Abstract
A field experiment entitled “Effect of phosphorus and biofertilizers on
growth and yield of mungbean [Vigna radiata (L.) Wilczek]” was conducted at
Agricultural Research Station, Mandor, Jodhpur during kharif season of 2018. A field
experiment was laid out in randomized block design (RBD) with nine treatments and
replicated thrice. The treatments taken in the investigation were Control (F0), 20 kg
P2O5 ha-1 (F1), 40 kg P2O5 ha-1 (F2), 20 kg P2O5 ha-1 + PSB (F3), 40 kg P2O5 ha-1 +
PSB (F4), 20 kg P2O5 ha-1 + Aspergillus awamori (F5), 40 kg P2O5 ha-1 + Aspergillus
awamori (F6), 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg P2O5 ha-1
+ PSB + Aspergillus awamori (F8). According to treatments, seeds of mungbean were
inoculated with PSB + Aspergillus awamori, while different doses of phosphorus
were applied in the soil.
Among growth attributes viz. plant height (14.73, 46.08 and 49.48 cm), dry
matter accumulation plant-1 (3.02, 21.45 and 24.63 g) at 30, 60 DAS and at harvest,
respectively, while final plant population (3.29 lakh ha-1), number of branches plant-1
(7.81) as well as yield attributing characters viz. number of pods plant-1 (48.34), seeds
pod-1 (12.57) and 1000-seeds weight (44.66 g) resulted in higher seed yield (1583 kg
ha-1) and stover yield (3504 kg ha-1) were recorded significantly under treatment
applied with 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) followed by 20 kg
P2O5 ha-1 + PSB + Aspergillus awamori (F7). However, 20 kg P2O5 ha-1 + PSB +
Aspergillus awamori (F7) and 40 kg P2O5 ha-1 + Aspergillus awamori (F6) were
statistically at par with each others with respect to growth attributes, yield attributes
and yield of mungbean.Similarly, integrated application of 40 kg P2O5 ha-1 + PSB + Aspergillus
awamori (F8) recorded significantly higher phosphorus content in seeds (0.477%) and
stover (0.273%) results in higher uptake of phosphorus by seeds (7.56 kg ha-1) and
stover (9.56 kg ha-1) of mungbean and showed significant superiority over rest of the
treatments. However, 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7) and 40 kg
P2O5 ha-1 + Aspergillus awamori (F6) were statistically at par with each others with
respect to phosphorus content and uptake by seeds and stover. Increase in seed and
stover yield, which subsequently improved gross returns ( 1,31,440 and 1,20,787
ha-1), net returns ( 1,08,671 and 98,960 ha-1 ) and B: C ratio (5.77 and 5.53 ) and
recorded highest under 40 kg P2O5 ha-1 + PSB + Aspergillus awamori (F8) followed
by 20 kg P2O5 ha-1 + PSB + Aspergillus awamori (F7), respectively
