| Abstract:
The paper reveals detailed information and rationale of potato-muskmelon-bittergourd cropping sequence in relation to time of sowing and harvesting of new potato genotypes as affected by varying levels of potassium fertilization on the sandy loam soil of Punjab (India). It was further aimed at demonstrating the yield potential of new potato genotypes particularly the tuber quality thus attaining improved profitability by farmers during the glut period. Three varieties were evaluated under the varying levels of potassium during 1989–90 and 1990–91. So far as the economic viability and ecological sustainability is concerned, cropping system i.e. potato (var. JH-222)-muskmelon (var. Pb.Hybrid)-bittergourd gave remunerative returns. The yield data also revealed that JH-222 (a new variety released in 1989) gave maximum yield (260 q/ha) followed by Kufri Badshah and Kufri Chandramukhi. Tuber size was affected significantly under the influence of varying levels of potassium. | |
