ABSTRACT

The field experiment entitled “Influence of Various Sources of Nutrients and Their Combinations on Yield Attributes and Yield of Chandrasur (Lepidium Sativum L.)” was conducted during the Rabi 2018-19 at research cum instructional farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. The soil of the experimental field was clayey in texture and neutral (pH 7.6) in reaction with medium fertility having 0.39 % soil organic carbon, low nitrogen (187.68 kg ha-1), low phosphorous (12.29 kg ha-1) and medium potassium (167.78 kg ha-1) content. The experiment was laid out in randomized block design (RBD) with three replications and ten treatments viz. control (T1), 50 % RDF (T2), 100% RDF (T3), FYM@10t ha-1(T4), FYM@ 5 t ha-1+Vermicompost @1 t ha-1+2 Foliar spray of Cow Urine + Vermi Wash 10% (T5), 50% RDF+Azotobacter @3kg ha-1 + PSB@3kg ha-1 (T6), 50% RDF+Azotobacter @ 3 kg ha-1 + PSB @ 3kg ha-1 +2 Foliar spray of Cow Urine+Vermi Wash 10% (T7), 50% RDF + FYM@ 5 t ha-1+ Azotobacter @ 3 kg ha-1 (T8), 50% RDF + Vermicompost @ 1 t ha-1 +Azotobacter @ 3 kg ha-1 (T9), 50% RDF+ 2 Foliar spray of N:P: K, 19:19:19, @ 3 kg ha-1 (T10) . The test (GA-1) Cvariety of chandrasur was sown as per the treatments with a row to row distance of 30 cm on 5th November, 2018 and harvested on 26th February, 2018. The crop received 12.7 mm rainfall during the study period. The results revealed that among the treatments application 50% RDF with FYM@5 t ha-1 and Azotobacter @ 3kg ha-1(T8) registered significantly highest value of growth parameters viz. yield attributing characters like number of silique plant-1(979.70), number of seeds silique-1(1.84), test weight (1.85 g), seed yield (15.27q ha-1), straw yield (18.59 q ha-1), harvest index (45.09 %).. The application of 50% RDF with FYM@5 t ha-1 +Azotobacter @ 3kg ha-1(T8), FYM @10 t ha-1 (T4) and 100 % RDF (T3) increases the seed yield of chandrasur by 182.25, 153.23 and 142.14%, respectively over the control (T1) treatment. Application 50 % RDF +FYM 5 t ha-1+ Azotobacter @3 kg ha-1(T8) resulted in maximum net returns (₹64243 ha-1), while, the maximum benefit:cost ratio (2.22) was obtained from treatment T3 (100 % RDF). Thus, the present study indicated that application of 50 % RDF combined with FYM @5 t ha-1and Azotobacter @3 kg ha-1as the best treatment to get optimum yield and highest net returns in chandrasur.
