<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>

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.

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.

ABSTRACT The production of fruits and seeds of many crops is increased when bees visit their flowers pollinating them. The aim of this study was to evaluate the effect of different pollination treatments on ‘Bordô’ grapevine (Vitis labrusca L.) fruit quantity and quality. Quantitative and qualitative fruit production parameters of plants visited by Apis mellifera L., manually self- and cross-pollinated plants and plants without pollination were analyzed and compared. Fruit production was high for all treatments and all fruits presented four seeds per fruit, on average, confirming that this grape cultivar is autogamous. However, fruit set after spontaneous self-pollination was statistically lower than that of all other treatments, and pollination by A. mellifera showed the highest fruit production. Furthermore, pollination by honey bees resulted in increased biomass, reflected on fruit weight, but the content of soluble solids remained unchanged. The results of this study showed that there is no need of pollinators for fruit production of ‘Bordô’ cv., but the presence of these agents, in particular Apis mellifera, influences commercially important quality parameters such as fruit yield and fresh weight. Therefore, the use of bee hives in areas with deficit of pollinating insects may promote an improvement in yield and quality of this cultivar.

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.

Adverse Environmental Conditions

Apple accounts for more than 74 per cent of total fruit production in Himachal Pradesh. Poor fruit-set as well as heavy fruit drop due to improper pollination, moisture stress and adverse environmental conditions during flowering are the major barriers in dry temperate zone fruit production of apple. Apple tree blooms abundantly but only very few of them matures into fruit and it is the need of the hour to induce better fruiting with chemicals that ultimately augment the productivity. With such an intent the experiment was carried out. Nitrobenzene 20 % EW applied as a foliar treatment at three stages i.e. pink bud, petal fall and fruit setting stage. The highest number of fruits and flowers/plant was observed in T4 (3ml/liter) and T3 (2 ml/liter) of Nitrobenzene 20 % applied treatments. On the other hand the lowest number of flowers as well as fruits were recorded from T2 (1 ml/liter) and T1 (control). Among different treatments tested, 20% nitrobenzene applied at 3 ml/litre showed superior results in contrast to other nitrobenzene levels with enhancing flowering, fruit set, yield and quality.

High Calcium

Tomato (Lycopersicon esculentum Mill.) cv. Trust was grown in rockwool in summer and fall 1999 and 8 calcium/magnesium nutrient treatments, formed by two levels of calcium (Ca: 150 and 300 ppm) and four levels of magnesium (Mg: 20, 50, 80, and 110 ppm), were applied to investigate the effects on growth, fruit yield and quality. High calcium (300 ppm) increased overall fruit yield and size, reduced incidence of blossom-end rot and fruit cracking. However, high calcium also reduced the dry-matter content, soluble solid content and firmness of tomato fruit, and increased fruit russetting. Magnesium did not affect early growth or fruit production. However, 2 months after applying the treatments, the plants grown under 20 ppm Mg started to show Mg-deficient symptoms (leaf chlorosis), and Mg-deficient leaves lost more than 50% of their photosynthetic capability. The Mg concentration required for achieving high yield of firm fruit with high soluble solids and dry-matter content increased as the plant aged; i.e, 50 ppm in early stage of fruit production and 80 ppm in later stage of fruit production. At the end of experiment, the plants grown with 80 ppm of Mg also had the best root systems. Therefore, for both better yield and quality, a concentration of 300/50-80 ppm Ca/Mg may be recommended. Mg concentration may be started at 50 ppm and gradually be increased to 80 ppm in the later stage of fruit production.

The Impact

The goal of this study was to document the relationship between fruit growth patterns and flushing number in litchi (Litchi chinensis Sonn. cv. 73-S-20). The impact of flush number on fruit retention, fruit quality, and leaf efficiency (g fruit FW produced per unit of leaf area at harvest) was assessed in field-grown 6-year-old trees by adjusting the number of flushes per bearing shoot through girdling at two fruit developmental stages. The cumulative fruit growth was sigmoidal. The greatest fruit relative growth rate (RGR) occurred during 3 to 5 weeks after full bloom (AFB), peaking on week 3 at 0.39 g·g−1 dry weight (DW) per day. The greatest fruit absolute growth rate (AGR) occurred during weeks 8 to 11, peaking on week 11 at 0.16 g·d−1 DW. Fruit retention was sensitive to girdling applied during week 3. Most fruit dropped on branches with ≤ two flushes, whereas fruit continued to develop on branches with three flushes and on the controls. There was a gradual loss of fruit when the girdling was applied during week 8. The number of fruit retained on branches with two and three flushes was similar to the controls. At harvest, regardless of the time of branch girdling, fruit yield and quality increased with increasing number of flushes; shoots with three flushes were similar to ungirdled controls. Leaf efficiency on branches girdled during week 3 was inferior to that girdled during week 8. All treatments had similar leaf efficiency when branches were girdled during week 8. On the other hand, girdling treatment applied during week 3 resulted in variable leaf efficiency among treatment, indicating that fruit were utilizing reserves in bearing shoots. We concluded that bearing shoots of ‘73-S-20’ litchi trees require a minimum number of three flushes for adequate fruit production.
