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.

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. Keywords: Seed Cotton Waste, Soil Moisture, Cotton Yield, Ivory Coast.

Abstract The effectiveness of the classic screening strategy was verified, by duplicating and verifying the degradation of gossypol by the Aspergillus niger. It can reduce the free gossypol content through biosorption but has no effect on the total gossypol content and cannot effectively degrade gossypol. And the most interesting thing we found the strain can secrete agarase, utilise agar as carbon source. In this case, that will mislead researchers and lead them to make wrong judgments. That turns out the usual methods of previous screening strategies are not rigorous enough, the classic screening method has defect in screening toxin-degrading strain, so agar control group should be added. In this study, some suggestions are put forward to optimise the same type of experiments and broaden the idea of detoxification by microorganisms and provide reference for screening effective toxin-degrading microorganisms.

Fermentation is one of the most important bioprocessing techniques used to enhance nutritional components and a reduction in anti-nutritional compounds. In the present work, germinated and ungerminated grains of white and red –brown finger millet landraces were subjected to 8, 16 and 24 hours of fermentation to find out its response in terms of nutritional, anti-nutritional compounds and antioxidant activity. White and red-brown grains showed significant response to 16 and 24 hours process in terms of nutritional and anti-nutritional changes. Significant reduction in the tannin content (73%) was noted for germinated and un-germinated grains with the enhancement in nutritional compounds. Highest antioxidant activity was noted for germinated (91%) grains of white seed coat color grains. Process of natural fermentation and the microflora produces various endogenous enzymes which causes enhancement and reduction of nutritional and antinutritional compounds. Obtained results prove the importance of fermentation process and conservation of landraces for nutritional security.

A large number of flower buds, flowers and premature bolls of cotton are shed without contributing to seed-cotton yield. Abscission may be affected by environmental factors. It may, therefore, be possible to reduce it by modifying the micro-environment within the crop canopy.

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.

Use of cottonseed as protein source for food application and monogastric animals are restricted due to the presence of polyphenolic toxic content known as gossypol. Reduction of gossypol and improving crude protein content in cottonseed flour may increase its utility for feed and food industries. The present study aims to analyze the influence of three individual methods viz., sprouting method, enzymatic method and solvents method on free and total gossypol content, crude protein content, oil content and flour yield. Enzymatic treatments were performed using culture candida tropicalis, saccharomyces cerevisiae and combinations of both whereas for solvent treatments four different solvents namely acetone, ethanol, methanol and iso-propanol with their four different levels (70-100%) were applied. Results of this study revealed that 70% aqueous acetone showed maximum free gossypol reduction (97%), crude protein content (65.6%), oil content 31.3 % and 57% flour yield was observed. However, total gossypol reduction was only 51%. Other side, enzymatic treatment based on candida tropicalis found more effective in terms of total gossypol reduction (73%), however crude protein content was recorded only 39.4%.

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.
