To date, many developing countries such as Iran have almost completely abandoned the idea of decontaminating oil-polluted soils due to the high costs of conventional (physical/chemical) soil remediation methods. Phytoremediation is an emerging greentechnology that can become a promising solution to the problem of decontaminating hydrocarbon-polluted soils. Screening the capacity of native tolerant plant species to grow on aged, petroleum hydrocarbon-contaminated soils is a key factor for successful phytoremediation. This study investigated the effect of hydrocarbon pollution with an initial concentration of 40 000 ppm on growth characteristics of sorghum (Sorghum bicolor) and common flax (Linum usitatissumum), At the end of the experiment, soil samples in which plant species had grown well were analyzed for total petroleum hydrocarbons (TPHs) removal by GC-FID. Common flax was used for the first time in the history of phytoremediation of oil-contaminated soil. Both species showed promising remediation efficiency in highly contaminated soil; however, petroleum hydrocarbon contamination reduced the growth of the surveyed plants significantly. Sorghum and common flax reduced TPHs concentration by 9500 and 18500 mg kg (1), respectively, compared with the control treatment.

A study was conducted during 2004-06 on intercropping under and conditions of Bikaner in newly established 'NA7' aonla (Emblica officinals Gaertn). Mothbean (Vigna acontifolia (Jacq.) Marechal) grown during rainy (kharif) season was a common crop in rotation with winter (rabi) crops, i e fenugreek (Trigonella foenum-graceum Linn.), chickpea (Cicer arietinum L.), mustard [Brassica juncea (L) Czernj. & Cosson] and cumin (Cuminum cyminum L). Growth parameters in terms of plant height, stem girth, canopy spread and canopy volume of aonla was recorded to be significantly more with intercrops compared with its sole plantation. Higher grain and straw yield were recorded in mothbean-chickpea (497, 1250 kg/ha) and mothbean-fenugreek (465, 1 161 kg/ha) crop sequence. Amongst the winter (rabi) crops, grain yield of fenugreek, chickpea, mustard and cumin were higher by 28.05, 38.11, 19.96 and 36.50%, respectively, when grown in association with aonla compared to its sole crops. The highest net profit (Rs 28 260/ha) was obtained from mothbean-cumin cropping system, followed by mothbean-chickpea (Rs 25 024/ha) cropping system. Mothbean-chickpea intercropping with aonla supplemented 22.01, 5.00 and 27.90 kg/ha nitrogen, phosphorus and potassium through crop residues, followed by mothbean- fenugreek crop sequence.

The study was conducted to evaluate the effects of trivalent chromium from different sources on growth, carcass composition, and serum parameters in finishing pigs. Ninety-six crossbred pigs with an initial average body weight of 65.57 +/- 1.05 kg were blocked by body weight and randomly assigned to four treatments with three replicates. Pigs were offered one of four diets including a control diet or the control diet supplemented with 200 mu g/kg chromium from either chromium chloride (CrCl3), chromium picolinate (CrPic) or chromium nanocomposite (CrNano) for 40 days. After completion of the feeding trial, eight pigs from each treatment were selected to collect blood samples, and slaughtered to measure carcass composition. The results showed that supplemental chromium had no significant effect on growth performance, while CrNano increased carcass lean proportion and loin Longissimus muscle area (p<0.05), and decreased carcass fat proportion and 10(th) rib backfat depth (p<0.05). CrPic supplementation also resulted in lower fat proportion and larger Longissimus muscle area (p<0.05). The addition of Cr from CrNano or CrPic decreased serum glucose (p<0.05) and increased concentrations of total protein and free fat acid in serum (p<0.05). Serum urea nitrogen. triglyceride and cholesterol were decreased (p<0.05),. and serum high density lipoprotein and lipase activity were increased (p<0.05) with the supplementation of CrNano. Serum insulin was decreased (p<0.05) by supplemental Cr from CrNano or CrPic, and serum insulin-like growth factor I was increased significantly in the CrNano treated group. These results suggest that chromium nanocomposite has higher efficacy on carcass composition in pigs compared to the traditional chromium sources.

Investigations were carried out at the Agricultural Research Farm of the Arunachal University of Studies, Namsai, Arunachal Pradesh, during Kharif season 2018-19 to identify the promising rice variety suited to the agro climatic conditions of Namsai.Two improved rice varieties (MTU-1010, MTU-7029), two local cultivars (Sali, KhamtiLahi) and an introduced rice variety (Thailand Lahi) were evaluated in randomized block design with five replications. The varieties differed significandy for growth and yield parameters. The tallest variety was Thailand Lahi (164.08 cm) followed by KhamtiLahi (147.34 cm), whereas the maximum number of productive tillers was observed in MTU-7029 (13.84) and MTU-1010 (13.10) followed by Thailand Lahi (11.84). Thailand Lahitook minimum (7.2) days for panicle emergence whereas, Sali took maximum (14.4) days. The varieties MTU-7029 and MTU-1010 had the shortest crop duration(126 days). Khamti Lahi had the longest (155 days) duration. The highest number of grains per paniclewas observed in Khamti Lahi (232.4) followed by Thailand Lahi (209.6) and the lowest was found in MTU-1010 (121.4). The panicle length was the highest in Thailand Lahi (25.8 cm) and Sali (25.4 cm). Whereas, MTU-1010 had the lowest panicle length (22.1 cm). Average length of grains was maximum in Thailand Lahi (0.96 mm) and minimum in Sali (0.68 mm). The highest 1000 grain weight (29.08 g) was observed in variety Thailand Lahi and the lowest was found in KhamtiLahi (21.60 g). The maximum yield per plotwas obtained from the variety Thailand Lahi (4.72 t/ha). This was followed by the local varieties Sali and KhamtiLahi (3.86 and 3.38 t/ ha), which were on par with each other.

The experiment was carried out in the Seed Laboratory of Bangladesh Agricultural Development Corporation (BADC), Gazipur during June to July 2014 to investigate the effects of different priming methods on seed germination and the seedling growth of some rice (Oryza sativa L.) ?varieties. Four rice varieties: 1) Nerica, 2) BRRI dhan51, 3) BRRI dhan41 and 4) BRRI dhan49; and six priming treatments: 1) On-farm Priming, 2) Hardening, 3) Hydro-priming, 4) Osmo-hardening, 5) Vitamin C Priming and 6) Control were used in the experiment. The experiment was laid out in a completely randomized design (CRD). The treatments were replicated three times. The germination percentage and seedling growth parameters differed significantly among the priming treatments. For germination, Nerica variety showed poor performance, whereas the other varieties were found superior. Among the priming treatments, Vitamin C priming and Osmo-hardening were found superior. In case of interaction, germination was increased with Vitamin C priming and Osmo-hardening in Nerica. For seedling growth parameters, particularly vigor index, shoot and root lengths, BRRI dhan41 and BRRI dhan51 were found superior. The priming treatment Vitamin C and Osmo-hardening performed better than others.? Seedling vigor index was increased with Vitamin C priming and Osmo-hardening in Nerica variety. Shoot length at 15th day was influenced by hydro-priming in Nerica. Root length at 10th day was significantly increased with hardening in BRRI dhan41. Vitamin C priming and Osmo-hardening could therefore, be used for improving germination and seedling growth of Nerica.

A field experiment was conducted at Birsa Agricultural University, Kanke, Ranchi, during the year 2016-17 to study the effect of herbicides on growth, yield and quality of onion. The treatments comprised of application of oxyfluorfen (0.25 kg/ha) oneweek before transplanting, oxyfluorfen (0.25 kg/ha) immediately after transplanting, pendimethalin (1.00 kg/ha) one week before transplanting, pendimethalin (1.00 kg/ha) immediately after transplanting, pretilachlor (0.75 kg/ha) one week before transplanting, pretilachlor (0.75 kg/ha) immediately after transplanting, quizolofop-ethyl (1.00 kg/ha) 20 days after transplanting (DAT), hand weeding (HW) and weedy check. Results revealed that highest plant height (66.67 cm), number of leaves (5.98) and neck thickness (4.76 cm) were recorded in hand weeding at all the growth stages, which was at par with pendimethalin immediately after transplanting and pendimethalin one week before transplanting.The increase due to HW was in the tune of 78.88, 55.73 and 59.20% respectively than weedy check whereas, pendimethalin immediately after transplanting of onion recorded 63.94, 52.56 and 51.84% increase over weedy check. Hand weeding recorded 122% more yield (23.71 t/ ha) than weedy check (10.68 t/ha). Juice contentand TSS was the highest in hand weeding which was at par with pendimethalin immediately after transplanting, application of pendimethalin one week before transplanting and oxyfluorfen immediately after transplanting.

Growth and ethanol production by three strains (MSN77, thermotolerant, SBE15, osmotolerant and wild type ZM4) of the bacterium Zymomonas mobilis were tested in a rich medium containing the hexose fraction from a cellulose hydrolysate (Aspen wood). The variations of yield and kinetic parameters with fermentation time revealed an inhibition of growth by the ethanol produced. This inhibition may result from the increase in medium osmolality due to ethanol formation from glucose. [References: 26]
