Effect of Planting Methods and Seed Priming on Mung Bean (Vigna Radiata L.) in Western U.p.

Abstract

The field experiment entitled “Effect of planting methods and seed priming on mung bean (Vigna radiata L.)” was carried out at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut- 250110 (U.P.), India., during kharif, 2020. The soil of the experimental field was well drained, sandy loam in texture and slightly alkaline in reaction. It was low in organic carbon, low in available nitrogen, medium in available phosphorus and potassium, respectively. Total sixteen treatment combinations comprised of four levels of planting methods (P1: conventional, P2: Zero tillage P3: Narrow raised bed and P4: Wide raised bed) in main plot and four levels of seed priming (T1: Control, T2: Hydro priming, T3: Molybednum, T4: Phosphorus) in sub plot were treated in split plot design with three replications. The results revealed that plant population, growth, yield attributes and yields of mung bean as influenced by planting method treatments. P4 treatment of planting method was significantly improved most of the growth parameters like plant height (at 25 and 50 DAS and at harvest) and number of trifoliate leaves/plant, number of branches/plant, number of nodules/plant, dry weight of nodules/plant and yield attributes viz., number of pods/plant, number of grains/pod and grain weight/plant followed by narrow raised bed sowing treatment (P2). In the same way, grain yield (1084 kg/ha), straw yield (2466 q/ha), biological yield (3550 q/ha) and harvest index (31.02 %) of green gram were remarkably increased under treatment P4, but it remained statistically at par with treatment P3. Different seed priming treatments also showed discernible influence on plant stand, growth and yield parameters of green gram viz., plant height at 25, 50 DAS and at harvest, number of branches/plant, number of pods/plant, number of grains/pod and grain weight/plant. All the above attributes were found remarkably higher under the application of T4 followed by treatment T3. Similarly, application of T4 significantly increased grain, straw and biological yields as well as harvest index of green gram as compared to treatment T1.On the basis of analysis, plant population at initial as well as at harvest, plant height, number of branches/plant and 1000-grain weight of green gram were not affected significantly due to interactive effect of A × B. However, positive interaction was observed between planting methods and seed priming treatments with respect to number of pods/plant, number of grains/pod, grain weight/plant and grain, straw and biological yields. Sowing of green gram on P4 along with Phosphorus (T4) turned out to be significantly superior for grain yield over rest of the treatment combinations.P4 sowing treatment significantly increased protein yield as well as nutrients i.e., N, P and K uptake by green gram crop over conventional (P1), but it was statistically at par with raised bed sowing (P3) while, protein content in grain did not influence significantly due to planting methods treatments. Significantly, the highest protein content in grain, protein yield, nitrogen, phosphorus and potassium uptake by green gram crop were recorded under application of Phosphorus (T4). On the other hand, uptake of N, P and K in straw by green gram were not affected significantly due to interaction effect of A x B. Planting method treatments failed to produce significant effect on organic carbon. However the application of P4 and T4 was appreciably improved the organic carbon. Likewise, treatment T4 significantly improved available nitrogen and phosphorus status of soil followed by treatment T3. While, available potassium in soil remained unaffected due to seed priming treatments but, numerically higher in treatment T4. All the physicochemical properties of soil did not influence significantly due to interaction effect of P x T. Sowing of green gram on P4 obtained the highest gross returns (₹ 78888/ha), highest net returns (₹ 53373/ha) with BCR value of (3.0) followed by Narrow raised bed method (P3) and Zero till (P2), whereas, the lowest gross returns (₹ 64139/ha), lowest net returns (₹ 39904/ha) and BCR (2.6) were noted under conventional sowing treatment (P1).In the same way, the lowest gross returns (₹ 50190/ha), lowest net returns (₹ 25332/ha) with BCR (2.0) was noticed under treatment T1 [control ] and the highest gross returns (₹ 85318/ha), highest net returns (₹ 59818/ha) with BCR (3.3) were registered under treatment T4 followed by treatment T3. Thus, it can be concluded from the results of present investigation that to obtain economical yield of mung bean (cv. SML-1827) and sustain soil health, the crop should be grown by adopting P4 or P3 along with seed priming combination@ phosphorus or Molybednum under well drained, sandy loam alkaline soils of western U.P.
