It was observed that some varieties have preference, if not luxurious consumption for specific elements. Among the varieties, Phil 7495 and Phil 7779, a low tillering variety required less amount of nutrient to maintain normal biomass production. While Phil 56226, a high tillering variety required higher N, K, and Mg at six months compared to other varieties. Root mass was not significantly associated with nutrient uptake in this study which leads to conclude that root mass is not the main contributing factor to nutrient absorption. Nutrient uptake as of these findings is still not a good index for determining biomass yield at harvest

Phil 7115, Phil 7083, Phil 56226, Phil 7495, Phil 6723, Phil 6553 and Phil 6607 gave significant differences on nutrient composition on the leaf blade, leaf sheath, bagasse and juice. The juices of Phil 56226 and Phil 7495 showed significantly higher phosporus content compared with the other varieties. The nutrient content of the juice was not significantly correlated with rendement. Estimates of the amount of nutrient uptake are presented

Name brand frozen pot pies are evaluated for taste, calories, sodium, cost, taste and texture. Beef, chicken, turkey and vegetable varieties are rated. General information is provided on the nutrient content of pot pies.

Breeding for genetic tolerance to soil Al stress requires an effective screening method to distinguish between tolerant and susceptible genotypes. Field studies to evaluate corn (Zea mays L.) populations for tolerance to aluminum toxicity were carried out in tropical acid soils, in Colombia, South America. Fifty varieties were grown at four sites which differed in soil aluminum saturation. A block-in-replications design with five replication was used in the experiments. Field response variables of the varieties and two other sets of materials were correlated with variables in the solution method based on genotype means. Genetic variability existed among varieties tested. Increased Al stress appeared to be related to delayed maturity, increased ear rot percentage, poor plant vigor, ear aspect, and reduced yield. Plant vigor score was a good indicator for selecting aluminum tolerance during the growing period. Yield relative to the mean of the ten best entries was the best parameter among relative values. However, the actual yield would give the same predicted gain as the relative yield would. Significant correlations were found between the results from nutrient solutions and field growth parameters when the material were grown in the highest Al stress. The responses from the nutrient solution method involving root growth in Al stress solutions did not always correlate with the responses when grown on acid soils.

Japan is one of the major countries that produce strawberry, next to the United States. Since the end of the nineteenth century, many varieties have been introduced from the United States or Europe, and Japan itself has released a large number of new varieties by crossing the foreign ones. The most popular cropping type here is forcing culture, in which plants with flower buds are transplanted in vinyl houses and harvested from the beginning of December to April in the following year. In forcing culture it is important to induce flower buds at the proper time and to continue harvesting. Various techniques such as low temperature treatment for flower bud induction, CO2 application for continuous harvesting and nutrient film technique for easing the farmer's work have been developed. The first new variety developed in Japan is "Fukuba", which was released in 1899. This variety has been cultivated for almost fifty years and used many times as parents. After World War II, public agricultural experimental stations bred new varieties for the fresh market consumption. Among them "Hokowase", "Harunoka" and "Reiko" had been leading varieties until a few years ago. But recently the new varieties, "Nyoho" and "Toyonaka", have overtaken them due to their improved marketable characteristics

Twenty years ago we investigated the nutrition status and determined standard and critical values of nutrient elements in the leaves of apple and some stone fruit trees. For this purpose leaf samples were collected from high productive orchards situated in different soil and climatic zones of Czechoslovakia, from trees without symptoms of nutrient deficiency. These studies demonstrate that the nutrient element distribution can be related to the nutrient status. The results obtained are utilized by Agricultural Test Laboratories and by fruit growers. Simultaneously we have evaluated the relation between fruit production and changes of leaf nutrient contents. The relation between soil management, migration of N, P, K, Ca and Mg into lower layers and their content in the leaves of five apple varieties was followed under two various climatic and soil conditions. A close correlation was found between the content of NO3 in the soil and the yield. The level of nitrogen in leaves was highest in the herbicide treated plots and the lowest in plots with grass and cultivation. Phosphorus content was highest in the herbicide and grass plots. Potassium and Mg contents were highest in the plots with mulch followed by grass and herbicide treated plots. A method for calculation of nutrient doses was developed on the base of the mineral content in leaves and the expected yield.

Zygotic embryos of Carica papaya were successfully germinated in vitro on Murashige and Skoog's medium supplemented with 2% activated charcoal. The effects of light, temperature, sucrose and nutrient concentrations in the medium, on growth and development of embryos were examined. Strength of the nutrients in the medium had no effect on the growth and development of embryos. The germinated embryos of different varieties of papaya were inoculated using a sporangial suspension of different isolates of Phytophthora palmivora. In the analysis of variance, varieties, isolates and variety—isolate interactions differed significantly. The results were compared with the inoculation of glasshouse-grown seedlings; it is suggested that embryo inoculation could be a useful method of detecting resistance at an early stage of plant development.

The effects of various fertilizers on three red beet varieties were investigated in this trial. It was observed that, in this case, the yield did not depend upon the variety characteristic but upon the type of fertilization applied. It was not observed that there was any causality between the realized yield and the chemical composition of red beet roots. It was found out, however that the ratio between the mineral matter of a ram red beet and daily nutrient requirements of a human organism are as follows; there are 2.5 times more potassium and sodium in a red beet, 1.5 times more phosphorous, 4 times more iron, about 40% more calcium, about 50% more magnesium and 60% more copper than it is sufficient to meet the maximum nutrient requirements of a human organism per day.
