A STUDY ON ORGANIZATIONAL CLIMATE PERCEPTION BY VETERINARY OFFICERS(VOs) AND VETERINARY LIVESTOCK INSPECTORS(VLIs) OF THE DEPARTMENT OF ANIMAL HUSBANDRY AND VETERINARY SERVICE, KARNATAKA Sandika, A. L; Angadi, J. G; Hirevenkanagoudar, L.V; Basavaraj, H This study was conducted to assess the organizational climate perception by Veterinary Officers (VOs) and Veterinary Livestock Inspectors (VLIs) of the Department of Animal Husbandry and Veterinary Service (AH & VS) in Belgaum district of North Karnataka during 2005 / 06. Majority of VOs (55 .00%) and 45.00 percent of VLIs perceived the organizational climate as favourable. Whereas, the most favourable perception was observed with only 34.00 percent VOs and 15.00 percent VLIs. On the contrary, less favourable perception was noticed with relatively high percentage of VLIs (40.00%) compared to VOs (11.00%). Further, it was observed that there was significant difference between mean values of the organizational climate perception of VOs (106.6) and VLIs (96.25). Age, job experience, job involvement and job satisfaction had positive and significant association with organizational climate perception by both VOs and VLIs whereas, job stress had negative and significant relationship with organizational climate perception. The variables such as information seeking behavoiur, perceived work load and availability of facilities and resources had shown non significant relationship in case of VOs whereas, experience, training and perceived work load had a non-significant relationship with the level of organizational climate perception of VLIs. Provide adequate facilities, Implement an appropriate promotion scheme, increase the salary and salary increments were major suggestions expressed by VOs avd VLIs to improve the organizational climate of the department.

EVALUATING THE PERFORMANCE OF FARMER COMPANIES IN SRI LANKA: A CASE STUDY OF RIDI BENDI ELA FARMER COMPANY Esham, M; Usami, K Farmer companies in Sri Lanka were established with the view to accelerating commercialization in non-plantation agriculture. However, due to various constraints they have failed to achieve expected objectives. Hence, in this study, we review the potential of a successful farmer company from the aspects of farmer perception, farmer company management and performance. A field survey and secondary published data were used for the study. The study revealed that farmer perception of the farmer company as a service provider and awareness gap between shareholders and the farmer company coupled with restriction on share capital ownership limited the ability of the farmer company to expand the share capital and its commercial activities. Therefore, there is a need to strengthen the capital base of the farmer companies to enable the expansion of commercial activities and attract more farmer participation. In this regard, the active participation of the agribusiness industry should be sought considering the need to preserve the independence of the farmer company.

THE EFFECT OF SIX SUBSTRATES ON THE GROWTH AND YIELD OF AMERICAN OYSTER MUSHROOMS BASED ON JUNCAO TECHNOLOGY Rajapakse, J. C; Rubasingha, P; Dissanayake, N. N Mushroom cultivation in Sri Lanka is a popular cottage industry having oyster mushrooms as the most preferred variety. An investigation was carried out to study the suitability of five different plant substrates (dried banana leaves, coconut leaves, kakilla leaves (Dicranopteris dicnotonoma), paddy straw and sugar cane bagasses) for oyster mushroom cultivation in comparison with standard saw dust media as the control. Best substrate for oyster mushroom cultivation was adjudged by comparing the mycelial growth rate and the fruiting body yield values in different substrates. Although the highest mycelial growth rate was recorded in banana leaf substrate followed by paddy straw and bagasses mixtures, higher mushroom yields were recorded only in mixtures with paddy straw and bagasses which showed no significant difference to the control. Therefore it could be concluded that paddy straw and sugar cane bagasses are equally good substrates as the traditionally used saw dust media for oyster mushroom cultivation in Sri Lanka.

A COMPARISON OF METHODS USED IN ESTIMATING MISSING RAINFALL DATA De Silva, R. P; Dayawansa, N.D.K; Ratnasiri, M. D Precipitation or rainfall (in tropics) is an important climatic parameter and the studies on rainfall are commonly hampered due to lack of continuous data. To fill the gaps (missing observations) in data, several interpolation techniques are currently used. However, the lack of knowledge on the suitability of these methods for Sri Lanka is a practical problem. In view of this problem, this study is aimed at comparing a few selected methods used for the estimation of missing rainfall data with a new method introduced by the authors to determine their suitability in Sri Lankan context. The methods studied were Arithmetic Mean (Local Mean) method, Normal Ratio method and Inverse Distance method. The new method introduced by the authors is named as Aerial Precipitation Ratio method. In this approach, rain gauging stations where complete monthly rainfall data sets are available were selected in such a way that the selected stations represent each of the seven major Agro-ecological zones of Sri Lanka. This selection procedure of stations makes it possible to generalize the results to the entire country. The period of data ranged from 15 years in the case of mid country intermediate zone to 28 years Up country intermediate zone and Mid country wet zone. Subsequently, monthly rainfall data of each station were estimated using the data of surrounding stations based on the above selected methods so that actual data and the estimated data can be compared. Each estimated series was compared with the actual data series using different statistical comparison techniques. These comparisons include Descriptive Statistics of Error, Root Mean Square Error, Mean Absolute Percentage of Error and Correlation Coefficient. Results of the study show that the Inverse Distance method is the most suitable method for all three Low-country zones (wet, intermediate, and dry). However, for Mid-country and Upcountry Intermediate zones, Normal Ratio method is the most suitable method. Further, Arithmetic Mean method is more appropriate for Upcountry Wet zone while Aerial Precipitation Ratio method is more suitable for Mid-country Wet zone.
