Abstract: The present study was conducted to find out the effect of media on germination and vigour of Moringa oleifera. The seeds of Moringa oleifera were sown in different media such as top of paper (TP), between paper (BP), sand (S) and top of sand (TS). The maximum germination percent and high vigour index was recorded in the top of sand (TS) medium. Being a large size seed, it gave good results in sand (S) and top of paper (TP) also. It is evident from the results that the germination value of seed has little difference in both the media such as top of paper (TP) and top of sand (TS). Sand it self also proved a good medium and inexpensive other than. So, it is recommended that top of sand (TS) is good medium for testing the seed of Moringa oleifera in controlled condition.

Abstract: Silk, a highly priced agricultural commodity, accounts for about 0.2% of the total world production of textile fiber. Since sericulture stands next to agriculture for rural employment in India, it becomes a matter of concern to examine the sericulture production trend over the years and reasons for slow growth. The data for the study period 1980-81 to 2005-06 collected from Annual Reports of Central Silk Board were partitioned in two equal halves, the first 13 years (1980-81 to 1992-93) and next 13 years (1993-094 to 2005-06). Data were analyzed using Linear and Exponential model for comparison of production trend during first half and second half of the period of analysis. The trend speaks of faster growth rate during first half in comparison to 2nd half. The declining growth rate is going to affect the silk industry at national and international levels. Production trends are different for different silk types. These are required to be discussed in view of developing strategies for reaching new height of production and to withstand the global competition.

Abstract: Forty provenances of Shisham (Dalbergia sissoo) were screened against Ganoderma root rot under the natural conditions in a randomized block design. Variations to the extent of mortality and plants showing initial root rot symptoms were recorded. None of the provenance remained disease free. However, least mortality (2.0%) was recorded in Barielly provenance followed by 4.2 percent in Rampur provenance and rated as resistant to Ganoderma root rot. In the plantation of Rampur and Barielly provenances, 4.2 and 10.4 percent plants, respectively showed initial symptoms of root rot. Highest mortality (33.4%) was recorded in Banaras provenance followed by 29.2 percent in each Nazibabad and Etawah provenances. In terms of height and diameter, Kankai provenance was rated as best but it was moderately susceptible (14.6% tree mortality) to Ganoderma root rot. Provenance Rampur, which was rated as resistant with 2.0 percent tree mortality, was fifth best in terms of plant height and diameter at breast height.

Abstract: Analysis of two medicinal plants, Andrographis paniculata (Andrographolide) and Oroxylum indicum (mixture of oroxylin A & chrysin) content was carried out under different fertilizer treatments and at different physiological stages of plants. Total ash, water-soluble ash, acid insoluble ash, alcohol soluble extractives and water-soluble extractives for the above plant species were estimated alongwith thin layer chromatography examination. Maximum andrographolide content of 2.0% was found in 120 days old plants and among the treatments given to plants, the chemical fertilizer treatment influenced the Andrographolide, alcohol soluble extractive and water-soluble extractive. In case of Oroxylum indicum, all other evaluated compounds other than oroxylin-A and chrysin content were found to be almost similar whereas oroxylin-A and chrysin content was found maximum in mature tree root bark i.e. 0.7%. The results of present study show that fertilizer treatments given to plants and time of harvesting affect the chemical constituents of plants.

Abstract: The daily net ecosystem CO2 exchange, diurnal pattern of net CO2 exchange and ecosystem respiration of Cenchrus ciliaris grasslnad in semi-arid region were studied during July 2008-June 2009 using eddy covariance measurement. The active season during which daily net CO2 uptake was observed corresponded with the wet season which lasted for 7 months. High CO2 uptake was observed during September to December. Pulses in CO2 release occurred with the rewetting of the soil by summer rain events during dry period. The amplitude of daytime and noctural ecosystem CO2 exchange increase by many folds during the active season when compared with the dry season. Ecosystem respiration exhibits strong positive relationship with soil moisture (r2= 0.768) but negatively correlated with soil temperature (r2=0.498). The seasonal changes in net ecosystem exchange and ecosystem respiration were strongly regulated by soil moisture therefore, the phase of the net uptake and release of CO2 by the ecosystem depend on the balance between the wet season and the dry season.

Keywords: Economics, organic farming, productivity, soil quality
Abstract: A survey was made on certified organic farms in the country to ascertain the real benefits and feasibility of organic farming in terms of the production potential, economics and soil health in comparison to the conventional farms. The study revealed that organic farming, in spite of the reduction in crop productivity by 9.2%, provided higher net profit to farmers by 22.0% compared to conventional farming. This was mainly due to the availability of premium price (20-40%) for the certified organic produce and reduction in the cost of cultivation by 11.7%. In cases, where such premium prices were not available and the cost of cultivation was higher primarily due to purchased off-farm inputs, organic farming was not found economically feasible. However, there was an overall improvement in soil quality in terms of various parameters, viz. physical, chemical, biological properties, availability of macro-and micronutrients, indicating an enhanced soil health and sustainability of crop production in organic farming systems.
