The purpose of this research was the evaluation of the influence of chelate compounds of micronutrients on yield and state tubers of mid-season potato variety Kolobok during storage. The research was conducted on the fields with sod-podzolic sandy loam soil in 2016 and 2017 years. During the research one tuber processing and two foliar processing were done before planting and during vegetation respectively. The experiment had two control groups, the first group was not treated at all and the second group was treated with water. The organization of field experiment, counting and observation were done according to requirements of methods of field experiment and “Methods of investigation of potato varieties”. On average two years groups treated with drugs, which contain chelate compounds of micronutrients, had 4.4 and 4.7 main stems per bush respectively that was more than in control groups. The application of the drugs increased marketable yield by 3.5–3.7 t/ha (13.5–14.2 %). On average two years groups treated with the sulfur-containing drug had the biggest marketable yield that was 9.9 tubers per bush (1.5 tubers per bush or 17 % more than the first control group). The obtained result of the experiment means that these drugs are worth using during potato cultivation.

The study was conducted on sandy loam soil at IAAS Rampur, Chitwan during May to September, 2012 to evaluate the effect of different combinations of biogas slurry and urea on production of okra, laid out in a two-factor RCBD with three replications. Altogether ten treatments consist of two varieties namely Arka Anamika - open pollinated and Jaikisan-62-F1 hybrid and four different levels of biogas slurry and urea combination (urea75%+biogas slurry25%, urea50%+biogas slurry50%, urea25%+biogas slurry75% and biogas slurry100%) and only inorganic chemical (75:60:50 kg NPK/ha) as control. All treatments were based on fulfillment of required nitrogen for the crop. The results showed that application of urea50%+biogas slurry50% increased plant height, leaf area, number of leaves and number of nodes at final harvesting. Treatment urea50% + biogas slurry50% allow maximum number of pickings/plant (23.2) and number of fruits/plant (23.5) resulting highest yield/plant (376.3 g). Among the varieties, Jaikisan-62 is superior in terms of growth, yield and post harvest character than Arka Anamika. The net return (Rs. 474,136/ha) and mean B/C ratio was highest (2.59) in Jaikisan-62 treated with urea50%+biogas slurry50%. So, for the commercial production hybrid variety is suggested.

Abstract The aim of this work was to evaluate the effect of mulch on clay loam and sandy loam soils on the start harvest, number of fruits per plant, yield and quality of yellow passion fruits in organic crop. A complete randomized block design with five treatments and four replicates of five plants each was used. Treatments corresponded to different percentages of mulch of the area occupied by the plant (3 x 3 m), extending from the center of the planting line to the planting row in 0% without mulch (T1); 25% (T2); 50% (T3); 75% (T4) and 100% (T5). Mulch anticipated the harvest in comparison to crop in uncovered soil in both types of soil. The number of fruits per plant and yield increased in a quadratic function with maximum point of 38.6 fruits plant-1 and 5,182.0 kg ha-1 with 75.7% and 78.0% of soil cover, respectively. Mulch on clay loam soil did not provide increase in the average fruit mass and did not change the quality of fruits in relation to control fruits.

Water Table Management

In a 2-year study (1993-94), tomato (Lycopersicon esculentum Mill. `New Yorker') plants grown in a sandy loam soil in field lysimeters were subjected to four water table depth (WTD) treatments (0.3, 0.6, 0.8, and 1.0 m from the soil surface). In 1994, precipitation during the flowering stage was far above average and apparently led to waterlogging in the shallowest WTD treatment, while in the drier year (1993), the deepest WTD treatment suffered from drought stress. In general, over the 2 years, the 0.6-m WTD showed the best yields and largest fruit, while the 1.0-m WTD showed the lowest yields and smallest fruit. However, the incidence of catfacing, cracking, and sunscald was generally higher in the 0.6 m WTD treatment and lower in the 1.0-m WTD treatment. Furthermore, fruit firmness was generally greatest for the two deeper WTD than for the shallower WTD. To strike a balance between yield and quality, a WTD of between 0.6- and 0.8-m is recommended for tomato production on sandy loam soils.

In our study we aim to increase frost resistance and improve the yield and quality of apple is important in Turkey and world economy. Phenological and morphological observations, physiological and biochemical analyzes were carried out in apple (Malus domestica L.) plants. It was studied to determine the effects of foliar Salicylic acid (0, 500 ppm/plant and 1000 ppm/plant) on adaptation of this plant when exposed to freezing stress, the quality and yield. Leaf photosynthetic pigment contents, total protein amount, proline amount, superoxide dismutase and peroxidase enzymatic activities were measured. The study planned by random experimental design and statistical analysis of data with SPSS program (LSD test) were made. It was determined that fruit and shoot numbers were increased in samples exposed to 500 ppm salicylic acid and while fruit weights were increased in samples exposed to 500 ppm and 1000 ppm salicylic acid compared to the control. Also, colour of plants were darkened. Chla, chlb, total chl, proline, superoxide dismutase and peroxidase amounts were increased significantly compared to the control group. Increases occured in the carotenoid and the protein amounts are not significant statistically. In the light of obtained data, foliar application of salicylic acid were found to reduce the effects of freezing stress and to increase the yield and quality of apple plants.

This investigation was carried out during the two summer seasons of 2015 and2016 in sandy soil on potato culitvar "Sante" to study the effect of using 100%compost (15 t/fed.) and 50% compost + nitrogen fixing bacteria (Azotobacter, andPseudomonas alone or together) on potato yield and quality as compared to theconventional mineral fertilization (120-75-150 kg/fed. NPK + 5 toncompost/fed.(control)). No significant differences in tubers yield/fed. were detectedbetween mineral fertilization (control) and using 100% compost (15t/fed).However, control treatment significantly produced a high yield per feddan,more than using 50% compost + any biofertilizer treatment.Using composttreatment at 15 t/fed.execeed all biofertilizer treatments in marketable yield in bothseasons, but without significant differences as compared with mineral fertilization(control).No significant differences in tuber dray matter and content of starch intuber were found between using compost treatment at 15 ton/fed. and mineralfertilization treatment (control)in both seasons. Nevertheless, application of 50%compost+ 4 applications of Azotobacter and Pseudomonas had the highest tuberconcentrations of starch and nitrogen with significant differences as compared withthe mineral fertilization.Using50% compost + 4 applications of Azotobacter orPseudomonas or both (Azotobacter + Pseudomonas )and application of 100%compost caused producing potato tubers with the lowest concentration of nitratewith significant differences as compared with the mineral fertilization. Nosignificant differences were detected between mineral and organic fertilizersconcerning P and K concentrations in tubers.

N Rates

Processing tomato is the second most important worldwide cash crop, generally produced in high-input systems. However, fruit yield and quality are affected by agronomic management, particularly nitrogen (N) fertilization, whose application to indeterminate growth genotypes for canning has yet to be investigated in depth. Hence, the objective of this work was to assess the effects of different N rates (0, 50, 125, 200, 275, and 350 kg ha−1) on fruit yield and quality characteristics of processing tomato ‘San Marzano’ landrace. The results of our study showed that 125 and 200 kg of N ha−1 are the most appropriate rates in soil with high fertility, ensuring the highest values of marketable yield and brix yield. However, plants fertilized with 125 kg of N ha−1 attained higher values of N efficiency and fruit K and P concentrations than plants fertilized with 200 kg of N ha−1. Our results suggest that overdoses of N supplies negatively affected fruit yield and quality of San Marzano landrace grown in high soil fertility conditions, also reducing the agricultural sustainability. Hence, specific agronomic protocol and extension services are required to optimally manage tomato crop systems.

Moxibustion has been used to treat various types of disease. However, there is still insufficient evidence regarding its effectiveness. This study was performed to summarize and evaluate the effectiveness of moxibustion. A search was performed for all randomized controlled trials in PubMed between January 1998 and July 2008 with no language restriction. The results yielded 47 trials in which six moxibustion types were applied to 36 diseases ranging from breech presentation to digestive disorders. Moxibustion was compared to three types of control group: general care, Oriental medical therapies or waiting list. Moxibustion was superior to the control in 14 out of 54 control groups in 46 studies. There were no significant differences among groups in 7 studies, and the outcome direction was not determined in 33 studies. Seven studies were included in a meta-analysis. Moxibustion was more effective than medication in two ulcerative colitis studies (relative risk (95% CI), 2.20 (1.37, 3.52),P= .001,I2= 0%). Overall, our results did not support the effectiveness of moxibustion in specific diseases due to the limited number and low quality of the studies and inadequate use of controls. In order to provide appropriate evidence regarding the effectiveness of moxibustion, more rigorous clinical trials using appropriate controls are warranted.

Objective: To compare two breathing exercises (Buteyko and pranayama) with a control group in patients with asthma. Design: Randomized controlled trial. Subjects: One hundred and twenty subjects were randomized to three groups through block randomization. Subjects with an Asthma Quality of Life Questionnaire score <5.5 participated in the study. Setting: Outpatient pulmonary medicine department. Interventions: Subjects in the Buteyko and pranayama groups were trained for 3–5 days and instructed to practise the exercises for 15 minutes twice daily, and for three months duration. The control group underwent routine pharmacological management during the study period. Outcome measures: Asthma Quality of Life Questionnaire, Asthma Control Questionnaire and pulmonary function test. Results: The baseline characteristics were similar in all three groups. Post intervention, the Buteyko group showed better trends of improvement (mean (95% confidence interval), P-value) in total Asthma Quality of Life Questionnaire score than the pranayama (0.47 (–0.008–0.95), P = 0.056) and control groups (0.97 (0.48–1.46), P = 0.0001). In comparison between the pranayama and control groups, pranayama showed significant improvement (0.50 (0.01–0.98), P = 0.042) in total Asthma Quality of Life Questionnaire score. Conclusion: The Buteyko group showed better trends of improvement in quality of life and asthma control than the group performing the pranayama breathing exercise.

Growth Development

Summary. The effect of plant density on growth, development, yield and quality of kabocha (buttercup squash) (Cucurbita maxima) was examined during 1992–93, at a field site in Cambridge, Tasmania. Plant densities ranged between 0.5 and 4.7 plants/m2. Marketable and total yields were fitted to a yield–density model. Total yield followed an asymptotic trend, approaching 33 t/ha at 4.7 plants/m2, while marketable yield had a parabolic relationship with density. Marketable yield increased to a maximum of 18 t/ha at 1.1 plants/m2, while declining at higher densities because of increased numbers of undersized fruit. Yield of vine marked and callused fruit did not vary with density, but represented a significant proportion of the total yield at all densities. High plant density reduced vegetative growth per plant due to competition for limited resources; as shown by decreased leaf area, number and length of vines, and plant dry weight. Yield tended to decline at high densities because of fewer female flowers and increased fruit abortion per plant. Plants at low densities had more vegetative growth but decreased yields, as increased abortion of fruit relative to the higher plant densities left only 1–2 large fruit per plant. Economic returns varied with plant density. At high densities, variable costs increased (particularly due to high seed cost) while gross income declined reflecting the relationship between marketable yield and plant density. The gross margin therefore declined at high densities.
