Assessing the influence of integrated nutrient management on growth and yield of Black gram (Vigna mungo L.)

Abstract

The present study was undertaken to observe the effect of combined application of organic manures and inorganic fertilizers on growth, yield and yield contributing characters of black gram. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The experiment comprises eight treatments viz. Control (no application of manures and fertilizer), Recommended doses of fertilizer (RDF), Cowdung @ 5 t ha-1 + 50% of RDF, Poultry manure @ 5 t ha-1 + 50% of RDF, Vermicompost @ 5 t ha-1 + 50% of RDF, Cowdung @ 5 t ha-1 + Poultry manure @ 5 t ha-1 + 50% of RDF, Cowdung @ 5 t ha-1 + Vermicompost @ 5 t ha-1 + 50% of RDF and Poultry manure @ 5 t ha-1 + Vermicompost @ 5 t ha-1 + 50% of RDF. Combined application of organic manures and inorganic fertilizers exerted significance influence on growth, yield and yield contributing characters of black gram. At growth, the tallest plant (38.74 cm), the highest number of leaves plant-1 (15.55), leaf dry weight plant-1 (6.99 g) and stem dry weight plant-1 (3.01 g) of black gram at 50 days after sowing (DAS) were obtained from poultry manure @ 5 t ha-1 and vermicompost @ 5 t ha-1 along with 50% of RDF. While, at 50 DAS, the highest number of nodules plant-1 (55.22) was recorded from cowdung @ 5 t ha-1 along with 50% of RDF and the highest number of SPAD value plant-1 (42.03) was found in poultry manure @ 5 t ha-1 along with 50% of RDF. Again, at maturity, the highest number of seeds pod-1 (5.86), yield plant-1 (7.77 g), grain yield m-2 (130.70 g) and total dry weight plant-1 (17.21 g) were obtained from poultry manure @ 5 t ha-1 and vermicompost @ 5 t ha-1 along with 50% of RDF. Therefore, it can be concluded that poultry manure @ 5 t ha-1 and vermicompost @ 5 t ha-1 along with 50% of RDF combination might be a promising practice for black gram cultivation.

Influence of seedling age and integrated nutrient management on growth and yield of aromatic rice (cv. BRRI dhan34)

“…Despite having year-round ideal agroclimatic conditions for rice cultivation, the average national output of grain in Bangladesh is somewhat lower than that of other nations that also produce rice (Marzia and Najnine, 2022). According to several research, factors such as nutrient mining, soil organic matter depletion, reduction in soil aggregates, and others have been implicated as causes of yield stagnation and loss of agricultural productivity (Sohel et al, 2016;Mahamud et al, 2022). The factors contributing to poor yield also include unwise nutrient management (Nila et al, 2018).…”

Growth and yield performance of hybrid rice varieties under varying zinc levels

“…In Bangladesh population growth is contributing to an ever-increasing demand for rice. Additionally, in recent years, the depletion of soil organic matter, the mining of nutrients, and the loss of soil aggregates all contributed to a decline in efficiency of soil (Sheel et al 2015;Mahamud et al 2022;Sabil et al 2023). To counter this problem Bangladesh Rice Research Institute has developed several high yielding rice varieties among them BRRI hybrid dhan2, BRRI hybrid dhan3 and BRRI hybrid dhan5 are cultivated in Boro season in Bangladesh.…”
