MG 50-10A, CES 35, CES 14, and ARV 20 were the varieties used in the
experiment. Among the five varieties only ARV 20 reacted as moderately
resistant. CES 14, though susceptible to anthracnose gave the highest average
grain yield of 180.37 g per plot of sq. m at varying inoculum level. CES 35
gave the least average yield with only 77.78 g/plot. Decrease of functional
leaf area, premature drying of leaves and pod abortion caused the reduction in
yield. The control plants (not inoculated) gave the highest average number of
pods/plant, number of seeds per pods, plant height and grain yield/plot while
the plants inoculated with the highest inoculum density gave the least.
Reduction yield due to the disease was directly proportional to the inoculum
level. [ASJ

(Colletotrchum lindemuthianum) on mungbean as influenced by plant population
density. CMU JOURNAL OF AGRICULTURE, FOOD AND NUTRITION, v.4(4):338-358.
[En] [En Abst] (A:PS)
Two mungbean varieties, M-576 and CES-87 exhibited different reactions to
anthracnose. In both varieties, plant population density affected plant height
at different stages of crop development. The height of the plant increased with
increasing planting densities. Among the two varieties evaluated, CES-87 was
more susceptible to the disease than M-576. The number of pods/plant differed
between varieties and planting densities. The higher number of pods was
obtained from planting densities of 15, 20, 25 and 30 plants/linear meter in
both varieties. Likewise, number of seeds/pod varied at different plant
population densities. The occurrence of anthracnose increased with increasing
densities; however, differences in varietal characteristics contributed much to
the susceptibility and resistance of the crop. Regardless of the variety used,
the yield of mungbean was observed to increase with increasing densities up to
30 plants/linear meter. [AS/EMS]

Eight fungicides were tested against blackgram rust (Uromyces
appendiculatus). Baycor 200 EC (750 ml/ha) was significantly superior to the
other treatments with 98.8% reduction in rust incidence and also gave a marked
increase in yield. [THH]
