Utilization of Bumblebee in Crop Pollination
No full textBumblebees play a vital role in pollination of plants due to their large size and hairiness hence are ideal for picking up and transferring pollen. They can vibrate (‘buzz’) flowers and have no communication system but can work efficiently in tunnels as they have a better sense of direction. They are 400 times more efficient than honeybees at any pollination chore and are capable of visiting 30 to 50 flowers per minute. They are non-swarming and less aggressive than honeybees. Bumblebee generally forages during the early morning (0530-0800h) and evening (1700-1900h) time. Bumblebees are better pollinators than honeybees in greenhouses and glass houses and they have a great potential to serve as supplemental pollinators in the cultivation of crops such as tomato, eggplant, cucumber, melon, strawberry, pumpkin, cherry, sweet pepper, etc. It improves the yield and quality parameters of the fruits. In India, efforts are being made at Solan to mass rear bumble bees and utilize them in pollination. A few private companies have attempted to introduce newer species of bumblebees in India. In the present era, the global population of bumblebees is declining due to injudicious use of pesticides, loss of natural colony and mechanization in agriculture and climatic effect
Co-integration and Causality Analysis of “Castor” (Ricinus communis Oil) Markets in India
No full textCastor (Ricinus communis L.) is a major industrial oilseed crop. Because of its numerous uses in the manufacturing of a wide range of industrial uses, castor oil has risen significantly in importance in the global economy. The study examined market integration in major Castor markets in India, including Dhanera, Patan, Kurnool, and Yemmiganur. The co-integration analysis conducted revealed a high level of market integration, as evidenced by the significant positive and negative values of weekly Castor prices across all markets. Unit root tests indicated that the markets were non-stationary, but became stationary when analyzed at the first difference. Further analysis using Johansen\u27s tests identified three cointegrating equations among the markets. The results of the Vector Error Correction Model (VECM) demonstrated long-term price influences between markets. Specifically, Dhanera was found to be influenced by its own price, as well as by prices in Patan and Yemmiganur. Patan, on the other hand, was influenced by its own price, as well as by prices in Dhanera and Yemmiganur. Additionally, Kurnool and Yemmiganur were influenced by prices in neighboring markets
Assessment of Botanicals against the Fruit Borer (Helicoverpa armigera) on Tomato
No full textThe experiment was conducted under the central farm of Sher-e-Bangla Agricultural University, Dhaka in order to assess the efficacy of six promising botanicals (of 50gm/L) against tomato fruit borer (Helicoverpa armigera). The botanicals assessed weree neem leaf extract, Datura seed extract, Garlic bulb extract, Mahogany seed extract, Black pepper seed extract and Allamanda leaf extract. The lowest number of infested fruits in early, mid and late fruiting stages (2.67, 5.63 and 4.48 fruits plot-1 respectively) were obtained from the plots that were treated with neem leaf extract. The highest number of infested fruits were from control plots with 11.33, 16.28, and 13.55fruits/plot obtained at early, mid and late fruiting stage respectively. Similarly, the highest yields of 2.45 kg/plot, 3.10 kg/plot and 2.91 kg/plot at early, mid and late fruiting stages respectively were obtained from the plots treated with neem leaf extract. Increses of weight over control were 75%, 55.78% and 88.96% at early, mid and late harvest respectively. Based on total yield obtained from three harvest (8.54kg/plot) compared to yield of control (5.03kg/plot) and lower toxicity to the environment as well as human being, neem leaf extract was the most promising botanicals for the effective management of tomato fruit borer
