The Impact

Crop productivity is limited by several environmental constraints. Among these, micronutrients availability to plants plays a key role in agricultural crops production. Boron is an important micronutrient for crops and it significantly aids in a grain setting. Soil applied boron become unavailable to plant due to fixation in soil sites and cause nutrients deficiency in plants, immature grain settings, and yield reduction. Thus, the aim of this work was to quantify the impact of the foliar application of boron gradients on the yield and growth of barley (Hordeum vulgare L.). Five treatments were studied, which included; T1= Control (0% B), T2 = 0.5% B, T3 = 1% B, T4 =1.5% B, and T5 =2% B. The results indicated that foliar application of B significantly increased the yield and growth traits in barley. However, 2% foliar application of B showed the highest value for all studied traits including; plant height (5.6%), number of tillers per plant (2.4%), spike length (32%), weight gain per spike (6.2%), seed index (6%), grain yield (10%), and biological yield (4%). Based on these findings, it can be concluded that the foliar application of B at 2% can be used to improve the growth and yield in barley.

Investigating the effect of urea and nano-nitrogen fertigation and foliar application of nano B and Mo on growth and yield of potato Solanum tuberosum L. [Rivera-A]. The study was conducted in a private farm located in the Al-Taleah area - Babylon governorate. The experiment consisted of (12) treatments consisting of separated fertigation of nano nitrogen (25% N) and urea (46% N), single treatments of leaf spraying of nano Mo (5%), Nano B (9%), nano-binary combinations (Mo+B) and (U+ Nano Mo), (U+Nano B), Nano (N+Mo), Nano (N+B), and tricombination treatments of (U+Mo+B), Nano (N+Mo+B) additional to the control treatment. Randomize Complete Block Design (RCBD) and one way simple experiment with three replicates. Fertilizers were applied at levels of 40 liters h-1 of Nano-N fertilizer (25% N) and 300 kg h-1 urea fertilizer (46% N). They were sprayed early in the morning after (40) days after planting four times. Two weeks is the period between an application and another according to the recommendation of (1) kg  h-1 nano-fertilizer of (B) and (500) g h-1 of  Mo. Fertilizers were injected and sprayed at (10, 20, 30 and 40)% of the total amount of the fertilizer were applied as the first, second, third and fourth applications, respectively. Some growth traits were tested including the chlorophyll content in the leaves, the total dry vegetative yild, the soft tubers yield, and the biological yield, proteins and ascorbic acid yield compared to the control (spray water only). The results of the Duncan test showed a significant increase in most of the studied traits of nano-tricombination (N+Mo+B) in the fresh tubers yield,  dry vegetative yield  , the biological yield, starch yield ,the total protein and ascorbic yield (37.53, 1.799, 8.138,4.152 , 481.3and 653.8 meg ha-1) respectively .compare to control (21.58 , 0.890, 4.463  ,2.323 , 366.1 and 215.5 meg ha-1) respectively.

Freezing Chamber

Three spring barley (Hordeum vulgare L.) cultivars were planted at four seeding dates to evaluate the effect of a simulated frost at the two-leaf stage on growth and yield. A portable field freezing chamber was used to subject the plants to a − 5.6 °C stress. The frost caused 49, 64 and 68% injury to the leaves and delayed heading by 2.4, 1.4 and 2.4 days in Gait, Atlas and Olli, respectively. Frost also reduced the number of tillers per plant, ripe heads per plant and plants per plot in all cultivars. Although the late-maturing cultivar Galt had the most leaf frost resistance, the average 13.8% yield reduction within all three cultivars, owing to the freezing stress, was not significantly different between any of the cultivars. Complete defoliation by clipping resulted in no further reduction in yield than that which occurred from partial defoliation by freezing. Delayed seeding resulted in an 8.6% reduction in yield. Frost reduced the yield of early seeded cultivars by 9.8% and late-seeded cultivars by 17.1%.

This study was carried out at the experiment field, Kalar Technical Institute, Garmian Region in two growing seasons of 2016-2017 and 2017-2018 in order to evaluate the growth and yield potentials of barley under water stressed using hybrids as a source of wide range of genotypic variations. Therefore, five F2 barley hybrids (Hordeum vulgare L.) were screened for grain yield, biomass dry matter, plant height and harvest index under irrigated and drought conditions. Results showed that there was no effect of drought on grain yield (P>0.05) in 2017, while significantly reduced yield in 2018 and across-year mean (P-2 (3//14) under irrigated condition, and 267.8 (3//5) to 302.3 g m-2 (3//4) under unirrigated condition (P=0.001), biomass dry matter was ranged from 1099.1 (3//1) to 1370.5 g m-2 (3//14) under irrigated condition, and 892.6 (3//1) to 1153.9 g m-2 (3//14) under unirrigated condition (P=0.05), and harvest index were from 25.1 (3//14) to 28.0 (3//1) under irrigated conditions, and 25.9 (3//14) to 31.2 (3//1) under unirrigated conditions (P=0.04). Regression analysis, averaging over years, showed a positive relationship between grain yield and biomass under irrigated (R2=0.76; P=0.05), despite that, any positive relation was not found under unirrigated conditions (R2=0.43; P=0.23) due to post-anthesis drought stress. A strong relationship was also found between plant height and biomass dry matter under both irrigated (R2=0.89; P=0.02) and unirrigated (R2=0.97; P=0.003) conditions due to the high contribution of plant height in increasing plant biomass. It is concluded that genotypes had different response to drought due to their genetic diversity, and relatively low impact of water stress was appeared on growth and grain yield of barley in this semi-arid region compared to worldwide expected range of yield reduction.

This research was made for the comparison of the effects of purple nutsedge allelopathy and other methods on the weed management in barely at Students’ Experimental Farm, Department of Agronomy, Sindh Agriculture University, Tandojam for weed as well as barely parameters having eight treatments with three replications. The data revealed that maximum weed number (45.6 m-2), weed fresh weight (20.6 g m-2), weed dry weight (6.3 g m-2) was observed under T1= No weeding (control). However, the maximum weed control (91.3%) was recorded under T7= Puma super 75 EW at 0.625 L ha-1, 50 reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS). The barley crop results revealed that maximum tillers (355.6 m-2), plant height (106.3 cm), spike length (11.5 cm), grains spike-2 (47.3), seed index (51 g), biological yield (11737 kg ha-1), grain yield (4493 kg ha-1) and harvest index (41.9%) was recorded under T7= Puma super 75 EW at 0.625 L ha-1 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS). Hence, current results manifested that proper application of puma super 75 EW at 0.625 L ha-1 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (50 DAS) produce maximum growth and yield parameters of barley crop. So, it was suggested that application of puma super 75 EW at 0.625 L ha-1, 50 % reduced (30 DAS) + Purple nutsedge water extract at 15 L ha-1 (45 DAS) apply for getting higher yield (4493 kg ha-1) of barley crop. It was finalized that this study will be very fruitful for the future progress of barley production.

Toxic Concentrations

Soil salinity can severely reduce crop growth and yield. Many studies have investigated salinity tolerance mechanisms in cereals using phenotypes that are relatively easy to measure. The majority of these studies measured the accumulation of shoot Na+ and the effect this has on plant growth. However, plant growth is reduced immediately after exposure to NaCl before Na+ accumulates to toxic concentrations in the shoot. In this study, nondestructive and destructive measurements are used to evaluate the responses of 24 predominately Australian barley (Hordeum vulgare L.) lines at 0, 150 and 250 mM NaCl. Considerable variation for shoot tolerance mechanisms not related to ion toxicity (shoot ion-independent tolerance) was found, with some lines being able to maintain substantial growth rates under salt stress, whereas others stopped growing. Hordeum vulgare spp. spontaneum accessions and barley landraces predominantly had the best shoot ion independent tolerance, although two commercial cultivars, Fathom and Skiff, also had high tolerance. The tolerance of cv. Fathom may be caused by a recent introgression from H. vulgare L. spp. spontaneum. This study shows that the most salt-tolerant barley lines are those that contain both shoot ion-independent tolerance and the ability to exclude Na+ from the shoot (and thus maintain high K+ : Na+ ratios).

The Impact

The research work was carried out to investigate the efficacy of different mother culture media viz., rice straw (T-1), rice straw and rice bran (T-2), rice husk (T-3), rice grain (T-4), maize grain (T-5), and rice straw and wheat bran (T-6) and the impact of age of mother culture and substrate sterilization techniques viz., sun dried for 8 hrs covering with transparent polythene (A-1), black polythene (A-2), blue polythene (A-3) sheet, autoclave for two hrs at 121°C (A-4), and hot water for one hr (A-5) for the commercial cultivation of Volvariella volvacea (Bull.) Singer. The maximum mycelium run rate and minimum days required for completing the mother culture were recorded in T-4. The lowest days required for primordial initiation (DRFPI) was 6 in T-1 and T-2, whereas highest DRFPI was recorded in T-3. The maximum (13.33) days required for first harvest (DRFFH) and lowest (109) number of effective fruiting bodies (NEFB) were recorded in T-3. The minimum (10.67 days) DRFFH was found in T-2 and maximum (239.30) NEFB was recorded in T-1. The lowest length and diameter (LFB and DFB) were recorded in T-5 (3.03 cm) and T-1 (1.66 cm), while highest LFB and DFB were observed in T-3 (3.20 and 2.39 cm). Maximum biological yield and efficiency were observed in rice straw and wheat bran materials. The highest NEFB, DFB, biological yield and efficiency were recorded in 30 days old of mother culture. The results revealed that combined rice straw and wheat bran were the excellent mother culture medium and 30 days old was the best age for the commercial production of paddy straw mushroom. Considering the experimental results on the sterilization techniques it may be suggested that hot water sterilization of rice straw substrate was the best sterilization technique for the commercial production and yield improvement of V. volvacea.
