Weed Emergence

AbstractWith the recent confirmation of protoporphyrinogen oxidase (PPO)-resistant Palmer amaranth in the US South, concern is increasing about the sustainability of weed management in cotton production systems. Cover crops can help to alleviate this problem, as they can suppress weed emergence via allelochemicals and/or a physical residue barrier. Field experiments were conducted in 2014 and 2015 at the Arkansas Agricultural Research and Extension Center to evaluate various cover crops for suppressing weed emergence and protecting cotton yield. In both years, cereal rye and wheat had the highest biomass production, whereas the amount of biomass present in spring did not differ among the remaining cover crops. All cover crops initially diminished Palmer amaranth emergence. However, cereal rye provided the greatest suppression, with 83% less emergence than in no cover crop plots. Physical suppression of Palmer amaranth and other weeds with cereal residues is probably the greatest contributor to reducing weed emergence. Seed cotton yield in the legume and rapeseed cover crop plots were similar when compared with the no cover crop treatment. The seed cotton yield collected from cereal cover crop plots was lower than from other treatments due to decreased cotton stand.

High Yielding Varieties

Thirty six candidate cotton varieties developed by different breeders of Pakistan were tested consecutively for two years (2017 and 2018) and at seven locations of Sindh and Balochista Provinces in national coordinated varietal trials (NCVT).  The trials were conducted to explore seed cotton yield potential and fiber properties against two check varieties (CIM-602 and FH-142/IUB-13).  As per claim of the breeders, the samples of all varieties for both the years were sent to four designated biotechnological laboratories for conducting biochemical tests also. The results revealed highly significant differences among the varieties for both the years. During the year 2017, on an average of six location, top ten high yielding varieties recorded were GH-Haadi, Weal-AG-6, VH-189, GH-Mubarak, Weal-AG-5, MNH-1026, Badar-1(DG), FH-444, CIM-343 and TJ-Max(DG) which yielded 3434, 3407, 3342, 3255, 3251, 3248, 3185, 3154, 3134 and 3131 kg/ha seed cotton yield respectively. When the results of 2018 trial were looked at, averagely top ten high yielding varieties were GH-Haadi, ICI-2121, CRIS-613, VH-383, VH-189, NIAB-898, FH-490, Cyto-225, Tahafuz-10(DG) and GS-Ali-7 with 3526, 3356, 3306, 3139, 3101, 3091, 3084, 3074, 3060 and 3026 kg/ha of seed cotton yield respectively. However, on an average of both the years (2017 and 2018), top ten high yielding varieties were GH-Haadi, VH-189, CRIS-613, Weal-AG-6, GH-Mubarak, Badar-1(DG), ICI-2121, Weal-AG-5, FH-940 and MNH-1026 producing 3480, 3221, 3186, 3155, 3113, 3083, 3057, 3054, 3042 and 3042 kg/ha of seed cotton respectively. As regards fiber properties, (04 candidate varieties) could qualified all fiber standards set by government. The biochemical test results received from all four laboratories revealed that on an average of four laboratories and two years, the trait purity range recorded was from 42 to 96 percent, whereas, quantification of Bt toxin ranged from 0.74 to 2.62. From the present study, it was concluded that almost 15-20 candidate varieties have the potential to be included among already approved varieties for commercial cultivation in the province of the Punjab.

Abstract. Cover crops have been recognized as a vital part of conservation agriculture, but they need to be managed appropriately to avoid planting problems related to the large amounts of biomass. Typically, cover crops are rolled in the same direction as the travel direction of the planter, but producers have been inquiring if other rolling directions are also effective. To answer this question, replicated field experiments (split-plot design) were conducted at two locations in Alabama during three growing seasons to evaluate different rolling directions of a cereal rye cover crop, i.e., non-rolled (standing rye), 0° (cotton planting direction), 180° (opposite of planting direction), 15° (offset from 0°), and 195° (15° offset from 180°), using a roller/crimper. A no-till cotton planter with different row cleaners, i.e., a commercially available row cleaner (Dawn with coulter), a residue pusher with and without a coulter, and no row cleaner (control), was used to determine the effects of rolling direction and row cleaners on cotton population, emergence rate, and yield. The rye cover crop was terminated with a roller/crimper and glyphosate. Among growing seasons, significant differences existed in rye production, cotton population, emergence rate index (ERI), seed cotton yield, amount of residue accumulated on the planter, and the time required to remove residue from the planter. For the rolling direction treatments, higher cotton population was found for 0° and non-rolled rye, and the lowest population was found with 195°. The ERI was higher for 0° and non-rolled rye, and the lowest ERI was observed for 195°. For the row cleaner treatments, the cotton population and ERI were both higher for Dawn with coulter and pusher with coulter. Across three growing seasons, cotton yield was not affected by rolling direction but was affected by row cleaner. Significantly higher cotton yield was associated with Dawn with coulter and pusher with or without coulter, compared to lower yield for no row cleaner. The important findings were that residue accumulation was not problematic when the cover crop was rolled. When the cover crop was not rolled, the pusher accumulated more residue than Dawn with coulter; however, the time required to remove the residue was more than 3 times higher for Dawn with coulter as compared to the pusher. The data indicated that, across all growing seasons and locations, rolling direction and row cleaner affected the cotton population, ERI, residue accumulation on the planter, and the time required to remove residue. In contrast, rolling direction did not affect seed cotton yield, but row cleaner had an effect on seed cotton yield. Based on the results, the best combination of rolling direction and row cleaner was 15° offset to the cotton planting direction and Dawn with coulter, which resulted in higher cotton population, ERI, and seed cotton yield without residue accumulation on the row cleaner. However, the 0° and 180° Dawn with coulter and 15° pusher with coulter combinations were also effective in producing relatively higher cotton population, ERI, and seed cotton yield.

Abstract. Cotton breeding in Bulgaria is mainly aimed at improving the earliness, productivity and fiber quality of modern varieties. The creation of new genetic diversity is one of the basic prerequisites for the success of breeding programs. The aim of the study was to evaluate cotton lines obtained by intraspecific and remote hybridization combined with backcross technology, with a view to their most effective usage in selection. Twenty-three lines were included in competitive variety trials conducted during the 2014-2017 period. The averaged results showed that lines 550, 639, 641, obtained by remote hybridization, appeared to be very promising. These three lines were distinguished by the best combination of productivity, fiber length and fiber lint percentage, and by these three indicators they exceeded the standard variety Chirpan-539. A new cotton variety Aida (No. 457) was approved, which in seed cotton yield and fiber yield, and technological fiber properties surpassed the standard varieties Chirpan-539 for earliness and productivity and Avangard-264 for fiber quality. The candidate variety 535 continued the state variety testing. Two new candidate cotton varieties No. 550 and No. 553 were released. In the state variety testing the three candidate varieties confirmed their qualities. The obtained lines, distinguished by one trait or by a complex of qualities, enriched the gene pool of Bulgarian cotton.
