Harvest Delay

A field study was conducted to examine the effects of various bunch covering and harvest delay combinations on the environment inside bunch covers, and on fruit yield and quality parameters. Treatments included the use of both unsealed and initially sealed (but often ultimately leaky) clear covers under the industry standard blue/silver cover, and the inclusion of an ethylene absorbent inside 'sealed' covers. The finger length, girth and weight of 'sealed' cover bunches that were harvested late were increased by up to 11, 13, and 37% respectively. Maturity bronzing increased with increasing delay of harvest of 'sealed' cover fruit. Greenlife was increased by the 'sealed' cover treatment, but decreased with increasing delay of harvest of 'sealed' cover bunches, and was increased by the presence of KMnO,. Greenlife was inversely related to finger size such that any treatment resulting in larger fruit tended also to reduce greenlife. The peel of ripe fruit from 'sealed' covers was greyer than that of the controls. Delaying harvesting increased the pulp to peel ratio of ripe fruit by 4%. The flavour of 'sealed' cover fruit was blander than that of their counterparts, with delay of harvest further reducing flavour. Up to about 40% of bunches were lost before harvest, due to snapped stems or to rotting of the bunch when the harvest of 'sealed' cover bunches was delayed during the warmer part of the year. Consequently, the yield of fruit with greenlife in excess of 10 days was as high from the standard treatment as from any of the more elaborate treatments. However, the 'sealed' cover treatment, when harvested at the normal time, produced the most fruit with a greenlife greater than 30 days.

Small Fruit

The market for small fruits (grapes, blueberries, strawberries, and raspberries) is valued at more than CAD100 million per year in Quebec, Canada. Wood-based biochar is an amendment that improves soil quality, which may boost small fruit growth and production. The objective of this research was to determine if wood-based biochar could increase the yield and quality of grape, blueberry, strawberry, and raspberry in southern Quebec. We evaluated the fruit yield as well as the quality parameters like average fruit weight, fruit firmness, color, juice pH, total soluble solids, total phenolic content, and antioxidant activity. Field trials were established on commercial farms with grape, blueberry, strawberry, and raspberry production systems in plots that received wood-based biochar and no biochar in spring (April to May). Small fruits were harvested at their ripening stage for yield and quality evaluation in fall (July to October). Biochar application did not improve yield and quality parameters of small fruits except it gave a marginal higher yield of grape (3.7 vs. 4.4 t ha-1, P = 0.08) and a higher average fruit weight of strawberry (11.9 vs. 13.2 g, P < 0.05). There was no difference in the quality of the fruit from biochar-amended and control plots in the first year of biochar application, possibly because the quality parameters are affected more by weather conditions, handling, and storage than by soil quality. This work suggests that wood-based biochar (<5 t ha-1) has a limited first-year impact on small fruit yield and quality in southern Quebec, Canada.

<em>Nutmeg has been known as native spices to Indonesia. The widespread cultivation of nutmeg cause the high demand for nutmeg seeds, hence the source of quality seeds is needed. The purpose of this study was to evaluate sex, morphological characters, yield and quality to be recommended as source of quality seeds. The research was conducted at Cicurug Experimental Station, Sukabumi (550 m asl).  The parameters observed were the sex of trees, and yield per tree harvested for nine years from 2007-2015. The quality was analyzed using Gas Chromatography Mass Spectra (GC-MS). The sex of the trees observations resulted 152 accessions (34.7 %) were pure males, 83 accessions (18.9 %) bisexual males and 203 accessions (46 %) pure females. Based on fruit yield, from 203 female nutmeg trees, 20 accessions produced high fruit yield &gt;2,500 fruits/tree/year. GC-MS analysis showed the number of identified compounds were 18-30 compounds with the main components were α-pinene, ß-pinene, sabinene, limonene, 4-terpineol, safrol, elemicin and myristicin. The 20 selected accessions met the quality standards for the essential oil, limonene and elemicin levels, but only five accessionsmet the standard quality for α-pinene, two accessions for ß-pinene, five accessions for sabinen, 18 accessions for 4-terpineol,  13  on  safrol,  and  11  accessions  for  myristicin  levels.  Tree  selected <em>accessions Botol 122, Irian 112 and Kupal 139 fulfilled nine out of ten quality parameters, whereas other accessions only fulfilled eight to four quality parameters. Accessions that achieved the criteria of fruit production should be recommended as source of quality seeds.</em></em>

In order to evaluate effect of leaf nutrients content at flowering and harvesting stages on fruit yield and quality parameters of guava a study was conducted on the orchards found in Jaipur,Ajmer and Sawai Madhopur districts of Rajasthan. According to this study all the leaf nutrients like nitrogen, phosphorus, potassium, iron, manganese, copper and zinc showed the positive correlationship with fruit quality parameters like total soluble solids, total sugars, total acidity, reducing sugar, ascorbic acid, fruit weight and fruit yield. At different age groups like less than 5, 5 to 15 and more than 15 years plant showed different plant nutrient adsorption level because plant root is not able to adsorb nutrients at early age as compare to middle age group plants like 5 to 15 years and at more than 15 years age plant is not much vigorous as young age group plants. To study effect of leaf nutrients at different age intervals like less than 5, 5 to 15 and more than 15 plant showed different extent of effect as nutrient uptake ability differ with age. In this study, more than 15 years age group orchards were found deficient in nitrogen, phosphorus and zinc whereas potassium, iron and manganese content were in optimum range at all the studied age groups. Maximum fruit yield was observed in 5 to 15 years age group orchards at Sawai Madhopur.

A field study was conducted to observe the effects of chemical fruit thinning and their time of application on fruit yield and quality of date palm cv. Khalas at Date Palm Research Center of Excellence, King Faisal University, Saudi Arabia. Fourteen date palm trees were randomly selected for the experiment, which was laid out on two-factorial randomized complete block design having six replicates for each treatment. Factor-one comprised of the six chemical (ammonium thiosulphate at 1, 2, and 3% and ethephon at 100, 200 and 300ppm) excluding control, whereas the second factor was the time of application of these two chemical thinners (5 and 10 days after pollination). The findings of this study indicated that the chemical fruit thinning had definite effects on virtually all fruit quality characteristics. Early application of chemical thinners after 5 days of pollination, significantly decreased the total fruits drop percentage and enhanced number of retained fruits, bunch weight, yield per palm, fruit color, fruit weight and length, seed weight, TSS, total and reducing sugars. On the other hand, among chemical thinners, the application of ethephon at 300 ppm significantly improved previously mentioned parameters. Similarly, ethephon at 200 or ATS at 3% also showed promising results. It is therefore, concluded that the application of ethephon at 200 or 300ppm after 5 days of pollination influenced significantly regarding fruit yield and quality parameters of date palm cv. Khalas.
