Abstract:
A field experiment was conducted during summer season, 2022 at Agronomy Farm, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Ratnagiri, Maharashtra (India) to study Chitosan fortified briquette implications in water stressed Okra (Abelmoschus esculentus L.) in hot and humid climate of coastal region of Maharashtra where red lateritic soils are prominent. The field was laid out in strip plot design where 3 irrigation stress levels (vertical strip), 8 fertilizer treatments (horizontal strip) which formed 24 treatment combinations and replicated three times to get unbiased and correct data. Variety Konkan Bhendi was used for experimentation. In irrigation stress levels, I₂ (80% ETc irrigation) treatment was most superior for most of the growth and yield attributes. In fertilizer treatment levels, T₇ (100% RDF through 2% chitosan fortified briquettes) and T₅ (100% RDF through 1% chitosan fortified briquettes) were both treatments at par for most of the growth and yield attributes. In treatment interaction, I₃T₇ (60% ETc irrigation with 100% RDF through 2% chitosan fortified briquettes) was most superior for growth and yield attributes with 224.27 q/ha fresh okra fruit yield. Nearly 108.7% yield increase in I₃T₇ treatment interaction over, i.e. I₁T₂ (conventional practice, 100% ETc irrigation with 100% RDF through straight fertilizer) was noted.
