Effect of integrated use of phosphorus, biofertilizers and organic manures on soil available nutrient status and yield of greengram (Vigna radiata L.)

Abstract

The effect of inorganic phosphorus, phosphate solubilising bacteria and vermicompost on yield of greengram and available nutrient status was studied during Kharif 2016 at Agricultural College, Polasa, Jagtial, Telangana state, India. The experiment was conducted with three levels of phosphorus (0, 75 and 100 % RDP), phosphate solubilising bacteria (0 and 2 kg ha -1 ) and vermicompost (0 and 5 t ha -1 ). The results revealed that grain and haulm yields were increased with increasing inorganic P levels and when the crop was supplemented with PSB and vermicompost. Significantly higher grain (1033.33 kg ha -1 ) and haulm yield (1625.66 kg ha -1 ) were recorded when the crop was integrated with 100 % RDP along with PSB and vermicompost. Results also indicated that there was a significant build-up in available N, P, K and S status with increasing inorganic P levels, seed inoculation with PSB and vermicompost application. Thus, it shows positive influence by the application of phosphatic fertilizers, organic manures and biofertilizers.

Enhance the productivity and nutrient use efficiency of greengram (Vigna radiata) through inorganic nutrients and biofertilizers

“…Data further revealed that significantly higher yield attributes (number of pods/plant, number of seeds/pod and seed test weight) and yield (seed and stover) were obtained under T 4 (75% of recommended NPK+ seed inoculation by Rhizobium @ 10 g/kg seed + soil application of PSB and KSB each @ 5 kg/ha) treatment over other treatments. Improvement in yield attributes and yield under T 4 treatment was may be attributed to the increased vegetative growth due to effective utilization of nutrients provided by rhizobacteria (N-fixer, P and K solubilizers) and potential production and partitioning of photosynthates as also stated by Kumawat et al (2010) and Bhavya et al (2018 ).…”

“…It also improve the chlorophyll content in plants that regulates the photosynthesis and accumulation of food in plant as stated by (Singh and Sharma 2011). Protein content (22.5%) and yield (238.5 kg/ha) was also found maximum with T 4 (75% of recommended NPK+ seed inoculation by Rhizobium@ 10 g/kg seed + soil application of PSB and KSB each @ 5 kg/ ha) treatment might be due to more N-uptake as suggested by (Bhavya et al 2018).…”

“…The amount of soil N, P and K can be important indicators of soil fertility, especially the available nutrients that can be directly absorbed and utilized by plants (Bhavya et al 2018). In all treatments, HF and BW increased the preplant soil AN, AP and AK contents (Fig.…”
