Abstract

The study was under taken in Jodhpur district of Rajasthan. The district was selected purposively, as production under cumin crop was maximum in this district. Secondary data were used to compute the correlation co-efficient between arrivals and prices. Monthly data on arrivals and prices were taken for the period 2005-06 to 2009-10. It was noted that 63 per cent cumin produce arrived in the first quarter (March-May) of the year. The arrivals were 17.93, 8.54 and 10.02 per cent in the second, third and fourth quarters, respectively. Farmers got 10.36 per cent higher price by selling cumin in the second quarter over the post harvest season (peak season or first quarter). Sale of cumin in the third and fourth quarters of the year was not found advantageous. The correlation co-efficient between monthly wholesale prices and arrivals of cumin in the corresponding months and in the subsequent months were -0.578 and -0.588, showing that there existed inverse relationship between the two. The value of correlation co-efficient was estimated to be higher for the subsequent months than for the corresponding months. The value of correlation co-efficient between yearly arrivals and prices of cumin were negative in four years and positive only in one year out of the five years study period. This indicated that prices of cumin were not only affected by arrivals, but were also affected by factors such as demand, export-potential and seasonality of the crop.

Abstract

Mineralogical and petrochemical characteristics of the differentiated sill, occurring at the highest horizon of Morar Stage, Gwalior System (Cuddapah age), around the city of Gwalior, Madhya Pradesh, are detailed. Petrographically the sill, composed of dolerite which is sparsly porphyritic, tends to be quartz dolerite in higher levels. The occurrence of micropegmatitic texture is proportional to the amount of hornblende present in the rock. Chemical nature of the chilled margin reveals that the undifferentiated magma was tholeiitic. Differentiation in the sill is of limited extent and is considered to be the result of the combined processes of fractional crystallisation, crystal settling and mild convectional currents.

Abstract

In this paper the geometrically nonlinear equation of motion has been used to analyse the vibration of uniform rod having different axial stresses in different part. In particular the effect of axial stress on the resonant frequency for axial, flexural and torsional vibration of uniform rod restrained at both end has been investigated.

Abstract

As a transducer of the environmental factors the pineal gland, together with the metabolically active thyroid gland, plays a major role in control of reproduction during different times of the year, in response to the changing environmental conditions of the tropical zone unlike in the temperate zone. Our avian model P. asiatica is a long day breeder. It is reproductively active during summer and quiescent during winter months. In this study we investigated the role of thyroid gland super-imposed by melatonin in the regulation of the annual male reproduction in this bird. The metabolically active thyroid gland presented a functional parallelism with the testicular activity suggesting that thyroid hormone is essential for reproductive activity and related metabolic energy for avian species. Our data also suggest an inhibitory effect of melatonin on thyroid gland function [weight, thyroxine (T3/T4) level and thymidine kinase activity, THK] both during active and inactive phases of the reproductive cycle. However, this inhibitory effect was less evident during the active phase. The low level of melatonin during the reproductively active phase might be due to long days of summer which prevented the birds from being hyperthyroidic. Therefore, we suggest that the level of melatonin serves as a physiological check to control the seasonal reproductive activities of gonads and thyroid which synergistically play most important physiological roles in energy metabolism of these seasonally breeding bird P. asiatica.

Abstract

A study on varietal evaluation in taro for growth, yield and quality attributes was carried out in a replicated experiment and morphological and chemical analysis was done. Significant differences were recorded for all the characteristics studied. 'Panchmukhi' recorded highest plant height (179.33cm), petiole length (153.11cm), petiole breadth (13.87mm) and leaf size (3095.67cm2), LAI (1.14), corm length (152.41mm) and breadth (107.77mm), average corm weight (1500.00g) and corm yield (20.00t/ha). 'C-3' recorded maximum (15.00) petiole number and cormel length (85.93mm). Cormel yield (15.29t/ha), total yield (25.92t/ha) and number of cormels per plant (30.33) was found to be maximum in cv. White Gouriya. 'ML-2' recorded maximum (7.33) number of side shoots. Highest average cormel weight (72.85g) was maximum in cv. Arcol-7, and 'Arcol-5' recorded maximum (67.43mm) cormel breadth; the least blight incidence percentage (8.00) was recorded in 'Nayabungalow'. As for biochemical constituents, 'Nainital' recorded the highest (5.85%) total sugars, 'Kandha-5' exhibited the highest (34.67%) starch content and 'Nadia Local' with showed highest levels of oxalic acid (1.05mg/100g). Highest dry matter content (27.50%) was recorded in cvs. KCA-1 and Panchmukhi, while the highest moisture percentage (82.83) was recorded in 'IG Coll-5'.

Abstract

A field experiment was conducted during Rabi season of 2010-11 at Students' Instructional Farm of C.S Azad University of Agriculture and Technology, Kanpur. six crop biomass viz., mustard, field pea, sorghum, maize, rice and wheat straws were incorporated in soil before sowing and their allelopathic potential was compared with weed free and unweeded treatments and analysed on germination and growth of weeds in wheat crop. The crop growth parameters, yield attributes, yield and economics of wheat were also computed. The results obtained shown that mustard straw, sorghum straw and maize straw were more effective to suppress weed germination and growth. The application of mustard straw before sowing registered maximum grain yield of wheat (42.0 q/ha) followed by sorghum straw (41.33 q/ha), maize straw (40.66 q/ha), field pea straw (38.75 q/ha), wheat straw (35.83 q/ha), paddy straw (35.66 q/ha) and minimum grain yield (33.58 q/ha) was noticed in unweeded control treatment. The incorporation of mustard straw, sorghum straw and maize straw registered 25.07 per cent, 23.03 per cent and 21.08 per cent, respectively more grain yield than unweeded control treatment. Allowing weed growth though out crop growth period in unweeded control treatment caused on an average 31.26 per cent reduction in grain yield of wheat i.e. 44.08 q/ha of wheat variety UP 2338 in control in plain zone of Uttar Pradesh.

Abstract

A field experiment was conducted at Kanpur (Uttar Pradesh) during Rabi 2010-11 to evaluate the performance of 3 field pea varieties at different row spacings with uniform plant spacing 10 cm within row. The results revealed that variety 'indra' gave highest of 18.84 q/ha grain yield, 20.70 q/ha straw yield, Rs. 18008/ha net return and 0.76 B:C ratio. It was followed by variety 'Sapna', while variety 'Jai' remained at bottom Among row spacings, 15 cm recorded highest values of 19.20 q/ha grain yield, 20.89 q/ha straw yield and Rs, 17695/ha net return. Benefit : cost ratio was computed highest of 0.75 in 20 cm row spacing. The row spacing of 15 cm and 20 cm were found at par in all respect, but 25 cm row spacing performed significantly poorest. Varieties x row spacing interaction was not found significant. However, the combination of variety 'indra' and 15 cm row spacing gave highest seed yield of 19.68 q/ha and earned maximum net return of rs. 18749/ha.
