Opis:: Intercropped systems have agro-ecological and socioeconomic advantages over monocultures. Cotton is used in systems associated with food crops as an option to increase sustainability in family farming. The objective of this research was to evaluate the productivity of cotton in association with food crops, without using any nutritional assistance in the soil. This study was conducted on the rainy season of 2020 in Manabí-Ecuador. Six treatments were performed: four treatments related with the association of cotton with peanut, cowpea bean, field corn, and sweet corn; and two treatments with cotton monoculture (with and without soil fertilization). Agronomic, productive, and phytosanitary variables were evaluated in 60 m2 experimental plots. A randomized complete block design with four replications was used. The results determined that cotton yield in the association with peanut was significantly equal to the monoculture with and without fertilization. In the intercropped food crops, there was a reduction in production in relation to the monocultures. However, it was the peanut in association with cotton with the lowest reduction, in addition to presenting the best Land Equivalence Ratio (1.71) and the best Marginal Rate of Return (120.56%), which suggests that this association is a viable alternative and easy to adopt by the small cotton producer.

Opis:: Size of the cells in developing seed is one of the major factors that regulate yield potentials. Seed of three cotton genotypes, Gossypium hirsutum. L cv (H-4; H-8) G. herbaceum L. cv (G. Cot-15) exhibits variation in their final seed size (large, middle and smaller) were studied for growth and changes in cell wall components during entire period of seed development. High and low molecular weight xyloglucan contents were extracted with 1M and 4M alkali, respectively. Initially the high and low molecular weight xyloglucan contents remained low and increased when cell size stabilized. Changes in esterified and non-esterified pectic substances were also fractionated from the cell wall of developing seed and theirs role in cell elongation phase is discussed. It was observed that bigger seed has higher xyloglucan contents than that of middle and smaller sized seed. Pectic substances were higher during elongation phase in all genotypes. The role of these polysaccharides in sink size development is discussed.

Opis:: Six experiments were conducted for the enhancement in seed cotton yield by increasing water use efficiency and water savings in case of different planting methods of cotton (Gossypium hirsutum L.) crop during the years 2014 & 2015, at three different locations in cotton zone of Punjab (Pakistan) province. The planting methods were, flat planting and no earthing up, flat planting and earthing up after 1st irrigation, flat planting and alternate row earthing after 1st irrigation, flat planting in 112.5/37.5 cm apart paired rows and earthing up after 1st irrigation, ridge planting and bed planting. Cotton crop obtained a maximum benefit from the available water at all three locations in case of flat planting with alternate row earthing up (P3) by predicting a maximum water use efficiency up to 6.79 kg ha-1 mm-1and maximum seed cotton yield of 3432.50 kg ha-1. Maximum water savings of 25.60% was recorded in the same method (P3) during the year 2014, while minimum (-0.17%) was observed in ridge planting (P5) at location number 1 in the same year.

Opis:: Genetically modified Bt cotton (Gossypium hirsutum) leaves with typical symptoms of Alternaria early blight disease resembling that of tomato and potato were observed in the main cotton growing schemes in Sudan. Symptoms on leaves appeared as either brown 2leaf spot with gray centers or leaf blight with concentric rings. Pathogenicity tests using isolates with both symptoms showed that the isolated fungi were highly pathogenic to both G. hirsutum and G. barbadense cotton varieties. Alternaria alternata isolated from infected tomato and potato leaves with early blight symptoms was included for comparison. Microscopic examination showed that the mean length of conidia from cotton, tomato and potato isolates ranged from 26.25 to 45.45 µm, while the width ranged from 9.56 to 13.64 µm. The mean number of transverse septa among all isolates was 3.4 to 5.7 and the peak length ranged from 3.75 to 7.8 µm. Based on morphological characteristics the two isolates from cotton were identified as A. alternata. Genomic DNA was extracted directly from fungal cultures grown on potato dextrose agar (PDA) plates using a Zymo Research Quick DNA kit. A species-specific primer using the internal transcribed spacer ribosomal DNA (ITS rDNA) PCR scoring indicated the presence of A. alternata using primer pair ITS4/ITS5. Amplifications of the internal transcribed spacer region of 600 bp revealed 100% identity of the isolated fungus from cotton with A. alternata from tomato and potato. These data oblige us to reconsider the presence of A. alternata in the four main cotton growing schemes in Sudan while these symptoms have always been described for tomato and potato early blight disease.

Opis:: The cotton leafhopper (Amrasca biguttula biguttula Ishida) is considered to be an alarming insect pest causing both quantitative and qualitative loss in cotton. In situ bioassay studies were done and the role of detoxifying enzymes in conferring resistance to neonicotinoid groups of insecticides in low (MUD), medium (DVG), high (HVR) and very high (GLB) pesticide usage areas of Karnataka were determined. Bioassay studies showed that imidacloprid, thiamethoxam, acetamiprid, thiacloprid and clothianidin registered varying levels of resistance for all the locations studied. The resistance ratio was high in imidacloprid (3.35, 8.57, 9.15 and 12.27 fold respectively) and the lowest in dinoferuran (1.86, 5.13, 6.71 and 9.88 fold respectively). Furthermore, the enzyme activity ratio (glutathione-S-transferase) was relatively greater, and corresponded to the higher LC50 values of neonicotinoids for very high, high, medium and low pesticide usage areas. Our study suggested that the higher activity of the detoxifying enzyme in the resistance population of cotton leafhopper apparently has a significant role in endowing resistance to neonicotinoid groups of insecticides. However, this study recommends using neonicotinoids in cotton growing areas with caution.
