Abstract:

The goal of this study was to see how a combination of Rhizobium inoculant, S, and Zn nutrients affected chickpea nodulation and yield (Cicer arientinum L.) at Gewane, northeastern Ethiopia. The experiment included 12 treatments arranged in factorial combination of levels of inoculation (Rhizobium inoculated, un-inoculated), three rates of S (0, 15, 30 kg Sulphur ha-1) and rates of Zn (0, 1.5 kg Zinc ha-1). The treatment becomes laid out in randomized complete block design with 3 replications.  Analysis of variance showed that yield and yield associated parameters (main branches, number of pod, quantity of seed, hundred seed weight, grain and straw yield), crop phenology (days to 50% flowering and days to physiological maturity), nodulation scores (nodule amount, nodule volume, nodule dry weight, effective nodule and nodulation score), N and P uptake at both locations had been significantly affected by the treatments. The best (1775.5 kg ha-1) suggest rate of seed yield over locations changed into acquired from blended costs of rhizobium and 30 kg S ha-1 which led to 28 % (389 kg ha-1) growth over the control. Consequently, rhizobium inoculation with rate of 30 kg S ha-1is recommended for chickpea production on the experimental site.
