| In order to study the effect of planting time on yield and yield components of mungbean genotypes an experimental investigation was carried out during 2007 in Dezful region. This was designed in complete randomized block design in four replications. Treatments for mungbean genotypes were in four levels (V1) VC3-960-8, (V2) NM92, (V3) Gohar and V4 (CN-9-3) and also planting date in three levels (D1) 22 June, (D2) 6 July and (D3) 22 July 2007. Factors such as, numbers of pod in plant, number of seed in pod, weight thousand seed, economic yield, biological yield, stubble yield, dry weight, length pod, and harvest index were studied. Results shown in first planting date (D1) indicated the highest seed yield, biological yield, stubble yield respectively were 2019.7, 5286.6, 375.7 kg/ha and number 23.27 pod in plat. Therefore highest weight thousand seed (59.79 gr/m2), number seed in pod ( 9.86 ) and harvest index ( 38.78 ) were present respectively in plantings date (D2) and (D3). Moreover, a comparison of genotypes showed that the highest number pod in plant, seed in pod, economic yield, biological yield, stubble yield were 33.5, 11.53, 2362.2, 6488.8 and 4562 kg/ha in NM92 genotype respectively. Whereas thousand seed in genotype CN9-3 obtained the highest and best weight than other genotypes. Reciprocal effects of planting date and genotypes on yield and component yield showed highest economic yield (2662.6 kg/ha), pod in plant (35.5) and seed in pod (17.7) were in treatments D1V2 and D1V3. also the lowest economic yield were in treatment D3V4. The overall conclusion being that the first planting date (D1) and NM92 (V2) genotype are better than other genotypes for cultivation of mungbean in Dezful region. |
