Grain and Fodder: Sorghum bicolor

Tuesday, June 1, 2010

Crop: Grain and Sorghum
Result: Increased yield
Location: India

Sorghum is a vigorous annual grass adapted to the drier environmental zones in Africa, Asia, the Americas, and Australia. Annual world production approaches 40-45 million tons from approximately 40 million hectares of land, making sorghum the 5th most important cereal. Sorghum is a vital source of grain and fodder for many of the poorest countries of the world, especially those in the arid tropics. Sorghum is adapted to dry poor soil ecologies through an extensive root system and waxy bloom on leaves to reduce water loss.

Two large scale independent controlled field studies have been completed in India to investigate potential grain and fodder yield increases at different methods and rates of Agrostim application over the growing season in Tropical Arid environmental conditions.

A. Sorghum Grown under Rabi Conditions:

Institute: Indian National Research Center for Sorghum Rajendranagar, India

Season: Rabi – October to November 1996

Sorghum Type: Genotype M 35-1

Soil Type: Medium deep black soil with an elevated soil pH.

B. Sorghum Grown under Kharif Conditions:

Institute: All India Coordinated Sorghum Improvement Project Sorghum Research Station, Palbhani, India

Season: Kharif – 1996/1997

Sorghum Type: Genotype CSH – 9

Soil Type: Medium deep black soil with high initial nutrient status.
