CONTRIBUTION OF THE MAIN STEM AND TILLERS OF SOME CULTIVARS OF WHEAT (TRITICUM AESTIVUM L.) UNDER DIFFERENT LEVELS OF NITROGEN FERTILIZER

Pot experiment is carried out at the greenhouse belongs to the college of Education-university of Al-Anbar during Winter season 2013/2014 to investigate the effect of application of different levels of bat guano (0, 4 and 8gm) on some yield traits for two bread wheat Triticum aestivum L. Cvs, one is local cv. (Aliz) another one is imported from Australia (Eratom). The experimental treatments are distributed according factorial experiment arrangement using completely randomized blocks with three replicates. Some traits are measured as spikes no per plant, spike length, spike weight, grains nos. per spike and grains weight per pot. Results reveal that bat guano application of 8gm is significantly superior in the average of. It thus could be concluded that the application of bat guano at 8gm alone is the better than 4gm in some traits. However, the genetic affinity of local cv is dominated with 4gm application and of imported cv is to 8gm application. Therefore, it could be recommended to test the application of bat guano on the two cultivars across field environment

Interplant Competition

Three spring wheat (Triticum aestivum L.) genotypes (Neepawa, Siete Cerros and M1417) were subjected to four levels of tiller removal (MS remaining, MS + T1 remaining, MS + T1 + T2 remaining, control) at three plant densities (two, four and eight plants per 15-cm-diameter pot) in a controlled environment to assess the effects of interplant and intraplant competition on stem dimensions and yield-related traits of genotypes with diverse tillering habits. Both types of competition resulted in reduced kernel weight and main stem grain yield and increased yield per pot. Interplant competition also reduced harvest indices while intraplant competition reduced main stem length and main stem diameter. The oligoculm genotype, M1417, was more sensitive to interplant competition than Siete Cerros and Neepawa. The increased sensitivity of M1417 appears to result from plant mortality combined with the inability to maintain kernel mass under severe interplant competition.Key words: Triticum aestivum, wheat (spring), tiller removal, grain yield, plant competition.
