Quality of Rice Grain is Influenced by Organic and Inorganic Sources of Nutrients and Antioxidant Application

Abstract

The present research was conducted to study the influence of organic and inorganic sources of nutrients as well as antioxidant on rice quality. The experiment was designed in split-split plots with four replications, where main plots were assigned to nitrogen (0, 55, 110 and 165 kg N ha−1) and sub plots were allocated to compost (0, 3.5 and 7 tons ha−1), while the sub-sub plots were assigned to ascobien (control, spraying with ascobien in two times at 15 and 30 days after transplanting (DAT), spraying with ascobien three times at 15, 30 and 45 DAT). The result indicated that grain quality traits were significantly influenced by the organic and inorganic fertilizers, and ascobien. The percentage of hulling, milling and amylose were positively and significantly influenced by nitrogen, organic and antioxidants application. Most of studied characters produced the highest values with the organic fertilize were combined with nitrogen and antioxidants. Application of 110 kg N ha−1, 7 t ha−1 compost and two or three spraying of ascobien, 110 kg N ha−1 or 3.5 t ha−1 compost and three times spraying and 55 kg N ha−1, 7 t ha−1 compost and two times spraying could be recommended for optimum grain quality of Sakha106 rice variety. It can be concluded that compost along with the foliar application of ascobien can be saved from 50 to110 kg N ha−1, without reducing grain quality. It can be the key to reduce the need for chemical fertilizers and decrease the cost of production with keeping healthy soil.

Feeding Preference and Development of Sitophilus oryzae L. on Organic and Inorganic Rice Cultivation

“…However, the ash and protein content of inorganic rice is higher than those of organic rice for both varieties. Those results are in line with Bagchi et al (2016), Gangmei & George (2017), Gharieb, Metwally, Abou-Khadrah, Glela, & El Sabagh (2017), and Paule, Gomez, Juliano, & Coffman (1979), as inorganic rice has a softer kernel and lower phenol and carbohydrate content, while organic rice has lower ash and protein contents. Ingver, Tamm, & Tamm (2008) reported that inorganic barley and wheat have larger seeds and higher protein contents compared with organic grains.…”

Some Nutrients Availability in Rice Soil under Utilization of Organic and Inorganic Fertilizers

“…the number of panicles per plant, filled grains percentage and the number of grains per panicle. Similar trend was found by Metwally et al, (2011), Gharieb et al, (2016), Sudhakar et al, (2018) and Ramesh, (2019. Uddin et al, (2013) found that, NPK application resulted in increasing photosynthetic efficiency as well as translocation of assimilates which reflected in increases in most of grain yield components.…”

“…Rice straw contained less total N and higher C:N ratio than compost and farm yard manure (Table 3). Similar trends were obtained by Ahmed and Naeem (2012), Metwally (2015), Gharieb et al, (2016), Halder et al, (2020), Qaswar et al, (2020 and Sahu et al, (2020). Means of each factor designated by the same latter are not significantly different at 5% level using Duncan's Multiple Range Test.…”

SUSTAINABLE MAIZE (Zea mays L.) PRODUCTION UNDER DROUGHT STRESS BY UNDERSTANDING ITS ADVERSE EFFECT, SURVIVAL MECHANISM AND DROUGHT TOLERANCE INDICES

“…While a positive relationship between amount of irrigation water and grain yield at different Farmyard manure (FYM) treatments under drought stress condition, indicating that FYM in combination with amount of irrigation help to survive plants under deficit water stress condition (Abd El-Wahed et al, 2015). Organic fertilizers might play an important role to solve environmental pollution problems that caused by agroindustrial wastes (Preap et al,2002 ;Gharieb et al , 2016).The combined chemical and poultry manure fertilization (50:50) produced the maximum yield and its traits of maize (Nasim et al (2012). According to Azab (2016) application of half rate of the chemical NPK combined with bio-fertilizers was effective and logic to achieve the maximum productivity under the condition of investigation in maize.…”
