This experiment was conducted in tomato field at Agriculture and Forestry University (AFU, Chitwan, Nepal) between October 2016 and May 2017 to evaluate effect of net house on invasive insect species of tomato moth, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). The trial was setup with two treatments inside net house and under open conditions and was designed with four replications. The adults of T. absoluta were observed significantly lower numbers inside the net house (1.41 adult/trap) compared to the open condition (24.84 adult/trap). The T. absoluta population increased with rainfall. The marketable yield was significantly higher inside the net house (100.91 ton/hec) due to reduction of damage to tomato fruit (4 ton/hec) by T. absoluta. The initial level of investment was found to be higher inside the net house when compared to open cultivation. In terms of economic analysis in long term aspect only, the net house is a suitable means of pest management against T. absoluta.

Processing of melon plays a significant role in the livelihood of rural women as it serves as their major occupation. Despite its significant role, the women processors were faced with some challenges. This study, therefore, identified the challenges faced by women in melon processing in Enugu-Ezike Agricultural Zone of Enugu State, Nigeria. Primary data were collected from 80 respondents using a structured questionnaire coupled with an interview schedule and analysed using descriptive statistics. The results showed that the majority of the women processors were advanced in age, well experienced, do not belong to a cooperative society, and relied strictly on processing melon as their source of livelihood. They had an average income of N286,400 (USD 751.71) per annum. Low capital, poor credit facilities, high transportation cost, price fluctuation, rapid deterioration, low supply of melon, poor storage facilities, high cost of processing machine, and breakage of seed were the identified constraints facing them. The study recommended that the women processors should form a cooperative society which will help in financing and easy marketing of their products. Also, the government should provide financial assistance, good storage facilities, and subsidized melon processing machine to increase efficiency.

Küresel ısınmadan kaynaklanan iklim değişimi ve hızlı nüfus artışına bağlı olarak tüketimin yükselmesi doğal kaynaklardan suyun azalmasına neden olarak varlığını tehdit etmektedir. Dünyada kullanılabilir suyun büyük bir bölümü tarımda değerlendirildiğinden bitkilerin su ihtiyacının en doğru ve ekonomik şeklide karşılanması gerekmektedir. Bu bağlamda da suyun verimli ve ekonomik kullanılmasını sağlayan yöntemlerden biri olarak su tutucu polimer (SAP) uygulaması karşımıza çıkmaktadır. Araştırmada, su tutucu polimer SAP A200’ün farklı dozları [% 0 (kontrol), % 0,2, % 0,4 ve % 0,6 v/v] geleneksel (toprak) ve topraksız tarım yetiştirme ortamlarına [torf, perlit ve torf:perlit (1:1) v/v] uygulanmıştır. SAP A200 dozlarının Anadolu Sığla Ağacı (Liquidambar orientalis Mill.) ve Biberiye (Rosmarinus officinalis L.) türlerinin bitki gelişimine etkisinin belirlemesi amaçlanmıştır. Araştırma tesadüf parselleri deneme desenine göre 3 tekerrürlü olarak kurulmuştur. Bitki gelişim özelliklerini belirlemek amacıyla bitki boyu, gövde çapı, kök uzunluğu, kök kalınlığı, kök ile sürgün yaş ve kuru ağırlıkları belirlenmiştir. Araştırmadaki iki tür için, tüm SAP dozlarının bitki gelişim parametrelerini olumlu yönde etkilediği ve en yüksek değerlerin % 0,6 SAP A200 uygulamasında tespit edildiği gözlemlenmiştir. Toprak dışındaki tüm yetiştirme ortamlarında bitki gelişim değerlerinin daha yüksek olduğu ve en iyi sonuçların torf:perlit ortamında gerçekleştiği saptanmıştır.
Mostrar más [+] Menos [-]UV-B Radiations and Secondary Metabolites Texto completo
2020

Ultraviolet-B (UV-B: 280 to 320 nm) radiations have appeared to be detrimental to plants, due to their damaging effects on proteins, lipids, membranes and DNA. UV-B radiations are a significant regulator of plants’ secondary metabolites. High intensity of ultraviolet radiations may interfere with growth and productivity of crops. But low levels of UV-B radiations give rise to changes in the plants’ secondary metabolites such as phenolic compounds, carotenoids and glucoseinolates. Therefore, low intensity of UV-B radiations may be used to generate plants, enriched with secondary metabolites, having improved reproductive ability, early ripening and tolerance against fungi, bacteria and herbivores.
Mostrar más [+] Menos [-]Weed-Competitive Ability of Forage Maize Cultivars against Barnyardgrass Texto completo
2020
Khawar Jabran
Weed-competitive cultivars are desired in the wake of growing popularity of organic farming, environmental pollution and evolution of herbicide resistance in weeds. This research work evaluated the weed competitive ability of three forage maize cultivars (ADA-523, AGA and SASA-5) against the noxious weed barnyardgrass (Echinochloa crus-galli (L.) P.Beauv.). The study was conducted in spring 2018 and repeated in summer 2018. Results of this study showed that maize-barnyardgrass competition significantly decreased the growth of forage maize plants. For instance, barnyardgrass decreased the maize plant height by 11.9-16.9%, leaf length by 13.3-20.2%, leaf width by 20.2-27.4%, and number of leaves by 14.3-25.0%. Fresh and dry weights of maize plants were also significantly decreased as a result of weed-crop competition. Barnyardgrass decreased the shoot fresh weight (30.7-60.6%), shoot dry weight (33.3-52.2%), leaf fresh weight (33.4-56.5%) and leaf dry weight (31.9-50.0%) of the maize plants. An interactive effect of weed × maize cultivars was found non-significant. Forage maize cultivars also varied occasionally for their traits. Nevertheless, ADA-523 had a higher plant height, leaf length, leaf width, leaf fresh weight and leaf dry weight than the cultivars AGA and SASA-5. On the other hand, the cultivar SASA-5 had a higher shoot fresh weight, shoot dry weight and root fresh weight than the other cultivars in the study. This research work concluded that the forage maize cultivars in the study did not vary for the weed-competitive ability. Further, barnyardgrass-maize competition could decrease the growth and development of the maize cultivars.

This study was carried out to determine the influence of different levels of alfalfa meal and the addition of enzyme on performance, carcass and intestinal parameters in growing quails. Japanese quails (n=240), 1 days of age, were divided into 6 dietary treatment groups and the experiment lasted for 5 weeks. In each experiment group there were 4 replicates, and in each replicates there were 10 chicks. Six diets, arranged a factorial design with three alfalfa meal levels (0, 2.5 and 5.0 %) and two levels of added enzyme (0.0 and 1.0 g/kg) were used. The treatments did not effect on the body weight, feed intake and feed conversion ratio. However, relative liver, leg+back, intestine weights and crypt depth were significantly increased, and relative heart and breast weights and villus width decreased by dietary alfalfa meal levels. The addition of enzyme to diets containing alfalfa meal did not affect the performance and carcass parameters, but reduced the intestinal histomorphology parameters in quails. According to the results obtained from the experiment, it can be said that the use of alfalfa meal in growing quail diets did not affect the performance, but the use of alfalfa meal at the level of 2.5% in the diet promotes intestinal development.

Due to a better understanding of its positive effects on nutrition and health, consumer demands for sesame seeds and products have increased steadily in recent years. The aim of the study is to determine the total phenolic content belonging to 17 different sesame genotypes (with different seed color) and the antioxidant content by DPPH and ABTS methods. The total amount of phenolic substance varied between 1.99-6.81 mg GA/g, and the highest amount of phenolic content was obtained from the Libya genotype, while the lowest value was obtained from the Gaziantep-Oğuzeli genotype. While antioxidant activity values obtained according to DPPH method varied between 8.23 and 17.50 mg Trolox/g, antioxidant activity values obtained according to ABTS method ranged between 3.62 and 4.18 (mmol Trolox)/g. According to the correlation analysis, it was determined that there was a statistically significant and positive relationship between antioxidant capacities according to total phenolic content, DPPH and ABTS methods. However, no relation was found between the seed color and these properties.

Berken Çimen | Turgut Yeşiloğlu | Yıldız Aka Kaçar
The existence of a large amount of seeds in citrus fruits results as a major impediment to customer acceptability, even if the fruits have high organoleptic properties. Irradiation, which mainly reduces seed number of varieties, is a faster way than hybridization. The use of irradiation in citrus breeding programs is now quite widespread with most programs in the major citrus producing countries actively developing new selections. The present study reports the primarily results of gamma irradiation on seed number and fruit quality of Ortanique tangor mutant population. The shoots of scion were irradiated with gamma rays from 60Co at the dose of 50 Gy (gray) in April of 2014. All the treated buds were then immediately budded onto rootstocks and the survival rate was recorded as 60.34%. In order to stabilize the mutation, mV3 plants were developed by re-budding and plants at mV3 generation were transplanted in the orchard in 2017. Within the following year, 68 mV3 plants out of 852 grown in the field bore sufficient amount of fruit and were screened in terms of 19 fruit quality characters such as seed number per fruit, fruit diameter and ripening index. Fruit diameters of mV3 population varied from 56.72 mm to 84.79 mm, and fruit weight ranged between 90.00 g and 287.60 g. The number of seeds per fruit ranged between 0.6 and 13.1 whereas seed number of non-irradiated Ortanique tangor was recorded as 10.7 in the same fruit crop year. In general, fruit characteristics such as fruit weight, fruit height and fruit diameter which describe fruit size of a big part of the population, were similar to Ortanique tangor. According to primarily results, 18 plants have been described as low seeded (≤4). In addition, a cluster analysis was performed by using Euclidean similarity coefficient and similarity index ranged between 29.29% and 93.10% regarding variables related to fruit. The stability of mutations detected is being evaluated and new commercial field trials will be established with the selected materials.
