Manufacture of Cotton Seed, Cotton Seed Cakes, and Meal

Objectif : Pour tenter de réduire les effets de ces changements climatiques sur les productions, un apport au sol avant les mises en place des cultures de 12 t/ha de déchets de coton graine ou de compost associé à la moitié de la dose d’engrais minéral recommandée (200 kg/ha de NPK + 50 kg/ha d’urée) a permis d’améliorer l’humidité du sol sans aucun effet sur l’eau utile du sol. L’apport de déchets de coton graine ou de compost a permis aussi d’améliorer le nombre de capsules par plante, le nombre de capsules mûres récoltées, la qualité sanitaire des capsules mûres et surtout le rendement en coton graine. Conclusion : L’apport de 12 tonnes/ha de déchets de coton graine associés à de l’engrais chimique à la dose de 100 kg/ha de NPK et 25 kg/ha d’urée constituent un niveau optimum d’utilisation des déchets de coton graine en coton culture. Mots clés : Déchets de Coton graine, Humidité du sol, Rendement du cotonnier, Côte d’Ivoire. Effect of ginned cotton-seed waste application to the ground on soil moisture and cotton yield in northern Côte d'Ivoire ABSTRACT Objective: In an attempt to reduce the effects of climate change on production, an application to the ground prior to the establishment of 12 t/ha of ginned seed cotton waste associated with half of the recommended mineral fertilizer dose (200 kg/ha of NPK + 50 kg/ha of urea) improved soil moisture without any effect on the soil available water capacity. The supply of seed cotton waste or compost has also improved the number of capsules/plant, the number of mature capsules harvested, the sanitary quality of mature capsules and, above all, the yield in seed cotton. Conclusion: The supply of 12 tons/ha of seed cotton waste associated with chemical fertilizer at the dose of 100 kg/ha of NPK and 25 kg/ha of urea constitutes an optimum level of use of cotton seed waste in cotton farming.

Abstract The efficacy of selected insecticides was evaluated against BW/TBW at the Macon Ridge location of the Northeast Research Station. Cotton seed was planted 12 Jun in plots consisting of 4 rows (40 inch centers) X 50 ft. Treatments were arranged in a RCB design and replicated 4 times. Applications were made with a high clearance sprayer calibrated to deliver 6 gpa through Teejet TX-8 hollow cone nozzles (2/row) at 46 psi. Insecticides were applied on 8, 11, 14, 18 Aug and 11 Sep. Treatments were evaluated by examining 50 flower buds (squares) per plot on 11, 14, 22 Aug for evidence of BW/TBW and boll weevil damage. Data reported for boll weevil represent a mean across all sample dates. The plots were mechanically harvested on 16 Oct to determine seed cotton yields. The test area was irrigated by an overhead sprinkler “as needed” during the season, but not within 48 h of treatment applications. Rainfall did not influence the effects of these treatments. Data were analyzed with ANOVA, and means were separated according to DMRT.

Processing Factors

Cottonseed of three Nigerian commercial varieties of cotton, three locational composite seed cotton and cottonseed meals were investigated with respect to their content of gossypol (free and total), tannins, phytin and phytin phosphorus. Free and total gossypol ranged from 1.14 to 1.34% and 1.21 to 1.59%, respectively in cottonseed kernels, and 0.028 to 0.064% and 0.413 to 0.831%, respectively in cotton seed meals. Varietal and environmental factors appeared to influence the gossypol content of cottonseed while the variability in the meals was due to the effects of conditions under which the seed was processed. Tannins ranged from 26.25 to 38.50 mg/100g in the seed kernels and 3.13 to 6.75 mg/100g in the meals. From all indications varietalIocational and processing factors appeared to influence the tannin content of the seed and meals in a similar manner as they influenced the gossypol content. Phytin and phytin phosphorus did not vary appreciably between or within seed type, neither did processing of seed appear to affect their contents in the meals.

The field experiment was performed at Adaptive Research Farm Karor, Layyah by sowing cotton variety (MNH-886) @ 25 kg ha-1. The experiment was conducted by Randomized Complete Block Design (RCBD) with a factorial arrangement and 3 replications. The fertilizer NPK was applied as per recommendation and standard agronomic practices were given at a proper time. The maximum cotton seed germination (m-2) was 37.00 with soaking the seed in potassium chloride solution. A maximum number of plants m-2 was (32.667) in treatment soaking seed in potassium chloride solution. Whereas a minimum number of plants m-2 were (20.66) in the control treatment. Maximum plant height (cm)was observed in treatment soaking the seed in potassium chloride solution. Whereas minimum plant height was recorded in the control treatment. Maximum monopodial branches were observed in treatment soaking the seed in potassium chloride solution, followed by soaking the seed in water for 12 hours (hydro-priming) which is statically at par with soaking the seed in calcium chloride solution. Whereas a maximum number of sympodial branches were recorded at soaking the seed in potassium chloride solution (23.33). Seed priming of cotton seed with water and salts have no effect on the number of squares, flowers, open bolls plant-1 and boll weight (g). Maximum average yield was (2700.00 kg ha-1) in treatment soaking seed in potassium chloride solution. Whereas minimum seed cotton yield was (2338 kg ha-1) in the control treatment. Maximum seed cotton yield was (901.07kg ha-1) in treatment soaking seed in potassium chloride solution. Whereas minimum seed cotton yield was (773.70kg ha-1) in the control treatment. Maximum seed lint yield was (1797.7 kg ha-1) in treatment soaking the seed in potassium chloride (KCl) solution. Whereas minimum seed cotton yield was (1545.6 kg ha-1) in the control treatment. Maximum seed index was (9.0167gm) in treatment soaking the seed in potassium chloride solution (KCl). Whereas the minimum seed index was (7.6133gm) in the control treatment. Seed priming of cotton seed with water and salts have no effect on the uniformity index (%), UHML fiber length, and micro narie value. Maximum GOT (%) was (46.033%) in soaking seed in potassium chloride solution (KCl). Whereas minimum GOT was (42.863%) in the control treatment.

The One

1. Several authors have previously reported that the sulphuric acid treatment of the cotton seed resulted in: (a) earlier germination, (b) higher percentage of seeds germinating, (c) higher yield of seed cotton per acre, and (d) better and more uniform planting (this paper is not concerned with the disinfecting effect of this process).2. A series of experiments, both in the laboratory and under field conditions have been carried out to determine whether the above statements are in agreement with actual experimental data.3. In so far as the rate of germination is concerned, it was found that: (a) untreated seeds often show a smaller percentage of germination than seeds treated with sulphuric acid for various time-intervals, particularly when tested in the laboratory; (b) cotton seed treated with the reagent for from 5 min. to 2 hr. or even 5 hr. in some cases, does not show any decrease in its germinative value as determined by laboratory tests. In field trials seeds treated for 5 or 12 hr. practically do not germinate at all, whereas the 2 hr. treatment often shows a small decline in germination; (c) an enormous difference in the rate of germination has been revealed between the laboratory determinations on the one hand and the field determinations on the other.

Spray Control

Abstract Plots were replicated four times in a RCB design and were four rows wide (40 inch spacing) X45 ft. Stoneville 474 cotton seed of the same seed lot was planted on a Gigger silt loam soil on 7 May. The seeding rate was 4 seed/row ft. Cotton seed was planted with a John Deere 7300 series planter which was equipped with 10 inch seed cones mounted to replace the seed hoppers. Granular in-furrow treatments were applied with standard granular applicators. In-furrow spray treatments were applied with a CO2 charged spray system through 25015 nozzles (1/row) mounted in front of the press wheels. The spray tips were turned to spray across the furrow and calibrated to deliver 5 gpa finished spray. Control of thrips was assessed by randomly selecting 5 plants per plot on 20, 24, 28, and 31 May and 5 and 9 Jun. Plant samples were processed by using whole plant washing procedures to remove insects. Major pest and/or secondary pest control was initiated in Jun and continued on an “as needed” basis through Aug. Percentage of open bolls was determined by counting all open and unopened bolls within a 3.0 m section of a center row on 18 Sep. Plots were harvested on 26 Sep and 10 Oct. These data were subjected to appropriate calculations to determine percent first harvest. The center two rows were mechanically harvested using a John Deere spindle type picker. Yields were converted to lbs seed cotton/acre.
