Irrigation and fertilizer are the most dominating factors, in deciding the keeping quality of potato. It is, therefore, essential to formulate the efficient, reliable and economically viable irrigation management strategy with the use of potassium nutrient in order to produce better keeping quality. The investigation comprising four levels of irrigation (25, 30, 35 and 40 mm CPE (Cumulative pan evaporation) and four levels of potash (0, 100, 125 and 150 kg/ha) was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, (Haryana) Hisar, India during two years to find out the optimum level of irrigation and potash for obtaining higher yield of potatoes with better keeping quality at ambient room temperature. The potato variety used for the investigation was Kufri Bahar. The treatments were laid out in a split plot design with three replications. The increasing levels of irrigation and potash showed significant improvement in keeping quality parameters of potato. Likewise, the values for physiological loss in weight and decay loss of potato tubers (%) at 15, 30, 45 and 60 days after harvest were the lowest with irrigation level 40 mm CPE and application of potash @ 150 kg/ha. The two years results suggest that the irrigation level 40 mm CPE along with potash @ 150 kg/ha has shown the best treatment combination for the storage of potato at ambient room temperature under semiarid conditions of Hisar (Haryana).

Keberhasilan kegiatan budidaya perikanan harus ditunjang dengan ketersediaan benih yang berkesinambungan. Oleh karena itu, diperlukan juga ketersediaan pakan alami larva berupa rotifera (Brachionus rotundiformis). Desain percobaan berupa rancangan faktorial dengan dua faktor dan lima ulangan diaplikasikan dalam penelitian ini. Sebagai perlakuan berupa suhu ruang penyimpanan (suhu kamar, suhu ruang AC, dan suhu refrigerator/lemari es) dan pakan mikroalga konsentrat (monospesies dan multispesies). Bakteri probiotik juga digunakan sebagai pengontrol kualitas air. Spesies mikroalga yang digunakan adalah Nannochloropsis sp., Dunaliella sp., Isochrysis sp., dan Pavlova sp. Parameter yang diukur adalah kelimpahan rotifera dan parameter kualitas air media kultur (pH, salinitas, DO, dan NH3). Analisis data terdiri atas analisis regresi, analisis ragam, dan uji keparalelan. Hasil pengukuran parameter kualitas air selama penyimpanan menunjukkan kondisi media yang relatif stabil dan merupakan kisaran optimum bagi pertumbuhan B. rotundiformis. Kelimpahan maksimum tertinggi dari B. rotundiformis baik pada perlakuan pakan monospesies maupun multispesies alga adalah pada suhu kamar. Dari interaksi kedua perlakuan, diperoleh kelimpahan akhir tertinggi pada suhu ruang AC–pakan multispesies. Hal ini menunjukkan bahwa rotifera dapat disimpan lebih lama pada suhu ruang AC dengan pemberian pakan multispesies alga.The success of any aquaculture practices should be supported by sustainable supply of fish fry. Therefore, the availability of rotifers (Brachionus rotundiformis) as natural feed for fish larvae is required. The research was arranged in factorial design with two treatments and five replications. Treatments consisted of different room storage temperatures (refrigerator, room temperature, and room with air conditioner/AC) and microalgae concentrate added as rotifer feed (monospecies and multispecies algae). Probiotic bacteria was used to control water quality. Mikroalgae species consisted of Nannochloropsis sp., Dunaliella sp., Isochrysis sp., and Pavlova sp. Parameters measured were rotifer density and water quality of rotifer media (pH, salinity, DO, and NH3). Data analysis included regression analysis, analysis of varians and parallel testing. The results of water quality parameters during rotifer storage showed that media conditions were relatively stable and optimal for B. rotundiformis growth. The result of treatments interaction showed that the highest maximum density of rotifer at the end of the research was achieved by rotifer stored in air conditioned room fed with multispecies algae. This showed that rotifers can be stored longer in room storage with AC and fed by multispecies algae.

Four different types of Dahi (Yogurt) were prepared and kept at room and   refrigeration temperatures with different concentrations of potato mash (0, 5, 10 and 15%). These Dahi samples were analyzed for smell and taste, body and consistency, colour, texture and acidity and pH at pre and post storage period. The quality of Dahi deteriorated quickly at room temperature than at refrigeration temperature. With (5%) or without potato mash keeping quality was preserved for up to three days but at refrigeration temperature they were suitable up to 12 days. Addition of 10% and 15% potato mashes were suitable for keeping Dahi up to two days at room temperature while in refrigeration temperature it was acceptable up to ten and eight days, respectively. Preparation of Dahi in incorporating potato mash may be economically feasible without compromising it qualities. DOI: http://dx.doi.org/10.3329/bvet.v29i1.11886 Bangl. vet. 2012.

The work was conducted on sunflower seeds of two cultivars namely ‘Kironi’ and ‘Hysun-46’. Proximate composition of the seeds, chemical characteristics and fatty acid composition of the oils, and its keeping quality at different storage conditions were studied. Moisture content of Kironi seeds was nearly twice than Hysun-46 (8.03 vs 4.46%). Crude fat in Hysun-46 seeds was somewhat higher than Kironi. Kironi had significantly higher crude protein whereas Hysun-46 contained significantly higher percent of starch than Kironi (7.05 vs 3.90%). Physical characteristics of oil such as viscosity, colour and transparency changed with time during storage; specific gravity and smoking temperature, however, remained unchanged. Acid values of the freshly extracted oil from Hysun-46 were unexpectedly high (98.75). Iodine values were found to be higher in Kironi than Hysun-46, so the former had greater proportion of unsaturation. Saponification values of the oils decreased with the time in open vessel, in amber coloured bottle at 4°C and also in boiled oil kept at room temperature. However, these values registered an increase in oils stored in closed vessel and amber coloured bottle at room temperature. Peroxide values increased in oils under all conditions except in amber bottle at 4°C. The ratio of linoleic acid to oleic acid in Kironi (2.3:1) was higher than that in Hysun-46 (1.9:1), indicating that Kironi had more semidrying capacity and suitable for edible purpose. The freshly extracted oil had attractive appearance. Between the two oil samples, Kironi seems somewhat superior to Hysun-46.

AbstractInhibiting sprouting of potatoes is an interesting subject needed for potato storage and industry. Sprouting degrades the quality of tuber along with releasing α-solanine and α-chaconine, which are harmful for health. Sprout suppressants, available in the market, are either costly or toxic to both health and environment. So, there is a need for developing countries to explore new sprouting suppressant compound which is cheap, non-toxic and reasonably efficient in comparison to commercial ones. We have established that simple maleic acid and l-tartaric acid are effective sprout suppressing agents. Both can hinder sprouting up to 6 weeks and 4 weeks post treatment respectively at room temperature in dark. These do not affect the quality parameters, retain the moisture content and maintain the stout appearance of the tubers along the total storage period. Thus maleic acid and l-tartaric acid would qualify as alternative, cheap, efficient sprout suppressant for potato storage and processing.

ABSTRACT The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

ABSTRACT Water management and meteorological conditions during the cropping phase play an essential role in maintaining the commercial quality of cut flowers. This study evaluates water requirement, sensitivity to water deficit, and commercial quality of gladiolus ‘Amsterdam’ produced with automated irrigation in different growing periods. The experimental design was in randomized blocks with five replicates and consisted of the growing period factors (winter/spring 2018 and autumn/winter 2019) and the irrigation level factors (45% - L1, 60% - L2, 80% - L3, and 100% - L4 of crop water requirement). An automatic irrigation controller was used for irrigation management. At the harvest point, we evaluated the stems for the diameter, number of flowers, spike length, and floral stem length. We also evaluated stomatal conductance, leaf area, and duration of phenological phases on degree-days. The application of 100% crop water requirement using an automatic irrigation controller in the autumn/winter cycle results in better commercial classification. The treatment with 45% of the crop water requirement extended the total duration of the cycle. In conclusion, flower stems of better commercial classification are obtained with 100% of crop water requirement during the autumn/winter cycle.

OIL QUALITY OF JATROPHA TREE CULTIVATED UNDER DIFFERENT MANAGEMENTS OF IRRIGATION AND POTASSIUM FERTILIZATION     2 ABSTRACT   Jatropha is an oilseed with high potential for biodiesel and biofuel production. However, studies are scarce about the effect of water and nutritional requirement in the oil quality and composition. Therefore, the objective of this work was to evaluate the effect of potassium fertilization and irrigation on the composition of jatropha oil. The treatments consisted of four potassium fertilization levels: 40, 80, 120, and 160 kg ha-1, and four irrigation levels: 0% (without irrigation), 40%, 80% and 120% of Class A pan evaporation (ECA). The experimental was design in randomized blocks with subdivided plots and four replicates. The mechanical method by pressing was used to extract oil from the seeds, using gas chromatography to obtain the oil composition. Fertilization and irrigation treatments promoted changes in the quality of jatropha seeds oil. Plants fertilized with 120 kg ha-1 of K2O and with  irrigation level of 80% of ECA show the best results.   Keywords: biodiesel, irrigation management, plant nutrition, Jatropha curcas.

A study was carried out to find out the effect of silica gel on keeping quality of tea. CTC-SRD grade teas each at 250 g were packed in low density poly ethylene pouches with a small pouch containing silica gel (10 g). Another set of samples were packed in low density poly ethylene packing material without silica gel. From sealed pouches, every month one pouch was taken and analysed for their moisture and quality parameters such as theaflavin, thearubigin, high polymerised substance, total liquor colour and biochemical parameters such as total polyphenol, total catechin, water extract and amino acid. Studies conducted after fourteen month indicated that the moisture content increased in teas packed in LDPE alone and it was less in teas packed in LDPE with silica gel. The level of theaflavin content decreased by 24.01% in teas packed LDPE alone and 17.92 % in LDPE with silica gel respectively. Bio chemical parameters decreased in teas packed in LDPE when compared to LDPE with silica gel. The study reveals that silica gel is useful in maintaining the keeping quality of tea.
