Effect of tillage practices and fertilizer management on the growth and nitrogen efficiency in soybean

Abstract

A field experiment was performed to evaluate the effects of tillage systems and fertilizer management on the growth and nutrient uptake in soybean. The plant height, fresh weight and dry weight of conventional tillage (CT) were much higher those observed for no-tillage (NT). The highest plant height (128.47 cm) was observed in CT with chemical fertilizer. The plant nitrate concentration was higher (2.29%) in NT with green manure than chemical fertilization. However, nitrogen increased steadily in all treatments, and the highest quantity of total nitrogen (476.7 Kg/ha) was observed in NT with green manure. The NO 3 -N content in the soil decreased gradually just after the vegetative stage. Tillage practices and additional fertilizer application was less effective on the uptake of N, P and K in soybean seeds as compared to NT with green manure. The results postulated that NT strategies with fertilizers might influence the growth characteristics and mineral uptake in soybean.

Effect of Different Tillage Operations on Soil Water Storage, Water Use Efficiency and Productivity of Durum Wheat (Triticum durum Desf.) in Semi-arid Region

“…Environmentally, the soils of semi-arid region suffer from degradation due to intensive tillage practices (Mrabet, 2000). Roy et al (2018) and Abolla et al (2020) reported that No-till systems effect are more beneficial in enhancing soil chemical propriety and soil fertility compared to tillage practices. It is also reported that direct crop seeding reduce about 80% of soil erosion as compared to conventional tillage (Thierfelder and Wall, 2009).…”
