Higher yield of cotton

The soil available N, P and K were significantly higher in treatment supplemented with application of 100 per cent RDF through soluble fertilizers by fertigation over 100 per cent RDF through conventional fertilizers. Yield was significantly maximum in application of 100 per cent RDF through soluble fertilizers by fertigation than other treatments.

With the advent of Bt cultivars cotton production is reinvigorated in the country with China being on the verge of being knocked down on the production front. However, of late the stagnating or the decreasing productivity either due to degrading natural resources and faulty practices and/or susceptibility of transgenic cultivars to insect damage, leaf reddening and climate change are making the researcher to take stock of the situation before embarking on agronomic studies with higher yield goals. Hence, the review.

Field experiment was conducted at Agricultural Research Station, Borwat Farm, Banswara during kharif -2011 to find out the optimum plant geometry and fertility levels for inter specific cotton hybrids with three cotton hybrids (USHB-25,PSCHB-901 and DCH-32), two plant geometries (90 x 60 and 90 x 45 cm) and three fertility levels (75,100 and 125 % RDF). Sowing of USHB-25 cotton hybrid gave significantly higher seed cotton yield (2354 kg ha-1 ) over PSCHB-901.

To investigate the water-deficit tolerance, 3 cotton genotypes (Bunny Bt, Pratima and Anjali.) were grown under normal irrigation and water-deficit conditions. Moisture is a key factor affecting growth and yield of Cotton in which stress is the most important factor limiting crop productivity due to adverse effect on fruit production, square/boll shedding and lint yield as well as fiber quality properties of Cotton. If water supply is limited during boll development it could result in significantly lower yields. In this study stress imposed with four watering treatments viz.

A field experiment was conducted at Central Institute for Cotton Research Farm, Nagpur for three years in medium deep clay loam soil. The experiment was laid out in RBD design with three replications consist of three herbicide based weed management packages in intercropping of non Bt cotton + soybean and two sole crops. Non Bt cotton+ soybean intercropping reduced seed cotton yields considerably in a year of very 640 mm higher rainfall over normal caused over growth of soybean.

An optimum plant population can maximize the plant output so this field experiment was conducted to know about the Response of different planting density on various genotypes of cotton for yield maximization. In this experiment three cotton genotypes viz. hirsutum cotton (AKH-081), arboreum cotton (AKA-7) and Bt cotton (Balwan), with three plant densities level of 100 %, 150 % and 200 % of normal for respective genotype, were laid out in factorial randomized block design. Bt cotton Balwan recorded higher growth in terms of leaf area, dry matter weight and yield attributes plant-1 .

Present investigation on estimation of yield losses due to major sucking pests of the Bt cotton was carried out on the College Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during Kharif season of the year 2011-12. The Bt hybrid cotton cultivar KDCHH-441 was grown with the plot size of 24 m X 20 m at spacing of 120 cm x 45 cm. The data revealed that significantly higher seed cotton yield 2038.82 kg/ha was recorded from protected plots, while the yield of 1312.70 kg/ha was recorded from unprotected plots.

The present investigation was performed with fifty-three genotypes of Gossypium hirsutum L. cotton to get information on genetic variability, heritability and genetic advance as per cent of mean for yield, yield supporting and fibre quality attributes. The value of PCV was higher than GCV which explains that instead of genotypic component, the environmental component also influences in the expression of the character. The characters like number of bolls per plant, number of flower bearing nodes and seed cotton yield recorded higher values of GCV and PCV.
