The effects of added limestone and potassium on the yield of cabbage (Brassica oleracea L. var. capitata) were investigated at different locations each year for three consecutive years. The cultivars, Excel, Green Winter and Houston Evergreen were grown at each location and after harvest were held for 5 mo in storages maintained at about 2 °C and 95% RH and at about 6 °C and 90% RH. An application of dolomitic limestone at 6.7 t/ha, prior to transplanting, on soils with pH levels of 4.8–5.4 increased marketable yields. The addition of potassium at 224 kg/ha compared to 56 kg/ha also increased yields. The lime treatment reduced the percent weight loss due to dehydration in storage, but neither the lime nor the potassium treatment had any significant effect on the proportion of the original weight placed in storage that remained in marketable condition.Key words: Cabbage, Brassica oleracea, cold storage, lime, potassium, fertilizer

SUMMARYOver five growing seasons (1976–80) experiments were carried out using at least three contrasting sites per season to study the relationship between growing conditions and storage losses in Pentland Crown potatoes. Crops were harvested by hand and storage was carried out in a single environment over a period of 6–7 months without sprout suppressants. The range in growing conditions was great and reflected in the pattern of leaf growth and range in yields of the stored crops (30–90 t/ha). Crops from Tenby (S. W. Wales) produced the most consistent and frequently the highest yields and usually lost the least weight during storage. Although the range in total weight loss over all experiments was large from 5·4 to 16·3%, treatment effects were much smaller than in field growth and yield. Delaying the date of harvest usually increased weight loss and tubers harvested in early August stored at least as well as late-harvested tubers. Tubers harvested without prior defoliation stored as well as tubers harvested on the same day from crops defoliated at least 2 weeks previously. Lengthening the interval from defoliation to harvest usually increased weight loss in storage. Although the tubers were hand harvested effects on saleability were found at the end of storage and there was no evidence that earlier harvesting, which may involve some loss of field yield, would result in any loss of saleable yield out of store.The results provided no evidence to support the widely-held view that the suitability of a tuber for harvesting improves during maturation associated with natural or imposed crop senescence. It is therefore suggested that the use of the term maturity be avoided as it is wholly unhelpful in studies of the relationship between field growth and storage losses in potatoes.

Bulb Yield

Bulb yield and storability of onions (cv. BARI Piaj-1) was studied against five levels of irrigation viz., no irrigation, irrigation at 10, 15, 20, and 30 days interval. Yield and storage losses were increased gradually with increasing number of irrigation. The highest yield of onion was obtained with a total of six irrigations at 10 days interval and it was at par with treatment that received four irrigations at 15 days intervals. Losses due to rotting, sprouting, and physiological weight loss were found higher in irrigated treatments. After six months of storage (from 1st week of April to 1st week of October), the maximum cumulative weight loss (56.72%) was recorded in onions irrigated at 10 days interval, while the minimum (46.80%) was recorded in non-irrigated onions.

<p>Bawang merah merupakan salah satu jenis komoditas yang menjadi kebutuhan masyarakat. Namun bawang merah sangat mudah mengalami perubahan mutu seperti susut bobot, perubahan volatile dan mengalami kerusakan karena memiliki kandungan air yang tinggi, sehingga diperlukan metode penyimpanan yang baik untuk mempertahankan kesegarannya selama penyimpanan. Salah satu cara untuk mempertahankan kesegaran dan kualitas bawang merah adalah menyimpan pada suhu rendah dengan tingkat kadar air tertentu. Adapun tujuan dari penelitian ini untuk mengetahui tingkat kadar air dan suhu penyimpanan yang mempertahankan mutu bawang merah konsumsi, serta pendugaan mutu bawang merah hingga penyimpanan 6 bulan. Bawang merah dikeringkan hingga kadar air mencapai 85% dan 80% kemudian dimasukkan kedalam kemasan rajut masing-masing sebanyak 2 kg dan dilakukan penyimpanan pada suhu 5°C dengan RH 65-70%, 10°C dengan RH 65-70% dan suhu ruang (25-30°C) dengan RH 52-88% selama 8 minggu. Dari hasil penelitian menunjukkan bahwa penyimpanan bawang merah yang terbaik pada kadar air 80% dengan suhu 5°C RH 65-70%, menghasilkan susut bobot 7,06%, kadar air 79,48%, kerusakan 0,37%, kekerasan 4,38 N, dan VRS 26,53 ?Eq/g.

But shallots are very susceptible to changes in quality such as weight loss, changes in the volatile and damaged because it has a high water content, so it needed a good storage method for maintaining freshness during storage. One way to maintain the freshness and quality of shallot is storing at low temperatures with a certain level of water content. The aim of this study was to determine the level of water content and storage temperature to maintain the quality of shallot consumption, and shallot estimation quality until 6 months of storage. Shallots were dried to water content reached 85% and 80% and then inserted into the knited packaging each of 2 kg and then stored at 5°C with RH 65-70%, 10°C with RH 65-70% and room temperature (25-30°C) with RH 52-88% for 8 weeks. The result of the experiment showed that storage of shallot in water content of 80% at 5°C RH 65-70%, resulting in a weight loss of 7,06%, the water content of 79.48%, disorder 0,37%, hardness 4,18 N and VRS 26.53 ?Eq / g.

`Bartlett' pears were harvested from four commercial orchards at their optimum harvest date and 3 or 7 days later (depending on grower orchard). Samples were held for 3 or 7 days before stored in cold storage and two controlled-atmosphere conditions: 1) cold storage at 1C; 2) regular CA storage (2.5% O2 + 1.0% CO2 at –1C); 3) low-oxygen CA (1.0% O2 + 0.2% CO2 at –1C). After 2 months of cold and CA storage, pears showed that postharvest prestorage holding temperature, affected the rate of change in weight loss, firmness, ground color, and senescent breakdown. After 4 months of CA storage, `Bartlett' pears maintained their quality at about 53–58 N of firmness. Firmness loss, peel ground color change, and senescent breakdown of `Bartlett' pears were affected by the holding temperature and the length of the holding period between harvest and storage. In conclusion, pear quality was reduced depending on the holding temperature and holding period between harvest and storage. CA storage maintained better pear quality than cold storage. Fast oxygen pulldown in order to establish CA condition sooner was essential to maintain better pear quality.
