Yield And Quality

In strawberry production, the combination of a high productive performance and fruits with desirable physicochemical characteristics requires the use of plants with a good quality and high initial vigor. This study aimed to evaluate the effect of plants with different crown diameters on the productive performance and fruit quality of strawberry plants of the cultivar ‘Pircinque’ (Short Day). The study was conducted in two evaluation cycles (2016/2017 and 2017/2018). The experimental design was divided into randomized blocks, with four repetitions, and plots consisting of 20 plants. This study evaluated the crown diameters of plants of 5, 7, 9, 11, 13, 15, 17, and 19 mm. The productivity and number of fruit values increased significantly by 57% with larger caliber plants, which also provided precocity of productivity. The use of more vigorous plants also favored the production of fruits with higher soluble solids/titratable acidity ratios (+28%) and with epidermis coloration closer to intense red (−4.3%). For the cultivar ‘Pircinque’, plant crown diameters between 15 and 17 mm are the most favorable because they condition the best productive performances in combination with precocity and a good fruit quality.

The use of shading screens of different colors can change the spectral quality of radiation and, as a consequence, the growth and production of crop plants. The aim of this study was to evaluate aspects of the growth, yield, and quality of floral stems of Heliconia psittacorum × H. spathocircinata ‘Golden Torch’ grown under different light conditions. The treatments consisted of four conditions: blue photoconversion screens (35%-40%); red photoconversion screens (18%-21%); black shading screens (45%-49%), and full sunlight. The experiment consisted of two parts. In the first, growth was assessed, whereas in the second, aspects related to the production and quality of floral stems were examined. The experimental design was in randomized blocks with split plots in time. Each plot contained six blocks, with 11 replications per block, giving a total of 66 pots per plot. The evaluations were performed at 30-day intervals over a 6-month period. In the analysis of growth, red screens contributed to the growth of the plants, increasing the number of shoots and leaves, and also plant height. The productivity and quality of floral stems was, however, highest in plants grown under blue and black screens. It can be concluded that, under the prevailing experimental conditions, the use of blue screens (35%-40%) and black screens (45%-49%) is suitable for production of the floral stems of ‘Golden Torch’ heliconia.

Objective: To compare the effect of earthworm humus (vermicompost) withrespect to that of a standard fertilization treatment with conventional chemicals onthe yield and fruit quality in the cultivation of habanero pepper (Capsicumchinense).Design / methodology / approach: The experimental design was of randomizedblocks with seven replicates. The treatments consisted of 100% worm humus, 50%worm humus + 50% soil combination, as well as soil with chemical fertilizers as acontrol. The number of fruits, the quality of the fruits (length, diameter, and weight)of three cuts (harvests), in addition to the yield per plant, were evaluated. The datawere analyzed with an analysis of variance and when statistical differences weredetected, a means comparison was performed with the Tukey test (P>0.05). 2Results: The 100% vermicompost treatment did not significantly reduce the heightand diameter of the plant stem. Regard yield, a 15% increase was observed,although it was not significant compared to the control. Likewise, the quality of thefruits did not decrease.Study limitations / implications: The combination of 50% vermicompost and soilor less could affect the development and yield of habanero pepper crops.Findings / conclusions: Supplying earthworm humus does not affect the yield orquality of habanero pepper fruits, which is an alternative for nutrients supply at lowcost which is also an environmentally friendly practice.

Sudden Decrease

Drought conditions in the western United States have limited water availability for the irrigation of agricultural products. This can have a dramatic impact on yield and quality of specialty perennial crops, such as juice grapes (Vitis labruscana Bailey). Washington State juice grape industry typically irrigates to 100% of crop-specific evapotranspiration (ETc) throughout the season to minimize yield loss. However, as conditions have limited water availability, growers need a new strategy to cope with the limited water supply. Regulated deficit irrigation (RDI) applies less water than plant ETc and has been shown to improve fruit quality in red wine grapes (Vitis vinifera). The objectives of this study were to evaluate the effects of RDI treatments on the yield and quality of ‘Concord’ juice grapes as compared with current commercial practice. The treatments reduced the amount of water applied between bloom and veraison by 25% (−25%), 33% (−33%), and 45% (−45%) from the control application. The results of this 4-year study initially indicated a dramatic decrease in yield in the −45% treatment (7.5 Mg/ha) as compared with the control treatment (19.2 Mg/ha); however, yield for the RDI treatments recovered in the subsequent seasons and was not statically different from the control. There were no statistical differences in fruit quality between treatments. This indicates that RDI has the potential to decrease water applied between bloom and veraison without impacting fruit quality; however, to avoid a sudden decrease in yield, it would be necessary to gradually reduce water applications over several years.

The study was carried out during summer of 2012 with BARI hybrid tomato 4, planted in the Olericulture farm of Bangladesh Agriculture Research Institute, Joydebpur, Gazipur, Bangladesh to find out the response of plants to some staking and pruning treatments on yield, fruit quality and cost of production. A two factor experiment consisting of three staking methods and four level of pruning, laid out in complete block design with three repetitions. Plants were staked on inverted „V? shaped staking, high platform and string. The plants were pruned to two stem, three stem, four stem and no pruning as control. Results showed that significantly the highest total number of fruits per plant (37.1), marketable fruits per plant (33.7), yield per plant (1.68 kg) and total yield (44.6 t/ha) were produced by the plants having the treatment string staking with four stem. The highest fruit set (43.50%) was found in the plants staking with string having three stems. Plants grown on string staking allowing two stem gave the maximum length (4.71 cm), diameter (4.83 cm) and weight (53.4g) of single fruit as well as maximum fruit firmness (3.43 kg-f cm-2). From the economic point of view, it was apparent that summer tomato produced by string staking with four stem pruning exhibited better performance compared to other treatment combinations in relation to net return and BCR (2.10).Bangladesh J.

The application of new technologies in precision agriculture offers the possibility to link information to very specific crop locations. The spatial representation of these agricultural data through yield and fruit quality maps allows for crop management in a precise way that means that agricultural operations may be carried out considering intraorchard variability, thus resulting in greater efficiency. The aim of this work was to advance the development of new tools for the generation of yield and quality maps for precision agriculture. A new tool was implemented for citrus through a dashboard called CitrusYield that integrates the requirements demanded by technicians and farmers in terms of spatial distribution and the quality of their citrus production. The data for testing were collected by a prototype of a citrus harvest-assist platform. In order to obtain maps showing heterogeneity of production, an experimental plot with different varieties and variable production was chosen. The maps, tables and graphs showing different crop data were generated automatically by CitrusYield from the analysis of the data collected. The main advantage of knowing the differences in production between the swaths and areas inside the crop is to provide the grower with precise information to make accurate decisions for localised crop management, such as fertilisation, irrigation, pest and disease control, etc.

 Alternate partial root-zone drying (PRD) irrigation and deficit irrigation (DI) are water-saving irrigation strategies. Here, comparative effects of PRD and DI on fruit quality of tomato (Solanum lycopersicum L.) were investigated. The results showed that the irrigation treatments had no effect on tomato yield but significantly affected several organic and mineral quality attributes of the fruits. Compared to DI, PRD significantly increased the fruit concentrations of Ca and Mg, and fruit juice concentrations of total soluble solid, glucose, fructose, citric and malic acid, P, K and Mg. It is concluded that PRD is better than DI in terms of improving fruit quality, and could be a promising management strategy for simultaneous increase of water use efficiency and fruit quality in tomatoes.

Comparison of the effect of two strains of mottle virus, two strains of veinbanding virus, and latent-A virus, alone and in combination, on vigor, yield and quality of British Sovereign strawberry plants grown under two planting systems showed: 1. Vigor was reduced by infection by a single virus and still further reduced by two viruses; 2. Yield was reduced by virus infection, especially during the first fruiting year when plants were grown under the hill system; 3. Fruit size was reduced only by virus combinations; 4. Fruit quality was affected only by veinbanding, which increased the total acid content and tended to reduce sugar content.
