The objective of this study was to compare three fallow-tillage systems for moisture conservation and early vs. late seeding dates on subsequent grain yield of wheat. The tillage treatments were (1) a fall chisel operation followed by a spring chisel tillage, (2) chiselling twice in the spring in perpendicular directions, and (3) moldboard Author: Thomas G.

(–, and ) to evaluate tillage and tillage timing eﬀ ects on soil water storage, crop water use, and grain yield of winter wheat (Triticum aestivum L.) and spring green pea (Pisum sativum L.) in rotation, was conducted near Pendleton, OR. However, use of cultivator in general gave maximum pods per plant (), grains per pod (), grain weight ( g) and seed yield ( kg/ha) with 37.

Such minimal tillage is possible, in part, because the soil has frequently been observed as being looser or more "mellow" after a crop of soybeans.
The advantages for such a tillage system would include reduced energy consumption as well as earlier seeding, a factor which is very important to the successful production of winter wheat. Lorenz, R. Lal, in Advances in Agronomy, Tillage.
Tillage effects on gaseous emissions vary among farming systems, soil type, and climate. For example, in a mixed cropping system, tillage and fertilizer management had no effects on monthly N 2 O emissions for fertilized and unfertilized NT with weed cover mulching and CT during a 3-year observation period (Yagioka et al., ).
Grain yield, straw biomass, root biomass and crop residue were largely influenced by tillage practices, crop type and planting year. With regard to the tillage effect, NT, ST, PT/NT, NT/ST and ST/PT significantly enhanced grain yield by %, %, %, % and % (p.
This system would provide greater soybean yields while allowing adequate time for an optimum wheat planting date after soybean harvest. However, for later soybean plantings (after mid-May), early-maturity varieties can be used without a soybean yield penalty while allowing adequate time for wheat planting.
Figure 1. wheat yield potential increases, the previous crop has less effect on wheat yield. ( through at Lexington, Kentucky, data provided by John Grove) 40 60 y = x + R2 = y = x - R = 80 Average Wheat Yield (bu/acre) Wheat Grain Yield (bu/acre) Wheat after corn Wheat.
Whereas a good seed bed preparation is necessary when wheat follows rice. It was also observed that all the tillage implements remained at par statistically when parameters like no. of tillers, grains weight, grain and straw yields were considered ().However, rotavator produced the maximum no.
of tillers ( m-2), grains weight ( g), yield of grain ( t ha-1) and straw. If Hessian fly is a concern, delay seeding of winter wheat until after Hessian fly flights are reduced by cool fall temperatures, usually early to mid October.
However, remember that delaying the winter wheat seeding date past the optimum seeding time also reduces yield potential and erosion protection benefits. This is not possible with conventional tillage as that is time consuming.
So it is highly suited to areas where two or more crops are rotated on the same land within the year. In much of south Asia yield in wheat reduces rapidly as sowing time is delayed beyond the optimum date for the area (see Hobbs et al. for details). So delay costs yield.

spring finish tillage was completed. Hourly soil temperature (two-inch depth in seed zone) was recorded on four tillage systems from April 20 to May 9, Average soil temperatures were calculated.
Soil moisture was determined from two-inch deep soil samples collected on May 9, This date was considered acceptable planting for strip.
hard red winter wheat seeded at recommended seeding rates is projected to be cm. Seeding rates alone did not influence grain yield much but suitable combination of seed rate and row spacing could increase grain yield of wheat (Marshall and Ohm, ).
Variation in planting time, 31 October (D 1) and 7 and 10 November (D 2), was used to evaluate effect of planting-earliness. Under D 1 in NT, grain yield of wheat was comparable to that under D 2 in CT.
However, under no advancement of wheat planting in NT, grain yield was – t. A field study was undertaken to evaluate the effects of tillage on germination patterns and grain yield of yellow field peas and chickpeas.
Trial Summary. The study was conducted at the Henry J. Stumpf International Wheat Research Center at. Little research has examined the influence of tillage system on root growth in wheat grown on rainfed Vertisols. A 3-year field study (, and ) was carried out on a typical Vertisol (southern Spain), to determine the effects of tillage system on root growth in spring wheat (Triticum aestivum L) grown in continuous rotation with faba bean (Vicia faba L), within the framework of the.
Corn grain yields ranged from to Mg ha −1 and were significantly greater following mid or late kill, compared with early kill of vetch, regardless of corn planting date or FN rate. Gravimetric soil water under mid‐ or late‐kill vetch was often significantly greater than after early‐kill vetch.
How Seeding Date Affects Tiller Development Date of seeding greatly affects development of tillers in winter wheat, the source of as much as 70% of the grain yield in a normal year.
Seeding during the optimum period enables wheat to form sufficient but not excessive tillers.

soils. Improved wheat yields from in-row subsoiling for soy-beans, however, did not result in yields equal to those. ob tained with deep tillage (chisel or turn) prior to planting wheat at any location. Soybean yield. Tillage prior to planting wheat did not have an effect on soybean yields except on the Dothan and Benndale soils (Table 2).
Moreover, rice-wheat cropping system is also dominant production practice in the area. Delayed wheat sowing due to late harvest of the preceding crop, is one of the common drawbacks of both the systems that may affect wheat yield.
Sowing wheat after mid November causes reduction in grain yield at 35 kg ha-1 day-1 (Hobbs and Gupta, ). Besides. tillage and planting methods effects on yield, water use efficiency and profitability of soybean–wheat system on a loamy sand soil - volume 49 issue 4 - hari ram, yadvinder singh, k.
saini, d. kler, j. timsina. conditions. They found wheat yield in the conventional tillage system and direct drill as kg ha-1, kg ha-1 and kg ha-1, kg ha-1 in the first and second years, respectively.
The objective of this study was to determine tillage effects and energy efficiencies of alternative tillage and direct seeding on yield of wheat. For example, a winter wheat-spring cereal-winter legume rotation might be used where the spring cereal is seeded after winter wheat under minimum tillage.
Then, a no-till system is used for planting the winter legume after the spring grain, and winter wheat after the winter legume. (Halvorson et al., ). The WF tillage treatments were as in each plot and subtracting grain yield.
All grain yields were follows: determined by harvesting a minimum of a by m area from each plot with a plot combine. Organic C input was 1. CT: sweep tillage with Haybuster1 undercutter as needed. Wheat yield dynamic in Canada, USA, Russia and Kazakhstan from till was related to air temperature and precipitation during wheat season to evaluate the effects of climate change.
The study used yield data from the provinces, states and regions and average yield from 19 spring wheat breeding/research sites. Both at production and research sites grain yield in Eurasia. Tilling grain sorghum residue before planting wheat appeared to reduce the negative effects of sorghum residue and increase wheat yields.
It is possible that these tillage operations reduced the nitrogen and water competition of the grain sorghum on the following wheat crop. Averaged across the years, grain yield of rice under the CT system ( t ha−1) was significantly higher than ZT ( t ha−1). Increased level of wheat residue retention increased grain yield consistently in all three years.
Grain yield was not influenced by systems of weed management.With spring wheat, a yield loss of about 1/2 bushel per acre per day can be expected if planting occurs after April All spring grains should be sown with a grain drill to a depth of 1 to /2 inches.
The optimal seeding rate for oats is 96 pounds or 3 bushels per acre, whereas spring barley and spring wheat do best at 2 bushels per acre.Lower yield level of spring wheat in simplified tillage was influenced by the weather conditions in the period of sowing and plant emergence in April and at the beginning of May.
During this period there was a shortage of precipitation as well as a high air temperature. In no effect of the tillage method on spring wheat grain yield was found.
