Abstract:
Dolichos bean is being grown in an area of about 78 ha in Gariaband district. Mostly local varieties of dolichos bean were cultivated. Though Dolichos bean fetches good price in market, the productivity was lesser due to lesser yield potential of the local varieties. Heavy yield loss even upto 38 % was recorded. To address these problems improved varieties of Doilchos bean were assessed for their performance in Gariaband district. The Farmers practice (T₁) was local variety, technology recommended practice (T₂) was Indira Sem-1 released by IGKV, Raipur and recommended practice (T₃) was Indira Sem-2 also released by IGKV, Raipur. The trials were conducted in five locations of Gariaband district farmers’ field during Kharif 2021. The results of the on farm trials showed that Indira Sem-1 performed better than Indira Sem-2 and local variety. The yield of Indira Sem-1 recorded higher yield (110.34 qtl ha^-1) where as Indira Sem-2 recorded 103.83 qtl ha^-1. The Number of pod per inflorescence was higher in Indira Sem-1 (21.41) where as it was 16.94 in Indira Sem-2 and 12.44 in local variety. The tenderness and quality of pods was good in both the improved varieties than the local variety. The time taken for maturity was higher in Indira Sem-1 Indira Sem-2 and local variety. The yield parameters such as yield per plant, pod length and pod width are recorded to be better in the improved varieties than the local variety. The number of harvests was higher in Indira Sem-1 than Indira Sem-2 and local varieties. All the yield related parameters indicated that the variety Indira Sem-1 was better than Indira Sem-2 and local variety. There was no significant difference among the cost of cultivation among the assessed varieties as the plant protection sprays were similar. But, difference was felt in the higher productivity in T₂ i.e. Indira Sem -1 and hence the net returns.
