The experiment was conducted at Horticulture Farm of Agriculture and Forestry University, Rampur, Nepal during the November 2016 to March 2018 for two consecutive years to assess the characteristics on postharvest quality of late season cauliflower varieties. The experiment was laid in a Randomized Complete Block Design (RCBD) with the eleven late season cauliflower varieties viz., Freedom, Titan, Ravella, Amazing, Artica, Bishop, Casper, Indam 9803, NS 106, Snow Mystique, and Snowball 16, each replicated with four times. Significantly higher TSS value of 5.7º Brix was produced by Snowball 16 than other varieties. Considerably higher vitamin C of 49 mg/100 g was found in Amazing than other varieties. Significantly lower physiological loss in weight of 5.3%, 9.6% and 15.6% was found in Artica at three, six and nine days after harvesting, respectively. Higher score for the taste of curd was 8.8 in Snowball 16 followed by Amazing while lower score for taste of the curd was 4.8 in Indam 9803 variety. The attractive color and more compact curd score of 8.4 was found in both Titan and Artica than other varieties. Therefore, it can be concluded that Snowball 16 and Amazing varieties were the best open pollinated varieties for taste of the curd and composition of chemical constitutes. Bishop, Snow Mystique, NS 106, Artica and Titan varieties were other probable hybrid varieties based on their overall postharvest characteristics.

In Nepal, there is lacking of proper nitrogen management regarding postharvest quality of cauliflower in the Terai region of Nepal. In order to address these problems, a field experiment was conducted in a split-plot design to determine the appropriate dose of nitrogen and combined effect of urea and poultry manure for better postharvest quality of cauliflower in Rampur, Chitwan. The study was carried out in nine treatment combinations from two different factors, with four replications in a late season variety, Bishop from November 2017 to March 2018. The plots consisted of three treatments of 260, 200, and 140 kg N/ha, while the sub-plots were 100 % N from urea; 50% N from urea and 50% N from poultry manure; and 100% N from poultry manure. Significantly higher vitamin C content of 52.4 mg/100 g was found in 140 kg N/ha than other treatments. Similarly, higher TSS content of 6.3°Brix was found in 260 kg N/ha. More compact and acceptable curds were produced in 260 kg N/ha. Similarly, higher vitamin C content of 52.0 mg/100 g and higher TSS content of 6.0°Brix was produced by 50% N from urea plus 50% N from poultry manure. Significantly more tastier and compact curds were produced by 100% N from poultry manure along with 50% N from urea and 50% N from poultry manure. Higher physiological weight (30.3%) was found in 260 kg N/ha while lower physiological weight loss (24.4%) was found in 50% N from urea and 50% N from poultry manure. From this study, it was concluded that 200 kg nitrogen combination with poultry manure instead of inorganic fertilizer can improve the postharvest quality of cauliflower in Terai region of Nepal.

Abstract: The objective of this work was to evaluate the effects of the mutant alleles alcobaça (nor A ), ripening inhibitor (rin), and old gold crimson (og c ), in heterozygosity or homozygosity, on the expression of color and on the postharvest quality of fruit of experimental tomato hybrids. Fourteen hybrids with contrasting genotypic constitutions in the nor A , rin, and og c loci were evaluated in a randomized complete block design with four replicates. The following fruit postharvest quality traits were evaluated: firmness in the breaker stage, color, and soluble solids content. The rin +/rin and nor +/nor A genotypes increased firmness of tomato fruit at harvest (breaker stage). The rin + /rin genotypes displayed the worse internal fruit color. There was a positive effect of og c+ /og c in improving the internal color of rin + /rin and nor + /nor A fruit, making the color similar to that of the normal genotypes. The combination of the og c /og c rin + /rin nor + /nor A genes is effective to improve tomato fruit firmness, besides maintaining or improving internal color.

The trial was carried out at Três Pontas, Minas Gerais State, Brazil, from April to July 2003, to evaluate the influence of nitrogen and molybdenum rates on productive characteristics and postharvest quality of crisphead lettuce (Lactuca sativa L.). A randomized complete block design with three replications was used. Treatments were a factorial combination of four nitrogen rates (0.0; 60.0; 120.0 and 180.0 kg ha-1) applied in additional the dose commonly used by growers (60 kg ha-1 of N) and five foliar molybdenum rates (0.0; 35.1; 70.2; 105.3 and 140.4 g ha-1). The total and commercial fresh weight and head circumference showed significant effects for doses of nitrogen and of molybdenum, as well as for their interaction. No significant effects of the treatments for stem length were observed. There was a linear effect of N and Mo doses for postharvest conservation at 28 days, and the rate of 150.0 kg ha-1 of N showed the best conservation at 35 days after the harvest. The percentage of dry matter showed quadratic effects, and the doses of 95.9 kg ha-1 of N and 75.3 kg ha-1 of Mo showed the highest return.

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.

The efficiency and responsiveness agronomic to the main macronutrients is becoming increasingly important due to the risk of supply, since it is a finite resource. In addition, excess fertilizer decreases the quality of water and air. Thus, the objective of this work was to assess the corn hybrids in terms of their efficiency and responsiveness to nitrogen (N), phosphorus (P) and potassium (K), and identify the ones most suitable for fresh consumption, according to the product type and technological level to be adopted by the farmer. The randomized complete block design in a 10 × 3 (hybrids and doses) factorial scheme was adopted for the experiment, with three replications, for two season crops (2013/14 and 2014/15). Ten hybrids (2B512PW, 2B587PW, 2B707PW, 30F35HR, 30F53YH, AG1051, BRS1055, BM3061, P3646H e P3862YH) were used in isolation under low availability (without application) and partial, of N, P and K, in an isolated manner, also evaluated under the recommended dose, aiming at fresh consumption. The most efficient and responsive hybrid must first be identified in isolation, based on the availability it is subjected to and later, by its sale, focused on fresh consumption. The hybrids indicated for low availability (low technological level) were BRS1055 and 30F53YH, with respect to responsiveness or agronomic efficiency, the hybrid P3862YH was the one that presented the best performance and indicated for technological levels of medium to high, considering the classification obtained for the nitrogen, phosphorus, and potassium for production vegetable corn.

Reducing productivity, outbreak of insects and diseases, and decreasingin physical and cup quality are major problems for Arabica coffee cultivation inmedium altitude. The aim of this study was to investigate the effect of altitude onphysical quality in eight genotypes of Arabica coffee. This research was conductedat two locations i.e. Andungsari Research Station-Bondowoso (1250 m asl. ashigh altitude) and Kalibendo Estate-Banyuwangi (700 m asl. as medium altitude).Randomized complete block design was used with three replications. Collecteddata consisted of outturn, weight of 100 beans, shape bean normality, apparentswelling, bulk density before and after roasting. Combined analysis on the physicalquality traits of green bean showed genotype x altitude interactions on weight of100 beans, percentage of normal beans and percentage of empty bean. Altitudesignificantly influenced coffee outturn. Decreasing in altitude from 1.250 m asl.to 700 m asl. caused declining in the outturn as much 32.9%. BP 700A, K 29, K34, K 79, and K 99 were genotypes that stable to produce normal bean and emptybeans at high and medium altidute, while K 8, K 130, and SIG were genotypeswith high normal beans at high altitude but not stable. Genotype x altitude interactiondid not occur for physical quality of other variables of outturn, bulk densitybefore and after roasting, apparent swelling, percentage of round beans,percentage of elephant beans, and percentage of triage beans. Altitude showedsignificant effect on all of physical quality of bean variables.
