The crop yield is related to several factors, among these, soil tillage, compaction and rotation. This study aimed evaluate the winter cover crops rotation influence on physical properties grain of dry beans, maize soybean for two growing seasons. Three experiments were conducted, corresponding crops. It was used randomized block design with three treatments four replications consisted by 3 × 10 m plots. were: systems in no-till, control, consisting fallow conventional tillage. matter,...
The weeds if not properly controlled have great ability to settle in agricultural systems, affecting crop production. objective of this work was determine the interference and level economic damage different density crop. treatments were composed canola hybrids (Hyola 50, Hyola 76, 433, 571 CL, 575 CL Diamond) twelve infestation turnip variables evaluated estimate competitiveness plant density, leaf area, soil cover dry mass turnip. Grain yield, price, herbicide efficiency, control cost used...
Maize is one of the world's major cereals, and alexandergrass most damaging weed in crop. The objective this work was to evaluate relative competitive ability maize hybrids presence through replacement series experiments. experiments were set up a complete randomized block design, with four replications. Firstly, for as well alexandergrass, plant population determined which final production becomes constant. composed plastic pots capacity 8 dm3, each experimental unit placed proportion...
In the soybean crop occurs high losses of grains production, in function weeds.It is noteworthy that among most damaging weeds alexander grass (Urochloa plantaginea).The objective project was to test mathematical models and identify explanatory variables determinate level control estimated cultivars populations competitor.The experiment installed UFFS experimental area Erechim, RS agricultural year 2016/17.The treatments were composed (NS 5445 IPRO, NS 5959 SYN 13561 1059 RR e BMX Elite...
ABSTRACT: The objective of this work was to evaluate the interference and determine level economic damage (NDE) weed when infesting corn crop. Treatments were composed by densities (2.60, 3.10, 3.65, 4.00 4.80 plants m-1) 10 Alexandergrass populations for each crop seeding density. population plants, leaf area, soil cover shoot dry mass evaluated as indicator infestation. Shoot presents better adjustment model rectangular hyperbole, losses grain yield due satisfactorily estimated model. Corn...
The objective of this work was to determine the periods interference turnip, ryegrass and black oats infesting canola crop.Two models were studied: first, cohabited with weeds for increasing up until 0, 7, 14, 21, 28, 35 42 days after emergency (DAE) throughout cycle; second, culture kept free infestation same described previously.At 51 DAE, variables related weed morphophysiology determined.In harvest crop, measured number siliques, a thousand grain mass yield.The physiological variables,...
The seeds physiological quality is a fundamental characteristic to obtain competitive and productive plants, where treatment an important tool keep high-quality.The present study aimed evaluate chemical treatments storage period influence on quality.It was used factorial (4 x12) randomized complete block design, with eight replications.In factor A, the chemicals (thiamethoxam, metalaxyl + fludioxonil thiabendazole pyraclostrobin thiophanate-methyl fipronil) control.In B, treated periods (0,...
Canola (Brassica napus L. var. oleifera) is a winter growing option for producers, however, harvesting the phase that requires most care and decision making to avoid losses in productivity.One of alternatives can be used solve this problem application maturing herbicides.Thus, objective study was evaluate physiological quality canola seeds with use herbicides, applied two seasons, pre-harvest maturation crop.The experimental design randomized block design, arranged factorial scheme 7x2 + 2...
