Abstract

Despite the vital importance of second cropping in paddy fields, a large area of these lands remains uncultivated due to lack of introduction of suitable crops for second cropping and the lack of providing technical solutions to increase crop yields. Products such as beans, pumpkins, and leafy vegetables have the ability to be re-cultivated in paddy fields, which, along with the use of appropriate agricultural techniques, can be considered a major factor in the success of the re-cultivation project in these lands. Therefore, this study was conducted in order to investigate the possibility of producing hull-less pumpkin hybrids as a second crop in paddy fields. For this purpose, in this research, 15 hybrids were investigated in the form of randomized complete block design with three replications in the research farm of Guilan University during the summer and autumn seasons in two conditions, no-tillage and conventional tillage. Since hull-less pumpkin seeds are used, the genotype that has the highest seed yield and the weight of 1000 seeds is more desirable. Therefore, genotype 1116 is suitable for seed production. This genotype, which has an indeterminate growth habit, had the highest number of lateral branches, number of female flowers, seed thickness, and weight of one seed in the no-tillage system. In this test, the no-tillage system showed no difference compared to the conventional tillage system, which means that the no-tillage system can be used for planting in sustainable agriculture for optimal use of soil resources.
