Maize has great economic prominence in national and international agribusiness, being used for various purposes such as grain use and in the form of bulky (silage). This study aimed to evaluate the agronomic characteristics of twelve maize hybrids for silage production in Inconfidentes-MG. Twelve hybrids were used: 20A78PW, 2B512PW, 2B533PW, 2B688PW, 30F53LEPTERA, AG8740-PRO3, DKB345-PRO3, DKB363-PRO3, LG3055-PRO3, LG6036-PRO3, MAXIMUS-VIP3, and MG652PW. The treatments were implanted in a randomized block design (CBD) containing three repetitions. The experimental plots consisted of four lines of five meters in length and 0.8 m spacing between rows, with the two central lines as useful areas. The parameters evaluated were green matter productivity, dry matter productivity, plant height, ear height, average stalk thickness, cutting window, flowering, and cycle. The hybrids 20A78PW; 2B533PW; DKB345-PRO3, and DKB363-PRO3 presented the highest cut-off window values in relation to the others. LG3055-PRO3 hybrid presented the smallest cut-off window. The hybrids 30F53LEPTERA, AG8740, DKB345-PRO3, LG6036-PRO3, and MG652PW presented the highest plant height values. No statistical difference was observed between the hybrids for the variables: green matter productivity, ear height, and stalk thickness. Hybrids AG8740, DKB345-PRO3, LG6036-PRO3, and MG652PW obtained the highest dry matter productivity values. Hybrids 20A78PW, 2B533PW, DKB345-PRO3, and DKB363-PRO3 presented the lowest male and female flowering time. Hybrid DKB345-PRO3 stood out, showing great potential to be recommended and cultivated by silage producers.

ABSTRACT The objective was to evaluate the effect of different spacings and mineral fertilizations on cactus pear growth and production in a randomized block design, with three replicates, in a 3 x 4 factorial scheme: three spacings, 1.00 x 0.50 m, 2.00 x 0.25 m and 3.00 x 1.00 x 0.25 m, and four fertilizations, 000-000-000, 000-150-000, 200-150-000 and 200-150-100 kg ha-1 of N, P2O5 and K2O, respectively. Plant growth was evaluated between 90 and 390 days and production and growth were evaluated at 620 days after planting. There were significant interactions between spacing and fertilization for plant height, number of cladodes and cladode area index from 90 to 390 days and for production of fresh and dry matter at 620 days after planting. Spacing influenced cladode area index, while fertilization influenced plant height, number of cladodes and cladode area index at 620 days after planting. Plant height showed cubic effect for the days after planting. Number of cladodes and cladode area index were dependent on spacing, fertilization and plant age, and fitted to cubic models. The best results of growth and production of fresh and dry matter are associated with NPK and NP fertilizations and the spacing of 1.00 x 0.50 m.

This study aimed to assess productivity and nutritional value of the tropical grasses Brachiaria brizantha cv. Piatã, Xaraés, and Marandu, Panicum maximum cv. Mombaça, and B. ruziziensis cv. Kennedy in the interseason of an integrated crop-livestock (ICL) system since alternatives are needed for forage production for animal grazing in Autumn and Winter. The experimental design was a randomized block design in a split-split plot scheme with four replications. The treatments of plots consisted of five grasses, subplots consisted of three cropping systems (monoculture, intercropping with corn and unsuppressed grass, and intercropped with corn and suppressed grass), and sub-subplots consisted of four cutting intervals of grasses (50, 90, 125, and 195 days after emergence - DAE). The experiment was carried out from February to September 2014. Dry matter (DM) productivity, obtained at 195 DAE for the three cropping systems (monoculture grass, unsuppressed and suppressed grass in intercropping), were 18.45, 7.15, and 3.05 t ha?1, respectively, and average crude protein contents of leaf blades of grasses decreased linearly between the cutting intervals of 50 to 195 DAE from 19.95 to 9.70%, respectively. Under integrated systems, the studied grasses showed better yields and nutritional quality when compared to traditional grazing systems. Panicum maximum cv. Mombaça and Brachiaria brizantha cv. Xaraés and Piatã had the highest leaf and crude protein yields when compared to Brachiaria ruziziensis cv. Kennedy and Brachiaria brizantha cv. Marandu. In terms of nutritional value, Brachiaria ruziziensis cv. Kennedy was superior to Mombaça and Xaraés grasses but had lower total dry matter yield. Finally, Xaraés, Piatã and Mombaça grasses are recommended choices ICL systems when fodder grass production is the goal.

In the Central Altiplano of Bolivia, the production of forage oats is important for the feeding of herbivorous livestock; however, the yields obtained at the producer level register low averages in dry matter. The objective was to evaluate the agronomic performance of three oat varieties, with levels of ground coca leaf as green manure, at the Kallutaca Experimental Center in the department of La Paz. A randomized block design was applied with a divided plot arrangement with four replications. The factors were oat varieties (Aguila, Gaviota and Texas) and levels of ground coca (0, 30 and 60 t ha-1), with variables days to emergence, number of tillers, plant height and dry matter yield. The results at days to emergence show differences in time 60 and 0 t ha-1 with 14 and 11 days. In relation to the number of tillers per plant, in varieties the behavior is similar with an average of 7 tillers; in relation to interaction, the values show significance. In plant height, the means recorded for the Texas variety were 137.10 cm, in the interaction the values were equal. In dry matter, there were significant differences in 60 and 30 t ha-1 with 16 427.27 and 15 281.82 kgDM ha-1, the Gaviota variety with 14 706.06 kgDM ha-1. The treatments influenced the agronomic behavior of the variables studied, the levels of green manure affected oat yield, mainly the number of tillers, which in turn affected the dry matter yield, finally the oat varieties have a differential behavior with the change in the levels of green manure.

Present study was carried out to screen the cowpea genotypes and to determine the effect of different level of aluminium on morpho-physiological, growth, yield and quality attributes. Twenty cowpea genotypes with four aluminium levels i.e. 0, 20, 40, 60 ppm in three replications was investigated in factorial complete randomized block design. Individual main effect and their interaction effects were studied for plant height at weekly interval, biomass, number of nodule per plant, root length, shoot length, dry matter of root, shoot, leaf, total dry matter, number of pod per plant, pod weight, yield and seed protein content. Cowpea genotypes exhibited significant differences for all 13 observed traits. Aluminium treatment expressed significant differences for all the attributes under study except biomass per plant. However, interaction effect was found to be significant for all studied characters except plant height at all stages. Among the aluminium treatments; observed traits were performing better at 20 ppm of Al, whereas, pod yield and protein content were best under the control.

ABSTRACT This study aimed to evaluate the effect of sequential applications of plant regulators on growth and seedhead emergence of Bahiagrass (Paspalum notatum). The study was carried out on a 15-month-old lawn, in a randomized block design, with four replicates. The treatments consisted of the following plant-growth regulators and dose: trinexapac-ethyl in sequential application of 113 + 113, 226 + 113, 226 + 226, 452 + 113, 452 + 226, 452 + 452 g a.i. ha-1; trinexapac-ethyl in single application of 678 and 904 g a.i. ha-1; and prohexadione-calcium in sequential application of 100 + 100 and 200 + 200 g a.i. ha-1, besides a control, with no application. The effects of treatments were evaluated based on visual injury, plant height, height and number of flower rachises and total dry matter production of clippings. Sequential applications of prohexadione-calcium at 100 + 100 or 200 + 200 g a.i. ha-1 were efficient to reduce plant height, but did not show efficacy to reduce the number and height of seedheads or the total dry matter of clippings of Bahiagrass. However, Bahiagrass lawns can be managed by trinexapac-ethyl sequential applications of 452 + 452 g a.i. ha-1 or single application of 904 g a.i. ha-1, with reduction in the need for mowing for a period of up to 113 days after application, without causing any deleterious effect on the visual aspect of the lawn.

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).

The objective of this study was to identify the hybrids of sorghum most suitable for the production of silage in the semiarid regions of northeastern Brazil. Twenty-three hybrids were evaluated in a randomized block design with three replicates. The dry mass yield; dry mass of leaf, stem, panicle, grains, and senescent matter; and chemical composition of the plant were evaluated. The pH, ammoniacal nitrogen (N-NH3), and chemical composition of the silage were also assessed. The hybrids 947252, FEPAGRO 18, 12F042226, and SF 11 performed best in terms of morphological characteristics, with the highest mass of leaves and grains. The hybrid FEPAGRO 19 had the highest dry matter value (443.3 ± 17.0 g kg-1), whereas the hybrid 12F042496 had the lowest value (271.3 ± 17.0 g kg-1). The dry matter (DM) content of the other hybrids was within the recommended values for silage production (280 to 400 g kg-1). High levels of crude protein were observed in the grouped hybrids 12F042496, 947254, and 12F042422. The hybrid 12F042496 had the highest neutral detergent fiber content. The hybrids 9929036, 9929030, 9929012, 947254, 947072, PROG 134 IPA, 12F042226, 12F042422, and BRS 506 had pH values ranging between 3.8 and 4.2, indicating good quality silage. Overall, the sorghum hybrids 9929030, 12F042224, 12F042150, FEPAGRO19, and FEPAGRO11 had the best growth and production characteristics, and plant and silage chemical composition, and are thus recommended for the production of silage in the semiarid of northeastern Brazil.
