Planting time is one of the effective means of improving cut flower output under open field conditions. A field experiment was carried out on gerbera with eight planting dates starting from 1st August to 15th November at fortnightly interval during 2010 to 2013. Difference in planting time produced significant difference in performance of gerbera due to variation of climatic condition. Planting on 1st September showed the best response in terms of plant height (28.35 cm), number of leaves/plant (26.2), flower diameter (11.55 cm) flower stalk length (65.52 cm), number of flower/plant/year (29.85) and number of flower/m2 (268.65) compared to rest of the planting dates. The study clearly suggested that the best planting time for gerbera under open field condition in Bihar is beginning of September.Keywords

Global warming is steadily increasing and impacting on highly vulnerable developing countries. Agriculture which is an essential sector for most of developing countries contributing to climate change with greenhouse gas emissions (GHG) and suffering from the effects of climate change. The challenge of feeding the population and reducing agricultural GHG emissions requires the successful transfer of climate-friendly agricultural and land use practices to farmers serving adaptation and mitigation needs. Jute crop have the potential to absorb and fix carbon dioxide from the atmosphere, save for the carbon released back through the application of agro-chemical inputs and use of fossil fuels in the management of jute production systems. The paper reviews the relationship between carbon sequestration, jute crop management systems and the effects on greenhouse gases. This may help in identifying the point to improve environmental efficiency and accessing opportunities for carbon trading, contribute to the development of sustainable technologies to manage GHG emissions and global warming.Keywords

The field experiment was carried out during Rabi season of 2012-013 and 2013-14 at Indore (M.P) to find out the performance of different wheat and lentil inter and mixed cropping systems on the productivity and profitability of late sown wheat.Treatments tested were wheat sole, lentil sole, wheat (line sowing)+lentil (broadcasted), wheat (broadcasted)+lentil (line sowing), wheat+lentil (mixed sowing of 100% seed rates of both), wheat+lentil (mixed sowing of 50% seed rates of both), wheat+lentil (1:1 row ratio), wheat+lentil (2:1 row ratio), wheat+lentil (2:2 row ratio) and wheat+ lentil (3:1 row ratio). Results indicated that line sowing of wheat at 20 cm a part rows+broad cast sowing of lentil as @ 30 kg seed/ha recorded higher values of no. of fertile tillers/m2, length of spike (cm), number of spikelet/spike, grain yields (5.81 and 5.93 t/ha), biological yields (14.8 and 14.8 t/ha), wheat grain equivalent yields (5.94 and 5.99 t/ha) and land equivalent ratio (1.06 and 1.09) than wheat sole along with a bonus yield of lentil grain to the tune of 50 and 20 kg/ha during first and second years, respectively. Similar trend was observed for net benefits and on mean data basis treatment line sowing of wheat+broad casting of lentil recorded highest values of net returns (Rs.55675=00) and B:C ratio (2.65). Hence, for getting higher and economic wheat productivity, broad casting of lentil can be done in line sowing of wheat and can be recommended to farmers practice in Central India.Keywords

An experiment was undertaken to assess the genetic divergence, correlation co-efficient and path analysis among various horticultural traits in thirty-two genotypes of garden pea based on seventeen traits. The present investigation was revealed that all the pea germplasms significantly different for the traits phenotypic and genotypic correlation co-efficients among different characters showed that pod yield per plant had a positive and significant association with the number of branch per plant, number of pod per plant, number of cluster per plant. The path co-efficient analysis revealed that out of all traits studied, pod yield per plant had the maximum positive direct effect on the number of pods per plant followed by internode length, number of seeds per pod and number of branch per plant. All the genotypes were grouped into 5 clusters. The maximum number of genotypes was arranged in cluster-IV (10) and the other four clusters contained 22 genotypes each. Whereas highest inter-cluster distance was recorded between cluster V and II and lowest was observed between cluster IV and III. This result showed that it has the good thought of crossing between two different clusters which having high inter-cluster distance.Keywords
