Systematic surveys of root-knot nematodes were conducted in three states (Jos, Kaduna and Katsina) of Northern Nigeria. Infected root samples of vegetables were collected in polythene bags and brought to the laboratory. Root galls were dissected for mature females and perineal patterns were prepared from each sample. Species of root-knot nematodes were identified on the basis of perineal patterns. Two species Meloidogyne incognita and M. javanica were found to be associated with vegetables crops. M. incognita was present on all the vegetables, while M. javanica was present on few vegetables. Frequency of M. incognita was greater than M. javanica. Overall, incidence of disease was found 49.3% and intensity (gall index/egg mass index) was ranged from 2–4/0–4 with variation on different vegetables.

Laboratory, pot and field experiments were conducted to find out the responses of two wheat cultivars: MP4010 [V1] and Sujata [V2] at different growth stages under water stress with varying potassium doses, namely 20kg/ha [K1], 40kg/ha [K2] and 60kg/ha [K3]. Water stress was imposed by withholding water at different stages, that is, I0 [rainfed], I2[vegetative stage] and I3[before flowering stage] wherein I1served as normal irrigation. In laboratory experiments polyethylene glycol ‘6000’ [15%] was employed as stress treatment. Potassium treatments resulted in an increase in total chlorophylls, carotenoids and yield parameters in both the cultivars. Relative water content [RWC] improved with increasing potassium doses under all the irrigation schedules. Free proline contents were greater in plants grown under rainfed conditions in comparison to normal irrigation and in potassium treatments.

An investigation was conducted to find out the effect of GA3 and salicylic acid on biochemical parameters and yield attributes of black gram (Vigna mungo L.) cv. Narendra Urd-1. The crop was grown under field condition, and GA3 concentrations 50, 100 and 150 ppm and salicylic acid concentrations 100, 125 and 150 ppm were applied as a foliar spray at different growth stages. That resulted in the foliar spray of SA 150 ppm at 25, 40 and 55 DAS, and was found most effective to increase the biochemical parameters, namely, total chlorophyll content, nitrate reductase activity, nitrogen content in leaf, protein content in seed and yield attributes viz. number of pod per cluster, number of pod cluster per plant, pod length, number of seeds per pod, number of seeds per plant, seed yield per plant and seed yield quintal per hectare.

Salinity is one of the major environmental determinants of plant growth and productivity. A pot experiment was performed using six cultivars of mungbean [Vigna radiata L.] to evaluate the difference in their response to NaCl toxicity under growth chamber conditions. The pots containing reconstituted soil were supplied with different concentration of salinity [0, 50 and 100 mM NaCl]. Increasing concentration of NaCl in the soil resulted in decreased net photosynthesis, plant dry mass and seed yield. Maximum significant reduction in growth, photosynthesis and yield were observed with 100 mM NaCl in all the cultivars. Our results indicate that the cultivar Punt Mung is found to be more tolerant to salinity stress, recording higher net photosynthesis, plant dry mass and seed yield associated with low Na+ and Cl− content and high osmolyte accumulation in the plant leaves. Cultivar T44 experienced maximum damage in terms of reduction in net photosynthesis, plant dry mass and seed yield and emerged as a sensitive cultivar. The data of tolerance index of Punt Mung were found to be higher among all tested mungbean cultivars which indicate its higher tolerance to salinity. Better coordination of osmolytes and lower values of Na+ and Cl− protected Punt mung from NaCl toxicity, whereas lesser accumulation of osmolytes and higer values of Na+ and Cl− in T44 resulted in maximum damage. Cultivars of mungbean were ranked with respect to their tolerance to salinity: Punt mung > Pusa 9531 > Pusa Baisakhi > Samrat > SML 267> T44, respectively.
盐度是植物生长和生产力的主要环境决定因素之一。以6个绿豆品种(Vigna radiata L.)为试验材料，研究了不同栽培条件下绿豆对NaCl胁迫的反应差异。不同浓度的盐分[0、50和100 mM NaCl]分别供给土壤罐。土壤中NaCl浓度的增加导致净光合作用、植株干质量和种子产量下降。在100 mM NaCl处理下，所有品种的生长、光合作用和产量均显著下降。结果表明，蓬特芒对盐胁迫具有较强的耐受性，具有较高的净光合作用、植株干质量和种子产量，且植株叶片中Na+和Cl−含量较低，渗透物积累较多。品种T44在净光合作用、植株干质量和种子产量方面的损害最大，是一个敏感品种。耐盐指数在所有绿豆品种中较高，说明其耐盐能力较强。较好的渗透产物配位和较低的Na+和Cl -值保护了Punt绿豆免受NaCl毒害，而T44中较少的渗透产物积累和较高的Na+和Cl -值导致最大的伤害。绿豆品种耐盐性排序为:蓬特绿>普沙9531 >普沙白沙> Samrat > SML 267> T44。

The present work deals with the application of Shannon Index to explore the spatial extent and pattern of air pollution around a paper mill. The index measures the change in lichen diversity in response to the polluted environment around a paper mill in Assam, North-East India. The Shannon index around the paper mill ranged from 0.56 at 2.4 km to 1.20 at 13.7 km with a mean value of 0.92. About 47% of the sites have Shannon index value below mean value. The index does not show significant correlation with the distance from the paper mill. The values are plotted with the help of kriging interpolation and an air quality model is prepared. The dark shades in the model indicate highly polluted regions while the brighter shades indicate less polluted to clean areas. Higher polluted areas with low values of Shannon index are the regions around and nearer to the paper mill, town area, and around stone crusher units. It is concluded that the Shannon index is a potential indicator to measure the effect of air pollution and can be used to delineate the pollution zones around any industrial area.

Heavy-metal stress is one of the major stresses affecting plant growth and productivity globally. In order to improve the yields of plants, growing under heavy-metal stress became remarkably important for sustainable agriculture. Plants experience oxidative stress upon exposure to heavy metals that lead to cellular damage. In addition, plants accumulate metal ions that disturb cellular ionic homeostasis. This experiment was undertaken with an objective to determine how the rate of seed germination, seedling growth and leaf area is influenced by various concentrations of heavy metals, lead and nickel at 10, 50 and 100 μM/L concentration in black gram (Vigna mungo L.) seedlings. These concentrations significantly affect all these parameters. Lower concentration, that is, 10 μM/L of lead and nickel showed less affect than high concentration, that is, 50 and 100 μM/L. Shoot length was more affected than the root length in Vigna mungo seedlings. Nickel showed more toxic effect than lead at all the aforementioned concentrations as compared to control. However, the addition of 5 mM/L nitrogen (ammonium nitrate) to the plants somehow minimised the effect and was beneficial to the plants. This study suggests that cultivation of Vigna mungo in toxic soils having heavy metals should be avoided or appropriate control measures be adopted to maintain the heavy metal content of the soil below the damaged (threshold) level, for this nitrogen may be used as a good detoxifier.

Pigeon pea is a tropical grain legume grown mainly in India. Though largely considered an orphan crop, it has a huge untapped potential for improvement both in quantity and quality of production in India. More than any other legume adapted to the region, pigeon pea uniquely combines optimal nutritional profiles, high tolerance to environmental stress, high biomass productivity and most nutrient and moisture contributions to the soil. Pigeon pea is rich in starch, protein, calcium, manganese, crude fibre, fat, trace elements and minerals. Besides, its high nutritional value, pigeon pea is also used as traditional folk medicine in India, China, Philippines and some other nations.

The potential of nitric oxide (NO) was studied individually or in combination for the alleviation of 100 mM NaCl stress in mustard (Brassica juncea L.). Salinity generally decreased photosynthesis and growth characteristics. The individual application of NO at 50 μM and 100 μM promoted and enhanced the photosynthetic efficiency and growth, but under salinity stress the application of 100 μM NO was proved more efficacious than 50 μM in alleviating salt stress by limiting the accumulation of NaCl content of ions and reducing oxidative stress. However, application of high (150 μM) concentrations of NO showed inhibitory results in the presence of 100 mM NaCl. These results indicated that the application of NO at 100 μM alleviates the salt-induced decrease in photosynthesis mainly through decreasing chlorophyll degradation or by increasing PS II efficiency, rubisco activity and net photosynthesis along with growth.

The ecosystem of Himalayan region have immense mineral wealth. Limestone found in Himachal Pradesh. is an important industrial mineral. Therefore, the present work was undertaken to study the floristic composition at Alsindi Cement mining area in Mandi district of H.P. where Lafarage Cement [Ltd] Company is establishing a Cement factory and further to understand the life form spectrum of different plant species. A total of 76 species [22 trees, 18 shrubs, 4 climbers, 6 herbs, 4 grasses and 3 legumes] were found in this area. It was found that most of the species occurred at the HB [Hill base]. The life form spectrum recorded that 53% were phenerophytes, 18% therophytes and 29% hemigeophytes. When the present spectrum is compared with normal spectrum, it was found that phenerophytes, therophytes and hemigeophytes were more then normal spectrum, whereas geophytes and Chamaephytes were completely absent. A number of studies conducted earlier in different regions also show that it is not only the climate but biotic interference, also changes the life form and floristic composition of the area. Therefore, the primary strategy of the plants is survival by evolving wide range of life form patterns and occupy varied ecological niches in different area.

Post-harvest sugarcane deterioration is significant vicinity for cane growers as well as sugar millers. These deterioration causes low sugar recovery in mills. One of the major parts is played by the microbial infestation after harvest of cane. The most devastating microbe for it is Leuconostoc that causes large amount of post-harvest sucrose losses in cane. These microbes enter through the cut ends by the contact through soil as they are soil-borne or through contaminated cane cutters. They proliferate at a higher rate as soon as it reaches the interior of the cane, where there is ample amount of sucrose that act as a feast for its proliferation, leading to enhancement in post-harvest cane deterioration. This not only creates problems at field level but also during processing in mills as they get washed away from the cane surface and enters into the juice and thus also reduces the sucrose content by producing the enzyme dextrasucrase that converts sucrose into dextran. This dextran formation also causes troubles during milling, like, increases viscosity as well as alters the shape of sugar crystal. Although many measures have been taken for overcoming these losses caused by it; however, still complete eradication is required. This review emphasises on the effect of Leuconostoc over harvested sugarcane as well as its role in post-harvest cane deterioration.
