The regional agroecological conditions, specific to the Transylvanian Plain, are favorable to soybean crops, but microclimate changes related to global warming have imposed the need for agrotechnical adaptive measures in order to maintain the level of soybean yield. In this study, we consider the effect of two soil tillage systems, the seeding rate, as well as the fertilizer dosage and time of application on the yield and quality of soybean crops. A multifactorial experiment was carried out through the A × B × C × D − R: 3 × 2 × 3 × 3 − 2 formula, where A represents the year (a1, 2017; a2, 2018; and a3, 2019); B represents the soil tillage system (b1, conventional tillage with mouldboard plough; b2, reduced tillage with chisel cultivator); C represents the fertilizer variants (c1, unfertilized; c2, one single rate of fertilization: 40 kg ha−1 of nitrogen + 40 kg ha−1 of phosphorus; and c3, two rates of fertilization: 40 kg ha−1 of nitrogen + 40 kg ha−1 of phosphorus (at sowing) + 46 kg ha−1 of nitrogen at V3 stage); D represents the seeding rate (1 = 45 germinating grains (gg) m−2; d2 = 55 gg m−2; and d3 = 65 gg m−2); and R represents the replicates (r1 = the first and r2 = the second). Tillage had no effect, the climate specific of the years and fertilization affected the yield and the quality parameters. Regarding the soybean yield, it reacted favorably to a higher seeding rate (55–65 gg m−2) and two rates of fertilization. The qualitative characteristics of soybeans are affected by the fertilization rates applied to the crop, which influence the protein and fiber content in the soybean grains. Higher values of protein content were recorded with a reduced tillage system, i.e., 38.90 g kg−1 DM in the variant with one single rate of fertilization at a seeding rate of 45 gg per m−2 and 38.72 g kg−1 DM in the variant with two fertilizations at a seeding rate of 65 gg m−2.

Crop Biomass

Adoption of cover crop interseeding in the northwestern Corn Belt in the USA is limited due to inadequate fall moisture for establishment, short growing season, additional costs, and need for adapted winter-hardy species. This study evaluated three cover crop treatments—no cover crop, winter rye (Secale cereale L.), and winter camelina (Camelina sativa (L.) Crantz)—which were interseeded at the R6 soybean growth stage, using two different soybean (Glycine max (L.) Merr.) maturity groups (0.5 vs. 0.9) and two row spacings (30.5 vs. 61 cm). The objective was to evaluate these treatments on cover crop biomass, soil cover, plant density, and soybean yield. Spring wheat (Triticum aestivum L.) grain yield was also measured the following year. The early-maturing soybean cultivar (0.5 maturity) resulted in increased cover crop biomass and soil cover, with winter rye outperforming winter camelina. However, the early-maturing soybean yielded 2308 kg·ha−1, significantly less compared with the later maturing cultivar (2445 kg·ha−1). Narrow row spacing had higher soybean yield, but row spacing did not affect cover crop growth. Spring wheat should not follow winter rye if rye is terminated right before seeding the wheat. However, wheat planted after winter camelina was no different than when no cover crop was interseeded in soybean. Interseeding cover crops into established soybean is possible, however, cover crop biomass accumulation and soil cover are limited.

Irrigation Requirements

Four experiments were conducted at two locations in southern Alberta, where no indigenous Rhizobium japonicum existed, to determine the effects of seeding dates, fertilizers, irrigation, and method of inoculant placement on the yield and quality of several early-maturing soybean (Glycine max (L.) Merrill) cultivars. Highest yields were obtained when soybeans were seeded during the first half of May. Irrigation requirements varied between years but yields were similar whether soil moisture was depleted to the 6 × 104-Pa or the 3 × 104-Pa level before irrigating to field capacity. Soybean yields increased substantially from N fertilizer when the inoculant was applied to the seed without a sticker. When granular inoculant was banded with the seed there was no response to N, and the yields of inoculated plants were higher than those of plants that were uninoculated and received up to 160 kg N/ha. When properly inoculated, early-maturing cultivars such as King Grain strain X005 and Maple Presto were capable of maturing and producing seed of acceptable yield and quality in southern Alberta.Key words: Cultivars, fertilizer, irrigation, inoculant, Glycine max (L.)

Eleven early maturing sugarcane clones were planted in Randomized Block Design for this study. The objective of this study was to investigate the relationships among the yield and quality parameters with cane yield and sugar yield in sugarcane, in order to provide information to help breeders in adopting traits for developing high yield and quality varieties. The analysis of variance revealed significant differences among genotypes for eleven yield and quality characters. Highest cane yield (176.66 t/ha) was recorded in clone 2015R10 and highest Commercial Cane Sugar (CCS) % (14.16) were observed in Co C 671. Correlation coefficient results indicated that cane yield was positively correlated with germination (0.166), number of millable canes (0.210), cane length (0.650), cane girth (0.610), single cane weight (0.880), CCS yield (0.518) whereas Brix% (-0.838), Sucrose% (-0.821), Purity % (-0.720) and CCS % (-0.812) showed negative correlation with cane yield. Sugar yield per hectare is positively correlated with purity% (0.187), cane length (0.413), cane girth (0.503), single cane weight (0.515) and cane yield (0.518). Results indicate that the genotypes should be selected on the basis of cane length, cane girth and single cane weight for getting higher sugarcane yield.
