Cumulative and Residual Effects of Paclobutrazol on Growth, Yield and Fruit Quality of 'Alphonso' Mango

A field experiment was conducted during 1996 to 2002 at Indian Institute of Horticultural Research, Bangalore, to study the cumulative and residual effects of paclobutrazol (PBZ) application on shoot vigour, flowering and fruit yield of seventeen years old 'Alphonso' mango trees. Foliar sprays of the chemical at 500, 1000 or 2000 ppm or soil drench at 5 or 10 g a. i. per tree was given during September for three consecutive years and the residual effects were observed for three more subsequent years. Application of PBZ as soil drench was more effective than its foliar spray and doubled fruit yield during the six years. Chemical parameters of fruits such as TSS and acidity were not affected by the treatments but average weight of a fruit was less in the case of PBZ treatments. Residual influence of this chemical, when applied as soil drench, persisted in the three years following the discontinuation of application for three consecutive years, indicating the scope for skipping the application of PBZ or tapering down its dose after three years of its continuous application. From the results of this study, application of paclobutrazol at 5 g a.i. per tree as soil drench for three consecutive years and then its discontinuation for the subsequent three years appears to be most appropriate for 'Alphonso' mango trees in the age group of about 15 to 25 years

Effect of Pruning and Chemicals on Flowering and Fruit Yield in Mango Cv. Alphonso

A field trial was conducted from 2005 to 2009 on pruning and spray of various chemicals to study their effects on flowering and fruit yield in 'Alphonso' mango, at Indian Institute of Horticultural Research, Bangalore. Seven treatments were imposed, with pruning of fruited shoots as a common treatment, followed by chemical sprays and a control. Over the five years, flowering parameters (% vegetative, dormant or flowering shoots) were found to be non-significant among different treatments. Treatments increased fruit yield compared to control. The best treatment was T3 (Pruning+1% K2HPO4+1% KNO3 spray) which recorded mean fruit yield of 63.9 kg/plant, compared to a fruit yield of 33.0 k/ plant in control

Effect of Dose and Time of Paclobutrazol Application on the Flowering, Fruit Yield and Quality of Mango Cv. Alphonso

A field trial was conducted for eight years at Indian Institute of Horticulture Research, Bengaluru to find out the effect of dose and time of application of paclobutrazol (PBZ) on flowering, fruit yield and quality of 'Alphonso' mango. The percentages of flowering, vegetative and dormant shoots were affected by paclobutrazol application. Different dose and time of application of paclobutrazol increased the percentage of flowering shoots significantly and most pronounced effect was with treatment D1T2 (3ml/m canopy PBZ applied 90 days before bud break) which recorded 89.9% flowering shoots as compared to 73.8% in control treatment. Regarding fruit yield, maximum mean fruit yield of 22.0kg/plant was recorded with treatment D1T2 (3ml/m canopy PBZ applied 90 days before bud break) and least was with control (13.1kg/plant) which accounts for fruit yield increase of 67.9%. No particular trend was observed in respect of shoot length in different treatments. However in general, paclobutrazol application reduced the shoot length compared to control. With respect of fruit quality attributes, acidity and TSS were found to be non-significant among different treatments during different years. Average fruit weight was found to be significant during different years and paclobutrazol application reduced the average fruit size compared to control. Cost benefit ratio was maximum of 1:2.52 was with treatment 3ml/m canopy PBZ applied 90 days before bud break and least cost benefit ratio of 1:1.06 was with control

Studies on Rejuvenation of Old, Unproductive 'Alphonso' Mango Trees in Orchards

A field trial on pruning was conducted from 2004 to 2009 to induce rejuvenation of twenty six year old, unproductive 'Alphonso' mango trees, at Indian Institute of Horticultural Research, Bangalore. In the study, three treatments imposed comprised of two pruning treatments, namely 30cm and 45cm pruning of third order branches from the point of origin, and a control (no pruning). Pruning increased the mean cumulative fruit yield for four years, which was almost double that of control, although the two pruning treatments were on par. Maximum mean cumulative fruit yield (86.3kg/plant) was obtained with 30cm pruning, whereas control treatment recorded a fruit yield of 47.2kg/plant. Fruit quality attributes such as average fruit-weight, TSS, acidity and shelf-life were not affected by the two pruning treatments, for rejuvenation of 'Alphonso' mango

Empathy: simple and inevitable? Development education and narratives of African poverty

This article critically examines how the concept of empathy is mobilized in the rhetoric of development education, and explores different ways of conceptualizing empathy as a pedagogical ideal and an affective experience. Its premise is that the concept of empathy has been insufficiently probed within academia, even though paradigm shifts in development have made the concept central to development education. In reference to narratives of African poverty, the article critiques literature depicting empathy as simple or inevitable within development education. It seeks to open up new possibilities for conceptualizing a form of empathy that prioritizes nuance and self-reflexivity. The article intends to contribute to development education by advocating more respectful, dialogical and self-aware cross-cultural engagement

Marital quality in alcohol dependance syndrome: a comparative study between first time and repeatedly hospitalised patients

Background: Marital quality is considered as a significant part of social well-being. Poor marital quality adversely affects physical and mental health as well as the overall quality of life. Moreover, it can significantly affect the course of alcohol dependance syndrome. The aim this study was to compare the marital quality among patients with alcohol dependance syndrome who are admit-ted for the first time and patients with alcohol dependance syndrome (ADS) who are admitted for multiple times.Methods: The sample consisted of each 30 patients with alcohol dependance syndrome who are admitted for the first time and patients with alcohol dependance syndrome who are admitted for multiple times, diagnosed as per international classification of diseases-10 diagnostic criteria for research. The sample population was evaluated using Severity of Alcohol Dependence Questionnaire and The Marital Quality Scale. The data was analysed using SPSS-16.0.Results: The severity of alcohol dependance was found to be significantly higher in the repeatedly hospitalised group when compared to first time admitted patients with ADS (p<0.01). The repeatedly hospitalised patients are found to be having significantly poor Marital Quality in the domains of Understanding, Rejection, Satisfaction, Affection, Despair, Decision Making, Dominance, Self-Disclosure, Trust and Role Functioning, when compared to first time admitted patients (p<.001).Conclusions: How problem use of alcohol affect marital quality is not settled in research till date, though most of the studies suggest a negative correlation. There are contradictory hypotheses regarding the effects of alcohol use on marital quality. Our study showed that patients with severe degrees alcoholism and who are admitted repeatedly have poor marital quality when compared to patients with lesser severity of alcoholism and admitted for the first time in Indian context

Effect of Organic Nutrition Practices on Papaya (cv. Surya) Fruit Yield, Quality and Soil Health

A field experiment was conducted during 2005-07 at Indian Institute of Horticultural Research, Bangalore, on papaya cv. Surya with six organic treatments along with recommended dose of fertilizers and no manure/fertilizer application. Results indicated that crop growth and fruit yield were higher in inorganic fertilizer treatment (55 t ha1) compared to organic treatments (26.9 to 38 t ha-1). There was no significant variation in average fruit weight and TSS, but shelf life of the fruit was significantly higher in organic treatments (6.2 to 7.9 days) as compared to inorganic fertilizer treatment (5.1days). Among the treatments, application of 7 kg urban compost plant-1 or 10 kg FYM plant-1 was found to be ideal for improving soil health in terms of microbial population, and biochemical reaction compared to other treatments
