IX. Yield contributing characters of mustard

The yield contributing characters, namely, number of siliquae per plant, length of siliquae (cm), number of grains per siliqua, weight of siliquae per plant (g), weight of grains per plant (g) and thousand grain weight (g) recorded at harvest are presented in Table 24 and depicted in Fig. 20 and 21.

Table 24. Yield contributing characters of mustard as influenced by different treatments.

1. Number of siliquae per plant

Effect of preceding treatments

Data indicated that mustard grown after T₇ noted significantly higher number of siliquae per plant than all the remaining treatments except T₆, where the differences were of the similar magnitude during both the years. T₆ as preceding treatment showed superiority over the remaining treatments, but its differences between with were not up to the mark. The number of siliquae did not differ due to the residue of T₂, T₅ and T₈ as well as T₈ and T₄, during both the years though the treatments were superior to control.

Effect of fertilizer levels

In both the years, application of Fertilizers 90:45:45 kg ha^-1 (M₂) produced significantly higher number of siliquae compared to that of Fertilizers 45:45:45 kg ha^-1, which in turn was also superior over control.

Interaction effect

Interaction effects were not significant.

2. Length of siliquae (cm)

Effect of preceding treatments

Data showed that mustard following T₇, T₆ and T₃ produced significantly longer siliquae compared to all the remaining treatments during both the years, but the differences between former three treatments were not up to the mark. Similarly, remaining treatment did not show marked difference in residual effects.

Effect of fertilizer levels

Application of Fertilizers 90:45:45 kg ha^-1 (M₂) and Fertilizers 45:45:45 kg ha^-1 (M₃) resulted in significant increase in length of pods compared to control, but the differences between former two levels were not up to the mark during both the years.

Interaction effect

Interaction effects were not significant.

3. Number of grains per siliqua

Effect of preceding treatments

The residual effect of T₇ and T₆ noted significantly higher number of grains per siliqua compared to the remaining treatments, but both the treatments behaved similarly with each other in respect of number of grains per siliqua during 2000-2001. Similarly, T₆ and T₃ proved significantly superior to T₂, T₅, T₈, T₄ and T₁, but the differences between former two treatments was of the similar order. T₂, T₅ and T₈ did not show marked variation though these treatments were superior to control. Similar trend was noted during 2001-2002, except that the differences between T₇, T₆ and T₃ were of the similar magnitude.

Effect of fertilizer levels

The direct effect of application of Fertilizers 90:45:45 kg ha^-1 as well as Fertilizers 45:45:45 kg ha^-1 significantly increased the number of grains per siliqua compared to control while the differences between former two treatments did not show a significant variation during both the years.

Interaction effect

Interaction effects were not significant.

4. Weight of siliquae per plant (g)

Effect of preceding treatments

In 2000-2001, T₇ showed significant residual effect ultimately resulting in significant increase in the weight of siliquae (g) per plant compared to the remaining preceding treatments followed by T₆ and T₃. T₂ and T₅ also showed profound residual effect compared to T₈ and T₄, but were superior to control. While the differences between T₂ and T₅, T₅ and T₈ as well as T₈ and T₄ were of the similar magnitude. The trend of results was similar during 2001-2002, except that the differences between T₆ and T₃ were not conspicuous.

Effect of fertilizer levels

During both the years, application of Fertilizers 90:45:45 kg ha^-1 significantly increased the weight of siliquae (g) per plant compared to Fertilizers 45:45:45 kg ha^-1, which in turn was also superior over control.

Interaction effect

The interaction effect was found to be significant during 2000-2001 and is presented in Table 25. It was seen that fertilization to hybrid rice as preceding treatments (T₇) combined with Fertilizers 90:45:45 kg ha^-1 (M₂) to mustard produced significantly higher weight of siliquae per plant (21.23 g) followed by T₃M₂ (20.50 g), T₆M₂ (20.17 g) and T₇M₃ (20.15 g). This indicated that fertilization to hybrid rice had significant residual effect in obtaining highest weight of siliquae (g) per plant.

Table 25. Interaction of preceding treatments × fertilizer levels on weight of siliquae per plant (g) of mustard during 2000-2001.

5. Weight of grains per plant (g)

Effect of preceding treatments

In 2000-2001, T₇ showed significant residual effect ultimately resulting in significant increase in the weight of grains per plant compared to the remaining preceding treatments followed by T₆ and T₃. T₂ and T₅ also showed profound residual effect compared to T₈, T₄ and control. While the differences between T₂ and T₅, as well as T₈ and T₄ were of the similar magnitude. The trend of results was similar during 2001-2002, except that the differences between T₆ and T₃ as well as T₅ and T₈ were not conspicuous.

Effect of fertilizer levels

In both the years, application of Fertilizers 90:45:45 kg ha^-1 significantly increased the weight of grains per plant as compared to Fertilizers 45:45:45 kg ha^-1, which in turn was also superior over control.

Interaction effect

Interaction effects were not significant.

6. Thousand Grain weight (g)

Effect of preceding treatments

Data indicated that mustard grown after T₇ noted significantly higher thousand grain weight (g) than all the remaining treatments, except T₆, where the difference was of the similar magnitude during both the years. T₆ as preceding treatment showed superiority over the remaining treatments, but the difference between T₆ and T₃ was not up to the mark. The thousand grain weight (g) did not differ due to the residue of T₂, T₅ and T₈; T₈ and T₄, as well as T₄ and T₁, during both the years. During 2001-2002, T₅, T₈ and T₄ as well as T₈, T₄ and T₁ behaved similarly with each other.

Effect of fertilizer levels

During 2000-2001, application of Fertilizers 90:45:45 kg ha^-1 significantly increased the 1000 grain weight compared to Fertilizers 45:45:45 kg ha^-1, which in turn was also superior over control while during 2001-2002 application of Fertilizers 90:45:45 kg ha^-1 did not show marked variation compared with Fertilizers 45:45:45 kg ha^-1.

Interaction effect

Interaction effects were not significant.

X. Grain and stover yield (q ha^-1) of mustard

The grain and stover yield of mustard (q ha^-1) as influenced by different treatments is presented in Table 26 and depicted in Fig. 22 and it shows that all the treatments were significantly powerful over control during both the years.

Table 26. Grain and stover yield (q ha^-1) of mustard as influenced by different treatments.

Effect of preceding treatments

Fertilization to hybrid rice crop with organic manure particularly gliricidia had significant residual effect in enhancing subsequent mustard grain yield in comparison with the remaining treatments. The grain yield increase in mustard was to the extent of 93.10, 89.97 and 58.15% over control by T₆, T₃ and T₂ in 2000-2001 and 147.66, 143.16 and 95.70% in 2001-2002, respectively. The benefit of residue was in the order of T₆>T₃>T₂>T₅>T₈ and T₄ showing their superiority over the control during both the years, as well as when, the data were pooled. The difference between T₂ and T₅ due to residue was not conspicuous.

The residual effect of T₇ was found significantly higher than all the remaining treatments in case of stover yield during both the years, as well as in the pooled data. This was followed by T₆, T₃, T₂, T₅, T₈ and T₄, which were superior over control in their residual effect. The differences between the residue due to T₆ and T₃ as well as T₂ and T₅ were not significant in 2000-2001 and in pooled data, while in 2001-2002, T₂ and T₅ as well as T₅ and T₈ did not show markedly variation in their residual effect.

Effect of fertilizer levels

In the case of grain and stover yield it was noted that all the treatments were significantly superior over control. Application of Fertilizers 90:45:45 kg ha^-1 recorded significantly higher grain and stover yield compared to Fertilizers 45:45:45 kg ha^-1 and control during both the years. Similarly, application of Fertilizers 45:45:45 kg ha^-1 showed in superiority over the control during both the years. Similar trend was noted, when the data were pooled.

Interaction effect

The interaction effect of treatments in grain yield (q ha^-1) of mustard was significant, which is presented in Table 27. The grain yield increased significantly due to direct application of fertilizers to mustard crop irrespective of the residual effect. Fertilization of preceding treatment (T₇) to hybrid rice combined with Fertilizers 90:45:45 kg ha^-1 (M₂) to mustard produced significantly higher grain yield (13.66 q ha^-1), followed by 13.25 (T₃M₂), T₆M₂ (13.01 q ha^-1) and T₇M₃ (12.99 q ha^-1) in 2000-2001, while in 2001-2002 the maximum yield was noted due to T₇M₂ (13.98q ha^-1) followed by T₇M₃ (13.73 q ha^-1), T₃M₂ (13.38 q ha^-1). Similar trend was also noticed, when the data was pooled. This indicated that fertilization to hybrid rice had significant residual effect in enhancing subsequent mustard grain yield.
