EM (effective microorganisms) is a biofertilizer consisting of a mixed culture of potentially beneficial microorganisms. In this study, we investigated the effects of EM treatment on leaf in vivo chlorophyll a fluorescence of photosystem II (PSII), yield, and macronutrient content of bean plants grown on different substrates (nutrient rich substrate vs. nutrient poor sandy soil) in controlled environmental conditions (pot experiment in greenhouse). EM-treated plants maintained optimum leaf photosynthetic efficiency two weeks longer than the control plants, and increased yield independent of substrate. The levels of seed nutritionally-relevant molecules (proteins, lipids, and starch) were only slightly modified, apart from the protein content, which increased in plants grown in sandy soil. Although EM can be considered a promising and environmentally friendly technology for sustainable agriculture, more studies are needed to elucidate the mechanism(s) of action of EM, as well as its efficacy under open field conditions.

Plant Densities

The performance of plantain fruit yield and quality under different planting densities under an influence of irrigation system was investigated at International Institute of Tropical Agriculture, Ibadan, Oyo State, Nigeria. Experiments were set up as a split plot fitted into randomized complete block design (RCBD) with three replications. Main plots are irrigation system while sub-plots are plant densities. Treatments included four plant densities (1 x 2, 2 x 2, 2 x 3, and 3 x 3 m), two irrigation systems and their combination where irrigation system was the main plot and plant density the sub-plot. Over 2,000 agbagba suckers were pared and hot–water treated, and planted during the first week of the experiment. Manure was applied at the rate of three spades full per plant for nutrient supplement; and mulching was done. Weeds were manually controlled as at when due. Plantain diseases like yellow sigatoka and black sigatoka were also controlled manually by de-leafing infected leaves to prevent disease spread. Data were collected and analyzed using ANOVA. Duncan multiple range test (DMRT) was used for mean separation at 5% level of significance. The results of ANOVA showed that there were significant effects (P < 0.05) due to irrigation application for all measured parameters whereas effects due to plant densities were significant for only these parameters; number of suckers (NOS), sucker height (SUHT), number of leaves on sucker (NLSC), bunch weight (BWT), number of hand (NHND), total number of finger (TFNG) and number of sucker at flowering (NSCK). Therefore, it can be concluded that plant spacing, and regular water supply plays a significant role in obtaining good yield in plantain production

Seedling Cold Tolerance

SummaryExotic accessions of Phaseolus vulgaris selected for seedling cold tolerance by Austin & Maclean (1972) in a test in controlled environments were grown in a field experiment at Wellesbourne in 1974. Yields of up to 4·;7 t/ha at a plant density of 34 plants/m2 were obtained. In 1975, six selected accessions were grown at 21 plants/m2 at six different sites. Mean site yields ranged from 1·0 to 3·1 t/ha. The six accessions all had better emergence and higher yields than two commercial cultivars used as controls. The genotype × site interactions for yield (and for yield components) were small. The variation in yield between accessions (from 2·0 to 2·5 t/ha) was smaller than the variation in yield between sites. Variation in yield components tended to be additive between sites, and compensatory between accessions. There was a negative correlation between crude protein content and yield across accessions; the correlation between protein content and yield across sites was not significant. Accessions differed significantly in the amount of green leaf still attached to plants at harvest. This variation was not related to maturity as judged by moisture content of the seed. There was a negative correlation across accessions between the weight of leaf per plant at harvest and harvest index (the ratio of seed weight to stem weight).

Os tratamentos constaram de diferentes níveis de cobertura morta com palhada de capim braquiária (Brachiaria decumbens), obedecendo delineamento experimental de blocos ao acaso com quatro repetições para os seguintes tratamentos: 0% (0 t/ha),  25% (2,25 t/ha),  50% (4,50 t/ha),  75% (6,75 t/ha)  e  100% (9,0 t/ha). O experimento foi conduzido na Embrapa Arroz e Feijão, no município de Santo Antonio de Goiás, GO, a 16° 28’ 00” de latitude sul, 49° 17’00”  de longitude oeste e 823 m de altitude, num Latossolo Vermelho escuro argiloso, durante o período de junho a setembro de 1997. O manejo da irrigação por microaspersão foi realizado utilizando tensiômetro e a curva característica de água no solo, irrigando toda vez que tensão matricial da água do solo atingia 30 kPa. A análise dos resultados mostrou  diminuição do número de irrigações e aumento do turno de rega nos tratamentos onde a cobertura  atingiu mais de 50% da superfície do solo. Os valores médios da tensão da água do solo nos tratamentos com 0,25 e 50% apresentaram maior variação (turno de rega menor). A cobertura do solo propiciou maior eficiência do uso da água.A produção de grãos foi avaliada não havendo diferença de produtividade entre os tratamentos de cobertura morta.  UNITERMOS: Cobertura do solo, Irrigação, Phaseolus vulgaris L.   PEREIRA, A.

E.   THE EFFECTS OF MULCH ON  IRRIGATION MANAGEMENT OF COMMON  BEAN (Phaseolus vulgaris L.)   2 ABSTRACT  The aim of this study was to evaluate the effects  of mulch on irrigation management of common bean (Phaseolus vulgaris L.). The randomized block design with four replications was applied on  five mulch rates: 0% (0 t/ha), 25% (2,25 t/ha), 50% (4,5 t/ha), 75% (6,75 t/ha) and 100% (9,0 t/ha).The study was set up at the Experimental Station of Embrapa – CNAF, Santo Antonio de Goias, 16°2’ south, 49° 17’ west and 820 m altitude from June to September, 1997 in a Dark – Red Latosol soil. A microsprinkle irrigation system was used.The results showed: - bean yield was not affected by mulch treatments; - the irrigation number was decreased when  mulch application was higher than 50%.   KEYWORDS: mulch, irrigation, Phaseolus vulgaris L.
