“…This was probably due to greater temporal and spatial complementarity. The results are in agreement with the findings of [25], who observed that combined application of 100% recommended dose of NPK and bio-inoculants recorded the maximum CEY of 2,460 and 2,190 kg per hectare in 2007 and 2008, respectively. CEY differed significantly due to INM treatments (Table 3).…”

Aims: Field experiment was conducted to study the integrated nutrient management on yield, all yield components and resource use efficiency of cotton and soybean intercropping system. Study Design: Randomized complete block design with three replications and twenty treatments. Place and Duration of Study: Plot number ‘101’ of ‘D’ block, All India Coordinated Research Project, Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka (India) during June 2016. Methodology: As per the treatments, organic manure (FYM) and green leaf manures (gliricidia and pongamia) were applied 15 days before sowing of the crop. Vermicompost was applied on the spot to soil before dibbling of seeds in cotton and soybean intercropping system in 1:2 row proportions, soybean introduced as intercrop in cotton with row spacing of cotton 120 cm and soybean 30 cm. Results: Results revealed that all the yield components like number of bolls per plant, boll weight, seed cotton yield and cotton stalk yield in cotton and number of pods per plant, seed weight per plant, seed yield and haulm yield were higher under sole crop. Application of 150 and 125% RDF for cotton and soybean intercropping system found higher yield and yield components of cotton and soybean. However, the land equivalent ratio (LER), area time equivalent ratio (ATER) and cotton equivalent yield (CEY) were higher in intercropping system than sole crops. Conclusion: Application of 125% RDF for both crops was found to be agronomically feasible, economically viable, environment friendly and in sustainable approach. In addition to this it provides insurance against inter-climatic changes.

“…The cotton crop (Gossypium hirsutum L.) is a species of great importance for the agricultural sector in the world, as highlights the works of Khalafalla & Abdellatef (2008), Almeida et al (2010), Silva et al (2012), Naim et al (2013), Marimuthu & Subbian (2013) and Nazir et al (2014) and, together with the species Gossypium barbadanse L., make up 98% of world production according to Azmat & Khan (2010).…”

The removal of lint from cotton seeds is mainly carried out through chemical delinting, but it is an expensive procedure and requires high technology. The objective was to evaluate the physiological quality of Gossypium hirsutum L. seeds delinted by flaming using a thermal delinter prototype. Cotton seeds BRS 286 were flamed in nine settings intensities and compared to chemical delinting and seeds with lint. We analyzed the water content, germination, first count, germination speed index (GSI), length and dry mass of roots and shoots. Using a completely randomized design and the means were compared by Scott-Knott test at 5% probability. In evaluating, the germination percentage did not differ between treatments with chemical and thermal low intensity delinting compared to the control. In vigor tests were observed higher mean values of the chemical treatment to the other treatments, except in GSI test and root dry weight when subjected to thermal delinting of low and medium intensity. The delinting made through the prototype enables efficient results, as well as the chemical delinting with sulfuric acid, without affecting germination and vigor when flamed with low and middle intensity, regardless of the number of active burners.
