Perhaps the best way to clarify my position for Dr. Magian is to consider the benefit/cost ratio of impedance audiometry for routine screening of children. (As a research tool I support its use strongly.) Let us first consider the benefit of routine screening and how firmly established this benefit is. The major benefit claimed is that tympanometry identifies eustachian tube dysfunction with greater sensitivity than other techniques. To quantitate this benefit one needs to know the proportion of children identified by this, but not by other, techniques.

ABSTRACT Introduction The correlation between middle ear pathology due to Eustachian tube dysfunction and nasal allergy has been a topic of debate since long. Studies of the pathogenesis of otitis media have identified interactions among infection, allergic reactions and Eustachian tube dysfunction. AIMS- The aim of this study was to evaluate the relationship between Eustachian tube dysfunction and nasal allergy and to evaluate the efficacy of oral steroids and intranasal steroidal spray on Eustachian tube dysfunction. Materials and methods The patients were diagnosed according to the diagnostic criteria of allergic rhinitis. A total of 50 patients having moderate/severe symptoms who had not taken any treatment for allergic rhinitis in the past 6 weeks with deranged middle ear function were included in the study. Group I patients were given Prednisolone, 30 mg once daily for 10 days in tapering dose along with intranasal steroid spray for 6 weeks. Group II patients were given only intranasal steroid spray for 6 weeks. Impedance audiometry was repeated at the end of 6 weeks and results were statistically analyzed. Result This study demonstrated the outcome of systemic steroids and intranasal steroidal spray in the treatment of middle ear dysfunction. In our study impedance audiometry was done at the start of study and showed type B tympanogram in 36% ears in group I and 21% in group II and type C tympanogram in 60% in group I and 50% in group II. Impedance audiometry was repeated at 10 days of treatment and showed reversal to type A curve in 26% of ears in group I and 14% of ears in group II. Impedance audiometry at the end of treatment demonstrated reversal to type A tympanogram in 64% of ears in group I and 48 % of ears in group II.

The Imidacloprid insecticide, Gaucho 70 WS at 1.5, 2.5, 3.5, 4.5 and 5.5 g/kg seed was used as seed treatment and monocrotophos 40 WSC at 1120 ml/ha was applied as foliar spray on CB9 cotton cultivar to suppress aphid, whitefly and thrips, and impact on their natural enemies during 2008-2011 at the Regional Cotton Research Station, Dinajpur, Bangladesh. The activity of natural enemies, such as ladybird beetle, lacewing, syrphid, and spider population on the sucking pests attacking cotton cultivar CB9 and yield of cotton were recorded. Imidacloprid significantly reduced aphid, whitefly, and thrips population on cotton crops compared to untreated control or foliar spray of monocrotophos 40 WSC at 1120 ml/ha. Ladybird beetles, lacewings, syrphids, and spiders were abundant in the field but their population decreased in the treated plots compared to untreated control. The CB9 cotton cultivar produced significantly higher yield (1.73 t/ha) with a benefit cost ratio 12.47 when seeds were treated with Imidacloprid at 5.5 g/kg fuzzy seed. This study indicated that Imidacloprid (Gaucho 70 WS) used as a seed treatment may be suggested to the cotton growers for controlling sucking pests. Bangladesh J. Agril.

Rice Processing

Rice production and processing over the years has been on an increase with more small holders entering the business. This study on profitability of processing and marketing of small scale rice processors had as objective to analyse the profitability levels of rice processing and marketing by small scale processors, determine the value added to the commodity at each stage  and also identify the constraints faced by these processors. The study used primary data collected using well-structured questionnaire from millers only, miller traders for white/parboiled rice through a multistage sampling technique. Results showed that the net processing income (3,151,201), value added (8,147,456) and efficiency (138) for miller-traders of white rice was highest, followed by miller-traders for parboiled rice and lastly millers only. Results further showed that millers only had Benefit/cost ratio of 0.4 indicating that milling only is not profitable due to small quantities milled, and high fixed cost. Miller-traders for parboiled rice had a benefit/cost ratio of 2.3 implying that their venture is most profitable. Based on the results, it was recommended that millers only should purchase large quantities of paddy to enable them reduce the overhead cost. Also the services of parboilers should reflect in the sales price of parboiled rice so that the parboiling services can be paid for.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

In Haryana (India) cotton is generally sown with conventional tillage practices witnesses poor germination and plant establishment. Poor plant stand is attributed by burning of emerging plants due to very high temperature at the time of planting, which is further worsen by crust formation due to pre-monsoon showers. Keeping these points in view, an experiment was conducted with farmers' participatory research mode in village Hajwana of Kaithal district. Cotton sown with zero tillage technique resulted in approximately five percent higher yield i.e. 136.3 kg ha-1 over conventional tillage. Mean returns over variable cost of all the three years were 10.8 percent i.e. Rs. 11794 ha-1 more in zero tillage over conventional tillage. Benefit: cost ratio were 3.86, 3.86 and 4.61 in conventional method of planting, bed planting and zero tillage technique, respectively. Zero tillage planting of cotton reduced fuel consumption by 93.4 % and 91.7 % compared to bed planting and conventional planting respectively.
