ABSTRACT
A field trial was conducted to establish the proper inter-row spacing and suitable variety evaluation in Faisalabad, Pakistan. Three mung bean varieties V1, V2, V3 (NM-92, NM-98, and M-1) were grown at three inter-row spacings (S1- 30 cm, S2- 60 cm and S3- 90 cm) respectively. Experiment was laid out in Randomized Complete Block Design (RCBD) with split plot arrangement randomizing varieties in the main and inter-row spacing in the sub-plots. The data recorded were analysed statistically using Fisher's analysis of variance technique and Least Significant Difference (LSD) test at 5% probability level. Highest seed yield was obtained for variety V2 at 30 cm spacing. Among varieties V2 exhibited the highest yield 727.02 kg ha-1 while the lowest seed yield 484.79 kg ha-1 was obtained with V3. The spacing 30 cm showed highest seed yield 675.84 kg ha-1 as compared to other spacing treatments. Low potential varieties and improper agronomic practices may be a serious cause of low productivity in pulses. The interaction of V2S1 exhibited significantly higher yield than other treatments. The lowest seed yield was obtained at V3S1 (462.8 kg ha-1). The higher yield in V2S1 was characterized by more number of plants in narrow spacing of 30 cm (37 plants m-2), plant height of 51.4 cm, higher number of fruit bearing branches (7 per plant), the highest number of pods per plant (18.86), number of seeds per pod (10.06), 1000 grain weight (4.8 g), the highest biological yield (4894.2 kg ha-1) with a harvest index of (17.75) and the highest number of nodules per plant (15) were the components of high yield formation for mung bean variety V2 under the inter-row spacing of 30cm. So it can be concluded that mung bean variety Nm-98 should be grown at inter row spacing of 30 cm under the agro-climatic conditions of Faisalabad.
Key words: Mung bean, row space, yield and varieties.
