To obtain high yields in the soybean crop, it is necessary to have the minimum of competition among the plants.The objective of this work was to evaluate the influence of different spacing on productivity components and soybean yield. The design adopted was randomized blocks with 4 treatments (22, 44, 66 and 88 cm between rows) and six replicates. The cultivar used was 5909 with a population of 204 thousand plants per hectare. The response variables evaluated were plant height and first pod insertion, stem diameter, number of pods per plant, number of grains per pod, mass of one thousand grains and productivity. The height of plants and the diameter of the stem behaved in a quadratic manner, where the measure with which one increased the other reduced. The highest number of pods per plant (92) was obtained with the spacing of 64 cm between rows. The number of grainsper pod reduced linearly with increasing row spacing. The mass of 1000 grains and the productivity presented a quadratic behavior for the spacing, where the highest productivity 4772.60 kg ha-1was obtained with the spacing of 60 cm. The stem diameter showed a positive correlation with the number of pods per plant and with productivity. The height of insertion of the first pod showed a positive correlation with the mass of a thousand grains. The number of pods per plant was the variable that presented the highest correlation with productivity (0.84).

Balance® (75% a.i. isoxaflutole) at 100 g/ha is registered in Australia for the control of several broadleaf weeds in chickpea. Polyhouse and field experiments were carried out to examine the tolerance of chickpea genotypes to isoxaflutole. Seven rates of isoxaflutole [0, 18.75, 37.5, 75 (recommended rate), 150, 300 and 600 g a.i./ha] were applied to 20 genotypes in the first polyhouse experiment while in the second experiment, 16 genotypes were tested. In the field, six genotypes were treated with five herbicide rates (0, 37.5, 75, 150 and 300 g a.i./ha). There was a strong dose response in the polyhouse experiments in visual injury ratings, plant height, and shoot and root dry weight. In general, there was less herbicide injury to the kabuli genotypes than in the desi chickpea genotypes. Chickpea genotypes Yorker, Howzat, Amethyst, Gully, 91025-3021, Jimbour, S 95425 and FLIP 94-92C exhibited higher overall mean injury rating in experiment 1. Among these genotypes, shoot dry matter was reduced significantly in Amethyst, Jimbour, 91025-3021 and S 95425. Root dry matter in Amethyst, Jimbour, Yorker, 91025-3021 and S 95425 was also reduced significantly. Height was reduced significantly in all of the above eight genotypes. Although there was less overall injury level in the second polyhouse experiment, which was at lower temperatures, Howzat, Yorker, 91025-3021, FLIP 94-92C and S 95425 again recorded high overall mean injury ratings and should be regarded as more susceptible to isoxaflutole than the other strains. In comparison, 97039-1275 and Kyabra recorded very minor injury symptoms in all the experiments and can be regarded as the most tolerant. The herbicide injury to the genotypes in the field was less than in the polyhouse although Yorker and 91025-3021 showed injury symptoms at early stages of growth. The injury symptoms were temporary and did not produce significant effects on the overall crop growth and yield. It is suggested that plant breeding programs take into account the relative susceptibility of new chickpea genotypes to isoxaflutole.

[PERFORMANCES OF TEN SOYBEAN VARIETIES AS INTERCROPPED WITH SUGARCANE]. An intercropping system between soybean and sugarcane may be an alternative to increase soybean production in Indonesia, but not all soybean varieties are suitable for intercropping system as different soybean varieties may perform differently under intercropping system and monoculture system. Therefore, suitable soybean varieties for intercropping should be identified to warrant the higher crop productivity. This study was conducted to to compare the growth and yield performances of ten soybean varieties in monoculture and soybean-sugarcane intercropping systems. The experiment was laid in a Split Plot Design with three replications. The cropping systems (monoculture and intercrop) were allotted in the main plots, while the soybean varieties (Gepak Kuning, Kaba, Wilis, Tanggamus, Burarang, Sinabung, Anjasmoro, Agromulyo, Ring-1, and Gema) were assigned as the sub plots and allotted randomly in each main plot. On overall, the intercropping system had significantly reduced the soybean pod number, seed number, wight of 100 seed, and, seed yield/plant, but increased plant height as compared to the monoculture system. The exceptions were observed for seed number and weight of 100 seed. The reduction of seed number was not significant on Agromulyo and Dering-1.On the other hand, Anjasmoro and Dering-1were the only varieties showed significant reduction in weight of 100 seed. Kaba, Willis, Tanggamus, Burarang, Sinabung, and Dering-1 showed their consistant performormances across the cropping systems. However, the higher seed yield/plant in both systems was observed on Gepak Kuning, Willis, Burarang, Agromulyo, Dering-1, and Gema.

AbstractThe objective of the presented study was to look at the effect of Pratylenchus coffeae and Meloidogyne spp., the two major nematode species associated with banana ( Musa spp.) in North Vietnam, on the plant growth and yield of cv. Grand Naine (AAA) and four local banana cultivars, Ngu Tien (AA), Hot (BB), Ben Tre (AAA) and Tay Tia (ABB). Inoculated plants were compared with nematode-free control plants in terms of plant growth, crop cycle duration and yield under field conditions in Hanoi, North Vietnam. Infection with P. coffeae did not affect the crop cycle duration or the plant height, the pseudostem girth or the number of standing leaves at harvest of any of the cultivars, but did significantly reduce the bunch weight of cv. Ngu Tien from 6.6 to 5.3 kg (20% reduction), the bunch weight of cv. Tay Tia from 7.3 to 5.9 kg (19% reduction) and the bunch weight of cv. Grand Naine from 6.9 to 6.0 kg (13% reduction). The bunch weight of cvs Hot and Ben Tre was not significantly affected. The number of hands of the inoculated and the control plants did not differ for any of the cultivars but infection with P. coffeae resulted in a 34% reduction in the number of fingers of cv. Grand Naine (from 67 to 44 fingers). The number of fingers of the other cultivars were not affected by inoculation with P. coffeae. Infection with Meloidogyne spp. did not affect the time from planting to harvest for any of the cultivars, but the time from planting to shooting was increased from 367 to 387 days for cv. Ngu Tien. The plant height and the pseudostem girth at harvest of cv. Grand Naine were significantly reduced by 27% and 18%, respectively. The number of standing leaves as well as the plant height and the pseudostem girth at harvest of the other cultivars were unaffected. Infection with Meloidogyne spp. significantly reduced the bunch weight of cv. Ngu Tien from 6.6 to 5.1 kg (23% reduction) and the bunch weight of cv. Grand Naine from 6.9 to 5.6 kg (19% reduction). The bunch weight of cv. Hot was unaffected. Infection with Meloidogyne spp. reduced the number of hands of cv. Ngu Tien by 14% (from 6.2 to 5.4 hands) the number of fingers of cv. Grand Naine by 25% (from 67 to 50 fingers). The number of hands and fingers of the other cultivars were not affected. The results indicate that in areas where the burrowing nematode, Radopholus similis, is not present, other nematodes, especially Meloidogyne spp., may become more important in terms of damage and yield loss.

Between 1995 and 2008 the granting of the Binding Forest Award led to fresh cooperation between forest owners and research on silviculture, growth and yield at the Swiss Federal Institute for Forest, Snow and Landscape Research. Various topics were treated: a study of the beech coppices in Rothenfluh rapidly made it clear that very little was known about this formerly widespread type of forest management and its consequences. The same was true to a lesser extent for the conversion of rather uniform high forest into selection forest (in Plasselb), and for the selective management of light demanding tree species, such as the oak, in Rheinau. In Boudry, cooperation between practice and research already existed: the prize award here led to new approaches in the production of high quality oak, whilst taking ecological values into account. All these new projects are still in their earliest stages and will call for a great deal of “sustainability”, in both senses of the word, from all those involved. Considering the long periods of time required for the development of forest ecosystems, this is in fact self-evident.

The study aimed to determine the effect of the combination of city waste compost and cattle manure on the growth and yield of pakcoy plants (Brassica rapa, L. Chinensis) in Aluvial, Indramayu Regency. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Wiralodra University, Indramayu Regency from March to August 2018. This study used Factorial Pattern Randomized Block Design with two factors. The first factor is city waste compost and the second factor is cattle manure with 4 levels: 0%, 3.0%, 6.0%, and 9.0%, repeated twice. The results showed that there was an independent influence between city waste compost and cattle manure on plant height and number of leaves. The best combination to increase the feasibility weight of pakcoy consumption is by giving city waste compost 9.0% (S4) and cattle manure 6.0% (K3).

A pots experiment was conducted at the Department of Biology/College of Education for Girls/University of Anbar during Autumn season of 2018-2019 to study the effect of the salinity irrigation water and spray by humic acid in some of morphological, physiological, growth and yield traits of wheat cv. IPa. The experiment was randomized complete block design (RCBD) with three replications. The first factor was assigned for irrigation by saline water at four level (S0, S1, S2 and S3), while the second factor was the foliar spraying of humic acid in three level (0.0, 1.0 and 1.5 g l-1). The results showed that there was significant reduction in plant height, vegetative dry weight, biological yield and chlorophyll leaves content when the plants were irrigated by saline water approached to 41.09 cm, 0.747 g, 0.849 g plant-1 and 38.67 SPAD, respectively at salinity level of 8.3 ds m-1 compared with the plants which irrigated by fresh water. The total carbohydrates were significantly decreased at the treatment of 8.3 ds m-1 reached 18.71 mg g-1. Spray levels humic acid achieved a significant increase in plant height, dry weight of the vegetative part, biological yield and chlorophyll leaves content sprayed at 1.0 and 1.5 g l-1 compared to no sprayed. Nitrogen concentration was significantly increased, while both phosphorus and potassium were decreased in the vegetative parts of wheat as the salinity of irrigation water increased. However, the increase of humic acid levels led to significant increasing in nitrogen, phosphorus and potassium concentration.

Bryophytes are the second largest group of land plants and are also known as the amphibians of the plant kingdom. 67 species of bryophytes have been reported from select locations across the state of Gujrat. The status of family fissidentaceae which is a large moss family is being presented in this paper. Globally the family consists of 10 genera but only one genus, Fissidens Hedw. has been collected from Gujarat. Fissidens is characterized by a unique leaf structure and shows the presence of three distinct lamina, the dorsal, the ventral and the vaginant lamina. A total of 8 species of Fissidens have been reported from the state based on vegetative characters as no sporophyte stages were collected earlier. Species reported from the neighboring states also showed the absence of sporophytes. The identification of different species was difficult due to substantial overlap in vegetative characters. Hence a detailed study on the diversity of members of Fissidentaceae in Gujarat was carried out between November 2013 and February 2015. In present study 8 distinct species of Fissidens have been collected from different parts of the state. Three species Fissidens splachnobryoides Broth., Fissidens zollingerii Mont. and Fissidens curvato-involutus Dixon. have been identified while the other five are still to be identified. Fissidens zollingerii Mont. and Fissidens xiphoides M. Fleisch., which have been reported as distinct species are actually synonyms according to TROPICOS database. The presence of sexual reproductive structures and sporophytes for several Fissidens species are also being reported for the first time from the state.
