Sorghum (Sorghum bicolor L.,) plays an important role as a grain and fodder crop for both arid
and semi-arid regions of the world. This importance is due to its higher water use efficiency,
relatively good tolerance to drought and salt stresses, and good competitiveness with weeds in
advanced growth stages. Sorghum growth, development, and yield depends on environmental
conditions as temperature and precipitation. Deciding on early or late planting depends on a
farmer’s ability to deal with the risk of poor crop establishment with early planting or the effect
of water or heat stress at reproductive stages with late planting. Since sorghum is cultivated
majorly as a rainfed crop, its productivity is significantly influenced by climatic elements
(Srivastava et al. 2010). Among the cereals in India, sorghum ranks third, next to rice and
wheat. Sorghum is a rich source of carbohydrates, proteins, minerals, and vitamins B1 and B2.
Keeping this in view, this experiment was conducted with the objective to study suitable
variety under suitable weather conditions for optimum production and identify the suitable
sowing date for better growth and yield of sorghum crop.
Methodology
The experiment was carried out for five years during the rabi season from 2016-17 to 2020-21
at Dry Farming Research Station, Solapur (17.65º N 75º 90’ E and 483.6 m MSL) on medium
black soil (60 cm soil depth). The experiment was laid out in a split-plot design with four
replications. Treatments were comprised of four sowing dates i.e. S1: MW 36 (Sept.03-09)
Purva nakshatra, S 2: MW 38 (Sept.17-23) Uttara nakshatra, S 3: MW 40 (Oct.01-07) Hasta
nakshatra, S4: MW 40 (Oct.15-21) Chitra nakshatra. Three sorghum genotypes i.e. V1: M-35-
1, V2: Mauli, and V3: Yashoda were sown at a spacing of 45cm×15cm. The sowing of seed was
done by dibbling method on the respective date of sowing. Recommended packages of
practices were uniformly followed.
Results
Among all the sowing, dates the crop sown at MW 40 (01-07th Oct) S 3 produced maximum
grain yield (808.29 kg ha -1 ) and total monetary returns (Rs. 26633 ha -1 ) over the rest of the
treatments. These results are in concurrence with the findings of (Hulihalli et al. 2016). This
