An On-Farm Trial (OFT) was conducted over three consecutive years (2021–22 to 2023–24) across multiple farmers’ fields under the jurisdiction of KVK Banaskantha-II to assess the impact of liquid organic nutrients and micronutrient applications on the growth, yield, and quality of chilli (Capsicum annuum L.). Three treatments were evaluated: T1 (control, no foliar application), T2 (foliar spray of Novel Liquid Fertilizer at 1.0% during flowering and fruiting stages), and T3 (foliar application of ZnSO₄ thrice at 30, 40 and 50 DAT and one Spray 19:19:19 + Mn @ 1% at 60 DAT). The results indicated that the maximum average plant height (79.24 cm) was observed in T2, followed by T3, while the lowest height (63.20 cm) was recorded in T1. The number of fruits per plant was highest in T2 (89.15), followed by T3 (84.95), and lowest in T1. Regarding fruit quality parameters, T3 recorded the greatest average fruit length (8.51 cm) and fruit weight (3.85 g), followed by T2 (7.93 cm and 3.64 g, respectively), with T1 showing the lowest values. In terms of yield, the highest total fruit yield was recorded in T3 (163.60 q/ha), followed by T2 (158.48 q/ha). Economic analysis revealed that T3 had the highest gross cost (₹88,923/ha), but also produced the highest gross return (₹2,12,681/ha), resulting in the maximum net return (₹1,28,874/ha) and benefit-cost (B:C) ratio of 2.39. These findings suggest that the integrated application of ZnSO₄ with balanced nutrients (19:19:19 + Mn) can significantly enhance chilli productivity and profitability under field conditions

Chilli, On farm trail, Growth parameter

The study clearly demonstrates that foliar applications of novel fertilizers and micronutrients addition to the recommended dose of fertilizer result in superior growth and yield compared to traditional practices. The foliar sprays not only improved fruit size but also contributed to better fruit development, which was reflected in the higher average fruit weight. These findings suggest that adopting application of Micronutrients or Novel liquid organic nutrient in chilli in this region could help to achieve higher yields, better fruit quality, and overall improved productivity in chilli farming
