O objetivo deste trabalho foi avaliar a resposta do feijoeiro de inverno à irrigação e doses de adubação nitrogenada, em sistema plantio direto, no município de Aquidauana-MS. O experimento foi conduzido na Unidade Universitária de Aquidauana - Universidade Estadual de Mato Grosso Sul (UUA/UEMS), utilizando-se o cultivar de feijão Pérola semeado em junho de 2006. Utilizou-se o manejo de irrigação baseado nas leituras do tanque Classe A, com 3 momentos de se proceder a irrigação, com lâminas de 16,5; 27,6 e 30,5 mm, correspondendo a 50, 30 e 27% de reserva de água no solo, respectivamente; e quatro doses de adubação nitrogenada (0, 50, 100, 150 kgha-1 de N). O delineamento experimental utilizado foi o de blocos casualizados, com parcelas subdivididas, composto por três blocos e duas replicações dentro de cada bloco. Pode se concluir que, com a lâmina de irrigação de 16,5 mm e 100 kg de N ha-1, o feijoeiro teve a melhor produtividade, em torno de 3278 kg ha-1. UNITERMOS: Phaseolus vulgaris, tanque Classe A, evapotranspiração.  OLIVEIRA, G.

IRRIGATION AND NITROGEN DOSES IN DRY BEAN WINTER CROP UNDER NO TILLAGE SYSTEM IN AQUIDAUANA, STATE OF MATO GROSSO DO SUL  2 ABSTRACT The dry bean crop in the winter has become important for presenting yield above the annual average, mainly due to the technological increments in the past years,  like irrigation. The objective of this research was to evaluate the response of the dry bean crop to irrigation and nitrogen fertilization, under no tillage system. The research was carried in the experimental area of the Universidade Estadual de Mato Grosso do Sul - Aquidauana - MS (UUA/UEMS), using Perola cultivar sowed in June, 2006. Irrigation management was based on the readings of a Class A pan, with 3 irrigation times, water depths of 16.5mm; 27.6mm and 30,5 mmcorresponding to 50, 30 and 27% of water soil reserve, respectively; and four nitrogen fertilization doses (0, 50, 100, 150 kgha1 of N). The experimental design had randomized blocks in split plots. It can be concluded that with irrigation depth of 16.5 mmand 100 kgN ha-1, the dry bean had the best grain yield, around 3.278 kg ha-1. KEY WORDS: Phaseolus vulgaris, Class A pan, evapotranspiration.

Soil Preparation

Mechanical soil management has a huge impact on early plant development and can promote effects at all stages of the silage forage production cycle. Thus, this work was conducted to verify if a mechanized system of soil preparation influences the accumulation of pigeon pea and corn biomass. The experiment was conducted at the farm school of Federal University of Mato Grosso do Sul, Faculty of Veterinary Medicine and Animal Science. The experimental delimitation chosen was randomized blocks, the treatments were two systems of tillage (conventional and reduced), associated to two crops (Cajanus cajan L., cv. BRS Mandarim e Zea mays L. hybrid TG Status). The cv. BRS Mandarim in conventional tillage system impacted higher biomass values. In addition, the same soil preparation system promoted oscillations between the crops (P<0.05), where cv. BRS Mandarim showed biomass values 7% higher than cv. Status TG. In reduced handling system, the crops presented the same biomass productivity. Despite the increase of dry weight during the cycle of cv. BRS Mandarim biomass production, there was a reduction in the dry matter fraction, indicating that the specific weight per plant decreased at the end of the evaluation period. The tillage system that was fulfilled conventionally promoted higher estimates of pigeon pea biomass. Corn was not influenced by mechanized tillage system.

Tillage System

Field experiments were conducted to determine the effects of tillage system and rimsulfuron application on weed flora and growth of maize (Zea mays L. Mitic F1) at a site with no history of pesticide use for the last 5 years. A randomized complete block design was employed with three replicates per treatment (conventional tillage without rimsulfuron application (control), no-tillage with rimsulfuron application (NT+Rim) and conventional tillage with rimsulfuron application (CT+Rim)). The lowest leaf area index, dry weight and yield of maize were recorded in NT+Rim plots. In addition, the highest soil bulk density was determined in NT+Rim plots. Moreover, the rimsulfuron application resulted in significant reduction in the root growth and arbuscular mycorrhizal (AM) colonization. The lowest root biomass, root length density, root surface and AM root colonization was found in CT+Rim plots. The lowest weed number and biomass was also observed at CT+Rim plots. Sustainability yield index (SYI) shown that the maize crop is more stable under conventional tillage compared with no-tillage. Our results indicated that root growth was reduced significant by rimsulfuron application but statistically significant lower maize yield was obtained in no-tillage system.

Maize Populations

Drought and low nitrogen are major stresses for maize (Zea mays L.), and maize populations from the Sahara Desert are potential sources of stress tolerance. The objectives were to assess the tolerance and varietal and heterosis effects of Algerian populations under no-nitrogen fertilization and water stress. A diallel among six Algerian maize population was evaluated under drought (300 mm irrigation) vs. control (600 mm) and no-nitrogen fertilization vs. 120 kh ha−1 N fertilization. Genotypes showed significant differences and genetic effects for water- and nitrogen-stress tolerance. We propose a reciprocal recurrent selection to take advantage of additive and non-additive effects, using AOR and IGS, since they showed good performance in optimum and stress conditions, for improving yield heterosis for AOR × IGS. Negative effects are not expected on plant height, anthesis–silking interval or early vigor. These populations and BAH could be sources of inbred lines tolerant to drought and no-nitrogen fertilization. There was no relationship between origin and genetic group and stress tolerance per se or as parents of tolerant crosses. These populations and crosses could be used as base material among Algerian populations, for breeding programs focusing on tolerance to water or nitrogen stress.

ABSTRACT The previous cultivation of green manures and mechanical soil decompression are options to minimize compaction of the topsoil in no-tilage system (NTS) set in different production systems in the Brazilian Savannah. In addition, it is essential to relate these agricultural practices with the economic benefits generated through the production cycles. The objective of this study was to evaluate economically the effect of sporadic mechanical decompression of the soil and previous cultivation of green manure in the production and net gain margin of upland rice and "winter" common bean, under sprinkler irrigation, in NTS in lowland Brazilian savannah. This study was developed in the 2012/13 harvest and 2013 winter in Selvíria, state of Mato Grosso do Sul, in an clay texture Oxisol in the savanah in the state of Mato Grosso do Sul, in a randomized block design arranged in a 5 x 2 factorial arrangement with four replications. The treatments were a combination of five green manures (fallow (control), Cajanus cajan, Crotalaria juncea, Pennisetum glaucum and Urochloa ruziziensis) with and without mechanical soil scarification. The yields of upland rice and common bean grains were not influenced by the previous green manure cultivation; the upland rice grown in succession to Cajanus cajan in the presence of mechanical soil scarification provided greater increase in grain yield and higher gross margin profit. Beans cultivated in succession to Crotalaria juncea and Pennisetum glaucum in the presence of mechanical soil scarification, followed by rice cultivation, provided greater increases in grain yield and gross profit margins.
