Nutrient content as well as uptake of organic guar gum as affected by land configuration and nutrient management under rainfed condition

The investigation entitled, “Nutrient content as well as uptake of organic guar gum as affected by land configuration and nutrient management under rainfed condition” was conducted during kharif season of 2013-14 at Agronomy farm, Dr. PDKV, Akola to study the production potential of guar gum under various land configuration and integrated nutrient management system. Seed and straw yields as well as N, P and K uptake by guar gum (seed and straw) were maximum under the treatment of Opening of furrow in each row and alternate rows compared to flatbed configuration. Nutrient content (N, P and K) in seed and straw was not influenced significantly due to land configuration. Significantly higher grain yield (270.17 kg ha-1) and straw yield (588.35 kg ha-1) was observed under the treatment of Opening of furrow in each row which was at par with Opening of furrow in alternate rows. Highest seed yield (281.71 kg ha-1) and straw yield (598.07 kg ha-1) was recorded with Vermicompost-2.0 t ha-1 than FYM-2.5 t ha-1, Soybean compost-2.0 t ha-1 and control treatments. Nutrient content (N, P and K) in seed and straw was significantly higher in Vermicompost-2.0 t ha-1 compared to rest of the treatments. N, P and K uptake by seed and straw was recorded maximum in application of Vermicompost-2.0 t ha-1. FYM-2.5 t ha-1 and Soybeancompost-2.0 t ha-1 were at par in terms of N, P and K uptake by seed and straw but were significantly superior to control treatments.
