            1

Objectives of the present study are to determine the variations in forage yield and quality of soybean cultivars. Experiments were conducted in randomized complete blocks design with 3 replications during the growing season of 2016. A total of 10 cultivars were used as the plant material of the experiments (Bravo, A3127, Traksoy, İlksoy, Mersoy, Nova, SA-88, Arısoy, Safir, Atakişi). Cultivars had a significant effect on yield and chemical composition. Results revealed that green herbage yields varied between 826.39 - 1199.17 kg/da, dry hay yields between 247.71 - 357.90 kg/da, crude protein yields between 16.91 - 39.86 kg/da, acid detergent fiber (ADF) ratios between 26.56 - 34.61%, neutral detergent fiber (NDF) ratios between 38.43 - 44.85%, crude ash contents between 7.20 - 11.22%, crude protein contents between 6.66 - 13.53%, dry matter digestibility (DDM) values between 61.94 - 68.21%, dry matter intake (DMI) values between 2.68 - 3.12% and relative feed values (RFV) between 2.68 - 3.12. The results of the study showed that A3127 cultivar was found to be prominent with green herbage yield (1199.17 kg/da) and dry hay yield (357.90 kg/da) and Safir cultivar was found to be prominent with crude protein yield (39.86 kg/da). It was concluded that the soybean cultivars A3127 and Safir could be recommended for hay production.

Karamanos, R. E., Flore, N. A., Harapiak, J. T. and Stevenson, F. C. 2012. The effect of non-targeted application of propiconazole on the yield and quality of malt barley. Can. J. Plant Sci. 92: 341–349. There is a desire to use non-targeted applications of foliar fungicide to improve malting barley production under higher fertility situations. An experiment was conducted at 80 sites (location by year combinations) with a 12 combinations of N/P/K rate-placement to determine if applications of propiconazole improve malt barley yield and quality under high fertility conditions. Treatment differences for days to maturity were no greater than about 1 d. Fungicide by fertility treatment interactions were not significant (P>0.05). Applications of propiconazole improved yield by 305 kg ha−1 (6%) and plump kernels by 3 g kg−1 (3%) across all fertility treatments, which included N fertilizer rates ranging from 0 to 90 kg N ha−1. The effect of fungicide on yield was greatest at sites with highest yield potentials (ca. 8000 kg ha−1) and was not statistically significant at lower-yielding sites (ca. 3000 kg ha−1). Application of propiconazole also improved net returns [barley revenue – (N cost+propiconazole cost+other operating costs)] by $22 ha−1 with higher barley priced ($190 T−1) and high yield potentials. At sites with low yield potential, the application of propiconazole resulted in net losses of about $7 ha−1 compared with not applying propiconazole. Nitrogen fertilizer rates from 0 to 90 kg N ha−1 (15/30-0 P-K fertilizer treatment combinations) increased yield and protein concentration, and reduced plump kernels in a curvilinear fashion when averaged across fungicide treatments. Net returns were maximized at N fertilizer rates slightly less than 90 kg N ha−1, depending on the price/cost regime. Consequently, malt barley producers will have to consider tradeoffs regarding N fertilizer rate that optimizes yield/returns and kernel quality. Also, decisions regarding fungicide applications and N/P/K fertilizer rate-placement applications can be made independent of each other for malt barley production.

Onion Cultivar

An experiment was conducted on a San Anton (Cumulic Hasplustolls) fine loamy mixed isohyperthermic in the southern irrigated coastal plain of Puerto Rico, to evaluate the influence of various N-P-K levels on yield and quality of onion (cultivar Texas Grano 502). All P and K fertilizer were broadcast and mixed with the soil at planting. Half of the N fertilizer was broadcast at planting and half was banded 6 weeks later between rows and left uncovered. Mean yield differences attributable to fertilizer levels were not significant. The soil seems to have sufficient available native N to meet this crop's needs. This may be in part attributable to continuous fertilizer applications over the years for sugarcane production in this soil. An average onion production of 22 metric tons/ha was obtained. The world average production is 11 metric tons/ha. Based on the results obtained, the production of onions in th is soil is recommended for two reasons: 1) The high tonnage that can be obtained, and 2) the low investment on fertilizers if planted on soils of high fertility, especially if previously used for sugarcane and fertilized over a long period.
