The validity of medium range weather forecast issued from National Centre for Medium Range Weather Forecast (NCMRWF) on various weather parameters for Keonjhar district of Odisha state during the period 2015 is discussed in this paper. The validity of weather forecast for monsoon and post-monsoon season was tested separately with real time data observed from station observatory. The ratio scores on Yes/No basis viz., Forecast Accuracy (ACC), Critical Success Index (CSI), Heidke Skill score (HSS), Hansen and Kuiper’s (HK) scores were used for testing of only rainfall prediction. The predicted rainfall on Yes/No basis for the total seasons was 85.1 per cent correct, whereas it was 92.1 per cent correct for monsoon and 88.6 per cent correct for premonsoon period. The weather forecast for other parameters was tested with Critical Values for Error Structure as suggested by NCMRWF. On annual basis, the prediction of cumulative rainfall (84.6%), rainfall ( 77.7%), Total cloud cover (61.6 %), and Tmin (52.2 %) were having maximum correct events, whereas the predicted Wind direction (63.2 %), RH I (36.3%) and Wind speed (35.0 %) were having maximum number of failure events. On seasonal basis, the predictions for rain (83.5%), Cumulative rainfall (79.6%), wind speed (44.8 %) and total cloud cover (44.6%) during monsoon period and cumulative rainfall (88.7%), rainfall (84.9%), wind speed (51.2%), and Tmin (50.4%) during premonsoon period were having higher percentage of correct events. However, the wind direction (71.1%) and RH II (60.6%) during monsoon and wind direction (53.6 %) and RH II (52.9%) during post monsoon period were having maximum number of failure events. The value (0.89) of co-efficient of determination (r) for rainfall during monsoon period indicated that the values of predicted rainfall were almost matching with the observed ones. It means that prediction of rainfall are near to accurate. The values of co-efficient of determination r = 0.93 in the regression analysis during pre monsoon period indicated accuracy in prediction of minimum temperature. The accurate weather forecasting with respect to various weather parameters is important as this can be used to facilitate the farmers to make broad decision on the crop management operations.

The sweet potato weevil, Cylas formicarius, constitutes a major constraint to sweet potato production and utilization in Africa. Host plant resistance/tolerance, mulching and varying harvesting dates could provide an approach that fits well into an integrated pest management programme of this insect pest. In this study, a trial was conducted to evaluate the effect of host plant, mulching with freshly harvested, dried and chopped up aerial parts of elephant grass ( Panicum maximum), and the manipulation of harvesting date, on crop damage by the sweet potato weevil. Cylas formicarius incidence was observed to decrease with increase in mulching level. Also, significant cultivar variation with respect to Cylas formicarius tuber damage and the total number of tubers produced were recorded. Karur local (White) and Arun (White) were observed to be significantly less susceptible to the sweetpotato weevil. Harvesting date was also significantly different, with respect to the number of damaged tubers. More tubers were damaged when harvesting was delayed. Hence, using Karur local (White) or Arun (White), coupled with mulching at the rate of 3-5t/ha and harvesting at 104 DAP resulted in increased number of tubers and reduced sweetpotato weevil infestation in the field.

The socio-economic status of eight villages with a total of 521 households surveyed during the study, including 2820 members in different groups and community. The average family size was reported to be 5.41 members per family. During the survey of villages, it was found that the adult literacy rate in male was 51.19 per cent as comparison to female literacy rate 48.80 per cent, respectively. In the livestock of the eight villages the various categories of livestock the buffaloes were the maximum 57.82 per cent followed by sheep/goat 26.30 per cent. The average daily fuel wood consumption during summer and winter in different villages varied from 83.41 kg/day/village to 535.40 kg/day/village in summer and 150.70 kg/day/village to 757.05 kg/day/village in winter which are supplemented by existing agroforestry upto considerable extent. The utilization of fodder tree varied from 301.05 kg/day/village to 1009.15 kg/day/village in the summer and 650.50 kg/day/village to 2011.50 kg/day/village in the winter season which is also supplemented by traditional agroforestry trees in a sizeable limit. The land holding size ranged from 0.03 to 5.6 ha per family with 77.9 per cent families under marginal category, 19.05 per cent under small category and -3.04 per cent families comprised of mediumlarge landholding size.

The study was carried out to estimate the price spread and marketing efficiency in the marketing of cauliflower in different channels by using different tools such as price spread, marketing costs, marketing margins and marketing efficiency . As cauliflower is a market oriented crop, on an average about 93 per cent of production was marketed, while negligible portion was utilized for other purposes. The producer to wholesaler-cum-commission agent to retailer to consumer was the major marketing channel as more that 50 per cent of cauliflower moved through this route. The total cost in marketing of cauliflower per quintal was Rs. 337.85 which was 43.19 per cent of the consumers' rupee. Amongst it the highest marketing cost was observed in retailers which accounted for as (Rs.129.25) followed by wholesaler-cum-commission agent (Rs.70.63) and growers (Rs.19.35) per quintal. Results also indicated that commission was the major marketing cost possessed by wholesaler-cum-commission agent while retailer possessed damage cost. The margins in cauliflower marketing amounted to Rs. 224.99 per quintal which was 28.76 per cent of consumers' rupee. The producer's share in consumer's rupee was 43.19 per cent. The marketing efficiency was lower than unity (0.77).Market information and provision of logistic support need to be made available to the cauliflower growers to improve existing marketing system. Further, promotion of vegetable co-operatives or vegetable producers' co-operatives can go a long way to make the existing marketing system of cauliflowers more efficient and farmers centric.

The present study was conducted in Marathwada region of Maharashtra state. Present study was carried out in randomly selected Parbhani district. Four talukas was selected purposely from Parbhani district by considering highest area and production of the soybean crop namely viz., Purana, Palam, Parbhani and Gangakhed. Three villages from each taluka were selected randomly, thus, the make12 villages were selected for study. Ten respondents were selected from each village with the help of those who have cultivating soybean crop on his farm was selected randomly. Thus, the total 120 respondents were selected for the study. The major soybean crops selected for study because soybean crop is infested by number of weeds like Shippi (Echinochloa crus-galli ), Kena (Commelina benghalensis ), Dudhi (Euhorbia spp.), Hazardani (phyllanthus niruri), Nagarmotha (Cyperus rotundus), Hariyali (Cynodon dactylon) etc. which causes loss of farmer upto 40 to 60 per cent in yield, weeds in soybean can be effectively controlled by using integrated weed management practices. Thus, the study was conducted for considering the problem of weed control in soybean crop. Ex-post facto research design was used for present study. The data were collected with the help of personal interview method with the help of interview schedule. It is revealed Table 1 that 69.17 per cent of the respondents were from medium farming experience, 45 per cent respondent were educated upto secondary (middle) school level, 35.83 per cent had small size land holding (upto 2 ha), 89.17 per cent of the respondents engaged in only agriculture, 78.34 per cent of the respondents were from medium income i.e. (Rs. 77103 to 409000) group, 50.84 per cent of the respondents had medium social participation, 62.50 per cent of the respondents used medium sources of information, 59.17 per cent of the respondents had medium extension contact, 59.17 per cent of the respondents had medium level of market orientation, 61.67 per cent, of the respondents had medium level of risk orientation and 62.50 per cent of the respondents had medium level of knowledge.Education, land holding, occupation, annual income, sources of information, extension contact and market orientation and risk orientation had significant relationship with adoption of integrated weed management practices.

The study was carried out to determine the farmers adoption behaviour on wheat production technologies. The farmers were selected from saline area of Gir Somnath district in Gujarat and were demonstrated production technology during 2011-12, 2012-13 and 2013-14. It was revealed that 36.8 per cent farmers fully adopted demonstrated wheat production technology. Whereas, 21.5 per cent farmers adopted partially.The major constraints observed in wheat production was salt affected soil as well as poor quality of irrigation water. In wheat, with salt affected soil, salt tolerant wheat variety (KRL-19) yielded 34 to 43 per cent higher yield than farmers' practice. The B:C ratio of demonstrated plots under salt affected soil were observed 4.05, 4.03 and 4.21, respectively during three years.

A field experiment was conducted to assess the growth and carbon sequestration potential of five fast growing trees namely Tectona grandis, Gmelina arborea, Dalbergia sissoo, Bambusa vulgaris var. vulgaris and Swietenia macrophylla. The saplings of these five species were planted and assessed for biometric, biomass production and carbon accumulation potential. Among the five tree species, Dalbergia sissoo and Bambusa vulgaris var. vulgaris were found to be superior interms of maximum height, basal diameter, biomass and biomass carbon. Gmelina arborea exhibited low height, basal diameter, biomass and biomass carbon. The per cent contribution of biomass carbon was higher in the stems of all the species followed by root, branches and leaves. The field study inferred that, Dalbergia sissoo and Bambusa vulgaris var. vulgaris performed well with higher biomass and biomass carbon productivity under dry land condition and hence these two species can be promoted for afforestation / reforestation of the wastelands in Tamil Nadu under protected irrigation conditions.
通过田间试验，研究了大构造木(Tectona grandis)、小檗(Gmelina arborea)、黄檀(Dalbergia sissoo)、普通竹(Bambusa vulgaris var. vulgaris)和大叶甜木(sweenia macrophylla) 5种速生乔木的生长和固碳潜力。对这5个树种的树苗进行了生物特征、生物量生产和碳积累潜力的评估。在5种树种中，黄檀(Dalbergia sissoo)和普通竹(Bambusa vulgaris var. vulgaris)在最大高度、基径、生物量和生物量碳方面均具有优势。Gmelina arborea表现出高度低,基底直径、生物量和生物量碳。生物量碳的贡献率在所有物种的茎中都较高，其次是根、枝和叶。野外研究表明，在旱地条件下，黄柏(Dalbergia sissoo)和普通竹(Bambusa vulgaris var. vulgaris)具有较高的生物量和生物量碳生产力，可作为泰米尔纳德邦保护灌溉条件下荒地造林的推广树种。
