<p>Ketersediaan varietas baru melon yang sesuai dengan permintaan konsumen akan membuat komoditas ini lebih berharga sehingga dapat meningkatkan pendapatan petani. Secara umum, karakteristik melon yang diinginkan adalah manis, renyah, beraroma kuat, kulitnya berjala, dan tahan simpan. Sampai saat ini ada dua kandidat melon hibrida yang sedang dievaluasi. Pada tahun 2012 dilakukan uji penanaman dua calon varietas melon tersebut. Tujuan penelitian adalah untuk melakukan evaluasi dua calon varietas unggul baru (genotipe MB1 dan MB2) di tiga lokasi tanam dan juga untuk memperoleh calon varietas melon baru. Penelitian dilakukan di Kebun Percobaan Sumani (Solok, Sumatera Barat), Subang (Jawa Barat), dan Banyuwangi (Jawa Timur). Penelitian menggunakan rancangan acak kelompok dengan empat perlakuan, yaitu dua calon hibrida: 86H (MB1) dan 78M (MB2) dan dua varietas pembanding (Tropika dan Glamour), dengan enam ulangan. Setiap unit perlakuan terdiri dari 30 tanaman. Hasil penelitian menunjukkan bahwa terdapat interaksi nyata antara genotipe x lingkungan terhadap karakter berat buah dan total padatan terlarut. Hasil penelitian menunjukkan bahwa pada karakter berat buah dan total padatan terlarut, genotipe 86H/MB1 memiliki koefisien regresi (βi) &gt; 1, artinya genotipe memiliki stabilitas di bawah rerata (mempunyai daya adaptabilitas spesifik pada suatu lingkungan yang menguntungkan), sebaliknya untuk genotipe 78M/MB2 memiliki koefisien regresi (βi) &lt; 1, yang berarti genotipe 78M/MB2 mempunyai stabilitas di atas rerata (tidak responsif terhadap perubahan lingkungan). Berdasarkan hasil pengujian di tiga lokasi diperoleh informasi berat buah semua aksesi tertinggi pada lokasi tanam Banyuwangi, yaitu genotipe 86H/MB1 dengan berat 2,35 kg, Tropika 2,68 kg, genotipe 78M/MB2 2,05 kg, dan Glamour 2,21 kg, TSS buah pada lokasi tanam Sumani, yaitu genotipe 86 H/MB1 dengan TSS 12,47ºBrix, Tropika 11,71ºBrix, genotipe 78 M/MB2 12,88ºBrix, dan Glamour 11,89ºBrix, sedangkan persentase jaring kulit melon genotipe MB1 lokasi Sumani adalah 86% dan Banyuwangi adalah 88,67% dengan tekstur jala halus, sedikit di bawah dari pembanding Tropika 89,5% dan Glamour 89%.</p><p>The availability of new varieties of melon that suitable to the consumers demand will lead this commodity more marketable so that can increase farmers’ income. In general, expected characteristics of melon are sweet, crisp, strong-scented, rind nets, and long shelf-life. There are two candidates of melon hybrid that are being evaluated. The evaluation test of two candidates of melon varieties has been done in 2012. The purpose of this study was to evaluate the two candidates of new varieties (MB1 and MB2 genotype) in three planting locations and to obtain new candidate of melon varieties. The research was conducted in Sumani (Solok, West Sumatera), Subang (West Java), and Banyuwangi (East Java). A randomized block design was used in this experiment with four treatments [two hybrid melon candidates: 86H (MB1) and 78M (MB2)] and two other melon varieties (Tropika and Glamour) as comparator, and each treatment was replicated six times. Each experimental unit consisted of 30 plants. The result showed that there were interaction between location and genotypes on the weight and total soluble solid (TSS) characters. Fruit weight character and total soluble solid of 86H/MB1 genotype had regression coefficient (βi) &gt; 1, it mean that genotype had below average stability, while 78M/MB2 genotype had regression coefficient (βi) &lt; 1, that mean genotype above average stability. Based on test results in three locations obtained information accession with highest weight on the planting location in Banyuwangi namely genotype 86 H/MB1 2.35 kg, Tropika 2.68 kg, genotype 78M/MB2 2.05 kg and Glamour 2.21 kg. The highest TSS fruit on planting location Sumani namely genotype 86H/MB1 with TSSºBrix 12.47, Tropical 11.71ºBrix, genotype 78M/MB2 12.88ºBrix, and Glamour 11.89ºBrix. Furthermore, the net percentage of skin melon genotype MB1 on Sumani location is 86% and Banyuwangi is 88.67% with net texture smooth, slightly below of varieties Tropika 89,5% and Glamor 89%.</p>

Soilless growing systems can improve water-use efficiency, especially in closed soilless growing systems. The main purpose of this study was to evaluate the effects of different transplanting conditions, and determine how supplying H2O2 as an oxygen source to the rhizosphere of strawberry plants in a soilless growing system affects plant growth, fruit yield and fruit quality. Strawberry plants (Fragaria x ananassa Duch.) cv. ‘Fortuna’ were cultivated in 12 L pots filled with peat substrate, and maintained under conditions of natural light and temperature. Treated plants were supplied with hydrogen peroxide (H2O2) (H1) and control plants did not receive H2O2 (H0). In terms of the transplanting conditions, the plants were transplanted in October (T1), and either maintained in a culture chamber (T2), or refrigerated (T3), for one month, before being transplanted. A completely randomized block design with two treatment factors (transplanting conditions, and H2O2 treatment) and five replications was established. Then, we determined the fruit per plant, yield per plant (g plant−1), fruit weight (g fruit−1), fruit size (mm), SPAD values, crown number, crown diameter (mm), flower number, firmness (g cm−1), pH, total soluble solid (TSS), titratable acidity (TA) and TSS/TA. During the early crop cycle, there were not significant differences between treatment and the transplanting conditions that significantly affected the fruit weight and fruit size, although T3 produced the highest values. During the late crop cycle, the H2O2 treatment affected fruit per plant, yield per plant (g plant−1), and crown diameter, with H1 producing the highest values. Furthermore, the transplanting conditions affected yield per plant (g plant−1), old SPAD values, crown diameter, firmness, TSS, TA and TSS/TA.

Fertilization outside the season of Siam Orange (Citrus microcarpa L.) with Induction of Flowering and Dormancy Breaking Substances. The Siam orange (Citrus microcarpa L.) produces seasonal fruit with the on-season harvest from July to August while the off-season harvest, i.e. from February to September there is hardly any fruit, or very limited supply. The purpose of this study was to examine the response of flowering induction and dormancy-breaking substances to produce off-season fruits of Siam orange. This research began in April to December 2016. The experiment was arranged factorially with two factors using a randomized block design (RBD), with nine combination treatments and six replications. Flowering induction factors consist of three levels, namely Ik = Control, IP = Paclobutrazol at a dose of 7.5 g/l, and Im = cutting the tip of dormant twigs. Dormancy-breaking substances factor consists of three levels, namely Dk = Control, Db = BAP 200 ppm, and Dn = KNO3 300 ppm. The results of the experiment showed that the highest fruit weight per tree at off-season production was obtained by induction with paklobutrazol (28.86 kg) and the lowest was in control (12.75 kg). Flowering induction treatments was not significantly different effect on fruit quality of Siam orange, represented by weight per fruits, fruit diemater, total soluble solid and vitamine C content was not siginificant different among levels of treatment. Dormancy-breaking substances treatment also not significantly effect on fruit quality of Siam orange. Based on this research it is recommended to induce flower for off-season produce of Siam orange by pruning the tips of dormant twigs or by using paklobutrzol.

Spaghetti squash is squash of American origin that has spaghetti-like characteristic of fruit flesh, unlike any other squash varieties. This study aims to investigate the use of trellis and mulch to increase the spaghetti squash production. The experiment was conducted at the Experimental Station of Centre of Tropical Horticulture, Bogor from April to November 2016. The experiment used a completely randomized block design with four replicates. Two factors were tested, i.e. the use of trellis and mulch as the main plots, and accessions of the spaghetti squash as a sub-plot. The treatments were the use of trellis and mulch, mulch without the trellis, the trellis without mulch, and without the trellis and mulch. The spaghetti squash accessions used in this experiment were accessions from Taiwan (F1) and from America. Each experimental unit consists of five plants with a total a total of 160 plants. The results of this experiment showed that the growing squash using mulch and trellis had the greatest number of fruits per plant, more marketable fruits and had the largest fruit weight as compared with the other treatments. Taiwan accession had more fruits per plant and total marketable fruits, the largest fruit weight, the longest and widest fruits with large fruit diameter. Taiwan accession produced fruits at lower nodes of the plants, and fruits can be harvested earlier than the American accession. Correlation analysis indicated that the more fruits per plant, the more number of fruits that are marketable, the greater fruit weight and more fruits can be harvested from the higher nodes of the plants. From agronomical point of view, Taiwan spaghetti squash would be preferable to obtain the high fruit production provided the crops were mulched and grown with trellis.Keywords: Cucurbitacea, trellis, mulch, plant culture

Abstract Algae oil production for Omega-3 fatty acid supplementation yields a byproduct called Condensed Algal Residue Solubles (CARS; 25.4% DM, 19.3% CP, 8.3% Fat, 9.96% Na on DM basis), de-oiled algae cells with residual fermentation substrates. This study evaluated the use of CARS in feedlot finishing diets. Crossbreed steers, (n=480) were blocked and stratified by initial body weight (BW) into 4 blocks, and assigned randomly to treatments. Treatments were designed as a 2 x 3 factorial with 3 inclusions of CARS (0, 2.5, 5% of diet DM) and 2 different base diets representing Northern and Southern Great Plains diets. The Southern diets contained steam flaked corn and dry distillers grains while the Northern diets had dry rolled and high moisture corn with wet distillers grains. CARS replaced corn in both diets. All blocks were harvested after 148 days on feed. Performance data were analyzed as a randomized block design with CARS inclusion, base diet, and interactions as fixed effects, BW block as a random effect and pen (n=48) as the experimental unit. Orthogonal contrasts were used to test linear and quadratic effects of CARS inclusion. There were no significant interactions between CARS inclusion and diet type (P ≥ 0.49). Main effects of CARS indicated positive quadratic responses for carcass adjusted ADG, G:F, 12th rib back fat, yield grade (P &lt; 0.01; increasing to 2.5% inclusion, decreasing at 5%) and hot carcass weight was both linear and quadratic (P ≤ 0.01 and P ≥ 0.06 respectively; 969, 977, 935 as CARS increased). Linear decrease in DMI, final adjusted BW and ribeye area (P ≤ 0.01) as CARS increased. Cattle fed the Southern diets had greater ADG and G:F compared to Northern diets (P &lt; 0.01). Including 2.5% CARS in the diet improved feed efficiency in both Northern and Southern based feedlot diets.

ABSTRACT Knowledge about associations between traits is fundamental for plant breeding, since indirect selection can accelerate the development of promising genotypes. This study assessed the magnitude of associations between agronomically important traits in fisális (Physalis peruviana L). The experiment was conducted in Lages, Santa Catarina, and the treatments consisted of six fisális populations. The experiment was arranged in a randomized block design, with two replications and seven plants per plot. The correlations between traits were estimated based on the Pearson correlation coefficients and partitioned into direct and indirect effects through path analysis. Fruit weight was positively correlated with number of seeds (0.874), equatorial fruit diameter (0.738) and polar fruit diameter (0.672). By path analysis, number of seeds was identified as the trait with the highest direct contribution to fruit weight. The high phenotypic correlations between the equatorial and polar fruit diameters with fruit weight were mainly due to the indirect effect via number of seeds (0.505 and 0.459). The selection for heavier fisális fruits was strongly influenced by number of seeds, i.e., this trait should be taken into account for selection.

ABSTRACT The low fruit set is one of the main factors leading to poor yield of pear orchards in Brazil. Ethylene is associated with abscission of flowers and fruitlets. Then, the application of ethylene synthesis inhibitors, such as AVG, is a potential tool to increase fruit set of pears. The objective of this study was to evaluate the effect of AVG, sprayed at different rates and timings, on fruit set, yield and fruit quality of ‘Rocha’ pear. The study was performed in a commercial orchard located in the municipality of São Joaquim, SC, during the growing seasons of 2014/2015 and 2015/2016. Plant material consisted of ‘Rocha’ pear trees grafted on quince rootstock ‘BA29’. AVG was tested at different rates (60 mg L-1 and 80 mg L-1) and timings [full bloom, one week after full bloom (WAFB), and two WAFB), either alone or in combination. The experiment was arranged in a randomized block design, with at least five single-tree replications. The fruit set, number of fruit per tree, yield, estimated yield, fruit weight, return bloom, and fruit quality attributes were assessed. Fruit set and yield were consistently increased by single applications of AVG at 60 and 80 mg L-1 at both one and two weeks after full bloom, without negatively affecting fruit quality attributes and return bloom.

Sugarcane produces a large amount of biomass, extracts and accumulates high amounts of nutrients. In the literature the nutritional requirements for most cultivated varieties in the past are found, however there is little information on the new varieties currently planted. The objective of this study was to evaluate the nutritional requirement of four sugarcane varieties, currently very planted, in the cycles of plant-cane, first and second ratoon. The study was installed in a Yellow Oxisol. The experimental design was a randomized block design, with five replications, and four treatments: RB867515, RB92579, SP813250 and VAT90212. During maturation of the cane, in the three evaluation cycles, the productivity of natural biomass and the nutritional requirement of macronutrients of the varieties were determined. It was evidenced that the cultivars of sugarcane are of high productive potential and resemble the accumulation of biomass, observing a yield of 158, 128 and 107 t ha-1 in the cycles of plant-cane, first and second ratoon. Regarding the nutritional requirement, the varieties did not differ among them and expressed the following order of need in the plant-cane K > N > Ca > Mg > S > P, in the first and second ratoon, the sequence observed was K > N > Ca > S > Mg > P.
