Effect of Rhizobium and PSB in Combination with Phosphorus on the Enrichment of Soil Fertility and its Effect on Yield of Green Gram (Vigna radiata L.)

Abstract

The field experiments were conducted during kharif season for the two consecutive years at the crop research farm, Department of soil science, RRS Wadura, Sopore, SKUAST-K to study the effect of PSB, Rhizobium and different levels of phosphorus on growth, nutrient uptake, yield of green gram (Vigna radiata L) and soil properties. Different levels of phosphorus (30, 60 and 90 kg/ha) as per treatment and bio-fertilizers (Rhizobium and PSB) were applied. The combined application of phosphorus @ 60 kg/ha and Rhizobium resulted in significant higher plant height (cm), no of branches, no of leaves, no of nodules, available N, P and K in soil. It gave highest yield (14.39 q/ha).

Effect of Planting Geometry and Nutrient Management on Yield, Economics and Quality of Dwarf Rice Bean (Vigna umbellata) under Rainfed Condition

“…Such increase in yield might be due to the increase in vegetative growth with the increasing doses of phosphorus. This result is in agreement with those reported by Bhuiyan et al [13] and Nissa et al [14].…”

Effect of biofertilizer and phosphorus on growth and yield of greengram [Vigna radiata (L.) Wilczek]

“…Significant and higher plant height was observed with application of Rhizobium might be due to genetic characteristic and enhanced cell division and elongation. These results are in conformity with those of Nissa et al (2017) [9] . Further, significant increase in plant height with the application of phosphorus may be due to the use of phosphorus levels, which facilitate the synthesis of new cells and the development of roots, this process makes all nutrients and water from deeper soil layers available for increased photosynthetic activity, may have encouraged vegetative growth, which raised the height of the plant.…”

“…The significant and higher seed yield was obtained with the application of Rhizobium might be due to increased nodulation, which subsequently helped to increase nitrogen availability which is a very important factor that influenced seed yield. The similar results were obtained by Nissa et al, (2017) [9] . Further, significantly increased in seed yield with the application of Phosphorous may be due to fact that a larger seed production was eventually achieved by surplus assimilates being stored in the leaves and then translocated into seeds during senescence.…”
