(2004) conducted varietal trials of wheat crop with phosphorus application and reported the higher grain and biomass yield as well as improved phosphorus harvest index and phosphorus use efficiency in Wh-711 and PBW-343.
The parents were different in some quantitative traits (Table 1) T-test showed that the results of hybridizing of the parents were meaningfully different from traits like length of ears, weight of seed in plant, ear density ratio, and number of days till appearance of ear, and physiologic growth and harvest index.
The F1 hybrids of Cross A manifested more 1000-seed weight and harvest index than both the parents while in Cross B plant parameters flag leaf area, spike length, 1000-seed weight, seed yield main spike-1 and harvest index showed greater F1 mean values than parents (Tables 3and4).
From this point on the values of grain yield, biomass yield, straw yield and harvest index using the ideal dose of the growth regulator for a maximum 10% lodging were estimated.
The maximum plant height (231.9 cm), grains count per cob (483.67), 1000-grains weight (255.03 g), grain yield (5.64 t ha-1), biological yield (17.32 t ha-1) and harvest index (34.50%) was observed where zinc was used @ 27 kg ha-1.
Maize after inoculated soybean recorded the highest harvest index, which was significantly (P < 0.05) greater than the rest of the treatments (Table 3).
Optimum plant height is considered as an important trait for avoiding lodging, thus maximizes harvest index. On an average, water stress caused -5.06 cm reduction in plant height yet, minimum reduction was observed in Sarsabz (-3.00 cm) while maximum in Kiran (-7.37cm) followed by Hero (-6.47) and PBGST-03 (-6.18 cm) (Fig.
Highest harvest index was attained with B application of 3.69, 3.75 and 3.21 kg ha-1 during first year at 100-, 75- and 50% RN, respectively.
Data presented in Table-1 indicated that date of sowing was significantly effect on plant height at various days, harvest index and yield of cress.
