Banana (Musa spp.) production in Jalgaon is confined to the 'Cavendish' cultivar. The introduction of a range of high yielding and disease resistant cooking and dessert cultivars in Jalgaon could play a potential role in raising incomes of millions of small scale farmers. At the research farm of Jain Irrigation Systems Ltd., the trials were established. The objectives of this study were (i) to evaluate the general performance of the different cultivars grown in south India and the hybrids and (ii) to analyze acceptability of the cultivars. The FHIA (Fundacion Hondurena de Investigacion Agricola) hybrids performed relatively well as compared to the 'Cavendish' and other south Indian group of cultivars. Although 'FHIA 23' was the most vigorous, this cultivar took the longest time to produce a bunch. The selection, 'Mahalaxmi' produced the large bunch but it was still lower than that of 'Grande naine' the local check used in the trials. The 'Grande naine' emerged as the best cultivars in terms of postharvest quality and acceptability. In spite of better yields of 'FHIA 23', the hybrid could not pass through acceptability test. Less than 30% of the participants indicated their preference for 'FHIA 01', or 'FHIA23'. © ISHS 2013. Source

Agricultural lands in the peri-urban area of New Delhi have been irrigated with treated wastewater from the Keshopur Effluent Irrigation Scheme (KEIS) since 1979. An attempt has been made to study the influence of wastewater irrigation on pH, electrical conductivity, organic carbon, and dynamics of heavy metal concentrations in vadose zone under KEIS. For this study, agricultural lands which have been receiving the sewage irrigation for 20, 10, and 5 years were selected. Adjacent tube well water-irrigated fields were selected and used as reference. Results indicate that there was a significant decrease in soil pH and electrical conductivity (EC) of sewage water-irrigated fields as compared to tube well water-irrigated fields. Organic carbon (OC) content in 20 years sewage-irrigated soil (0–15 cm) increased by 244 % over tube well water-irrigated soil. The increases in organic carbon content for 10 and 5 years sewage-irrigated surface soil (0–15 cm) were 138 and 60 % over tube well water-irrigated soils. The second-order polynomial model suggested that there is a possibility of accumulation of organic carbon in soil due to sewage irrigation at 1.55 t−1 ha−1 year. There was an increase in diethylene triamine pentaacetic acid (DTPA)-extractable Zn content in 20, 10, and 5 years sewage-irrigated soils (0–15 cm) to the extent of 86, 38, and 36 % over tube well water-irrigated soils, respectively, while only 20 years sewage-irrigated soils showed a significant increase in DTPA-extractable Cu (289 %) in surface layer (0–15 cm) over tube well-irrigated soils. In case of Fe, 127, 88, and 76.6 % increases in available Fe content (DTPA-Fe) were recorded under 20, 10, and 5 years sewage-irrigated soils, respectively, over controls. Like Cu, DTPA-extractable Ni also exhibited a significant increase (42.2 %) in 20 years sewage-irrigated soil over tube well-irrigated ones. It appears that due to sewage irrigation particularly in surface soil, DTPA-Mn content either remained same or showed a slight decline as compared to tube well-irrigated soils. The assessment of contamination factor (CF) in respect of total metal content in soil indicated the moderate level of metal contamination even after such long-term of sewage irrigation. © 2015, Springer International Publishing Switzerland.

Rural India derives its energy needs for cooking and heating through the use of fuel wood and for lighting and agricultural operations through kerosene and diesel. Use of fuel wood has aggravated the problem of de-forestation, while availability of kerosene and diesel cannot be guaranteed due to corrupt practices in the public distribution systems. In contrast, urban India derives its energy needs through LPG cylinders, petrol, and electricity. However, their cost and uncertainty rendered them beyond the reach of lower income population. This scenario is more or less true with many developing countries. To meet these objectives, biogas generation from biodegradable waste using anaerobic digestion (AD) appears to be a sustainable avenue as it could be used for (a) water and space heating of farmhouses, animal shelters, (b) generating steam for food processing plants, and (c) electricity generation, in addition to reducing the pollution/hazard potential of these wastes. Many of the underdeveloped and developing countries are in the temperate zone and thus mesophilic AD could provide a desired pathway to achieve a long delayed need of energy for comfortable living, farming, and industrial operations. Efforts made in this direction are reviewed in the present article. © 2010 Informa Healthcare USA, Inc. Source

The present invention proposes a device for controlling discharge by a conduit. The device comprises a body, a mouth or a first portion attached to the body and a needle or a second portion attached to the body. The mouth and the needle are coaxial. The mouth receives an end portion of the conduit, such that when A received, an internal surface of the mouth is in contact with an external portion of the end portion of the conduit. The needle is arranged to be inserted into the received end portion of the conduit, such that an external surface of the needle is in contact with an internal surface of the end portion of the conduit.
