| Effect of cytozyme on yield and yield components in
wheat (Triticum aestivum L.) M.M. RAJPUR, A.J. MALIK, H.K. JARWAR and M.K. ABASSI Sind Agriculture University, Tandojam, Pakistan. The Plant growth regulators are playing an important role in agriculture since last 50 years. Plant growth regulators like Indole acetic acid, Naphthalene acetic acid, Gibberellic acid, 2, 4-Dichloro phenoxy-acetic acid etc. are used to bring about changes in the physiological process of the plant. Recently however, cytozyme has been added to the list of plant growth regulators. There are different formulations of this biologically derived active enzyme compound, e.g. Cytozyyme seed+, Cytozyme soil+ and Cytozyme crop+ which also augment nutritional support for plant. According to SILVA & STUTTE (1980) cytozyme is a plant biostimulant bacterial enzyme+cytokinin+auxin and micronutrient. They observed that, application of cytozyme increased grain yield of rice from 9.2 to 17.0 percent over control. Present study has been carried out keeping in view the potential of cytozyme for taking the maximum crop yields with advantage. Cytozyme is used on many crops e.g. wheat, rice, cotton, corn, forage, potatoes, vegetables and fruits, for increased emergence rate, seeding vigour through improved plant support, improved crop quality and greater yield (METCALF 1970 ; ASGHAR et al. 1981). Materials and Methods The studies were under taken to observe the effect of different formulations of cytozyme on wheat cultivar P94. The experimental material was sown in split plot desine with four replications. The 12 sub-plots of each replication with three different formulations of cytozyme were applied on each of four sub-plots, that is: A1 Seed+ : seed was soaked in cytozyme seed+ solution for 2 hours before sowing. A2 Soil+ : It was sprayed on soil surface after final seed bed preparation and before sowing. A3 Crop+ : The formulation was sprayed on the crop when it was at pre-booting stage. Four doses of each formulation including control were used. The doses of seed+ formulation were 0.125, 0.250 and 0.375 litres per hectare and for soil+ and crop+ were 0.425, 0.850 and 1.275 litres per hectare for D1, D2 and D3 respectively, compared to control (D0). The soil was loamy in texture with pH value of 7.4 having very low organic matter. The data was recorded on spike number, spikelet number, floret number, grain number, seed index and grain yield per plot. Results and Discussions Average number of spikes per plant is given in Table 1, It shows that higest average number of 2.55 spikes per plant was observed from untreated crop. The next high number 2.4 was produced by Crop+ formulation at D3 level and lowest number of 2.20 spike per plant was provided by seed+formulation at D2 level. However, all these differences were found to be non-significant. Although differences in spikelet number (Table 1) of three formulations at all doses were non-significant, yet it was observed that all the treatments increased spikelets per spike over that of control. Meximum spikelets were recorded from crop+ formulation at higher dose and the lowest spikelet number was provided by seed+ formulation. |
