Plain and the influence of the hybrid, plant density, crop rotation, nutrient supply, weeds and irrigation on water use efficiency were studied. Choosing of the hybrid with the best water use efficiency is very important because a hybrid from 500–600 FAO group (Fundulea 376) in unirrigated conditions and a hybrid from FAO group over 600 (Fundulea 365) obtained the biggest water use efficiency; the hybrid Fundulea 365 obtained the highest irrigation water use efficiency, 20.1 kg yield gain 1 mm-1 irrigation water. One of the most known hybrid in the area is Turda super and the highest water use efficiency was obtained using the plant density of 55 000 plants/ha in unirrigated variant and 70 000 plants/ha in irrigated variant. The highest irrigation water use efficiency, 20.7 kg yield gain 1 mm-1, was obtained at 70 000 plants ha-1. In maize monoculture was obtained the lowest values of the water use efficiency in unirrigated and irrigated variant: in the wheat-maize crop rotation the values were higher than in maize monoculture and in the wheat-maize-soybean were registered the highest values. The same situation was registered regarding the irrigation water use efficiency. Farm manure (30 t ha-1) and especially manure (30 t ha-1) +chemical fertilizers (N90P45) determined a higher values of the water use efficiency in comparison with the control. In the variant with organic + mineral fertilization was registered the higher value (19.4 kg yield gain mm-1) of the irrigation water use efficiency. Water use efficiency was much lower in the variant with weeds in comparison with the variant without the weeds; the differences were of 69% in unirrigated variant and of 64% in irrigated variant, very significant statistically. Irrigation water use efficiency from variant with weeds was lower than the value registered in the variant without weeds; the difference (68%) was very significant statistically. In average in period 1976–2012, the irrigation determined the increasing in water use efficiency with 22%, 19.4 kg mm-1 vs. 15.8 kg mm-1, but not in all the years caused the irrigation increasing in water use efficiency in comparison with unirrigated maize. The results research emphasized the need of the optimization for technology elements studied and a better water use efficiency will be obtained.

Aims: The study determined the effect of soil fertility management (inorganic and organic N sources) and short term crop rotation (cereal – legumes cropping systems) on water use efficiency of wheat in high potential areas. Study Design: A randomized complete block design was used with split-split-plot arrangement replicated three times. Three factors evaluated included water harvesting (WH), crop rotation (CR) and soil fertility management (SFM). The data obtained were subjected to an analysis of variance (ANOVA) using Genstat statistical package while the mean separation was performed using least significance differences (P =.05). Place and Duration of Study: The trial was conducted at the Kenya Agricultural and Livestock Research Organization (KALRO) fields based in Njoro for three years between 2014 and 2016 during rainy seasons. Methodology: Water harvesting was evaluated at consisted of flat beds (WH1) and tied ridges (WH2), crop rotation was tested at four levels comprising of Wheat- Dolichos lablab (Lablab purpureum)-Wheat- L. purpureum (CR1); Wheat-Greenpea (P. sativum) –Wheat (Triticum aestivum L)- P. sativum (CR2); T. aestivum L-potato- P. sativum –Potato (Solanum tuberosum) (CR3); and Wheat-Wheat-Wheat-Wheat) (CR4). Six different soil fertility management (SFM) strategies evaluated included SFM1 = untreated control; SFM2 = Farm Yard Manure at 5 t ha-1; SFM3 = Green manure (L.eucaena triachandra) at 2.5 mt ha-1; SFM4 = Calcium Ammonium Nitrate (CAN) at 25 kg N ha-1; SFM5 = Calcuim Ammonium Nitrate at 50 kg N ha-1; and SFM6 = Ammonium Nitrate (CAN) at 75 kg N ha-1. The Water harvesting (WH) and SFM were fixed on the same plot at the form and rate for the entire period of the study while crops were rotated between seasons. Water use efficiency was derived as a ratio of water use and grain yield and biomass. Results: Results revealed significant (P =.05) effect of crop rotation and soil fertility management on water use efficiency. However, water harvesting did not influence. While interaction of CR and SFM significantly (P =.05) influenced WUE and grain yield. Significant influence was also observed on WUE due to an interaction between WH and SFM. Dolichos lablab (L. purpureum) and green pea as pre-crops resulted in higher yield than when potato was the pre-crop and continuous wheat.  Use of inorganic N fertilizer with L. purpureum as a pre-crop resulted in higher grain yield than all other soil fertility management strategies evaluated. In conclusion, the use of green pea as a pre-crop during the short rain followed by wheat in long rains is a beneficial crop rotation systems and a climate smart strategy. In addition, organic N sources should be recommended for sustainable wheat production because it will positively influence the accumulation and slow release of soil moisture for increased water use efficiency.

Porto Alegre - RS  1 RESUMO No Rio Grande do Sul cultiva-se o arroz como monocultura há pelo menos 5 décadas. Uma alternativa para introduzir-se rotação de cultura seria o cultivo do milho, aproveitando-se da estrutura de irrigação utilizada para o arroz. O objetivo deste trabalho é avaliar diferentes manejos de irrigação e drenagem visando introduzir o milho como alternativa para rotação de cultura em Gleissolo Háplico Distrófico Típico. O experimento foi conduzido nas safras de 2013/2014 e 2014/2015, na estação experimental do IRGA em Cachoeirinha-RS. Foram testados quatro tratamentos, todos com declividade de 0,08%, ao longo do comprimento das parcelas (79 m) e com três repetições: microcamalhão com irrigação por sulco; microcamalhão sem irrigação; sem microcamalhão com irrigação por lâminas superficiais (banhos); e sem microcamalhão sem irrigação. Foram avaliados alguns indicadores de rendimento do milho e a eficiência do uso da água (EUA) nas diferentes alternativas de manejos. Na safra 2013/2014 os resultados indicam produtividade superiores a 10 t ha-1 para o tratamento irrigado e com microcamalhão. Na safra de 2014/2015 não houve diferença significativa nos tratamentos. O milho utilizado como rotação de cultura com o arroz é tecnicamente viável com uso de irrigação e de uma drenagem eficiente. Palavras-chave: Zea mays; microcamalhão; solos mal drenados.  FARACO, J.R.; CASTRO, N.M.R.; LOUZADA, J.A.; SILVA, P.R.F., SCHOENFELD,R.; MAASS, M.B.; PAGLIARINI, N.YIELD AND WATER USE EFFICIENCY OF MAIZE IN RICE FLOODED AREAS WITH DIFFERENT IRRIGATION AND DRAINAGE MANAGEMENT    2 ABSTRACT Rio Grande do Sul practices rice monoculture for at least 5 decades. An alternative to introduce crop rotation would be the corn crop, taking advantage of the irrigation structure used for rice. The objective of this study is to evaluate different management of irrigation and drainage aimed to introduce corn as an alternative crop in Gleissolo Háplico Distrófico Típico. The experiment was conducted in 2013/2014 and 2014/2015, in IRGA's experimental station in Cachoeirinha-RS. Four treatments were tested, each with a slope of 0.08% along the length of parcels (79 m) and three replicates: furrow irrigation and small bund; no irrigation and small bund; basin irrigation and no small bund; and irrigation and no small bund. Were evaluated some income component of corn and the water use efficiency (USA) in the different alternatives managements. In 2013/2014 the productivity results indicate higher than 10 t ha-1 for the treatment and irrigated with microcamalhão. In 2014/2015 there was no significant difference in treatments. Corn used as crop rotation with rice is technically feasible with efficient irrigation and drainage management. Keywords: Zea mays; microcamalhão; poorly drained soils.
