"Rice is Life" aptly describes the importance of rice in food and nutritional security, particularly for the Asian countries including India. For achieving and maintaining self sufficiency in rice, in view of ever increasing population, rice production has to be enhanced on a continual basis. The appropriate relationship between source sink and their capacity is essential to determine the yield especially in rice. In present investigation the impact of source limitation on assimilate partitioning and yield attributes to optimize the production potential and physiological basis of higher yield contributing traits in the ten genotypes. It was observed that the impact of source limitation was more pronounced in var. Dagad Desi, ARB-6, Ananda which exhibited maximum stability for grain yield. It was mainly due to the proline association with the morphological and phenological parameters as well as physiological behaviour, which ultimately raised growth rate, whereas in (control) Mahamaya and Swarna performed well. Yield was inversely related with ATR. Among cultivars, yield was directly correlated with maximum ATR under stress conditions and cultivar Swarna/ IR and Swarna maintained better translocation under stress than did the other cultivars. It clearly indicates that the defoliation of (100% leaf removal) plays significant positive contribution in balancing source sink, relatively which influenced the yield of crop and facilitating the better harvesting. Thus, it can be clearly suggested that the leaves (source) could determine the degree of plant performance and control the level of filled grain in rice.

A field trial was carried out for two years to ascertain performance of marigold (var. Pusa Narangi) planted at three spacings and on six different dates at bimonthly interval i.e. on first day of March, May, July, September, November and January. The crop planted on 1st March showed early flowering compared to other planting dates. The best performance with respect to flower size, weight and number of flowers per plant was recorded with 1 st September planting. The highest number of branches and plant canopy spread were attained with May and July plantings. In both the years wider spacing of 40 cm × 40 cm produced best results with respect to maximum flower diameter, weight of individual flower and number of flower per plant. However, the total best yield per unit area was higher when the crop was planted on 1 st September at 40cm × 20 cm spacing.

Sugarcane is an important agro industry crop in India plays a pivotal role in national economic by contributing 1.9 per cent to gross domestic product, form an important component in cropping pattern of the sugarcane growers, provide an essential commodity in the form of sugar and jiggery and solves the problem of green fodder for half of the year. The crop is cultivated in 5.03 million hectare producing more than 342 million tones with a productivity of about 70 tonnes per hectare. In India, Uttar Pradesh contributes about 47 per cent in area (1.98 million hectare) and production (117.14 million tonnes) with 47.36 per cent of total sugarcane production. The present study was attempt on, to work out the cost and returns of sugarcane production for different size group of farms in the study area. From the purposively selected district and block on the basis of highest area under the crop. Four villages were selected randomly from the selected block, a complete list of the farmers were prepared and than categorized into four categories i.e. marginal, small, medium and large. From the total sugarcane growers, 100 respondents were selected in probability proportion to their population, for the collection of data, suitable statistical tools were employed to meet the above objective. The cost of cultivation of sugarcane planted was Rs. 172679, in which share of operational cost, land rent and material costs was 38, 22 and 26 per cent, respectively. The cost of cultivation of sugarcane ratoon was to be Rs. 129752.65 with share of operational cost, land rent and material cost of 41, 29 and 14 per cent, respectively.

The study examined the extraction and consumption pattern of fuel wood, socio-economic and forest resource characteristics and their relationship with extraction and consumption of fuel wood in rural Kashmir. Sample villages and representative households were selected using multi-stage random sampling for field study through structured interviews and personal observations. Correlation and multiple regression analysis was carried out to establish the relationship between socioeconomic and forest resource parameters and fuel wood consumption. Results show that the total extraction of fuel wood in the sample villages was 224.64 tons annum -1 , which is mostly consumed in cooking (45.60%). Of the total extraction, 26.17 per cent was secured from forests and rest (73.83%) from other sources. All the independent variables put together had contributed to 78.60 per cent (R 2 = 0.786) variation on the fuel wood consumption and the key variables viz., family composition, size of land holding, housing status, frequency of forest visits and extent of agroforestry/homestead plantation had significant contribution in influencing the fuel wood consumption. The fuel wood flow from forests to the sample villages is excessive as compared to the national estimates, creating threats to the biodiversity conservation and ecological stability of the adjoining forests of the area. The over-utilization of forest biomass by the local populace is leading to a depletion of forest resources and diminished biomass productivity, which in turn induce socio-economic and livelihood stress. Therefore, some alternative interventions are required to be implemented efficiently to keep pace with the current development and future challenges.

An experiment was conducted at Horticulture Garden, Department of Horticulture, C.S. Azad University of Agriculture and Technology, Kanpur during two consecutive year. The main objective was to produce qualitative and quantative fruits yield of papaya for fetching good return with use of chemical and physical mutagens. The maximum fruit yield of papaya was recorded by 24.86 kg/plant with the use gamma irradiation 10 kr, followed by control (24.01 kg/plant). Application of EMS mutagen @ 0.2% and 0.4% gave fruits by 18.38 kg/plant and 18.64 kg/plant, respectively. It is worth while to mention here that the lower doses of chemical and physical mutagens use on papaya gave better response over the higher doses. The growth and yield trails was found in concordance to fruits yield of papaya.

The investigation on 'Flowering response of Dendrobium cv. EARSAKUL to plant growth promoters in different growing conditions' was conducted at College of Horticulture, Vellanikkara, Kerala. Results revealed that, among plant growth promoters, the treatment POP + OM + VW + PGPRE + Bone meal + GR (T 4 ) resulted in longer spike (31.34 cm), more flower count (6.54) and longer vase life (30.00 days), whereas, the treatment NPK + GR + OM + VW + PGPRE + Bone meal (T 6 ) was the best with respect to time taken for first flower opening (14.52 days) and number of spikes per plant (2.62) in six month old plants. In three year old plants, the treatment POP + OM + VW + PGPRE + Bone meal + GR (T 4 ) was the best with respect to time taken for flowering (283.91 days), days to last flower opening (10.98 days), number of spikes (2.63) and vase life (28.26 days), whereas, length of the spike (30.46 cm) and number of flowers (5.08) were the highest in the treatment NPK + GR + OM + VW + PGPRE + Bone meal (T 6 ). Among three systems of growing, top ventilated polyhouse (S 2 ) had maximum influence on flower characters. In interaction, the combination of POP + OM + VW + PGPRE + Bone meal + GR (T 4 ) and top ventilated polyhouse (S 2 ) was significantly superior in flower characters irrespective of the age of the plants.

In interaction, the combination of POP + OM + VW + PGPRE + Bone meal + GR (T 4 ) and top ventilated polyhouse (S 2 ) was significantly superior in flower characters irrespective of the age of the plants.","PeriodicalId":411017,"journal":{"name":"INTERNATIONAL JOURNAL OF FORESTRY AND CROP IMPROVEMENT","volume":"326 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120876938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Natural forest is the source of supplies of various plants of tuberous and roots importance that provides carbohydrates and some minerals and are often important ingredients in traditional medicines. They used as drought and famine foods, not only because they survive in low rainfall periods, but can also be an important source of water. Looking to the importance of wild tuberous crop in the tribal dominating region of the State an ethno botanical study was conducted to document and compile the wild edible tubers that had been observed and investigated in Central part of Bastar region of Chhattisgarh State. So that their importance, traditional uses could be realized. A total of 22 wild edible tubers were identified and recorded as food sources during the study period were Amorphophallus paeoniifolius, Asparagus racemosus, Chlorophytum borivilianum, Colocasia esculenta,Costus speciosus, Curculigo orchioides, Curcuma amada, Curcuma angustifolia, Curcuma caesia, Dendrocalamus strictus, Dioscorea alata, Dioscorea bulbifera, Dioscorea hispida, Dioscorea oppositifolia, Dioscorea pentaphylla, Dioscorea bulbifera var. pulchella, Hibiscus rugosus, Ipomoea batatas, Leea macrophylla, Pueraria tuberosa, Scirpus grossus, Urginea indica . Dioscorea or commonly known as yam was reported to be one of the major food sources in Bastar region. It was noticed that Dioscorea available as major tuber crops and highly utilized tuber species. The majority of villagers used Dioscorea in many ways in their life such as for food, medicinal purposes and fish poison. The 22 edible tuberous and root plants were belongs to the 13 families out of which Dioscoreaceae, Zingiberaceae, Liliaceae and Araceae had more than one identified plants whereas the families like Costaceae, Asparagaceae, Hypoxidaceae, Poaceae, Leeaceae, Fabaceae, Cyperaceae, Malvaceae, Convolvulaceae had only one edible tuber plant during period of study. The wild tubers are the dietary food and of seasonal resources of the tribals in forest dominating areas. Although the popularity of these wild tubers has declined, it is considered that special attention should be given to them in order to maintain and improve this important source of food supply in the area. This paper dealt with the wild edible tubers plant utilized by the tribal's of Bastar for their sustenance. The wild edible tubers plant of Bastar illustrated and documented for their utilization pattern.
