[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city. A field experiment was arranged in a randomized complete block design (RCBD) with 3 replications for alloting two factorial treatments structure, namely rates of fruit thinning (no fruit thinning, thinned to one fruit /plant, thinned to two fruits/plant, and thinned to three fruits/plant) and rates of NPK fertilizer application (400, 600, and 800 kg/ha) on rhe experimental plots. The results showed that fruit thinnings resulted no increament in crop productivity, but the fruit quality was improved as fewer number of fruits were retained on each plant. The NPK fertilizer at 400, 600, and 800 kg/ha were not able to increase the productivity of cantaloupe  and the quality of the  produced fruit when  the application were made only at planting and 23 days after planting.

ABSTRACT Mechanizing the harvest of Jalapeño pepper involves changes in the production system. Spacings between plants in rows (10 to 40 cm; 60 cm fixed between rows) were evaluated in relation to plant architecture, productivity and fruit quality of cultivar BRS Sarakura during three years, in a randomized complete block design with five replicates. Productivity (41.9 to 78.8 t ha-1) and plant height (40.1 to 47.3 cm) responded linearly to density; on the other hand, productivity per plant responded negatively (0.48 to 1.04 kg plant-1). The stem first bifurcation height was little influenced. Fruit chemical analyses were carried out in the second year of the experiment; spacing significantly influenced pH (5.36 to 4.84), total titratable acidity (TTA) (0.48 to 0.36%) and total soluble solids (TSS)/TTA ratio (11.5 to 15.6); no influence on TSS (5.65%) was noticed, though. The increase of plant population provided an increase in productivity without affecting fruit quality; the highest height of the first bifurcation achieved may not be enough to enable mechanized harvesting of the cultivar BRS Sarakura.

Extending the planting area to a less-fertile soil, such as Ultisols, become inevitable choice to increase the national chili pepper production in Indonesia as this types of soil is the largest part of dry land of Indonesia, about 29.7% or around 51 million ha.  However, efforts to increase its productivity by providing sufficient fertilizers application is most frequently inefficient because in the conventional fertilizer applications, broadcasted fertilizer on the soil bed, are not readily available for the plant as their solubility is limited under the plastic mulch and still in the form of granular until the end of planting season.  Fertigation, therefore, maybe the answer for this problem.  The objective of this study was to determine the best NPK fertigation method on four chili pepper hybrids.  The experiment was conducted in a randomized complete block design with three replication, and the treatments were arranged in a split plot design.  As the main plots were NPK fertigation intensity, i.e. 100%, 75%, 50%, 25% and 0% fertigation with the remnant fertilizers were circularly broadcasted surrounding the plant.  As the subplots were chili pepper hybrids, i.e. ‘Maxima’, H39, H14, and ‘UNIB CHR17’.  The results showed that there was no interaction effect of fertigation intensity indicated that all hybrid genotypes showed similar pattern of responses.  The H39 hybrid had better vegetative growth compared to other hybrids in term of plant height, dichotomous height, stem diameter, number of branches, plant fresh-weight.  Whereas the hybrid cultivar ‘Maxima’ showed the highest yield followed by H14 and cultivar ‘UNIB CHR17’.  The 100% fertigation was the best method of NPK fertilizer application for chili pepper in Ultisols.keywowrd: fertigation, chili pepper, fertilizer application, acidic soil

Effects of chemical thinners on yield, fruit size, and fruit quality was studied in a commercial orchard in Milton, N.Y., on 6-year-old `Honeycrisp'/M.26 trees. The trees were planted at 1.8 × 3.6-m spacing with trickle irrigation and were trained to the vertical axis system. The treatments applied in a randomized complete-block design with four replications were an untreated control; carbaryl (Sevin XLR at 125 mL/100 L); NAA at 2.5 ppm, 5 ppm, or 7.5 ppm; NAA at 2.5 or 5 ppm plus carbaryl; and Accel (a.i. at 74 g·ha-1) plus carbaryl. Chemical thinners were applied to drip with an air-blast sprayer, when the largest fruit were 11.5 mm in diameter. Generally, thinning activity increased with increasing NAA concentration. The combination sprays of 5 ppm NAA plus carbaryl, and Accel plus carbaryl over-thinned `Honeycrisp'. Carbaryl alone was inconsistent. All thinning treatments increased fruit size relative to unthinned trees, with average fruit diameter exceeding 76 mm. `Honeycrisp' is a large-fruited cultivar that is easy to thin chemically at the traditional 10- to 12-mm growth stage. NAA at 2.5 or 5 ppm provided adequate thinning to produce fruit of good quality and size. If initial set is heavy and a stronger thinning response is desired, the combination of 2.5 ppm NAA plus carbaryl could be used. `Honeycrisp' appears to be very sensitive to Accel, when used in combination with Sevin XLR. Further research needed before Accel is used to thin `Honeycrisp'.

<p>The fruit thinning process is employed for the production of high quality large-sized fruits and prevent the production of compact bunches. It is also one way to reduce the alternate bearing habits in date palm. In this study, seven thinning treatments (i.e. without spraying water after pollination, spraying water at 3 minutes after 3, 4 and 5 h, spraying Ethephon at 0, 500 and 1000 ppm after ten days from pollination) are used for Khalas and Ruzeiz date palm cultivars. The factorial experiment in a randomized completely block design with three replicates was done. The results reveal that, spraying water after mechanical pollination has reduced fruit set% and increased fruit shees%. Most thinning treatments reduced fruit yield/palm in both Khalas and Ruzeiz. Spraying water after 5 h enhanced fruit quality compared with the other thinning treatments in besr and tamr stages. Spraying with ethephon at 1000 ppm gave the increased sugars content and TSS, whereas reduced the moisture content in besr stage. Spraying water after 5 h from mechanical pollination or Ethephon at 1000 ppm after 10 days are suitable for obtaining economic yield with best fruit quality.</p>

The Tropics

Cultivation of okra (Abelmoschus esculentus L.) which is a commonly grown vegetable crop in the tropics is constrained by depleting soil fertility. Use of foliar fertilizer as a supplement has been successfully reported in the temperate region hence there is need to determine the effect of foliar liquid fertilizer on okra growth and nutritional quality. Field experiments were conducted at the Abeokuta (Federal University of Agriculture [FUNAAB] ) and Ibadan (National Horticulture Research Institute [NIHORT] ), between May and August 2015 to evaluate the response of two okra varieties to types and rates of organic-based foliar fertilizer application. Experiment was a 2 × 2 × 5 factorial combinations laid out in Randomized Complete Block Design with three replicates at both locations. Factors were okra variety (LD88 and NHae47-4), the fertilizer types (D.I. Grow Green ® and D.I.Grow Red®) and four rate of foliar applications (0 [control], 300, 600 and 900 ml/ha) while NPK 15:15:15 served as check. The results showed that the D.I.Grow Red® at 300ml/ha produced the higher Ash (8.23%), fat (2.54%,), moisture (14.65%),  and carbohydrate (47.31%)  at Abeokuta while 600 ml/ha produced significantly the higher ash, crude fibre, moisture and carbohydrate (9.37%, 15.94%, 9.13%, and 52.02%), respectively in Ibadan. The study concluded that okra variety LD88 had superior growth performance. Application of D.I.Grow Red® at the rate of 300 ml/ha at Abeokuta and 600 ml/ha at Ibadan enhance fruit nutritional quality of okra. Therefore, 300 and 600 ml/ha is recommended to farmers in Abeokuta and Ibadan, respectively.

Bell pepper is very susceptible to Phytophthora capsici, therefore the use of rootstocks can be useful to reduce the incidence of root diseases and to increase and improve fruit quality and its chemical composition. The objective of the present study was to evaluate the effect of commercial rootstock “Terrano” on the quality and the accumulation of organic elements in the leaf, peduncle, and pulp of bell pepper (Capsicum annuum L.). The work was carried out in a mesh shade system in Delicias, Chihuahua, Mexico during the production cycle of 2012, with an experimental 2x2 factorial design in a randomized complete block design where the a) factor was the cultivar: Fascinato and Janette, while factor b) was the use of rootstock “Terrano” (grafted and ungrafted), giving four treatments: Fascinato/Terrano, Fascinato/ungrafted, Janette/Terrano, and Janette/ungrafted. The accumulation of organic elements: nitrogen (N), sulfur (S), hydrogen (H), carbon (C), proteins, as well as the quality of bell pepper (firmness, color, and weight) were evaluated. The results indicate that there were statistically significant differences due to the effect of the rootstock on the studied cultivars (Fascinato and Janette), where the rootstock “Terrano” increased the accumulation of organic elements: N, S, and protein in leaf and pulp of the cultivar Janette; in addition, the weight of the fruit increased. The use of commercial rootstock “Terrano” could be a viable technique to improve the accumulation of organic elements as well as the quality of bell pepper in cultivars Fascinato and Janette.

A field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during Aman season of 2011 to evaluate the effects of manures and fertilizers for maximizing the yield of BRRI dhan49. The experiment had six treatments, laid out in a randomized complete block design (RCBD) with four replications. The treatments were T0 = Control, T1 = STB-CF (HYG), T2 = CD + STB-CF (HYG), T3 = PM + STB-CF (HYG), T4= CoM + STB-CF (HYG) and T5 = Farmers’ practice (FP). Organic manures including cowdung, poultry manure and compost were applied to the experimental plots @ 5, 3 and 5 t ha-1, respectively. The recommended dozes of N, P, K and S supplied from urea, TSP, MoP and gypsum were 90, 15, 60 and 15 kg ha-1, respectively. Yield contributing characters like plant height, effective tillers hill-1, panicle length and grains panicle-1 of BRRI dhan49 were significantly influenced by the application of manures and fertilizers. The highest grain yield of 4.87 t ha-1 was observed in the treatment T3 [PM + STB-CF (HYG)] and the lowest value of 3.61 t ha-1 was found in T0 (control). The straw yield ranged from 4.10 to 5.51 t ha-1 in different treatments. The NPKS uptake by BRRI dhan49 was markedly influenced by manures and fertilizers. Based on overall results, the treatment T3 [PM + STB-CF (HYG)] was found to be the best combination of manures and fertilizers for obtaining the maximum yield and quality of rice.

Inorganic fertilizer application and the quantity required by the crop for optimum production led agronomists to introduced varying measures in crop production. A study to investigate the effects of single and split NPK 15-15-15 fertilizer application on muskmelon (Cucumis melo L.) production was conducted at the Teaching and Research Farm of Ekiti State University. A 4 × 2 factorial experiment laid out in a Randomized Complete Block Design in three replicates with four varying rates (0, 167, 333 and 500 kg ha-1) of NPK 15-15-15 fertilizer applications and two-mode of applications (single and split) serves as the treatments. Data collected include the number of leaves and branches, vine length, number of fruits, fruit length and width, fruit weight, fruit flesh thickness (fruit pulp width), number of seeds fruit-1 and seed weight. Collected data were subjected to analysis of variance (ANOVA), and treatment means separated with Duncan Multiple Range Test at 5% level                            of probability. The split application at 333 kg ha-1 NPK fertilizer produced a significantly higher number of leaves (90), leaf area (109.58 cm2) and vine length (110.77 cm) at 10 WAS than other applied fertilizer rates. The split application of 500 kg ha-1 NPK fertilizer produced a higher fruit yield                    (12.64 t ha-1) than 12.09 t ha-1 from the single application which was not significantly different                  from the 333 kg ha-1 NPK fertilizer. The results indicated that the split application of NPK                 fertilizer is a better fertilizer application approach than a single application for muskmelon production.
