Studies on the Use of Mineral and Bio Nitrogen Fertilizer With Some of Growth Regulators on Growth and Yield of Cotton Vatiety Giza 80

Abstract

Two field experiments were carried out at Sids Agricultural Research station, Beni-suef Governumberrate in 2008 and 2009 seasons, to study the response of growth, fruiting and yield of the Egyptian cotton cultivar Giza 80 (G. barbadense L.) to organic manure (sheep manures) alone or combined with mineral nitrogen fertilizer and foliar application with Kinetin and Gebirline GA 3 . The treatment included the control treatment, one concentration of each of kinetin (5 ppm) and GA 3 (100 ppm) which sprayed at the squaring stage obtained could be summarized as follows:The combined application of 30 kg N / fed. as sheep manures a long with 30 kg mineral N / fed. as ammonium nitrate significantly increased plant height, Number of fruiting branches / plant, Number of open bolls / plant, boll weight in the form of seed cotton yield (feddan), seed index and chemical composition of leaf as compared with the control. (ammonium nitrate)in both seasons. Generally, the application of sheep manures at rate of 30 kg N / fed combined with 30 kg N / fed. (ammonium nitrate) and sprayed by Kinetin gave the highest cotton yield and yield components in both seasons. The studied treatments had insignificant effect on earliness % and fiber quality in both seasons.

​Response of Rainfed Bt Cotton to Different Crop Residues Application on Yield, Soil Fertility and Nutrient Uptake under Deep Black Vertisols

“…Integrated application of organic and inorganic fertilizers increased the growth attributes of cotton. This result confirmed with the work of Gebaly (2011) and Balamurugan and Sudhakar (2012). Uniformity ratio (%) = 50 per cent span length…”

Effect of Organic Manure and Foliar Application of Boron on Morphological and Economic Parameters of Sindh-1 and CKC-3 Cultivars of Cotton Under Semi-arid Climate

“…Previous study also suggested that the soil applied farm yard manure and compost significantly increase the plant height (cm), sympodial branches, bolls per plant in transgenic and BT cotton (Jan et al, 2020). Studies also suggested that the FYM and boron significantly increase the boll bearing branches in cotton crop as well as improve the plant height (GEBALY, 2011;Kassem, Hamoda, & Emara, 2009;Qamar et al, 2020;Sawan, Mohamed, Sakr, & Tarrad, 2000). A comparative observation in present study also suggested that the FYM and boron significantly improve the growth characteristic of CKC-3 than that of Sindh-1.…”

Effect of some different types of nano-fertilization on the yield and quality of cotton.

“…The most noteworthy UHM length (35.90 and 35.97 mm), UI (88.10% and 88.37 %), fiber strength (46.87 and 46.90), and MIC (4.37 and 4.57) in 2019 and 2020 seasons, individually was registration from establishing of nanochitosan (NPK) with G. 96. Comparative outcomes were likewise revealed by (Corradini et al 2010 andGebaly 2011).…”
