The objective of this study was to evaluate the productivity and quality of melon fruits as a function of the dose and time of application of biostimulant in the conditions of the semi-arid region of Paraíba. The experiment was carried out at the Federal University of Campina Grande, campus of Pombal - PB, Brazil, in a randomized block design in a 4 x 5 split plot scheme, with doses of biostimulant (0; 0.5; 1.0; 1, 5 and 2.0 L ha-1) and in the subset of the biostimulant application times (15; 20; 25 and 30 days before harvest - DAC), in four replications. Characteristics related to fruit production and quality were evaluated. There was no interaction between the factors of dose and application time of the biostimulant in any of the evaluated characteristics. Thus, the highest estimated values of number of fruits per plant, fruit mass and total melon production were obtained with the application of doses ranging from 0.9 to 1.5 L ha-1 and at the time of application it varied from 22,5 to 23.6 DAC. The content of soluble solids increased 5.5% when the biostimulant dose of 2.0 L ha-1 was used and 4.4% when the product was applied 15 days before harvest.

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.

Tomato is one of the most consumed vegetables in the world. This work aimed to evaluate post-harvest quality of Italian Saladete tomatoes grown in a protected environment, with different ways of calcium application, in the Middle São Francisco Valley. Consisting of five Italian tomato hybrids (Anjico, Gabrielle, Liberty, Ty 2006 and Shanty), and three different ways of calcium application (T0 without application of calcium; T1 application of calcium in the opening flower, and T2 weekly application of calcium in the fruit).  Poductivity, average fruit mass, incidence of apical rot, fruit firmness, soluble solids (SS), titratable acidity (AT), and pH, were analized. The experimental design used was a completely randomized block design in a factorial scheme (five cultivars x three ways of calcium application), with three repetition and using two central plants as useful plot for analysis, except for fruit firmness that was carried out in a completely randomized design, using tree fruits per analysis. According to the results obtained, hybrids of Italian saladete tomatoes behaved in a satisfactory manner, therefore it is recommended to cultivate hybrids of Italian saladete tomatoes in the Middle São Francisco Valley, mainly hybrid Anjico. Calcium application way did not interfere with post-harvest attributes.

ABSTRACT Squashes and pumpkins are known and grown worldwide, including the Tetsukabuto type, a hybrid of Japanese origin. On this work, we evaluated yield and quality of parthenocarpic fruits of hybrid Tetsukabuto developed with the use of 2,4-D doses, in the climatic conditions of the Brazilian semiarid, in the city of Pombal, state of Paraíba, Brazil. The experiment was carried out from February to May 2013, in complete blocks at random and five replications. Treatments corresponded to five 2,4-D doses (0, 90, 180, 270, and 360 mg/L) applied to female flowers, and a control treatment, where fruits developed out of insect pollinated flowers. We evaluated number of flowers per plant, duration of flowering, number of fruits per plant (used to estimate number of fruits per hectare), fruit set index, fruit mass and transversal and longitudinal diameters, pulp thickness and content of soluble solids, total fruit production and yield. Number of fruits per plant and fruit mass increased 269.5 and 15.4%, respectively, with 212.1 mg/L and 360.0 mg/L of 2,4-D, when compared to the control treatment. Increasing the 2,4-D dose from 0.0 to 241.4 mg/L resulted in 38.2% rise in plant production. Correlations were significant only for number of flowers x number of fruits per plant (NF) and NF x yield, with coefficients of 87.5 and 82.7%, respectively. These results indicate that fruit induction using 2,4-D resulted in higher fruit set, independent of the 2,4-D dose applied.

Nitrogen Rates

The aim of this paper is to evaluate the yield and quality of 'Pérola' pineapple under increasing rates of nitrogen and potassium applied through fertigation. The experiment was conducted in a randomized block design, with four replications, in a factorial scheme (4x4), which represents four nitrogen rates (128, 256, 384 and 512 kg ha-1 of N) and four potassium rates (192, 384, 576 and 768 kg ha-1of K2O) via fertigation. The evaluations consisted of physical and chemical fruit characteristics and yield. Increasing nitrogen rates provided linear growth on fruit production features and the rate of 516 kg ha-1 resulted in fruits with the largest diameters. The highest total yield on 'Pérola' pineapple crop was reached on plants under the supply of 498 kg ha-1 of K2O. Rates between 523 and 583 kg ha-1 of K2O, provided the largest fruit matter and the highest fruit pulp yield. The increasing amount of nitrogen applied by fertigation resulted in linear growth on fruit pulp pH, though it did not influence the soluble solids content. The lower acid content and higher SS/acid ratio on fruits were reached with the N rates of 333 and 375 kg ha-1 respectively.

Sugar apple fruit are widely appreciated because of their flavor and functional qualities. However, the final value of the fruit varies according to its physical, physicochemical, and organoleptic qualities. The production and attributes that make up the quality of fruit can be influenced by climatic seasonality in both seasons (dry and wet). Therefore, this work aimed to evaluate whether the production and quality of fruit production of different size classes of A. squamosa L. in two seasons are affected by climatic seasonality. The experiment consisted of a randomized block design, with 4 blocks and 10 plants per block. The variables evaluated were number of fruit per hectare, production, and yield. The postharvest evaluation of the fruit consisted of a completely randomized experimental design, in a 3 × 2 factorial scheme, which referred to the three sizes and two seasons, and evaluated fruit length and diameter; firmness; fruit, bark, and seed weight; number of seeds; soluble solids; hydrogen ionic potential (pH); titratable acidity (TA); and ratio. The 2014 season had larger fruit in relation to those of the 2015 season; conversely, it showed a lower number of fruit per plant, production, and yield, besides inferior organoleptic quality. Fruit of size class 2 stood out in the 2014 season because of their physical characteristics. However, they had inferior organoleptic quality when compared with fruit of the same size collected during the 2015 season. Fruit of size class 3 (≥8.1 cm) had greater firmness, providing longer durability and shelf life.

Brassica Oleracea L

A field experiment was undertaken at B.B.A. University, Lucknow (UP) during rabi season to study the effect of varieties and spacings on yield and quality characters of sprouting broccoli (Brassica oleracea L. var. italica Plenck). Four varieties viz. V1- Pusa Broccoli KTS-1, V2-Palam Kanchan , V3-Palam Vichitra , V4-Palam Samridhi and four spacings viz.- S1- 60x45 cm, S2 - 60×30 cm, S3 - 45×45 cm, S4 - 45×30 cm were evaluated in factorial randomized block design with three replications. Among the varieties, Pusa Broccoli KTS-1had takenearliest days for curd initiation (47.9) and day taken to curd harvest after curd initiation (22.5). Variety Pusa Broccoli KTS-1 significantly produced the highest curd diameter (118.9 mm),weight of curd with gourd leaf(0.9kg), weight of curd without gourd leaf (0.4 kg), yield (24.5 tha-1),ascorbic acid (79.1 mg/100g) and total soluble solids (8.5oBrix). On the other hand, minimum values of these parameters were recorded in Pusa Samridhi. Spacing of 60x45 cm took minimum days (48.9) for curd initiation, (22.5) and days taken to curd harvest after curd initiation. Maximum curd diameter (116.8 mm), weight of curd with gourd leaf (0.9 kg), weight of curd without gourd leaf (0.4 kg) were recorded in 60x45 cm spacing. Quality parameters were also markedly affected with variety Pusa Broccoli KTS-1 and spacing 60x45 cm and relatively higher value of vitamin C (79.9 mg/100g) and total soluble solids (8.80Brix) were recorded under V1S1 treatment.

Pollen Quantity

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.

Among the problems faced by the melon crop in the state of Rio Grande do Norte, northeastern Brazil, the effect of water and soil salinity is considered one of the key factors to limit fruit production and quality. The aim of this work was to study the effects of using irrigation waters with different salinity levels on yield and quality of fruits of the yellow melon hybrid Mandacaru. A randomized complete block design was used with five treatments (irrigation water salt concentrations: 0.54, 1.48, 2.02, 3.03, 3.9 dS m-1) and four replications. The effects of these concentrations were evaluated through, number of marketable fruits per plant, marketable and total fruit yield, average marketable fruit mass, soluble solids content and pulp firmness. Increment in water salinity level negatively influenced crop yield. The 3.9 dS m-1 salinity level caused yield losses of 20.31%, due to the reduction of fruit number per plant. The highest soluble solid content and the highest pulp firmness values were estimated to occur at salinity levels 2.09 and 3.5 dS m-1, respectively.

The present investigation was carried out to study the effect of off season soil management practices on yield and quality of turmeric (Curcuma longa L.) cultivars. The experiment was laid out in a Factorial Randomized Block Design with ten treatments in three replications consisted of five off-season land management treatments viz., fallow (S1), summer ploughing 2 times (S2), summer ploughing 1 time (S3), solarization with transparent polyethylene film of 0.05 mm thick for 40 days (S4) and black polyethylene film for 40 days (S5). It was tested with two popular cultivars viz., Curcuma longa -1 CL-1 (V1) and Curcuma longa-2 CL-2 (V2), collected from Erode and Chidambaram. Various yield components were recorded at the time of harvest and were analysed. The yield attributing characters viz., number, length, girth and weight of mother, primary and secondary rhizomes were recorded. The treatment where solarization with transparent polyethylene film of 0.05 mm thick was tested recorded the highest yield and yield attributing characters when compared to other treatments. The same treatment also exhibited the highest fresh rhizome yield per plant, curing percentage and cured rhizome yield. The quality parameters like curcumin, oleoresin and essential oil content were also showed superior performance in the treatment where solarization with transparent polyethylene film of 0.05 mm thick was applied.
