The goal of this study was to see how Rhizobium inoculation
and phosphate rock interacted on two distinct kinds, KS20 and N26. In Tharaka
Nithi County, green gramme is a key source of food security. As a result,
increasing productivity requires a low-cost, long-term agricultural production
system. The legume/Rhizobium symbiosis, when combined with phosphate rock,
provides a natural method for increasing green gramme nitrogen fixation. As a
result, the purpose of this research was to determine how Rhizobium and
phosphate rock fertiliser influenced the N26 and KS20 cultivars' growth and
yield characteristics. For two seasons, November 2019 to January 2020 and
February to April 2020, the research was conducted at Chuka University
Horticultural Research Farm. A Randomized Complete Block Design was used to set
up a 2x2x2 factorial experiment (RCBD). Variety (N26 and KS20), phosphate rock
(0 and 30 kg P ha-1) and Rhizobium MEA 716 were the three components (0 and 100
g ha-1). The experiment included eight treatments, each of which was repeated
three times. Plant height, number of leaves, branches, pods, total dry biomass,
shoot and root dry weight, and grain output were all measured every two weeks
on four randomly selected plants. The data was analysed using SAS (Statistical
Analysis Software). Significant means are separated using Least Significant
Difference at a probability threshold of 5%. (LSD). The combined application of
Rhizobium MEA 716 Rhizobium 100 g ha-1 and phosphate rock 30 Kg ha-1 phosphate
under variety in treatment (R1P1V2) resulted in significantly (P0.05) higher
plant height (76.07 cm), number of branches (14.08 plant-1), shoot dry biomass
(52.01 g plant-1), root dry biomass (7.60 g plant-1), total dry biomass (146.4
g plant-1), number of pods (84 (R1P1V1). As a consequence, mixing Rhizobium MEA
716 100 g ha-1 with phosphate rock 30 Kg ha-1 under the variety KS20 resulted
in the KS20 variety having better growth attributes and yield components than
the N26 variety. Based on these findings, the research area was suggested to
use 100 g ha-1 Rhizobium MEA716 and 30 Kg ha-1 phosphate rock under variety
KS20 for improved and long-term green gramme production.
