and panicles/plant and tillers/plant for rice. Intercropping significantly reduced (P < 0.05) madumbe corm and rice grain yield over the two seasons relative to sole cropping. LER showed that intercropping madumbe with rice was not more productive (LER < 1) than sole cropping of madumbe. It was concluded that over the two-season period, intercropping madumbe and rice do not yield appreciably under any of the three irrigation management techniques applied and the study hypothesis is thus rejected.

Abstract This study evaluated the effects of irrigation water management techniques on the growth and yield parameters of madumbe (Colocasia esculenta) irrigated with anaerobic filter (AF) effluent. The irrigation water management treatments considered were alternate wetting and drying (AWD), continuous flooding irrigation (CFI) and wetting without flooding (WWF). It was hypothesized that irrigation techniques with anaerobic baffled reactor (ABR) effluent have a significant effect on the growth and yield of madumbe. The effects of the treatments were significant (P < 0.05) on the number of irrigation events, amount of irrigated water and daily water balance. The treatments had no effect on the growth parameters (plant height, leaf number and leaf area index (LAI) (P > 0.05)). The treatments effects were, however, highly significant (P < 0.001) on the yield components (biomass, corm mass, corm number, corm size, harvest index), corm yield and water productivity (WP). AWD treatments had the highest WP. The highest average corm yields of 7.5 and 9.84 t/ha for WWF treatments for 2017 and 2018 seasons were obtained. It is concluded from this study that both AWD and CFI resulted in yield reduction compared with WWF, and as such, is not recommended to improve the productivity of madumbe.

This experiment was conducted to study the effect of irrigation intervals on growth, yield and its components and some of the chemical characteristics of the soil after the harvest of quinoa (Chenopodium quinoa willd) plant. Three treatments were used as follow: T1 (twice irrigation every week, which is the common in the region), T2 (once irrigation every week) and T3 (twice irrigation every two weeks) using in a randomized complete block design with four replicates. The crop coefficient (Kc) value differed according to the stage of growth where the results showed that the T2 treatment gave the highest mean in all the studied traits followed by the T3 treatment in all traits except the number of seed/m2. The results also confirmed that the increase in water reduced the agronomic traits such as harvest index, number of seeds and yield of seeds and straw/m2. Also it showed that the pH values in soils were not significantly affected by irrigation, while Ec significantly affected. Correlation coefficient was negative with the most traits and low with the number of grain (0.34) under overall studied treatments which confirms that quinoa is a plant that needs limited amounts of irrigation water. On the other hand there was positive strong correlation between the harvest index and grain yield (0.92). The results showed that moisture stress treatments increased the concentration of the ionic, NH4-N and NO3-N significantly compared to soils which do not have moisture stress (T1, T2). We assume that the development based on Kc during growth-stages helps in irrigation management and provides precise water applications for quinoa plant. These results indicate that the water requirements of quinoa plant are limited and that quinoa plant growth is not affected by the lack of irrigation water on the crop and its qualities.

Damage to irrigation areas in Indonesia covering an area of 0.37 million hectares for severe damage and an area of 1.25 million hectares for moderate and mild damage, has an impact on Indonesia's ability in rice production; rice imports were almost half a century, and only the adequacy of rice was 2 X, i.e. 1984 and 2009. This was due to low irrigation services which resulted in less optimal carrying capacity of food security. The deterioration in the function of irrigation services can be grouped into 5 causes of low irrigation pillars, namely: vulnerability of water sources, lack of irrigation infrastructure, low irrigation water management, weak management institutions, and low human resources. The cause will be eliminated by the irrigation modernization program by working on these five pillars. One of the pillars in the modernization of irrigation that needs to be improved is the irrigation management system. The purpose of this paper is to contribute ideas in improving the irrigation management system in Indonesia. The author has conducted observations and research on several irrigation areas, both the authority of the Central, Provincial and District Governments, especially visits to DI Wadaslintang, Central Java and DI Bondoyudo, East Java concerning irrigation water management systems. What stands out is the low level of irrigation services due to the inefficient irrigation water management system in Indonesia, in addition to the nature of service-based provision and not service-oriented based on farmers' needs. Identification wascarried out on the DI to find out the reasons for the low irrigation water management system, namely: orientation to water supply, calculation of irrigation requirements, water allocation method, irrigation water distribution schedule, irrigation water loss, irrigation operational steps, irrigation water productivity measurement This study analyzes the factors causing the low irrigation water management system while making a formula for the improvement proposal in the form of 7 steps.

Irrigation Water Demand

Kiladeda River in Pangani Basin, Tanzania plays a vital role of providing water for agricultural activities of the sub-catchment. However, it is experiencing a problem of inequitable distribution of irrigation water among farmers. Cross-sectional data was collected from farmers both in upstream and downstream using questionnaires, while river discharge measurements were conducted in referenced spot gauging stations. WEAP model was used to analyze water demand and allocation among farmers. Furrow irrigation (94%) and plastic buckets (6%) were the main irrigation water management practices. The model results revealed a water shortage of 46.4% of the total irrigation water required. The annual irrigation water demand and unmet demand were 13.93mm3 and 7.47mm3, respectively, and are both expected to increase twice in 2020. This high water demand for irrigation could be the main cause of excessive water abstraction. A partnering approach is recommended to improve irrigation water management, reviewing of laws, regulations, and water rights.

Abstract The study evaluated the effect of irrigation management techniques using anaerobic baffled reactor (ABR) effluent on the growth and yield of rice. It was hypothesized that irrigation techniques with ABR effluent have a significant effect on the growth, yield of rice, water productivity (WP) and water balance (WB). The experimental setup was a randomized complete block design for 2017 and 2018 cropping seasons, three treatments each with three replications. The treatments were alternating wetting and drying (AWD), continuous flooding irrigation (CFI) and wetting without flooding (WWF). The effect of irrigation management techniques was significant (P < 0.05) for the 2017 season but insignificant (P > 0.05) in 2018 on the yield. The effect of irrigation treatments on WP was significant (P < 0.05). The effects were not significant (P > 0.05) on the plant height, leave area index (LAI) and number of tillers per plant. However, the effect was significant (P < 0.05) on the number of panicles per plant. The effects of irrigation treatments were significant (P < 0.05) on number of irrigation, amount of irrigation, total water use and daily field WB. In conclusion, the result proved the acceptability of the hypothesis. AWD irrigation with ABR effluent should be encouraged among rice farmers.

AbstractThe objective of this paper was to develop agro-climatic zones in the old cultivated lands of Egypt in the Nile Delta and Valley using climate normals from 1985–2014 to facilitate better irrigation water management under water scarcity conditions. 30-year monthly climate data were collected for 17 agricultural governorates in Egypt and yearly averages and 30-year averages were calculated. BISm model was used to calculate yearly averages of potential evapotranspiration (PET) and 30-year average for each governorate. Analysis of variance was done using one factor randomize complete block design, with number of years as replicates. Furthermore, the mean, the range and R2 were calculated to test the strength of the relationship between PET and climate elements. The means of PET for each governorate was separated and ranked in ascending order using least significant difference test (LSD0.05). The results identified 7 agro-climatic zones (LSD0.05 = 0.146). These zones were: (1) Alexandria; (2) Demiatte, Kafr El-Sheikh and Dakhlia; (3) El-Behira, and El-Gharbia; (4) El-Minofia, El-Sharkia, El-Kalubia, Giza and El-Fayom; (5) Beni Sweif, El-Minia, Assuit and Sohag; (6) Qena; and (7) Aswan. Such zoning will increase the ability of the Egyptian policy makers to prepare the appropriate water management and development policies as a result of the availability of proper information on each zone aiming at efficient use of the limited water resources.
