Tomato (Lycopersicon esculentum) is highly perishable and has potential for processing industries in bumper producing seasons in Nepal. The study on judicious use of nitrogen and potassium levels was aimed to explore the quality attributes along with the shelf life of tomato fruits. Three levels of nitrogen comprising 0 kg/ha (N0), 100 kg/ha (N100), 200 kg/ha (N200) and four levels of potassium 0 K2O kg/ha (K0), 80 K2O kg/ha (K80), 160 K2O kg/ha (K160), 240 K2O kg /ha (K240) were used as treatments in randomized complete block design with three replications at Chitwan (Inner Terai) Nepal. Tomatoes at breaker stage were harvested from the field and 10 fruits from each treatment per replication were kept for physiological weight loss, color rating and shelf life in ambient condition (17.5±3 0C and 80.5±6.5 % RH). Fruit quality with respect to physicochemical properties like firmness, TSS, TA, pH and Vitamin C was assessed at the end of shelf life. Higher potassium levels hasten color development and increased TSS, firmness and vitamin C content. Physiological weight loss was greatly reduced and extended shelf life was achieved with 100 kg N/ha and 240 kg K2O/ha.

Dietary intake of a variety of vegetables is very important for disease prevention and may help in the treatment of certain maladies. Experiments were conducted to evaluate yield and the content of antioxidants and phenolics of vegetable Amaranth (Amaranthus hybridus), Celosia (Celosia argentea), Gboma (Solanum macrocarpon), and Long Bean (Vigna unguiculata) in response to poultry litter (PL) and a hydrolyzed fish fertilizer [Megabloom (MB)]. The experiments were conducted as a randomized complete block design with a four × three factorial treatment and four replications. The treatments were applied based on soil test recommendations in a single band 15 to 20 cm away from the plants 1 week after transplanting. Plants were harvested sequentially during the season as foliage and fruits became physiologically mature and once over at the end of the season. Species were analyzed for vitamin C content, total phenolics, and β-carotene content as well as antioxidant capacity. Organic amendments did not significantly influence biomass production, whereas species impacted fresh and dry biomass. Amaranth, Celosia, and Long Bean produced greater fresh and dry biomass than did Gboma. Vitamin C content was highest among Amaranth and Celosia plants receiving nitrogen–phosphorus–potassium (NPK) compared with the other two treatments, whereas that of Gboma was higher among plants receiving MB.

Pruning Methods

This study was carried out to determine the effect of vine and fruit pruning on watermelon (Citrullus lanatus) yield. Five pruning methods: P1=no pruning at all, P2=pruning to four vines with two fruits per vine, P3=pruning to four vines with one fruit per vine, P4=pruning to three vines with two fruits per vine and P5=pruning to three vines with one fruit per vine were evaluated on two watermelon cultivars: ‘Sugar baby’ and ‘Julie F1’ under a factorial randomized complete block design with three replications. Investigations were carried out in the seasons 2017A (short rains) and 2017B (long rains) at Karama and Rubona experimental sites belonging to Rwanda Agriculture and Animal Resources Development Board. The obtained results indicated a significant difference among the different cultivars and pruning methods tested during both seasons and at two sites. Generally, all studied parameters recorded higher values during season 2017B than in season 2017A at Rubona site. A similar trend was recorded at Karama site except that the fruit yield per plant and per hectare for plants which were pruned to three vines with one fruit reduced during season 2017B as compared to season 2017A. The highest number of fruits per plant, fruit weight, fruit yield per plant and per hectare was recorded in ‘Julie F1’ compared to ‘Sugar baby’ at both sites and during both seasons. Higher fruit weight was obtained when both cultivars were pruned to three or four vines with one fruit per vine. Higher number of fruits per plant and higher fruit yield per plant was observed under pruning to four vines with two fruits per vine at Rubona site; while at Karama site, higher fruit yield per plant was recorded under pruning to three vines with one fruit or two fruits per vines and pruning to four vines with two fruits per vine. A similar trend was observed in fruit yield per hectare. Based on results of the current study, cultivation of the hybrid ‘Julie F1’ and pruning to three vines with one fruit per vine is recommended for optimum watermelon yield with big-sized fruits.

A field experiment was carried out at Rampur, Chitwan, Nepal during September, 2007 to February, 2008 to assess the response of cauliflower (Brassica oleracea L. var. botrytis cv. Kathmandu Local) to biofertilizer containing free living nitrogen fixing bacteria Azospirillum and Azotobacter and different levels of nitrogen. The experiment was laid out in factorial Randomized Complete Block Design consisting of 10 treatments (nitrogen 0, 30, 60, 90 and 120 kg ha–1 alone and in combinations of 2 kg of the nitrogen fixing biofertilizer) arranged in 5 × 2 complete factorial with 3 replications. Application of nitrogen along with the biofertilizer significantly increased morphological, yield and quality characters as compared to application of nitrogen without biofertilizer. The maximum stem height, stem diameter, highest curd height, curd diameter, fresh curd weight and curd yield were recorded at 120 kg nitrogen and 2 kg biofertilizer ha–1. Cauliflower curd yield obtained at 120 kg nitrogen ha–1 did not significantly differ with the curd yield recorded at 60 kg nitrogen and 2 kg biofertilizer ha–1. The earliest days to curd initiation and maturity were recorded at 30 kg nitrogen and 2 kg biofertilizer ha–1. The highest vitamin C content of curds and the most attractive curd color were recorded at 60 kg nitrogen and 2 kg biofertilizer ha–1, while the appearance and over all acceptability were recorded at 120 kg nitrogen and 2 kg biofertilizer ha–1. The finding demonstrated a saving of 60 kg nitrogen ha–1 without significantly affecting yield.

Abstract Gandaria leather is a kind of fruit leather processed by gandaria fruit in the form of thin sheets with a thickness of 2-3 mm and has a specific consistency and taste according to gandaria fruit. The purpose of this study was to determine the effect of added sugar on the physicochemical characteristics of gandaria leather. This study used a single-factor completely randomized design, with 0%, 5%, 10%, and 15% sugar concentrations. The results showed that the sugar concentration had a very significant effect on the parameters of water content, total sugar, total acid, vitamin C, and water activity (aw), and had a significant effect on the tensile strength of gandaria leather. The physicochemical characteristics of gandaria leather from various sugar concentration treatments are as follows: water content (14.05% -20.13%), total sugar (80.56% - 84.90%), total acid (3.10 - 12.37 mg/100g), vitamin C (59.44 - 78.48 mg/100g), water activity (0.48 - 0.62), and tensile strength (0.20-0.37 N). The resulting gandaria leather qualifies as good fruit leather, and the treatment with a 10% sugar concentration is recommended for gandaria leather which has the potential to be developed and commercialized.

       Guava (Psidium guajava L.) is a plant whose fruit is very popular in Indonesia because it contains high vitamin C and its leaves can be used as herbal medicine. Orchard expansion of selected cultivars and fruit production of guava can be achieved vegetatively through  propagation by using mini-cuttings with the use of Indole Butyric Acids (IBA). A study was conducted to compare rooting success of mini-cuttings of herbaceous stem of four guava cultivars with IBA treatment. Four guava cultivars tested were Bengkulu Round, Getas, Crystal, and Bangkok.  Mini-cuttings were immersed in IBA solution at 0 ppm or 1000 ppm. Cultivar and IBA treatments were arranged factorially in a randomized complete  block design with  3 replications, each consisting of 25 cuttings. Variables observed included percentage of original-leaf shedding, percentage of emerging shoots, percentage of sprouting cuttings, new leaf number, root number, root length, and percent of rooted cuttings. The results demonstrated that cultivars affected rooting percentage, sprouted percentage, percentage of original-leaf fall, and number of root.  Getas had highest rooting and sprouting percentages, and showed lowest number of  original-leaf shedding; whereas, Bangkok demostrated greatest number of root.  IBA treatment increased the number of root and the number of original-leaf shedding, but reducing rooting percentage of mini-cutting. There was no interaction between cultivar and IBA teratment.
