Abstract

The current fertiliser recommendations for cabbage frequently include fixed rates and timing of N, P, and K, over the years, such advice has remained consistent across a wide range of sectors. However, crop growing circumstances, crop and soil management, and climate, which can vary widely from field to field, season to season, and year to year, all have a significant impact on crop growth and the need for additional nutrients. It is not a primary goal of the SSNM (site specific nutrient management) approach to decrease or increase fertiliser use. Instead, it seeks to apply nutrients at the best possible rates and times in order to increase crop production and nutrient usage efficiency, which will result in a high monetary value of the harvest for each unit of fertiliser used. Sustainable agricultural management technologies should be studied in terms of increased productivity, profitability, energy saving and efficiency of agricultural inputs usage by using efficiency indices and sustainable. Field experiment was conducted at College of Horticulture, Bidar, during rabi seasons for two consecutive years (2020 and 2021) The experiment was laid out in randomized block design with three replications. The experimental results revealed that the significantly higher plant height (34.82 cm) was recorded with target yield of 40.0 tha-1 which was on par with target yield of 35.0 t ha-1 (32.56 cm). While significantly lower plant height was recorded with farmer’s practice (25.01 cm). significantly higher plant spread was recorded with target yield of 40.0 t ha-1(38.62 cm) followed by target yield of 35.0 t ha-1 (35.76 cm) as compared to rest of the treatments and significantly lower plant spread was noticed with farmer’s practice (29.75 cm), significantly higher leaf area index was noticed with target yield of 40.0 t ha-1 (0.48) when compared to rest of the target yield treatments.

Conclusion

Any genuine innovation is rendered useless, if it has no practical utility. The adaptation of technology by farmer’s being the main objective; a technology can be more easily adopted, if the farming community is convinced about its benefits. The results obtained in the present investigation revealed target yield of 40.0 t ha-1 followed by target yield of 35.0 t ha-1 are found to be most promising treatments for growth traits.
