B Uptake

Boron sufficiency supply to plant in calcareous soils of arid regions is severely reduced under arid climatic conditions. Therefore, this study was conducted to determine the effect of Boron (B) fertilization on yield of Wheat grown in calcareous soils of arid regions. Boron was added at two rates namely 0 and 0.5 mg B kg-1 soil to three most common textured class’s soils. Straw and grain yield was determined on oven dried basis. B content of plants was determined as well. Straw and grain yield of wheat was significantly increased by (67.0 and 87.1%), (24.5 and 82%) and (64.5 and 48%) under the addition of 0.5 mg B Kg-1 soil over that of no B addition to clay, loam and sandy loam soil, respectively. Results also showed that wheat grown on the coarse-textured soil had the least B uptake per pot compared to loam and clay textured soils. B content in straw and grain was increased by (77.4 and 121%), (81.2 and 157%) and (184 and 96.9%) under B addition compared to those of zero B addition to clay soil, loam soil and sandy loamy soil, respectively. Response to B addition, significantly, increased in all soils due to increase of available B content in soils which may suggest the importance of adding adequate rate of B application under cropping system of arid regions.

Semi Arid

Underground irrigation water, particularly saline, when in arid and semi-arid regions of India may contain toxic amounts of B, from a trace up to 10 mg B/l (Anon. 1981–82). Continuous use of such water for irrigation may lead to the accumulation of salts and B in soil and this creates toxicity problems. Kanwar & Mehta (1970) have reported that water containing 2 mg B/l is hazardous if used on heavy soils. For sandy loam soils of semi-arid tracts in India, Chauhan & Powar (1978) have reported reductions in the grain yield of wheat and pea at 4 and 6 mg B/l respectively, while under similar conditions grain yield of lentil and barley was reduced at 3 and 6 mg B/l respectively (Chauhan & Asthana, 1981). So far, few attempts have been made to evaluate the effect of boronated saline water on soil and crops, under different agroclimatic conditions. A study of the effect of boronated saline water on an important oil-seed crop, linseed, on alkaline sandy loam soil in the semi-arid region of Agra, India was therefore undertaken.

Field studies on a sandy loam soil determined the influence of application method and rate and subsequent tillage on corn response to imazaquin and imazethapyr residues remaining in the soil. Imazaquin was applied preplant incorporated (PPI) and preemergence (PRE) at 70, 140, and 280 g ai/ha and postemergence (POST) at 70 and 140 g/ha. Imazethapyr was applied PPI and PRE at 70, 105, and 140 g ai/ha and POST at 70 and 105 g/ha. Subsequent tillage included fall moldboard plowing followed by spring field cultivation, fall chisel plowing followed by spring field cultivation, and no tillage. Herbicide dissipation was determined by analyzing soil cores taken in the spring at the time of corn planting and by measuring corn height and grain yield. Imidazolinone residues were detected in only 1 of 2 yr. Imazaquin was detected more frequently than imazethapyr. Imazaquin concentrations in the upper 10 cm of soil 11 mo after a PPI application of 280 g/ha were 5, 6, and 7 ng/g of soil in moldboard plow, chisel, and no-tillage systems, respectively. Imazaquin (5 ng/g) was also detected in the 10–18-cm soil depth in the moldboard plow system. Corn height and grain yield were not reduced from imazaquin or imazethapyr, regardless of application method or rate in any tillage system.

SUMMARYField experiments were conducted on two soils (clay loam and sandy loam) with varying texture and water table depth to study the effects of two planting methods (dry seeding and transplanting) on the root growth and grain yield of rainfed lowland rice. About 75% of the roots were found in the top 10 cm soil. Root length density at the flowering stage and grain yield in the sandy loam soil, with a water table deeper than 1.5 m, were less in dry-seeded than in transplanted rice, probably because of the greater moisture stress in dry-seeded rice between late tillering and harvest. In the clay loam soil, with the water table mostly at the soil surface, there was no difference in grain yield between dry-seeded and transplanted rice.

Abstract A field experiment was carried out in a farmer’s field in Zakhikha which is one of the rural areas of western Heet City (about 15 kg) in Anbar Governorate, during Winter season 2020-2021, with sandy loam soil, to study seven newly derived genotypes from durum wheat, including two cultivars. They are registered, certified, and commonly cultivated in Iraq, under three seeding rate to select the ones that are suitable for the conditions of Anbar Governorate. Randomized complete blocks design (RCBD) was used in a split plot arrangement with three replications. The experiment included three Seeding rate (140, 160 and 180 kg ha-1) that represented the main plot, whereas the sub plots were occupied by seven genotypes (Latifia, Babel-30, Babel-31, Babel-32, Babel-86, and the two approved varieties Dour-29 and Dour-85). The results of the study showed that Babel-32 outperformed the rest of significant effect genotypes with highest average number of spikes (507.6 spike m-2) and grain yield (8.741 Mg ha-1), while the genotype Babel-86 was superior in weight of 1000 grain (55.89 g), and the cultivar (Dour-29) outperformed for the trait of number of grains per spike (39.15 grains spike-1). A significant effect of plant densities appeared in the studied traits, as the plants grown at seeding rate (180 kg ha-1) recorded the highest average in the trait of number of spikes m-2 (506.2 spike m-2) and grain yield (8.898 Mg ha-1) And the percentage of protein (11.89%). While planting plants at seeding rates (140 kg ha-1) led to the highest rate of number of grains per spike (38.42 grains) and 1000 grains weight (52.71 g). There was a significant interaction between genotypes and Seeding rate.

Abstract: The objective of this work was to evaluate carbon and nitrogen mineralization in the soil after the application of composts produced in an automated composting plant, using pig slurry (PS) with and without the addition of retorted oil shale (ROS) and dicyandiamide (DCD) during composting. Laboratory studies were carried out for 180 days on two soils with contrasting characteristics: sandy-loam Typic Paludalf and clay Rhodic Hapludox, which were managed for more than 10 years under a no-tillage system. The composts were thoroughly mixed with the soils. The mineralization of the C and N from the compost was evaluated by measuring continuously CO2 emissions and periodically mineral N (NH4+ + NO3-) content in the soils, respectively. The mineralization of the C from the compost without ROS and DCD was higher in the sandy-loam soil (20.5%) than in the clay soil (13.9%). Similarly, 19.4% of the total N from the compost was mineralized in the sandy-loam soil and 10.9% in the clay soil. The presence of ROS in the compost reduced C mineralization by 54%, compared with the treatment without additives, in the sandy-loam soil and caused net N immobilization in both soils during incubation. The addition of DCD during PS composting did not affect the mineralization of the C and N from the compost in both soils. The addition of ROS during the composting of PS favors the retention of the C from the compost in the soil, especially in the sandy-loam one, but results in a net N immobilization.

Maintenance of soil quality is considered to be the key to attain sustainability in agricultural production and thus to achieve food security. In this study we tried to answer a research question as to whether integrated application of inorganic and organic sources of nutrients can maintain productivity and soil quality in rice-rice cropping system. To address this, total 27 physical, chemical (including organic C and soil fertility parameters) and biological (including enzyme activities) properties of an acidic sandy loam soil, which were subjected to different nutrient management (NM) practices for nine years of rice-rice cropping under submergence in subtropical India were critically assessed. Seven NM practices comprised of organic [farmyard manure (FYM)], inorganic fertilizers (sources of N, P, K, S, Zn, and B) and some of their combinations were tested using randomized complete block design with four replications. Integrated use of inorganic fertilizers (NPK) and organic manure (FYM) sustained productivity of rice-rice cropping system and aggraded soil quality as compared to only inorganic fertilizers even with inclusion of S, Zn and B. The NPK+FYM was superior among the NM practices to improve physical, chemical and biological properties of soil. Cation exchange capacity, non-exchangeable K and microbial biomass C were screened as the most sensitive attributes for assessing soil quality. Although the present study demonstrated the positive influence of integrated NM, application of even 80-17.5-50 kg N-P-K along with 5 Mg FYM ha-1 in each rice season failed to maintain total K content in soil. This suggested for readjustment of dose of inorganic fertilizers and organic manure and their application schedule for adequate replenishment of K in acidic sandy loam soil under rice-rice cropping in subtropical climate.

The effects of different herbicide combinations: control (1), alachlor+linuron (2), and alachlor+linuron+imazethapyr (3) were investigated in double-cropped soybean grown in two row spacing variants, 38 cm and 76 cm, under conventional tillage (CT) or no-tillage (NT). In trials conducted on a sandy loam soil at Zemun Polje, high weediness had a negative effect of on the yield of double-cropped soybean, especially at the higher row spacing tested and with no-tillage. Regression and correlation data revealed a dependence of weediness in double-cropped soybean on tillage system and herbicide combination, and dependence of soybean yield on tillage system.

Relevance and Methods. The effect of three doses of nitrogen fertilizers (N30, N60, and N90) on the formation of a crop of vetch seeds mixed with spring wheat was studied in a field experiment in sod-podzolic sandy loam soil.Results. In average for the study years, the yield of vetch seeds under the influence of nitrogen fertilizers decreased at the dose of mineral nitrogen 30 kg/ha by 12,7% at a dose of 60 kg/ha by 26,4% at a dose of 90 kg/ha by 36,4%, and grain yield of spring wheat increased, respectively, 1,8; 2,5 and 2,9 times. A significant decrease in the yield of vetch was observed at doses of mineral nitrogen N60 and N90, the yield of wheat grain significantly increased at all doses of mineral nitrogen. Nitrogen fertilizers were most effective in drought conditions, when the symbiotic fixation of air nitrogen in the crop area was weakened. Under conditions of increased moisture, nitrogen fertilizers did not provide an increase in the grain yield of the mixture, but increased the resistance of the crop to lodging, which made the mixture more technologically adapted to harvesting.

Studies on the sulphur requirements of crops have largely been restricted to single crops without considering its residual availability to the following crop. With this objective, a field experiment was carried out to study the direct, residual and cumulative effect of S in a moong-raya rotation on sandy loam soil having 8.2 mg kg −1 soil of 0.15% calcium chloride-extractable S. The treatment consisted of four levels of S (0, 10, 20 and 40 kg ha −1 ) applied as gypsum. A significant increase in the grain yield of moong was observed at and above 20 kg S ha −1 , but the difference between the grain yields at application rates of 20 and 40 kg S ha −1 was found to be non-significant. The direct application of 20 kg S ha −1 resulted in a significant increase in the grain yield of raya. The residual effect emanating from the application of 40 kg S ha −1 to the first crop of moong significantly increased the grain yield of raya. The cumulative application of S at different rates, to both the crops, was not found to be beneficial. It is therefore suggested from this study that the application of 20 kg S ha −1 to each crop or 40 kg S ha −1 to the first crop of moong was sufficient to obtain optimum yields of both the crops in a moong-raya cropping sequence. The critical levels of S in the whole shoot in moong and raya plants were found to be 0.23 and 0.37%, respectively.
