Organic manures are a valuable potential source of N and organic matter. They play an
important role in the improvement of the physical, chemical, and biological properties of soil
with an increase in the microbial population in the soil. Hence, a field study to know the
effect of conjoint use of organic manure on yield and nutrient status of soybean in Inceptisol
was conducted during kharif 2021-22, on the Research field of Organic Farming Research
and Training Centre, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. Revealed the
effect of organic sources of nutrients on the yield and soil properties of soybeans. Among
various treatments, the higher concentration of available nitrogen, phosphorous & potassium
was found in RDF + FYM 5 t /ha (T 13) followed by 33% FYM + 33% VC + 33% NC (T 3) as
an organic source of nutrients.
Methodology
An experiment was conducted at Organic Farming Research and Training Centre, Vasantrao
Naik Marathwada Krishi Vidyapeeth Parbhani, during Kharif 2018-19. The experiment
design was RBD for thirteen treatments with three replications with a gross plot size of 7.2 m
x 6.0 m and net plot size of 6.3 m x 5.4 m and with 45 x 05 cm spacing.
Results
Soybean yield was determined by the development of the plant from the beginning of
sowing to the harvest period, where the role of fertilization was of great importance. The
application of different organic and chemical fertilizers would affect one or all of its yield
components. Data from Table showed that among nutrient source applications the chemical
fertilizer as RDF with FYM the treatment T13 i.e. RDF + FYM @ 5 t ha -1 recorded the
highest available macronutrient in soil which was found significantly superior over the rest
of the treatments. However, the use of organic sources of nutrients affected soybean
available macronutrients in soil, and data revealed that the effect of various organic sources
on soybean yield was found to be significant. The nutrient status for available
macronutrients was found to be significant for available nitrogen. Among various
treatments higher concentration of available nitrogen, phosphorus and potassium was found
in T3 followed by T2 of an organic source of the nutrient. The differences for pH, EC,
Resource conservation and rainfed agriculture
