Abstract:
A field experiment was carried out at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during summer 2020-21 to investigate the effect of different spacings under varying fertility levels on summer greengram (Vigna radiata L.).Twelve treatment combinations comprising of four spacings S₁ (30 cm × 10 cm), S₂ (30 cm × 20 cm), S₃ (45 cm × 10 cm) and S₄ (45 cm × 20 cm) and three fertility levels viz., F₁ (75% RDF), F₂ (100% RDF) and F₃ (125% RDF) were evaluated in factorial randomized block design with three replication. Almost all the growth and yield attributes of summer greengram were significantly influenced by spacing. Plant population (at 15 DAS and at harvest), plant height (at 30 DAS and at harvest), seed yield (1133 kg/ha), stover yield (2293 kg/ha) the significantly higher under 30 cm × 10 cm spacing. While number of branches per plant, number of pods per plant and pod length recorded significantly higher under 45 cm × 20 cm spacing. Treatment (S₁) 30 cm × 10 cm spacing recorded maximum net realization (₹ 56596/ha) and benefit: cost ratio (2.85). Among the fertility levels application of 100% RDF (20-40-00 N-P₂O₅-K₂O kg/ha) recorded significantly higher plant height, number of branches per plant, number of pods per plant, pod length, seed yield (1081 kg/ha), stover yield (2229 kg/ha). Treatment (F₃) 125% RDF recorded net realization (₹53579/ha) and benefit: cost ratio (2.80) of summer greengram. An interaction effect between different spacings and fertility levels were found significant with respect number of branches per plant at harvest under treatment combination S₄F₂ (45 cm × 20 cm spacing with application 100% RDF) followed by S₄F₃ (45 cm × 20 cm spacing with application of 125% RDF), S₃F₂ (45 cm × 10 cm spacing with application of 100% RDF) and S₂F₃ (30 cm × 20 cm spacing with application of 125% RDF). Thus, from the foregoing results of one year experiment, it is concluded that for securing higher seed yield and net realization from summer greengram should be sown at the spacing of 30 cm × 10 cm along with application of 100%RDF(20-40-00 N-P₂O₅-K₂O kg/ha) in loamy sand soil.
