The group Phureja (Solanum tuberosum L.) has been little studied in Peru, despite its culinary, nutritional and industrial quality and the risk of erosion to which it is subjected in recent decades. The objective of this research was to evaluate the total and commercial yield of tubers of fifteen potato cultivars (Solanum tuberosum, Phureja group). Traditional, yellow, and early cultivars were evaluated from Cajamarca region, Peru, to identify the most productive cultivars within the study group. The work was carried out on a plot of the Silvoagricultural Service of the Universidad Nacional de Cajamarca: 7 ° 10`LS and 78 ° 30’ LW, 2670 masl, 14.7 °C average annual temperature, 64.5% relative humidity and 651 mm of annual precipitation. Seeding was carried out at 0.90 m and 0.40 m between rows and between plants, respectively; in completely randomized block design, with three repetitions. Plant height, number of stems, number and total weight of tubers, number and weight of tubers according to categories, specific gravity, dry matter of tubers and foliage, and harvest index were evaluated. Significant statistical differences were found between cultivars for a total number of tubers, number of commercial tubers, a weight of commercial tubers, plant height, number of stems, dry matter of the tubers and harvest index. The best cultivars in tuber yield were Blanca amarilla (27.8 t/ha), Limeña huachuma (27.4 t/ha), Llanqueja (25.0 t/ha), Amarilla redonda (23.3 t/ha) and Piña amarilla (21.8 t/ha).

Potato (Solanum tuberosum L.) is one of crops which cultivated by farmers in Central Sulawesi. These potatoes are traditionally cultivated without going through the breeding process, so they have high variations. This study aims to obtain information on genetic diversity, heritability, and correlation between the characterics of potatoes from farmers in Napu who are still cultivating potato crops. Design used in this study was a randomized block design with two replications. The results showed that tuber color and harvest age had a small coefficient of genetic diversity. The heritability values ​​of tuber color are include in the small category, Diameter of stem, number of leaves, leaf length, leaf width, leaf color, tuber length, tuber diameter, tuber weight, number of tuber and harvest age in this study are include in the high category. So that, these characteristics can be derived and selection can be made. In Napu potatoes, the number of tubers was genetically positively (medium) correlated between plant height and stem diameters, plant height with leaf width, leaf length with leaf width, leaf length with tuber diameters and tuber diameters with the number of tubers. While the positive correlation was very significant (strong) between plant height and leaf length, and very significant (strong) negative correlation between leaf color and tuber length, so can be used as a selection criteria for increasing potato crops.

The reduction in herbicide use is one of the greatest interests for modern agriculture and several alternatives are being investigated with this objective, including the adoption of cultivars that suppress weeds. The objective of this study was to verify if maize cultivars develop differently, in competition with weeds, to produce green ears and grain. Randomized complete block design was used, with split-plots and five replications. Cultivars DKB 390, DKB 466, DKB 350, AG 7000, AG 7575 and Master, were evaluated in the plots, without weeding and two weedings (at 22 and 41 days after sowing) in sub plots. Twenty-one species were identified in the experimental area, the most frequent being Gramineae (Poaceae), Euphorbiaceae, Leguminosae (Fabaceae) and Convolvulaceae species. There was no difference in the dry biomass above-ground part of the weeds in the plots of the evaluated cultivars. The cultivars behaved similarly in treatments with or without hoeing, except for plant height and ear height evaluations. Without hoeing, plant height increased in cultivar DKB 390, while plant height and ear height decreased in cultivar AG 7575. In the other cultivars, these traits did not change under weed control. The presence of weeds decreased the values of all traits employed to assess green corn yield, with the exception of the total number of green ears and grain yield.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

This trial aimed to evaluate the effect of sequential applications of different plant regulators over growth and flower rachis emission of 'Meyer' zoysiagrass (Zoysia japonica). The study was conducted on 15-month old green turfgrass under a randomized complete block design with four replications. The following plant regulator and doses were tested: trinexapac-ethyl (113+113, 226+113, 226+226, 452+113, 452+226, 452+452, 678+339 e 904+452 g a.i./ha-1), prohexadione-calcium (100+100 e 200+200 g a.i. ha-1) and bispyribac-sodium (40+40 e 60+60 g a.i. ha-1), as well as an untreated control. The turfgrass was mowed again at 3.0 cm aboveground and the second plant regulator was applied when 'Meyer' zoysiagrass was between 5.0 and 6.0 cm high. The effect of the treatments was visually rated for visual injury, plant height, height and number of flower rachis, and total dry mass production of clippings. Only bispyribac-sodium had visual symptoms of injury on 'Meyer' zoysiagrass, and no intoxication was observed at 28 days after the second application (DAAB). The sequential applications of trinexapac-ethyl, prohexadione-calcium and bispyribac-sodium reduced by more than 80% the total clipping dry mass produced by 'Meyer' zoysiagrass. All the plant regulators tested also showed promising results in reducing the height and emission of rachis, especially when trinexapac-ethyl was applied at the doses 452+452, 678+339 and 904+452 g a.i. ha-1. 'Meyer' zoysiagrass turfgrass can be handled with the sequential application of a plant regulator, which reduces the need for mowing over a period up to 110 days after the application of the second plant regulator, and it also avoids deleterious visual effects over turfgrass.
