Effect of cutting, phosphorus and potassium fertilization on guar plant (Cyamoposis tetragonoloba) in newly reclaimed soil in Egypt

Abstract

A two year experiment was carried out in newly reclaimed soils (sandy soils) to investigate the effect of cutting and phosphorus and potassium fertilization on the growth, yield, seed mucilage content and seed protein content of guar plant. The results revealed that different cutting treatments significantly decreased the plant weight, seed yield, seed mucilage content and seed protein content. Phosphorus fertilization up to 350 kg super-phosphate (15% P2O5)/feddan* significantly increased plant weight, seed yield, seed mucilage content and seed protein content. Fertilization with 150 kg potassium sulfate (48% K2O)/feddan was quite capable to meet guar plant potassium demands in this kind of soil. Without cutting plants, fertilization with 350 kg super-phosphate and 150 kg potassium sulfate/feddan resulted in the highest seed yield, seed muculage content and seed protein content.

Effect of Mineral Fertilization and Cutting Numbers on Growth and Productivity of Guar Plant I. Effect on Vegetative Growth Parameters

“…Our results were in the line with those observed by Omer et al (1993) on guar plant; Tabacco et al (2002) on lucerne; Moniruzzaman et al (2008) on kangkong plant; Tehlan and Thakral (2008), Moniruzzaman and Rahman (2015), Abd El-Azim and Waleed (2016), Singh et al (2017) and Bhapkar et al (2019) on coriander;Foidl et al (2011), Lawal et al (2015 and Ibrahim (2017) The interaction between main and subplot treatments (A × B) was significant for shoot fresh and dry weights/plant in both experimental seasons as clearly shown in Table (2). The heaviest weights were obtained by fertilizing guar plants by mineral fertilization treatment N3P3K3 (500 kg/fed) without cut (NC0) in both seasons (850.16 and 859.20 g, respectively for shoot fresh weight and 186.06 and 197.30 g, respectively for shoot dry weight.…”

“…Our results are in agreement with those reported by Omer et al (1993) The interaction between the main and sub-plot treatments (A × B) was significant for plant height in both seasons. The tallest plants were recorded with the plants fertilized with N3P3K3 without cut (122.72 and 122.84 cm in both seasons, respectively) or fertilized with N2P2K2 without cut (111.56 and 112.16 cm in both seasons, respectively).…”

“…Our results are in the line with those studied by Omer et al (1993) The interaction between mineral fertilization and number of cuts (A × B) was significant for number of branches/plant in both experimental seasons. The highest number of branches/plant was produced from plants received the highest level of mineral fertilization (N3P3K3) in addition to three time cuts in both seasons (21.24 and 18.00 branches/plant in both seasons, respectively).…”

Growth and Yield Performance of Five Guar Cultivars in a Mediterranean Environment

“…Although doubts remain about its centre of origin, guar probably originated and developed in the arid areas of the Indo-Pakistan subcontinent (Whistler and Hymowitz, 1979). It needs a hot climate, takes advantage of irrigation (Alexander et al, 1988) and fertilization (Omer et al, 1993), has a high tolerance to salinity (Ashraf et al, 2005;Francois et al, 1990) and a good capability to fix atmospheric nitrogen (Wetselaar, 1967;Elsheikh and Ibrahim, 1999). Guar seeds contain about 4% edible oil (Mehta and Ramakrishanan, 1957), and a protein content ranging between 27 and 37% (Whistler and Hymowitz, 1979).…”

Screening of guar accessions [Cyamopsis tetragonoloba (L.) Taub.] for higher yield potential under irrigated conditions

“…Guar is mainly grown in arid and semi-arid regions of Pakistan, India, South Africa and United States (Ashraf et al, 2005). It requires a hot climate, takes benefit of fertilization (Omer et al, 1993) and irrigation (Alexander et al, 1988). Guar has a high salinity tolerance (Farencois et al, 1990;Ashraf et al, 2005) and a good capability to fix atmospheric nitrogen (Wetselaar, 1967;Elsheikh and Ibrahim, 1999;Sultan et al, 2012;Sohrawardy and Hossain, 2014).…”
