Effective Water

Dryland farming provides a promising opportunity in increasing agricultural production in rural areas. But, the lack of available water during dry season poses a problem in developing dryland farming. An effective water conservation technique should be developed to alleviate this problem. The use of a small farm reservoir (embung) can be considered as one viable option for such conservation techniques. The purpose of this research was to study the effectivity of small farm reservoirs to supply irrigation water for horticulture commodities. Two different types of small farm reservoir (SFR) were constructed in the micro catchment for the research, i.e. a) SFR built with concrete, b) SFR built without concrete. SFR built with concrete had higher water available for irrigation, which is 34% higher compared to SFR without concrete. In addition, the empirical equation that was used in this research was quite reliable in predicting colected water in the SFRs. Using 80% monthly rain probability, on average one small farm reservoir with dimension 8 m x 2m x 2 m was able to supply irrigation water for 100 m2 horticulture plants for the whole growing period. Keywords: Small farm reservoir, dry season, irrigation, dryland farming.

Alternative Irrigation

Irrigation water, particularly if applied overhead, could be an important source of bacterial contamination to fresh produce. The colonization, survival, and proliferation of exogenous bacterial pathogens can be strongly influenced by the produce microbiota. In this study, spinach grown in an organic field was irrigated with ground water and potential alternative irrigation water including reclaimed wastewater, and urban runoff water, over a period of 2 weeks. Water and spinach samples were collected before and after irrigation for bacterial plate count, qPCR, and community profiling using 16S rDNA high-throughput sequencing analyses. The average bacterial population densities on spinach (6.50 ± 0.04 log CFU/g, 7.40 ± 0.10 log 16S copies/g) were significantly higher than those in irrigation water (3.61 ± 0.12 log CFU/ml, 4.94 ± 0.13 log 16S copies/ml). The composition and relative abundance of spinach microbiomes varied with different types of irrigation waters; however, the most abundant microbial taxa on spinach were not significantly affected by the irrigation with different types of water. Shigella, Salmonella, Listeria, Campylobacter spp., and pathogenic Escherichia coli were not detected in this study. This study provides information on the microbial ecology of diverse bacterial communities on spinach surface after irrigation by different types of water, which can benefit future studies on the interaction of microbes on produce, and the prevention of foodborne pathogens and plant disease.

The Impact

In this study, ten oat genotypes (Alguda , Anatolia , Pimula ,Genzania ,Hamel, Icarda short ,Kangaroo ,Icarda tall ,Mitika and Possum) were used under the impact of three irrigation water types and two agricultural seasons. Performance and genetic and environmental interaction were studied according to Eberhart and Russel and cluster analysis for Days to anthesis , plant height ,flag leaf area,no.effective tillers , no.grains.panicul , 1000 grains weight and grain yield (t.he-1), We reached the most important results that was through obtaining statistically significant in analysis of variance table of the sources of difference in environments, genotypes and the interaction between them for all characteristics under study. Genotype (6) distinguished in no.effective tillers (141.06 tiller.m-2 ), no.grains.panicul-1 (66.89 grain.panicul-1) and grain yield (1.48 t.he-1) and genotype (1) in days to anthesis (110.70 day) and no.effective tillers (136.67 tiller.m-2) and the interaction between fourth environment and genotype (6) for no.grains.panicul (66.67 grains,panicul-1) .In addition to this uniqueness in performance, genotype (6) proved its stability for plant height, 1000 grains weight and grain yield (t.he-1) .These indices are feasible with evidence that they coincided with yield and some of its components, as well as to high stability to be implemented in future after testing with other factors. In addition to that, obtaining the state of the genetic distance between genotypes tested across environments, in particular genotype (8) with genotypes (6 and 7) and hence can be used in breeding programs, especially hybridization.

DINÂMICA DO ENTUPIMENTO DE GOTEJADORES EM FUNÇÃO DA APLICAÇÃO DE CARBONATO DE POTÁSSIO  Pedro Róbinson Fernandes de Medeiros; Rubens Duarte Coelho; Allan Cunha Barros; Ralini Ferreira de MeloDepartamento de Engenharia Rural, Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo, Piracicaba, SP,  [email protected]  1 RESUMO             O objetivo deste trabalho foi avaliar a dinâmica do entupimento de gotejadores em função da aplicação de carbonato de potássio e posterior aplicação de ácido nítrico na água de irrigação. O ensaio foi conduzido em bancada no laboratório de Hidráulica da ESALQ, utilizando 26 tipos de tubogotejadores diferentes, submetendo-os a diferentes concentrações (200, 300 e 400ppm) de carbonato de potássio via água de irrigação, com um tempo de 360h de irrigação. Os resultados mostraram que ocorreu uma significativa obstrução parcial e gradual para o modelo T1, se comparado com os outros modelos ensaiados. Os valores de vazão relativa em média obtiveram um coeficiente de variação de 7,91% no geral. E concluindo, o tratamento com ácido nítrico não foi satisfatório, devendo-se estudar uma melhor adequação do manejo deste produto. UNITERMOS: Vazão media, obstrução química, ácido nítrico  MEDEIROS, P.

F. de.DRIPPER CLOGGING DUE TO POTASSIUM CARBONATE APPLICATION  2 ABSTRACT             The objective of this experiment was to evaluate the clogging dynamics due to potassium carbonate application after nitric acid application in water irrigation. The test was performed in benches in the Hydraulics laboratory at ESALQ-USP, using 26 different types of drip lines and three different concentrations of potassium carbonate (200, 300 and 400 ppm) in irrigation water.  Irrigation time was 360 h. The results showed that a significant partial and gradual clogging in model T1 occurred when compared to other studied models. Relative flow values presented a variation coefficient of 7.91% in general, and the treatment with nitric acid was not satisfactory. New research should be carried out for this product better management. KEY WORDS: average outflow, chemical clogging, nitric acid.
