Yield And Yield Components

A field experiment on deep black soils during rabi season of 2014-15 to study the influence of ferti-fortification on dry matter production, yield and yield components viz., number of pods plant-1, pod weight, 100 kernel weight and shelling percentage of groundnut genotypes. Among groundnut genotypes, ICGV-00351 recorded significantly higher pod, kernel and haulm yield (2656, 1934 and 2894 kg ha-1, respectively), dry matter production at harvest (36.54 g plant-1), number of pods plant-1 (33.66), pod weight (31.81 g plant-1), 100 kernel weight (31.59 g) and shelling percentage (72.77 %) as compared to other genotypes. Among micronutrients application, higher dry matter production at harvest (43.60 g plant-1), pod, kernel and haulm yield (2789, 2051 and 3080 kg ha-1, respectively), number of pods plant-1 (34.08), pod weight (32.25 g plant-1), 100 kernel weight (31.61 g) and shelling percentage (73.21 %) recorded with soil (25 kg ha-1) and foliar (0.5 %) application of ZnSO4 (S4) as compared to control.

Genetic yield gains have been difficult to achieve within the Canada Western Red Spring (CWRS) wheat (Triticum aestivum L.) class because of stringent quality requirements and a short growing-season environment with low precipitation and high temperatures. Understanding the physiological basis of yield gains may provide breeders with better insight in selecting parents and screening tools to identify desirable genotypes. The objective of the present study was to compare four new CWRS wheat cultivars with two older cultivars, Neepawa and Marquis, for yield components and dry matter production. When grown at Swift Current, SK, for 3 yr, the average yield for the group of new cultivars was 34.3% higher than that of Marquis (P < 0.01), and 5.9% higher than that of Neepawa (P = 0.10). The new cultivars, as a group, had significantly increased kernel weight, kernels per spike, yield per spike, and spike-filling rate relative to either of the older cultivars. When cultivars were compared individually, all four of the new cultivars had significantly higher yield per spike and spike-filling rate than Neepawa or Marquis, suggesting that these factors may be closely related to the increased yields of the newer cultivars. The trend toward higher kernel weight and kernels per spike suggests that the new cultivars have increased the sink size of each tiller. The number of spikes per plant and the length of the grain-filling period do not appear to be associated with the increased yield. Harvest index of the group of new cultivars, while significantly higher than that of Marquis, has not increased significantly compared to Neepawa, probably because this group is similar in height to Neepawa.

Matter Production

The effect of four rates of nitrogen (N) fertilisation (0, 80, 160, 240 kg ha−1) on the growth and yield components of three winter wheat varieties with different maturity dates (Mv Toborzó — extra early, Mv Palotás — early, Mv Verbunkos — mid-early) was analysed in a long-term experiment laid out in a two-factorial split-plot design with four replications in the years 2007–2009. The dry matter production of the whole plant and of individual plant organs, the maximum leaf area, the area of the flag-leaf and all the yield components except the thousand-kernel weight were significantly the greatest in the N160 or the N240 treatments. Averaged over the varieties and years the grain yield in the N treatments was N0: 5.5, N80: 7.1, N160: 7.3 and N240: 7.5 t ha−1. Averaged over N treatments and years the variety Mv Verbunkos had the highest dry matter production, stem mass, spike mass, number of grains per spike and grain yield. Mv Verbunkos had the greatest leaf area in the favourable years of 2008 and 2009 and the greatest flag-leaf area in 2008. Averaged over N treatments and varieties the dry matter production per plant, the leaf and stem mass, the number of spikes per square metre and the thousand-kernel weight were greatest in 2007. The spike mass was lowest in 2007 and had higher, very similar values in 2008 and 2009. The maximum leaf area per plant, the area of the flag-leaf, the number of grains per spike and the grain yield were highest in 2008. The values and dynamics of the growth parameters gave a good characterisation of the effect of the treatments (N fertilisation, variety, year) on plant production (yield, yield components) in various stages of growth.
