The effects of applying a wheat straw mulch at various rates to a trash-free summerfallow field immediately after seeding spring and winter wheat were studied for 9 years. Rates of 4000 and 5000 lb or more per acre significantly depressed mean yields of spring and winter wheat, respectively. Straw at rates of 4000 to 5000 lb completely shaded the soil surface when spread uniformly. Higher rates delayed maturity up to 4 to 6 days, shortened height of plants, occasionally lowered nitrate production, and had a negligible effect on plant population and percentage protein of the grain. Each 1000-lb increment of bright straw depressed the late-morning temperature in the 4- to 8-in. depth of soil by an average value of 0.51° F during the early growth period. The depression increased with the season to a value of 0.65° F by mid-June and then decreased to a value of 0.25° F by mid-July, when the crop, in the headed-out stage, almost completely shaded the soil surface.A quantity of mulch up to 4000 lb per acre can be used without deleterious effects on the crop. Quantities of 4000 lb or more should be managed so that the soil temperature depression associated with complete shading of the soil is avoided.

Wheat Straw Mulch

The presence of wheat straw mulch in no-tillage systems can increase corn yields in the central Great Plains, but information is needed on the optimal mulch level and the toxicity of metolachlor on corn growth. Research was conducted to determine the effect of winter wheat straw mulch levels of 0, 1.7, 3.4, 5.1, and 6.8 t ha–1and metolachlor rates of 0, 0.5, 1.0, and 1.5X-rates on corn growth and yield in a winter wheat-ecofallow-corn-fallow rotation at three locations across Nebraska. Response of corn to different mulch levels and metolachlor rates varied with climate and location. In general, early corn growth was retarded by increasing amounts of mulch due to reduced soil temperatures, but after tasseling corn grew taller under increasing mulch levels because of increased soil moisture. Soil water content, kernel moisture at harvest, stover dry matter, total dry matter, ears per plant, and kernel weight increased with increasing mulch level. Corn grain yield reached a maximum at a mulch level of 5.1 t ha–1. Kernel weight, kernel number, and grain yield increased with higher mulch levels and 0.5 and 1.0X metolachlor rates as weed competition was reduced, but decreased at the 1.5X-rate of metolachlor due to corn injury. Lack of sufficient growing degree-days to compensate for lower soil temperatures or corn injury reduced corn yields at the higher mulch levels and 1.5X-rate of metolachlor in west-central and western Nebraska. From a practical standpoint, a mulch level of 3.4 to 5.1 t ha–1and a metolachlor rate near the X-rate should increase corn yield (14 to 15%) over unmulched corn in the central Great Plains.

Soil Losses

The study aimed to evaluate the effect of the straw mulch and compost application on the soil losses in potatoes cultivation. The three-year (2016–2018) exact field plot trials with the potato cv. Dicolora was carried out at the experimental station in Prague-Uhříněves. Wheat straw mulch in two doses 2.5 t/ha (SM1) and 4.5 t/ha (SM2) was applied on the soil surface; the compost in a dose of 20 t/ha (CM) was shuffled to the surface soil layer. Both straw mulch and compost application contributed to the significant reduction of the soil losses compared to control untreated (C). In the average of 2016–2018, the lowest soil loss 17.54 g/m<sup>2</sup> (amount of the soil sediment caught) was found for the variant with the straw mulch treatment (SM2); it means the decrease of soil losses by 71.9% compared to C. Variant SM1 (lower rate of straw mulch in dose 2.5 t/ha) showed the soil loss 18.6 g/m<sup>2</sup> (the decrease by 70.2% compared to C). The similar results for both variants indicate that for effective soil protection, it is not necessary to use the high doses of the straw mulch. Regarding the distribution of precipitation during the vegetation season, intensive precipitation during the short time, especially when they came after the longer period of drought led to higher soil losses compared to the precipitation distributed regularly.

SummaryGrain yield of winter barley in the year preceding the experiment (1978) was relatively uniform over the site. In 1978–9 after the drainage treatments had been introduced, growth and yield of winter wheat were not affected by drainage, probably due to a compact layer at 20 cm that prevented the mole drains from controlling the water table (Harris et al. 1984).In 1979–80 after disrupting this layer, root growth in undrained plots during the winter and spring was severely restricted by the presence of a water table 20 cm from the soil surface, although some root axes were able to grow down to 75–100 cm below the soil surface. The differences in root distribution patterns between drained and undrained plots disappeared after the water table declined in April. Uptake of nitrogen, phosphorus and potassium were less on undrained plots. Dry-matter production, leaf area index and peak number of tillers was also depressed, so that the yield of winter wheat was 0·74 t/ha greater on the drained treatment; the grain from the drained plots contained fewer impurities and weed seeds.

Research was conducted to determine the effect of winter wheat (Triticum aestivumL.) straw mulch level on weed control in a winter wheat-ecofallow corn (Zea maysL.)-fallow rotation at North Platte and Sidney, NE, in 1981 and 1982. Wheat straw mulch was established at 0, 1.7, 3.4, 5.1, and 6.8 Mg/ha in stubble fields. After application of 1.5 times the recommended rate at corn planting, metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] concentration remained higher in unmulched soil than in mulched soil for more than 4 months, due to interception of metolachlor by the mulch. Even though the amount of metolachlor in the soil was reduced by mulch, weed control was not reduced and increased with increasing mulch level. Thus, increasing metolachlor rate was not necessary to maintain adequate weed control in no-till winter wheat stubble since mulch itself provided some measure of weed control.

Adoption of suitable organic fertilizers and soil mulching are useful tools to enhance soil quality, which will inevitably lead to improved growth and yield of crops. Little is known about the soil organic amendments and Azolla (Azolla pinnata) under soil organic mulching on the growth and yield of squash plant (Cucurbita pepo L.). A comparative study mainly focused on the impacts of organic fertilizer treatments on soil fertility and squash growth under wheat straw mulch was conducted on wooden boxes filled with silty loam soil. Wheat straw, as an organic mulch, and five organic-fertilization treatments were added to the soil. Wheat straw with a size of <2 cm was added to the soil surface with a 2 cm thickness. The fertilization treatments were: control (CO), chemical fertilizer (CF), compost (CT), vermicompost (VC), and dry Azolla (DA). Wheat straw mulch had positive effects on the soil properties, growth, and yield. The maximum fruit yield was obtained from the soil fertilized with DA under wheat straw mulch, while the lowest one was found in the control without mulching. Azolla and organic fertilizers showed a remarkable superiority over the mineral fertilization in increasing the soil fertility as well as the growth and quality of squash fruits; this superiority increased under the wheat straw mulching system. The application of recommended mineral fertilization (CF), compost (CT), vermicompost (VC), and dry Azolla (DA) under wheat straw mulch increased the soil available-N by 2, 20, 12, and 29%, respectively, above the control (CO), while these organic fertilizers without mulching increased the soil available-N by 11, 32, 26, and 48%, respectively. The production of vegetable crops such as squash plants requires the addition of organic fertilizers and mulching to increase yield and quality of fruits.

Population Suppression

The research to observe the effect of the kinds and thickness of organic mulch toward the population of weeds and melon yield was conducted in Wringin, Purwobinangun, Pakem, Sleman District of Yogyakarta, at February up to May 2004. The research site has the 500 m above sea level altitude and the Regosol soil type. The field experiment was arranged in a single factor Randomized Completely Block Design with three blocks as replications. The treatments of mulch kinds consisted of 8 levels which are: no mulch application, plastic mulch, straw mulch with 4 cm, 8 cm, and 12 cm thickness, bamboo leaves mulch with 4 cm, 8 cm, and 12 cm thickness. The effect of treatments on weeds population suppression, melon growth and yield were observed during the growth period. The result showed that the bamboo leaves mulch with 8 cm thickness and plastic mulch significantly suppressed weeds population until 67 days after planting in compared with the other treatments. Straw mulch and bamboo leaves mulch significantly increased the component of melon yield, but the kind and thickness of organic mulch was not significantly affected the growth and yield of melon.

The climate changes and increased drought frequency still more frequent in recent periods bring challenges to management with wheat straw remaining in the field after harvest and to its decomposition. The field experiment carried out in 2017–2019 in the Czech Republic aimed to evaluate winter wheat straw decomposition under different organic and mineral nitrogen fertilizing (urea, pig slurry and digestate with and without inhibitors of nitrification (IN)). Treatment Straw 1 with fertilizers was incorporated in soil each year the first day of experiment. The Straw 2 was placed on soil surface at the same day as Straw 1 and incorporated together with fertilizers after 3 weeks. The Straw 1 decomposition in N treatments varied between 25.8–40.1% and in controls between 21.5–33.1% in 2017–2019. The Straw 2 decomposition varied between 26.3–51.3% in N treatments and in controls between 22.4–40.6%. Higher straw decomposition in 2019 was related to more rainy weather. The drought observed mainly in 2018 led to the decrease of straw decomposition and to the highest contents of residual mineral nitrogen in soils. The limited efficiency of N fertilisers on straw decomposition under drought showed a necessity of revision of current strategy of N treatments and reduction of N doses adequately according the actual weather conditions.

Lentil (Lens culinaris) is an important winter season annual legume crop known for its highly valued seed in human and animal nutrition owing to its high lysine and tryptophan content. Shortage of water during the crop growth period has become the major impediment for cultivation of pulses in rice fallow in particular. Under such conditions, the application of hydrogel can be a potential alternative to improve photosynthetic efficiency, assimilate partitioning, and increase growth and yield. A field experiment was conducted from November to February during 2015–16 to 2017–18 on clay loam soil that was medium in fertility and acidic in reaction (pH 5.4) at Central Agricultural University, Imphal, Manipur. The experiment was laid out in split plot design with three replications. There were three hydrogel levels in total in the main plot and foliar nutrition with five different nutrient sprays in sub-plots, together comprising 15 treatment combinations. The data pooled over three years, 2015–2018, revealed that application of hydrogel at 5 kg/ha before sowing recorded a significantly greater number of pods per plant (38.0) and seed yield (1032.1 kg/ha) over the control. Foliar application of nutrients over flower initiation and pod development had a positive effect on increasing the number of pods per plant eventually enhanced the seed yield of lentil. Foliar application of either 0.5% NPK or salicylic acid 75 ppm spray at flower initiation and pod development stages recorded significantly more pods per plant over other nutrient treatments. Further, the yield attributed improved because of elevated growth in plant. Significantly maximum seed yield (956 kg/ha) recorded in the NPK spray of 0.5% remained on par with salicylic acid 75 ppm (939 kg/ha) over the rest of the treatments.
