“…Plants of the OCS plots on average had 35.5 % more bolls than those of the MMC (Table 3) contributing to yield increases. Number of bolls per plant is the major determinant of seed cotton yield (Blaise et al. 2005a).…”

India is the largest cotton-growing country (8.9 million hectares) in the world and most of the area is raindependent. Large amount of pesticides are used for the control of sucking pests and lepidopterans. Increasing demand for clean organic fibre has led to an interest in organic cotton. However, information on the effects of organic cultivation on fibre quality is limited. Seed cotton yield and fibre quality (length, strength, micronaire and uniformity) were determined for an organic and modern method of cultivation during 3 years (the end of year 11, soil samples were collected and analysed for soil organic carbon content, water-stable aggregates (%), and mean weight diameter. Averaged over 3 years, an additional 94 kg seed cotton ha )1 was produced in the organic over the modern method of cultivation and the difference was significant. The year · treatment interaction was significant. Seed cotton yield in the organic plots was significantly greater than the modern method of cultivation plots in 2003-2004 because of a well-distributed normal rainfall and low pest incidence. The main stem nodes 13-22 accounted for the largest numbers of bolls present on the plant. Plants of the organic plots had significantly (37-71 %) more bolls on nodes 13-27 than those for the plants of the modern method of cultivation. Lateral distribution of bolls on a sympodial (fruiting) branch, was noticed up to fruiting point 11. However, treatment differences were not significant. With regard to fibre quality (length, strength, fineness and uniformity), differences between years were significant. Inferior quality fibre was produced in 2004-2005 because of delayed planting and early cessation of rain. On average, cotton grown under organic conditions compared with the modern method of cultivation had significantly better fibre length (25.1 vs. 24.0 mm) and strength (18.8 vs. 17.9 g tex )1 ). Soil samples of the organic plots had significantly greater C content, water-stable aggregates and mean weight diameter than the modern method of cultivation plots. Differences were restricted to the top layers (0-0.1 and 0.1-0.2 m). Yield benefits of growing cotton in an organic system over the modern method of cultivation are expected to be greater in years receiving normal rainfall and having low pest incidence.

“…Averaged over the 3 years, the wheat and maize relay-planting combined with straw standing or covering reduced soil evaporation by 7.5 and 8.9 % compared to the control. Straw mulching has been proven to be one of the most effective water conservation practices in maintaining soil moisture, reducing water evaporation, and decreasing water consumption (Cantero-Martınez et al 2003;Blaise et al 2005). Usually, straw mulching can slow down air convection on the soil surface and thus decreasing the evaporation of soil moisture (Kang and Zhang 2004).…”

Family farms in populated countries must produce sufficient quantities of food to meet the ever-growing population needs. It is unknown whether innovated farming systems can alleviate this issue. Here, we carried out field experiments in arid northwest China from 2009 to 2012 to determine the response of water use, grain yield, and water use efficiency. We integrated crop intensification via relay-planting and straw mulching in the same system. Straw mulching included stubble standing, straw covering, or straw incorporation to the soil. Results show that wheat and maize relay-planting with straw mulching increased yields by up to 153 % versus monoplanting of maize and wheat. Straw covering approached the highest yield. Relay-planting with stubble standing or straw covering decreased water consumption by 4.6 %. The integrated systems increased water use efficiency by up to 46 % compared to conventional mono-planting maize and wheat.

“…This is closely related with practices regarding treatment (Blaise et al, 2005), sowing date (Pettigrew, 2002), chemical applications (Gormus, 2002) and irrigation (Constable and Hearn, 1981). However, the information regarding fiber quality of organic cotton is rather inadequate.…”

Markets for organically produced high quality cotton (Gossypium hirsutum L.) are projected to increase. Field experiments were conducted in Palamas, Karditsa in Central Greece, to compare the effects of two cropping systems on fiber quality of three cotton cultivars. The experiments, conducted during three years, were laid out in a split plot design with four replicates, two main plots (organic and conventional system) and three sub-plots (cotton cultivars). Findings suggest that fiber quality index (FQI), spinning consistency index (SCI) and multiplicative analytic hierarchy process (MAHP) are three indices that could be integrated in a useful protocol for the evaluation of different cropping systems for cotton cultivation. In particular, our results indicate that in general there was not any superiority of conventional compared to the organic cropping system regarding fiber quality as shown by the above mentioned indices. Regarding the length of the cotton fiber, this was positively correlated with micronair and the uniformity index of the cotton fiber. The organic system resulted to higher values of SCI than the ones of the conventional (1547.9 and 1522.3, respectively). The present 3-years study shows that organic cultivation of cotton can ensure high fiber quality and this was clearly confirmed by means of the several important indices.
