Title: Growth, yield and economics of rain fed chickpea (Cicer arietinum L.) as influenced by integrated weed management Authors: Kaushik, S S; Rai, Anil Kumar; Sirothia, Pawan; Sharma, Ashok Kumar; Shukla, A K Abstract: An experiment was conducted at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna, Madhya Pradesh in Rabi season of the years 2009-10. The experiment containing 12 treatments mechanical i.e. hand weeding at 25 and 50 DAS (Days After Sowing) and chemical i.e. pre emergence application of Alachlor @ 2 kg a.i./ha, Pendimethalin @ 1 kg a.i./ha, Oxyfluorfen @ 0.2 kg a.i./ha, and post emergence application of Imazethapyr @ 100 g a.i./ha at 30 DAS and in combination with Alachlor @ 1.5 kg a.i./ha as Pre-E + 1 HW 25 DAS, Pendimethalin @ 0.75 kg a.i./ha /ha Pre-E + 1 HW 25 DAS, Oxyfluorfen @ 0.15 kg a.i./ha Pre-E + 1 HW 25 DAS, Imazethapyr @ 75 g a.i./ha Post-E 30 DAS + 1 HW 50 DAS. These treatments were laid out in randomized block design. Growth parameters were recorded at successive crop growth stages, yield and yield contributing character recorded at maturity and economics of study was done after harvest. The weed population at 60 DAS was found to be minimum in Pendimethalin @ 0.75 kg/ha + 1 hand weeding at 25 DAS treatment and this treatments has been found suitable for higher seed production and economically viable in rain fed chickpea.

Title: Evaluation of antimicrobial activity of chemical constituents of Achyranthes aspera L. roots against human pathogens Authors: Owk, Aniel Kumar; Mortha, Krishna Rao; Lagudu, Mutyala Naidu Abstract: Antimicrobial activity of roots of Achyranthes aspera L. (Family-Amaranthaceae) was studied against seven pathogenic bacterial and three fungal strains by agar well diffusion method. Antimicrobial activity was recorded for hexane, chloroform, methanol, ethanol and aqueous extracts. Alcohol (ethanol and methanol) extracts exhibited higher degree of antimicrobial activity compared to aqueous, chloroform and hexane extracts. Klebsiella pneumoniae turned out to be the most susceptible bacterium to the crude chemical constituents of roots using the standard drugs, Tetracycline and Clotrimazole. Minimum inhibition concentration values of chloroform, methanol, ethanol and aqueous extracts were determined by the agar dilution method ranged between 62.5 and 1000 µg. The study suggests that the root extracts possess bioactive compounds with antimicrobial activity against the tested bacteria and fungi revealing a significant scope to develop a novel broad spectrum antimicrobial drug formulation from A. aspera.

Title: Medicinal plants of Koont research farm, Pir Mehr Ali Shah Arid Agriculture University Rawalpindi, Pakistan Authors: Qureshi, Rahmatullah; Khanum, Maliha; Shaheen, Humaira; Munir, Mubashrah Abstract: The present study was aimed to collect information on medicinal plants used by the people of Koont village around University research farm and its surrounding areas located on Chakwal road, Punjab, Pakistan. For this purpose, field trips were arranged and the study area was surveyed during August 2008 to July 2009 to collect traditional use of plants by using open-ended and structured questionnaires. Forty three species belonging to 35 genera and 21 families have been identified which are being used by the natives for treating 27 different ailments. Joint pains and injuries were more prevalent complaints in the area, hence most of the species (9.09 %) were utilized for the same, followed by wounds, fever, toothache, as tonic (6.82 % each), boils, skin diseases, constipation, piles, jaundice and cough (4.55 % each). Leaves were the most commonly utilized part (27.03 %) for preparing indigenous recipes followed by the whole plant (16.22 %), roots, seeds, fruits (10.81 % each) and latex, gums (exudates) (8.11 % each). Fourteen plant species possessed novel use in addition to previous knowledge. Based on this study, phytochemical and pharmacological screening is suggested for the novel use in order to validate their authenticity. Page(s): 273-277

Effect of recycled yeast inoculum on fermentation and quality of red wine produced from Punjab purple (Syn H516) grapes

Title: Effect of recycled yeast inoculum on fermentation and quality of red wine produced from Punjab purple (Syn H516) grapes Authors: Kaur, Maninderjeet; Kocher, G S Abstract: Fresh and recycled yeast (Saccharomyces cerevisiae MTCC 11815) inoculums were compared for fermentation of Punjab purple (Syn H516) grapes juice for preparation of red wine. An inoculum size of 10% of recycled yeast was optimized for an ethanol production of 9.5% (v/v) at a fermentation efficiency of 74.53% with stored juice and the same was consistent for up to two recycling lots. The prepared wine was allowed to sediment for 7 days at 4^oC, siphoned and filtered and then matured for 6 months in amber colored bottles. A significant decrease in ethanol, total phenols and yeast count was observed in wines prepared from both fresh and recycled yeast inoculum during storage. Both the type of wines scored 65.9±8.01 and 63.3±8.52 on sensory analysis for fresh and recycled inoculum, respectively and were significantly better than a commercial red wine. The red wines were also found to be rich in 10 amino acids. Page(s): 268-272
