The study tested different organic nutrient combinations on bottle gourd plants. They found that a mix of farmyard manure, poultry manure, and biofertilizers led to the longest vines. Another mix including castor cake, poultry manure, and biofertilizers resulted in the highest yield per plant. A combination of neem cake, poultry manure, biofertilizers, and other additives produced the largest fruit diameter. These organic nutrients also improved soil properties, increasing nitrogen, phosphorus, and potassium levels.
