The aim of this study was to reduce the lodging and improve grain yield by evaluation the performance of some oat cultivars introduced into Iraq. A field experiment was conducted during two seasons of 2017-2018 and 2018-2019, included four cultivars (Genzania, Shafa, Carrolup and Hamel) under the influence of foliar spraying of ethephon at concentrations of 0, 500 and 1000 ppm, and foliar application of boron with concentrations of 0, 50 and 100 ppm. Using RCBD within split–split arrangement and three replicates. The results were revealed that Genzania was recorded the highest number of grains head-1 and grain yield 6.512 and 5.565 t ha-1 in the two seasons respectively. Shafa had the highest number of active tillers m-2 in both seasons and the highest single grain weight in the second season. Carrolup was produced the highest single grain weight in the first season. Spraying ethephon with concentrations of 500 and 1000 ppm increased stem diameter and number of active tillers m-2 for both seasons. Spraying 500 ppm of ethephon increased grain yield in the first season and reduced lodging rate in the second season. Ethephon with 1000 ppm reduced lodging rate in both seasons. Foliar application of boron with concentrations of 50 and 100 ppm increased plant height and grain yield in both seasons.

One of the main problems faced in corn cultivation, especially in Cerrado regions, is the deficiency of micronutrients. Among the micronutrients essential for the development of plants, boron (B) stands out for participating in a series of physiological processes. Based on this, the present work aimed to evaluate the performance of corn under fertilization with different sources and doses of boron. The randomized block design in a 4x3 factorial scheme was used. Four boron doses (0, 1, 2, and 3 kg ha-1) and three nutrient sources (boric acid, borax, and ulexite), applied in topdressing, were evaluated. Plant height (cm), stem diameter (mm), first ear insertion height (m), ear length (cm), ear diameter (mm), number of rows per ear, number of grains per row, 1000-grain weight (g), and grain yield (kg ha-1) were evaluated. It was concluded that the boron sources and doses used did not influence the results of plant height, first ear insertion height, number of rows per ear, and grain yield. The three doses evaluated provided increases in stem diameter, with a dose of 2.08 kg ha-1 being the one with the highest average. The application of borax and ulexite results in higher values of ear diameter, number of grains per row, and 1000-grain weight. The dose of 1.74 kg ha-1 of boron provides the highest 1000-grain weight.

An experiment to investigate the effect of seed rate (5, 7.5, 10, 12.5 and 15 kg ha-1) and row spacing (30, 45 and 60cm) on agronomic characteristics of plants including stem densitym-2, plant height, stem diameter, number of heads m-2, number of heads per plant, number of grains per head, 1000-grain weight and grain yield was conducted using the cultivar “Sorghum 2011” for two years 2016 and 2017. Seed rates and row spacing had significant effect on plant height, plant density m-2, number of heads m-2, number of grains per head and grain yield. Row spacing had non-significant effect on stem diameter, number of heads per plant and 1000-grain weight. Row spacing at 30 cm produced the highest number of plants m-2 and plant height. Plant height increased with increase in seed rate in all the row spacing. Stem diameter decreased with increase in the seed rate and row spacing. Narrow row spacing (30 cm) and low seeding rate (5 kg ha-1) produced the maximum grain yield consistently during both years. Lower yields were recorded in the treatments having greater row spacing (60 cm) and higher seed rates (7.5, 10, 12.5 & 15 kg ha-1). Higher seed rates and wider row spacing induced morphological changes rendering plants to lodging.SAARC J. Agri., 15(2): 81-91 (2017)

Beans are one of the most important crops in Brazil but still have a low yield. The use of technologies such as the application of biostimulants can provide greater yield for the crop. Thus, the work aimed to evaluate the effect of using Azospirillum brasilense and phytohormones on Jalo Precoce beans. The experiment was carried out in randomized blocks with nine treatments and four replications. The treatments consisted of a control, Stimulate (compound of phytohormones), and A. brasilense applied isolated or associated to the seeds or in a furrow. The plant height, stem diameter, shoot dry matter, number of pods per plant, number of grains per pod, the weight of grains per pod, and 100-grain weight were favored by A. brasilense and compound of phytohormones. The highest yield of Jalo Precoce beans (2218 kg ha-1) was obtained using the A. brasilense + phytohormone compound applied in the sowing furrow. The grain yield of Jalo Precoce beans showed a high positive correlation with the number of pods per plant and medium correlation with stem diameter and shoot dry matter.

Triticale is mainly grown for feed grain and biomass production for thatching straw and general human use. A combined analysis with a factorial layout in the two years of 2016 and 2017 with five replications was used to evaluate the yield and yield components of triticale under different methanol concentrations and irrigation managements in Isfahan, Iran. Irrigation treatments consisted of irrigation on the basis of 70%, 80%, 90% and 100% crop water requirements, and methanol treatments as foliar application on the basis of 15% methanol concentration, 30% methanol concentration and control treatment (0%). Methanol application influence on one hundred grain weight was significant. The maximum plant height, number of tillers, Leaf area index (LAI), leaf area duration (LAD), one hundred grain weight, grain yield, biological yield, harvest index and protein content were achieved in irrigation on the basis of 100% crop water requirement. The maximum plant height, number of tillers, LAI, LAD, one hundred grain weight, grain yield, biological yield, harvest index and protein were obtained in 2017. Foliar methanol application with 15% concentration obtained the maximum plant height, LAI, LAD, one hundred grain weight, biological yield, soil plant analytical development (SPAD) and protein percentage. The results of this experiment suggest that methanol can aid in alleviating the effects of drought stress on triticale in the climatic condition of Isfahan. It is concluded that triticale cultivars performed better in 2017, with 15% concentration of methanol application and irrigation on the basis of 100% crop water requirement.

Nitrogen fertilization associated to the application of molybdenum (Mo) can increase grain yield in maize crops. Therefore, the objective of this study was to evaluate the effect of molybdenum application forms associated to topdressing nitrogen fertilization on production components and maize crops grain yield. The experiment was conducted with the cultivar Pioneer® 30F53H, under a randomized blocks experimental design, with subdivided parcels and four replications. Four forms of Mo applications were evaluated in each parcel: control (without Mo); seeds treatment (40 g ha-1 Mo); foliar treatment (40 g ha-1 Mo); seeds treatment (20 g ha-1 Mo) plus foliar treatment (20 g ha-1 Mo), using potassium molybdate as Mo source. The sub-parcels received four dosages of nitrogen (N), in topdressing (0, 80, 160 and 240 kg ha-1 N), in the form of urea. The experiment evaluated plant height, ear insertion height, stem diameter, number of grains per ear, 100 grains mass and grain yield in maize crops. The increase in N dosages in topdressing increases plant height, ear insertion height, stem diameter, number of grains per ear, 100 grains mass and maize crop grains yield. The application of molybdenum improves N absorption by maize crops. When applied via seeds treatment, Mo brings better results to foliar application in partial or total dosages.

The efficiency of nitrogen fertilizer applications such as urea is reduced as a function of volatilization and leaching losses. For this reason, the producers have opted for the use of polymerized urea. Therefore, the objective of this work was to evaluate the production components in maize culture as a function of doses of polymerized urea. The experimental design was a 5 × 3 factorial, totaling fifteen treatments, corresponding to five doses Polyblen® 39% N of polymerized urea (0, 250, 500, 750 and 1000 kg ha-1) and three cultivars of maize (30A37, MG580 and MG600). The variables were analyzed after harvest, being: plant height, ear height commercial, stem diameter, leaf area, plant leaf area, ear diameter without husks, ear diameter with husks, ear length without husks, ear length with husks, number of grains per row, number of grains per ear, grain yield, number of rows per ear, 100-grain weight. Regarding the production components in the corn crop, the presence of Polyblen® polymerized urea influenced all variables analyzed. While varieties 30A37, MG580 and MG600 demonstrated a significant increase in their productivity averages.

A study on genetic variability, heritability and genetic advance for seed yield and component traits was made in 40 genotypes of riceduring kharif 2011-2012 at SHIATS, Allahabad. The analysis of variance showed highly significant differences among the treatments for all the 13 traits under study.The genotypes namely CN 1446-5-8-17-1-MLD4 and CR 2706 recorded highest mean performance for panicles per hill and grain yield. The highest genotypic and phenotypic variances (VG and VP) were recorded for spikelets per panicle (3595.78 and 3642.41) followed by biological yield (355.72 and 360.62) and plant height (231.48 and 234.35).High heritability (broad sense) coupled with high genetic advance was observed for plant height, flag leaf length, panicles per hill, tillers per hill, days to maturity, spikelet’s per panicle, biological yield, harvest index, 1000 grain weight and grain yield, indicating that selection will be effective based on these traits because they were under the influence of additive and additive x additive type of gene action. Highest coefficient of variation (PCV and GCV) was recorded for tillers per hill (18.42% and 17.23%), panicle per hill (19.76 % and 18.68%), spikelet’s per panicle (34.30 and34.07 %), biological yield (28.31 % and 28.12 %), 1000 grain weight (15.57 % and 15 31 %) and grain yield (46.66% and 23.54 %), indicating that these traits are under the major influence of genetic control, therefore the above mentioned traits contributed maximum to higher grain yield compared to other traits, indicating grain yield improvement through the associated traits.

The research was conducted at Research Area of Department of Agronomy, Bahauddin Zakariya University Multan, during the spring season, 2016. The study aimed to evaluate the influence of foliage applied zinc on growth, yield and oil contents of hybrid sunflower. Experimental treatments comprise of two sunflower hybrids viz. H1= Hysun-33 and H2= S-278 and three zinc levels viz. T1= Control (no application), T2=1% ZnSO4 and T3 = 2% ZnSO4. The experiment was laid out in Randomized Complete Block Design (RCBD) with split plot arrangement and repeated thrice. Data regarding growth, yield and oil contents were collected by using standard procedures. Results revealed that sunflower hybrid Hysun-33 gained maximum plant height (210.67cm), stem diameter (2.427), head diameter (15.533) achene number (852), achene yield (189.19 t ha-1), leaf area (789.56cm2) and oil contents (40.423%) followed by sunflower hybrid S-278. Zinc application significantly improved the yield and oil contents. In this regard, maximum plant height (194.67 cm), stem diameter (2.718cm), head diameter (14.633 cm), achene number (842.17), achene yield (194.56 t ha-1), leaf area (782.5cm2) and oil contents (40.12%) from 2% foliar application of zinc followed by 1% foliar application of zinc. Whereas, minimum plant height, stem diameter, head diameter, achene number, achene yield, leaf area and oil contents were recorded from control where no zinc was applied. Interaction of sunflower hybrids with zinc was also significant. In this contest, maximum plant height (231.67cm), stem diameter (2.917cm), head diameter (15.7cm), achene number (925.0), achene yield (205.89 t ha-1), leaf area (801.33cm2) and oil contents (41.65%) were recorded from sunflower hybrid Hysun-33 with 2% application of zinc followed by sunflower hybrid S-278 with 1% zinc foliar application. In Conclusion, sunflower hybrid along with the 2% foliar application of zinc is the most suitable combination to achieve higher yield and oil contents.
