2013: Week 24 at the Source (Week 26 in the market)

Rain: The same weather pattern continued into week 24 at the source – very hot and dry days. The precipitation registered at our meteorological station was low – total of 15 mm (half inch) concentrated. Increased precipitation is expected next week as per our weather forecast.

Temperature: The air and soil temperatures remained very stable with only slight variations from the prior week. The average minimum air temperature was 23.6°C (74.4°F). The average air temperature was 27.6°C (81.6°F) and the average soil temperature remained stable at 28.2°C (82.8°F). The sunlight intensity was variable during the week but without extremes, while the relative humidity continued low for our tropical climate – 85.9 %.

Observations: Our climate remains stable and highly favorable to our land preparation and planting operations. During this transition time between the dry and wet season we must balance fruit quality, harvest volume, and crop age in order to avoid problems due to over/under mature fruit. As we endeavor to remain close to the optimum level, we are presently anticipating the initiation of an age reduction cycle that has a direct impact on brix and translucency. Additionally, we are currently in the peak of the natural fruit harvest and we recognize the need to keep a very strict control of our fruit’s age to achieve the right balance of sugar content and internal maturity.

2013: Week 23 at the Source (Week 25 in the market)

Rain: More of the same as there were very dry and hot days during week 23 at source. The precipitation registered at our meteorological station was almost nil (only 2.4 mm).

Temperature: The air and soil temperatures showed a very slight variation from the prior week. The average minimum air temperature was identical to last week at 23.2°C (73.7°F). The average air temperature was a bit higher at 28°C (82.4°F) and the average soil temperature remained stable at 28.1°C (82.6°F). Solar radiation was intense throughout the week, while relative humidity continued low and very similar to last week at 83.8 %.

Observations: Weather conditions remained optimal for a high-quality pineapple production period. Very sunny days, high air and soil temperatures, and very little rain continue to be our weather pattern. Our reliable weather forecasting service is predicting more of the same for the coming week.

2013: Week 22 at the Source (Week 24 in the market)

Rain: Dry and hot weather continued during week 22. We experienced one day of intense rain in the middle of the week and the rest was totally dry. The total precipitation registered was 22.8 mm (less than an inch).

Temperature: The air and soil temperatures were stable and without significant variation from prior week. The average minimum air temperature reached 23.2°C (73.8°F). The average temperature was 27.7°C (81.8°F) and the average soil temperature reached 27.9°C (82.2°F). Solar radiation was intense at the beginning of the week but normal during the rest; relative humidity continued low at 83.8 %.

Observations: Fortunately the start of the rainy season is delayed this year which is very positive for our operations, especially during this period of the year when we have a high volume of natural fruit. The quality is as good as it gets and the meteorological forecast continues positive for next week, so we do not anticipate any quality problems with our fruit.

2013: Week 21 at the Source (Week 23 in the market)

Rain: Week 21 at the source brought back some serious dry and hot weather. Except for a few days during the beginning of the week that registered precipitation of only 17.8 mm (close to 3/4 of an inch), the balance of the week was dry and sunny.

Temperature: The air and soil temperatures increased. The average minimum air temperature reached 23.5°C (74.3°F) – 0.8°C higher than last week. The average temperature also increased to 27.5°C (81.5°F) – 1.4°C higher than last week, and the average soil temperature increased to 27.7°C (81.8°F). Solar radiation was intense and relative humidity was identical to last week – 84.3 %.

Observations: There is no doubt that good weather conditions during this week and for the recent past, together with our conscious effort to increase harvest age, have played a significant role in the quality improvement that we see today. The percentage of NDF fruit being harvested is on the rise and will continue to be so for the next 6 weeks, but we are confident that our strict age control afforded by the colored ribbons will enable us to provide you with normal quality fruit during this usually challenging time frame.

2013: Week 20 at the Source (Week 22 in the market)

– Rain: Some very low intensity showers were recorded towards the end of Week #19 at the source. Total precipitation totaled 15.2 mm (0.60 inches) while dry and hot conditions prevailed.

– Temperature: Both the minimum and the average air temperatures dropped slightly during the week but the soil temperature remained stable. The average minimum air temperature reached 21.5°C (70.7°F) – 0.9°C lower than last week. The average temperature decreased to 26.9°C (80.4°F) but the average soil temperature continued stable at 27.4°C (81.4°F). Relative humidity continued low.

– Observations: The onset of a rainy period usually occurs by mid-May but seems to be delayed this year; a very positive turn of events because it will allow us to advance the many agricultural practices important to our crop and most importantly will allow us to continue to harvest the natural fruit with minimal quality concerns that are usually brought about by high precipitation.

2013: Week 18 at the Source (Week 20 in the market)

Rain: Dry and very hot conditions continued during week 18. Total precipitation was a mere 25.2 mm (1 inch), concentrated during the weekend so the rest of the week was incredibly dry!

Temperature: Both the minimum and the average air temperatures increased during the week but the soil temperature remained stable. The average minimum air temperature reached 22.4°C (72.4°F). The average temperature increased to 27.3°C (81.2°F) – 0.8°C higher than last week, but the average soil temperature continued stable at 27.3°C (81.1°F). Relative humidity was very stable at 84.3 % due to the low precipitation.

Observations: Weather conditions remained stable and well suited for the production of high quality fruit. Additionally, this is the period during which the farms take advantage of good weather and accelerate the process of soil preparation. The NDF harvest is taking place in a normal way and no quality problems are expected. A reliable source, who asked to be anonymous because they were not authorized to speak on the record, stated that volumes of Costa Rican pineapples will continue low and are expected to remain low over the next 8 to 10 weeks.

The Truth About Pineapple “Seeds”

Growers that cultivate pineapple often use the word “seed” for the sucker that is used for planting but this is the incorrect use of the word “seed”.  Pineapples do occasionally produce true tiny black seed just below the peel of the fruit which can be found when the fruit is peeled but, in general, pineapples are highly self-incompatible (a general name for several genetic mechanisms in angiosperms, which prevent self-fertilization and thus encourage outcrossing. In plants with SI, when a pollen grain produced in a plant reaches a stigma of the same plant or another plant with a similar genotype, the process of pollen germination, pollen tube growth, ovule fertilization, and embryo development is halted at one of its stages, and consequently no seeds are produced. SI is one of the most important means to prevent selfing and promote the generation of new genotypes in plants, and it is considered as one of the causes for the spread and success of the angiosperms on the earth).  Hummingbirds, when present, are the usual natural pollinators but most often when the pollen germinates on the female part of the flower known as the stigma, it usually does not grow through the style and fails to fertilize ovary.  Despite this self-incompatibility the fruit will still develop because pineapples are parthenocarpic which means the fruit goes ahead and develops without fertilization of the ovary.  Most fruits require fertilization for fruit development.  Another example of a parthenocarpic fruit is bananas.

The tiny black seeds that can be found occasionally can be grown into a pineapple plant but it is a very slow process.  I have grown them using two plastic glasses.  I put soil in one glass and place the seed on top of the soil and cover them with a very thin layer of soil and then carefully  moisten the soil (not to the point of saturation). I then invert the second clear plastic glass on tape it to the top of the glass with the soil to form a miniature greenhouse.  After 2-3 weeks you will see very small green leaves emerging from the soil.  It will take several months to obtain a plant large enough to plant into the ground or a large pot to eventually produce the fruit.

This time consuming process is the reason that commercial pineapple growers use suckers to plant in the field.  In a commercial operation, after the fruit is harvested some of the axillary buds that are at the base of every leaf of the pineapple plant will begin to develop into small pineapple suckers which will be large enough to plant in the field in a couple of months.  We incorrectly call these suckers “seed” they should probably really be called “daughters”.

  • The same precipitation pattern from prior week continues – heavy downpours during certain days of the week.
  • We struggle to increase age gradually, maintain acceptable internal quality and avoid water spotting and translucency brought by increased rainfall.
  • Much less NDF expected this year – industry wide hearsay is that there will not be a significant peak.
