Abstract
Field experiment was conducted at Agricultural Research Station, Mandor,
Agriculture University, Jodhpur during kharif season of 2018 on sandy loam soil of
low nitrogen, phosphorus, zinc and iron and medium potassium content with 7.8 pH
of soil. The experiment was laid out in randomized block design (RBD) with 3
replications. The treatments comprised of T1- RDF (common to all treatments),
T2- Soil application of zinc sulphate at 25 kg/ha, T3- Foliar application of zinc
sulphate at 0.5% at 35 DAS, T4 = (T2+T3), T5- Soil application of ferrous sulphate at
25 kg/ha, T6- Foliar application of ferrous sulphate at 0.5% at 35 DAS, T7 = (T5+T6),
T8- Soil application of zinc sulphate and ferrous sulphate each at 25 kg/ha,
T9 = (T8+T3), T10 = (T8+T6).
The results in terms of plant height, dry matter accumulation, number of
branches/plant, number of pods/plant, number of seed/pod, test weight, seed and
stover yield of mungbean increased significantly due to soil application of zinc
sulphate and ferrous sulphate each at 25 kg/ha (T8) over control. The maximum
increment in the growth and yield attributes were due to application of T10 followed
by T9 but these were statistically at par with T8. The significantly higher seed yield
(1323 kg/ha) and higher net returns ( 83,128/ha) was recorded with application of
T8 which was further increased due to T9 and T10 but BC ratio remained highest (4.52)
with T8. Therefore, it was concluded that soil application of zinc sulphate and ferrous
sulphate each at 25 kg/ha can be used for higher grain yield, net return and BC ratio of
mungbean in western Rajasthan conditions. These results are based on one year
experiment hence requires validation through further experiments to formulate
recommendation.
