Evaluation of different methods of crop regulation in guava grown under rainfed plateau conditions of eastern India

In Allahabad Safeda guava, foliar application of NAA (200 ppm) resulted in maximum yield of winter season crop. With respect to the profitability of crop regulation through chemical spray the net profit was the maximum in case of 2,4-D (40 ppm) followed by 2,4-D (60 ppm), NAA (200 ppm) and NAA (100 ppm). In case of Lucknow-49, the maximum increase in yield of winter season crop was observed in case of foliar application of NAA (200 ppm). With respect to profitability of crop regulation, the maximum net profit per plant due to crop regulation, it was the maximum in case of NAA (200 ppm). With respect to crop regulation through hand deblossoming in guava cv. Allahabad Safeda, removal of 50% rainy season crop was at par with that in case of 100% crop removal with respect to yield of winter season crop during both the years. Profitability of crop regulation through manual removal of rainy season crop indicated maximum net profit in case of 50% removal of rainy season crop during both the years. In case of Lucknow-49, the maximum total yield was observed in case of 50% crop removal. With respect to profitability of crop regulation, the maximum net profit with sufficient yield was obtained in case of 50% crop removal.
